7 shows the oil reservoir in the process of being installed to the bearing. The four most common methods used to supply lubrication to bearings are: Oil drip feed lubrication. Lubrication Systems. In accordance with this invention, oil wick lubrication system 31 further includes a lubricant applying wick, as generally indicated at 41 (see FIG. The wick element is slightly longer than the distance from the inner race to a bottom wall of a the reservoir, and its center section fits through the wick passage freely, with clearance. 5. The oil is thrown upward as droplets or fine mist and provides adequate lubrication to valve mechanisms, piston pins, cylinder walls, and piston rings. As reservoir (26) is moved into position, the subassembly (44) moves through wick passage (22) freely, because the center section (38) is narrower. Typically, the motor includes a rotor shaft, a bearing support and a self-aligning bearing supported thereby journalling the rotor shaft of the motor. In this manner, both the radial and thrust surfaces (i.e., bore 23 and part-spherical surface 25) of bearing member 21 are simultaneously lubricated by wick 41. Designed to lubricate individual machines or complete plants, automatic lubrication systems provide proper, precise lubricant replenishment to all required points, enabling a range of benefits in the process. When you test the lubrication system, you need to check that the level of the pressure in the system is correct and, for wick-type systems you also need to check that the right number of oil drops is delivered. Check that the sump tanks are ready for operation. Each is suited for certain types of applications. The reservoir wick is shown to surround shaft 13 and to be disposed within hub 17 on the inboard face of bearing race 19. Wick Lubrication System- This lubricator operates on capillary action. Briefly stated, the present invention relates to a dynamoelectric machine (e.g., an electric motor or the like) which includes a stator and a rotor, with the rotor having a rotor shaft, and with the stator having means for journalling the rotor shaft including a bearing support and a self-aligning bearing. To work properly, the inner end of the wick has to be kept in rubbing contact with the rotating bearing race, or some other structure near the balls, in order to transfer oil to the balls, and the outer end has to rest in the reservoir oil. . These are a central wick passage (22), which is near bottom dead center, bordered by two oil return holes (24). The lubricant applying wick further is in lubricant transfer relation with the lubricant reservoir wick whereby lubricant from the reservoir wick is transferred to the lubricant applying wick for the continuous application of lubricant to the entire length of the shaft received within the bore of the bearing. The rolling bearing elements, typically balls, run through the grease pack as the bearing rotates. 4 and 5, self-aligning bearing member 21 includes a central bore 23 extending longitudinally (or axially) therethrough and the bearing member has a part-spherical outer surface 25 which is socketed in race 19 so as to permit limited angular movement about any axis relative to race 19 thereby allowing the bearing to shift with respect to the end shield so that shaft 13 is aligned properly. Oil Mist Lubrication Working Principle. Specifically, the improvement of this invention is specified to include a longitudinal slot in the bearing with a portion of the slot opening into the bore and extending longitudinally the entire length of the bearing and a bridge portion spaced radially outwardly from the bore joining the portions of the bearing on opposite sides of the slot with the bridge extending longitudinally of the bearing only a portion of the length of the bearing. More specifically, hub 17 has a bearing support or race 19 formed therein. 5), as indicated by dimension L. In FIG. 5. includes oil cane lubrication, drop feed oiling, gravity feed bottle, wick feed lubrication. Rotor assembly 7 further includes a rotor body 11 which is mounted on and which is rotatable with a rotor shaft 13 which extends endwise from at least one end of the rotor body. Referring now to FIG. 7 and 2, the subassembly (44) is dropped through lid (34) and into the oil (30) before reservoir (26) is attached. a) drop feed lubricator system. ;ASSIGNOR:BURTON, STEPHEN J.;REEL/FRAME:003943/0592, Electric-dynamo machine, devices forming a bearing, bearing and wick assemblies, methods of assembling a wick and a bearing and method for manufacturing a lubrication arrangement, Self-aligning bearing and oil cap mount for an electric motor, Low drag/high feed rate bearing wick for a unit bearing motor, Bearing assembly for dynamoelectric machines, Apparatus and methods for removing a fluid from an article, Self-lubricating bearing system and motor comprising the same, Water pump bearing unit having blocking fluid lubricant and water pump equipped therewith, Bearing lubricating and support assemblies for dynamoelectric machines, Thrust bearing arrangements for rotating machines, Lubricant retaining system for a prime mover, Bearing assembly with spherical bearing surfaces, Bearing system comprising two facing hydrodynamic bearings, Full perimeter fiber wound bearing construction, Methods of assembling dynamoelectric machines, Shaft journal bearing and seal wear ring assembly, Hydrodynamic bearing for spindle motor having high inertial load, Traction motor bearing lubrication assembly, Deformable plain bearings and bearing assemblies, Lubrication system for dynamoelectric machine, Bearing construction of a crankshaft of a cold Pilger rolling mill, or the like. 2; FIG.

Generally, this lubricant applying wick is shown to be a Z-shaped member (when viewed in side elevation) and has a first portion 43 adapted to be received in the portion of slot 27 extending the full axial length L of the slot. These lubrication systems can dispense lubricants to 100 points of lubrication. Oil can be introduced to the bearing in many ways, such as drip-feed, wick-feed, pressurized circulating systems, oil bath or air-oil mist. In the engine, dippers on the connecting-rod bearing caps enter . Country of Origin USA (subject to change) Product Description. 7-66. 4,219,245. As the elevator operates, the hoist ropes are cleaned. 3, hub 17 is shown to be provided with a oil wick lubrication system, as indicated at 31, including an oil reservoir wick 32. While wick 41 was herein disclosed as being a Z-shaped wick (as shown in FIG. The one shown in Fig. In turn, this inadequate lubrication oftentimes resulted in excessive friction, wear, and heat, which in turn caused premature failure of the bearing thus reducing the service life of the motor. Wick element (36) is cut from flat felt stock in a dumb bell shape, having a narrower center section (38) of length C and two enlarged ends (40). ;ASSIGNOR:BURTON, STEPHEN J.;REEL/FRAME:003943/0592, Free format text: In accordance with this invention, bearing 21 is provided with a slot 27 having a portion opening into bore 23 and extending longitudinally the length of the bearing member. A wick lubrication system for a self-aligning bearing in an electric motor or the like is disclosed. Oil-mist lubricating systems should operate at pressures of ___ psi. Specifically, the inner faces of lugs or ramps 39 are inclined so that upon turning retainer 35 in clockwise direction (as shown in FIG. As shown in FIG. 1. Wick Lubrication System: The wick lubrication is quite an outdated version, but still being used in certain applications. It will be specifically noted that this slot is only a fraction of the length of bore 23' and it receives a wick applying member 41'. Gravity feed system: Oil holes, Oil cups, and wick feed lubricators. Other objects and features of this invention will be in part apparent and in part pointed out hereinafter. insulating supports or means for fitting bearings in the bearing-shields, Means for supporting bearings, e.g. Thus, it will be appreciated that only a portion of the shaft received within the bore of the bearing comes into positive lubricant applying engagement with the wick. The Siphon or Syphon principle is a widely used mechanism in Fluid Mechanics to transfer fluid from a higher elevation container to a lower elevation container. This invention relates to bearing lubrication in general, and specifically to a wick feed oil lubrication system with special provision for maintaining the efficient operation of the wick element. 4,219,245. Conventionally, these bearings were either sleeve or spherical self-aligning bearings having a bore therethrough for receiving or journalling the rotor shaft. Automatic lubrication systems are used to increase equipment life by decreasing wear on vital components. Wick (cotton or wool s) carries oil from the well to the shaft sleeve. This helps administer the right amount and keep the gear oil on the metal gears. Standards CE Certified; EAC Certified. Step 3: Locate Lubrication Ports. Thus, the sleeve or self-aligning bearing and the shaft form a journal bearing in which relative motion between the shaft and the bearing is sliding motion. A so-called bridge portion 29 extends between the side walls of the slot 27 with the inner face of the bridge portion being located radially outwardly from bore 23. Typically, the motor includes a rotor shaft, a bearing support and a self-aligning bearing supported thereby journalling the rotor shaft of the motor. . 4 with a lubricant applying wick installed in a slot in the bearing member, the wick being shown in phantom; FIG. suspension (16). The most common systems are: 2. As shown in FIG. 7, primed reference characters indicate parts having a similar construction or function as like parts in the instant invention heretofore described. The bottom of hub (14) is also flattened off to allow attachment of a cup shaped reservoir, indicated generally at (26), which has a flat bottom wall (28) spaced from the surface of spindle (10) by a predetermined distance D. Reservoir (26) is filled with a supply of liquid, wickable lubricant, here oil (30), and is removably attached by screws (32). The shaft surface speed in this case is 30 rev/sec 5 in. Ring lubrication system is generally used for lubrication of: A. Vertical bearings: B. Horizontal bearings: C. Inclined bearings: D. None of these The Splash system mostly works in connection with the pressure system in an engine, some parts being lubricated by the splash system and the other by a pressure system. The aim of the gravity system, as of all lubrication systems, is to provide a reliable means of supplying the bearing surfaces with the proper amount of lubricating oil. As shown in FIG. 6-29), oil is splashed up from the oil pan or oil trays in the lower part of the crankcase. 5 to 10. Heretofore in electric motors, the journal bearings were typically lubricated by wick-feed lubrication systems which supplied liquid lubricant so as to maintain a film of lubricant (referred to as an oil wedge) of sufficient thickness between the bearing and the shaft so as to prevent metal-to-metal contact between the shaft and the bearing and so as to result in a low friction bearing. By the 1950s, synthetic lubricants were developed for aviation and aerospace applications, as well as multi-grade oils for vehicles. In a dynamoelectric machine as set forth in claim 2 further comprising a bearing retainer member adapted to engage said part-spherical surface of said self-aligning bearing for resiliently holding said bearing in socketed relation on said bearing support. Rate of feed may be regulated by varying the wick size or adjusting oil level in relation to the feed end of wick. A. increase pressure and distribute lubricant. Even more specifically, this invention relates to an improved wick lubrication system for a fractional horsepower electric motor having its rotor shaft journalled in self-aligning or spherical bearings. ;ASSIGNOR:LEDERMAN, FREDERICK E.;REEL/FRAME:006174/0385, Free format text: Further in accordance with this invention, it will be noted that lubricant is also applied to the outer face of bearing member by excess lubricant from wick 41 thereby to insure the interface between part-spherical surface 25 of bearing member 21 and race 19 is adequately lubricated. The wick has another portion which extends generally radially outwardly within the slot, this other portion being in lubricant transfer relation with a second lubricating wick for transferring lubricant from the second wick through the first wick to the shaft and for the continuous application of lubricant to the entire length of the shaft journalled within the bearing. Typically, the oil is pumped through an . PATENT EXPIRED DUE TO NONPAYMENT OF MAINTENANCE FEES UNDER 37 CFR 1.362. Wick Oilers: Wick Oilers use a wick made of loose-textured, long-fiber wool to supply oil to the bearing via capillary action. Another method is to attach a sec- 5, wick portion 43 also extends the length of bearing member 21. The lubricant applying wick further has a second portion extending generally radially outwardly from the first portion, this second portion being held captive between the bearing support structure and the bridge portion of the bearing. A wick lubrication system for a self-aligning bearing in an electric motor or the like is disclosed. Referring now to FIG. Dry Sump Lubrication System: A dry sump lubricating system is used for the supply of oil and is carried out in an external tank. Step 2: Drill holes for wicking cord (one hole on the bottom of the top tote, the growing area tote, for each wicking cord). 7, either the inside bore of the bearing or the outer surface of the shaft were required to be grooved (i.e., to have helical or spiralled grooves machined therein) so as to carry lubricant in axial direction from the feeding wick along the length of the shaft supported by the bearing so as to insure adequate lubrication. Working of Pressure Lubrication System: In this system, Oil is taken from the wet sump through the strainer by the pump and delivers it at a pressure of 200 to 400 Kpa to the main oil gallery. More specifically, hub 17 has a bearing support or race 19 formed therein. Typically, the motor includes a rotor shaft, a bearing support and a self-aligning bearing supported thereby journalling the rotor shaft of the motor. The oil pressure ranges from 100 to 250 psi. Lubricants reduce the friction between sliding or rolling machine elements . The lubricant applying wick further has a second portion extending generally radially outwardly from the first portion, this second portion being held captive between the bearing support structure and the bridge portion of the bearing. Pressure Feed by Hand Pump iii. How do I make a Wick System? FIG. b) Wet sump lubrication system. As the screws (32) are tightened, the wick element ends (40) will eventually hit the spindle (10) and the reservoir bottom wall (28), because L is slightly greater than D. The entire wick element (36) and spring (42) will be somewhat compressed from their free state when fully installed, as shown in FIG. 2. Linear guiding device with rail race lubricating elements. Wick Feed Lubrication System. Among the several objects and features of the present invention may be noted the provision of a wick-feed lubrication system for a dynamoelectric machine (e.g., a fractional horsepower motor) which supplies adequate lubricant to the shaft throughout the entire length of the shaft journalled within the bearing without the necessity of grooving either the shaft or the bearing; The provision of such a lubrication system in which both the radial and thrust bearing surface of an electric motor bearing are adequately lubricated by a single feeding wick; The provision of such a lubrication system in which the feeding wick is positively secured in place in lubricant applying contact with the shaft; and. Reference may be made to U.S. Pat. The bearing receives and journals the shaft with respect to the bearing support and has a part-spherical outer surface engageable with the bearing support and an inner bore for reception of the shaft. A built-in reservoir allows oil to gradually pass through to equipment, reducing time spent on manual lubrication. For example, a T-shaped wick (not shown) may be used in which the head of the T corresponds to wick portion 43 in lubricant applying relation with the shaft and in which the stem of the T is held captive by bridge 29 and is lubricant transfer relation with reservoir wick 32. 1, 2 and 6, a vehicle wheel bearing includes an inner race or spindle (10). 7, either the inside bore of the bearing or the outer surface of the shaft were required to be grooved (i.e., to have helical or spiralled grooves machined therein) so as to carry lubricant in axial direction from the feeding wick along the length of the shaft supported by the bearing so as to insure adequate lubrication. Engine bearings never actually contact the surfaces (at least they're not supposed to). Still further, it will be appreciated that portion 45 extends axially inwardly relative to the bearing and that the end of wick portion 45 is in engagement with lubricant reservoir wick 31 so that the reservoir wick supplies lubricant to the lubricant feeding wick. This lubrication level is about 20% of the full oil-feed rate of 5.6 in. Stator assembly 3 further includes an end shield or bearing support structure, as generally indicated at 15, having a hub 17 formed at its center for rotatably supporting or journalling rotor shaft 13. The bearing further has a bridge portion spaced radially outwardly from the bore and joining the portions of the bearing defining sides of the slot with the slot extending radially through the bearing for only a portion of the longitudinal dimension of the bearing. Specifically, the bearing has a part-spherical outer surface which is socketed in the bearing support, a bore for the reception of the rotor shaft, and a longitudinal slot therein with a portion of the slot opening into the bore and extending longitudinally through the bearing. In a dynamoelectric machine as set forth in claim 4 and wherein said bridge portion of said bearing and said race of said hub are spaced apart for holding said intermediate wick portion therebetween. 4, slot 27 has a width, as indicated by dimension W, and a length (shown in FIG. 6 is a side elevational view of the lubricant applying wick; and. Wick Feed Lubrication System - China Manufacturers, Factory, Suppliers. 5), as indicated by dimension L. In FIG. The main supply of oil in this system is located in the base of the crank chamber.
