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). Almost all four-stroke engines are oiled or lubricated by this semi-pressure system. 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. 6-29), oil is splashed up from the oil pan or oil trays in the lower part of the crankcase. Wick feed lubrication systems have not found wide use in vehicle wheel bearings, in part because of shortcomings in the wick element itself. 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'. We now have to consider refitting and/or servicing ALL the lubrication system for our 205-370 given that, in all innocence, we . 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. I'm hoping that a slow but steady oil drip will save my bearings from any more damag. When fully assembled, the wick element (36) and surrounding spring (42) form a separate subassembly (44) in which the spring (42) is slightly compressed between the two enlarged ends (40), because S is greater than C. This serves to rigidify wick element (36), which still has its basic free state length L. Spring (42) has an additional function, described next. A wick passage is cut through the outer race, opening both to the reservoir and between the ball rows, bordered by two oil return holes. Oil may be introduced to the bearing housing in many ways. 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'. Drip Feed Lubricator iv. It is also known as the Ring Oiling system. Such a twist lock retainer is more fully disclosed in the coassigned U.S. patent, now U.S. Pat. Oil is easier to keep clean for recirculating systems. Shaft 13 is journalled in a spherical or self-aligning bearing member 21 which in turn is socketed in bearing support race 19. This is best illustrated in FIG. 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. This is best illustrated in FIG. 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.

Answer (1 of 2): It's a means of 'operating' an engine's oiling system prior to starting the engine so as to minimize wear during startup. 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. 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. 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. 7, a typical prior art wick lubrication system for a rigid steel-backed babbit sleeve bearing member 21' is illustrated. 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. When installed, the wick element and supporting spring are . Wick Lubricator iii. 1. They 'float' on a thin film of oil that is forced under pressure into . 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. 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. 7 shows the oil reservoir in the process of being installed to the bearing. Further, it will be noted in 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 41 is shown to have a second end portion 45 opposite the above-mentioned shaft engaging portion 43 with an intermediate portion 47 connecting portions 43 and 45. 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. 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. 4, slot 27 has a width, as indicated by dimension W, and a length (shown in FIG.
