Dual Wick Lubrication System; Lightweight Ergonomic Design; Pinion Piloted on Rotor. 1. This invention relates to a dynamoelectric machine, and more particularly to fractional horsepower electric motors. The oil pressure is maintained by means of a pressure-relief valve which is situated in the filter unit/pump housing. 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. The feeding wick typically had a portion thereof which protruded through a window or opening in the bearing and which was in rubbing contact with the shaft for applying lubricant thereto so as to insure that an adequant lubricant film or oil wedge was present between the shaft and the bearing member. Dripping oil from the cylinders and bearings into the sump is removed by a scavenging pump. Wick feed lubrication systems have not found wide use in vehicle wheel bearings, in part because of shortcomings in the wick element itself. This system allows long intervals between maintenance of bearings and prevents the bearings becomes too much 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. Dual wick lubrication system saturated with gear oil for extended gear life over 700 hours. insulating supports or means for fitting bearings in the bearing-shields using sliding-contact or spherical cap bearings radially supporting the rotary shaft at both ends of the rotor.

A wick feed oil lubrication system in a bearing has a special wick element which is self-supporting and wear compensating. 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. 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. 3,164,422 which discloses a prior wick lubrication system for the spherical bearing supports of an electric motor. As shown in FIG. Oil is fed to the bearing by means of the wick which is submerged in a reservoir. Gravity feed system: Oil holes, Oil cups, and wick feed lubricators. The wick is a soft, oil absorbent material capable of capillary action. 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). Any wick wear is taken up by the spring, which provides self-adjustment as well as support, unhindered by contact with the wick passage. Oftentimes, as shown in FIG. Wick Feed Lubricator: Figure 8.7 show the assembled drawing of wick feed lubricator. Wick (cotton or wool s) carries oil from the well to the shaft sleeve. Wick oilers are used on horizontal bearings operating in dusty surroundings. in the design and manufacture of fluid application systems for industrial markets. Typically, the motor includes a rotor shaft, a bearing support and a self-aligning bearing supported thereby journalling the rotor shaft of the motor. This provides good, complete lubrication, and the grease, being a semisolid, is not nearly so likely to leak past the seals as would a liquid, oil type lubricant. Lubrication Systems. This is best illustrated in FIG. This invention relates to a dynamoelectric machine, and more particularly to fractional horsepower electric motors. 3. Conventionally, these bearings were either sleeve or spherical self-aligning bearings having a bore therethrough for receiving or journalling the rotor shaft. Wick Lubricator iii. 276.

The means employed to maintain this steady supply of oil include drip feeds, wick feeds, and the wiping type of oiler. c) ladder lubricator system. 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. When installed, the wick element and supporting spring are compressed between the bearing spindle and bottom wall of the oil reservoir, running through a loosely fitting passage in the surrounding hub. 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. As shown in FIG. Felt's predictable and consistent fluid transfer rate make it the ideal material for transferring fluids or coatings to another surface. A filter/lubricator ensures efficiency and reduces wear on the pump. 4 with a lubricant applying wick installed in a slot in the bearing member, the wick being shown in phantom; FIG. 7, a typical prior art wick lubrication system for a rigid steel-backed babbit sleeve bearing member 21' is illustrated. 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. 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. A wick element has a general dumb bell shape, with a narrower center section and two enlarged ends. Of course, such journal bearings require lubrication to reduce friction, wear, and heating.
