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. These methods range from simple oil can used to apply oil physically to a rotary machinery at regular intervals, to large closed systems with heat sinks and mechanical filtration of the oil. Reference may be made to U.S. Pat. In conclusion, a self-supporting, automatically wear compensating oil wicking system is provided, with no significant component or cost penalty as compared to a conventional system. Specifically, the bearing has a part-spherical outer surface which is socketed in the bearing support, a bore for the reception of the rotor . 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. Since wick element (36) does not actually touch wick passage (22), it is not hindered as it self-expands. Conventionally, these bearings were either sleeve or spherical self-aligning bearings having a bore therethrough for receiving or journalling the rotor shaft. 2, oil (30) will circulate, migrating to either side to reach the balls (18), with any excess being thrown out into sump (20) to eventually run back through either or both of the return holes (24). 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. 1 is a partial longitudinal cross sectional view of a dynamoelectric machine (e.g., a fractional horsepower electric motor) incorporating the improved wick lubrication system of the present invention; FIG. A total-loss oiling system is an engine lubrication system whereby oil is introduced into the engine, and then either burned or ejected overboard.

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. Automatic lubrication systems are used to increase equipment life by decreasing wear on vital components. Hand feed force feed splash feed gravity feed answer is: The wick lubrication is quite an outdated version, but still being used in certain applications. Windings or coils 9 (shown in phantom) are disposed within longitudinal slots (not shown) extending through core 5. 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. Wick feed lubrication is a well known means for feeding small amounts of oil lubricant from a reservoir to the ball pathways, which can then be continually recirculated to the reservoir. 1. FIG. In FIG. 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. 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. 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. Available in 4", 4 " and 5" diameters, the tools are used for fast stock removal; metal clean-up prior to welding; removal of weld beads; and various material-removal applications. Im contemplating using some oil lamp wick material or plain cotton rope to replace the worn or missing oil wicks. 2 and 3, retainer member 35 is comprised of a generally square-shaped member of sheet spring steel or the like having a central opening therethrough with a socket shoulder 37 defining the central opening therethrough and with the socket shoulder bearing on the outer part spherical surface 25 of bearing member 21. Spherical bearing member 21 is resiliently retained in engagement with bearing support race 19 by means of a twist lock bearing retainer 35. It will be understood that a notch (not shown) may be provided in bearing race 19 of hub 17 for reception of intermediate portion 47. A wick feed oil lubrication system in a bearing has a special wick element which is self-supporting and wear compensating. 3 illustrating the end of a spherical, self-aligning bearing member; FIG. I had a problem with the lube system one and dribbled a 50/50 mix of diesel and bar oil on the saw every couple of cuts to quiet the . Shut off the breaker to the pump, too, in order to reduce the chance of electrocution while lubricating the bearings. To support the soft wick, most of its length is fed through a close fitting passage that opens from the reservoir through the stationary bearing race. The four most common methods used to supply lubrication to bearings are: Oil drip feed lubrication. Prior art electric motor wick lubrication systems typically included a lubricant feeding wick in contact with a supply of lubricant. 1. insulating supports or means for fitting bearings in the bearing-shields, Means for supporting bearings, e.g. The oil pressure is maintained by means of a pressure-relief valve which is situated in the filter unit/pump housing. Oil serves as . 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. by wicks, GENERAL MOTORS CORPORATION, A CORP.

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. Reference may be made to U.S. Pat. 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. Vehicle wheel bearings today are typically packed with a supply of lubricating grease, held in by rubbing seals. As shown in FIG. Step 3: Locate Lubrication Ports. 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'. I'm testing my home made prototype drip feed oiler for my vintage lathe. Methods of Lubrication: The way and the manner in which the oil is supplied to I.C. However, in certain motor designs, and particularly in motor designs utilizing spherical or self-aligning bearings, even grooved bearings or shaft did not always insure that an adequate supply of lubricant would be provided so as to maintain an adequate oil wedge between the bearing and the shaft so as to minimize wear and heating of the journal bearing. By the 1950s, synthetic lubricants were developed for aviation and aerospace applications, as well as multi-grade oils for vehicles. 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. ASSIGNMENT OF ASSIGNORS INTEREST. Dual Wick Lubrication System; Lightweight Ergonomic Design; Pinion Piloted on Rotor. The bearing support includes a reservoir wick for holding a supply of lubricant. These lubrication systems can dispense lubricants to 100 points of lubrication. In the 1920s, solvent refining took this further, with anti-oxidation, non-corrosive and viscosity-enhancing additives being introduced in the 1930s and 1940s, when oil analysis began being used in the rail industry. Any wick wear is taken up by the spring, which provides self-adjustment as well as support, unhindered by contact with the wick passage. 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.
