wick lubrication system

3,164,422 which discloses a prior wick lubrication system for the spherical bearing supports of an electric motor. Gravity Feed i. Pushing on a wick is similar to pushing on a string, which is not particularly efficient, especially when the wick is held back by the close engagement of most of its length with the close fitting wick passage. The one shown in Fig. Check that the shut-off valves at the main pumps are open. No. Wicks are color coded to coordinate wick speeds with application need. Reference may be made to U.S. Pat. The forced, the gravity and the wick feeds are more economical. Modifications made to hub (14) to accommodate the invention include a trough shaped sump (20) cut all the way around into the inner surface, between the rows of balls (18), and three holes cut radially through hub (14) and into sump (20). 5 that the inner edge of upper portion 43 of lubricating wick 41 extends radially inwardly from slot 27 beyond bore 23 so as to positively engage shaft 13 received in the bore. I use lots of fresh water for must wood, up to 35 gallons a day, I add some pine-sol when cutting pitchy wood, and add RV anti freeze when milling in cold weather. Further, it will be noted in FIG. A needle valve adjusts the rate of flow, which may be seen as drops passing through the window beneath the glass reservoir. Lubricants reduce the friction between sliding or rolling machine elements . In the engine, dippers on the connecting-rod bearing caps enter . Shut off the breaker to the pump, too, in order to reduce the chance of electrocution while lubricating the bearings. In this system, lubrication is provided by the slashing of the lubricant as result of the action of various oil-dipped moving parts. Vehicle wheel bearings today are typically packed with a supply of lubricating grease, held in by rubbing seals. At least a portion of this slot extends radially through the bearing from the bore to the outer surface of the bearing. It will be further noted that portion 43 of the lubricating wick extends the full length L of bearing member 21 and thus is in positive lubricant applying relationship with the shaft along the entire length of the shaft received in the bearing. Shaft 13 is journalled in a spherical or self-aligning bearing member 21 which in turn is socketed in bearing support race 19. 3. The wick is a soft, oil absorbent material capable of capillary action. Now rare in four-stroke engines, total loss oiling is still used in many . 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. Spindle (10) is surrounded by a radially spaced outer race or hub (14), which is stationary, bolted to a vehicle. What is mist lubrication system? As shown in FIG. 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. Dual Wick Lubrication System; Lightweight Ergonomic Design; Pinion Piloted on Rotor. A. PATENT EXPIRED DUE TO NONPAYMENT OF MAINTENANCE FEES UNDER 37 CFR 1.362. In FIG. 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. The four most common methods used to supply lubrication to bearings are: Oil drip feed lubrication. Lubrication systems distribute the lubricant to the moving machine parts in contact. Ring lubrication system is generally used for lubrication of: A. Vertical bearings: B. Horizontal bearings: C. Inclined bearings: D. None of these A wick lubrication system for a self-aligning bearing in an electric motor or the like is disclosed. ;ASSIGNOR:LEDERMAN, FREDERICK E.;REEL/FRAME:006174/0385, PATENT EXPIRED DUE TO NONPAYMENT OF MAINTENANCE FEES UNDER 37 CFR 1.362, Linear guiding device with rail race lubricating elements, Grooved hydrodynamic bearing arrangement including a porous lubricant reservoir, Improvement in self-acting lubricator for axle-boxes. 1. 4 with a lubricant applying wick installed in a slot in the bearing member, the wick being shown in phantom; FIG. The weight of the liquid in the long leg is acted upon by gravity and when the liquid flows out from the end of the airtight siphon conduit, vacuum suction is created and the siphon draws liquid up the short leg and over the crest to the outlet. Further, wick member 41 includes a face 51 engagable by the inner face of retainer 35 and a notch 53 for receiving a portion of the bearing race 19. 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. Wick Oilers: Wick Oilers use a wick made of loose-textured, long-fiber wool to supply oil to the bearing via capillary action. 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. 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. 4 is an enlarged cross sectional view taken along line 4--4 of FIG. 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 coil spring (42) has an uncompressed length S that is just slightly greater than C, and a diameter close to the width of wick element center section (38). Oil serves as . As shown in FIG. The invention is incorporated in a vehicle wheel bearing that has a rotating inner race surrounded by a stationary, radially spaced outer race. While the bearing illustrated in FIG. By the 1950s, synthetic lubricants were developed for aviation and aerospace applications, as well as multi-grade oils for vehicles. Each oiler includes a multi-pack of colors for flow testing. Force feed i. 1. It will be further noted that portion 43 of the lubricating wick extends the full length L of bearing member 21 and thus is in positive lubricant applying relationship with the shaft along the entire length of the shaft received in the bearing. 3. 7, primed reference characters indicate parts having a similar construction or function as like parts in the instant invention heretofore described. 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. Lubrication is necessary for the proper main-tenance of any machine. 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. As best shown in FIG. . 7-66.

This grease type, see Fig. A dumb bell-shaped felt piece with a narrower center section and enlarged ends is surrounded by a closely fitting, compressed coil spring that gives rigidity to the felt piece, and which keeps the enlarged ends spread apart . 4, slot 27 has a width, as indicated by dimension W, and a length (shown in FIG. 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 view of the above, it will be seen that the several objects and features of the present invention are achieved and other advantageous results obtained. 1, a dynamoelectric machine (e.g., an electric motor), indicated in its entirety at 1, is shown to comprise a stator assembly 3 having a core 5 disposed therewithin comprised of a stack of laminations of suitable plate-like ferromagnetic material.
