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. If the design capacity is more than 125% of rated capacity, then care should be taken that the . 3. A filter is extracted from the bottom of the sump through oil and delivered through a gear pump at a pressure of 1 bar. The shaft surface speed in this case is 30 rev/sec 5 in. 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. As is best shown in FIGS. 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. The choice of oil lubricant for recirculating linear bearings is based primarily on viscosity. 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). 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. Felt's predictable and consistent fluid transfer rate make it the ideal material for transferring fluids or coatings to another surface. 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.

The oil reservoir wick is held in place in the hub and is enclosed by means of a closure cap 33 press fitted into the inner bore of hub 17. FIG. While ISO viscosity grades up to 1,000 and higher can be used, many mist systems employ a mineral gear oil in the ISO VG68 to VG460 viscosity range (68 to 460 cSt at 40C) with anticorrosion, antiwear, and extreme pressure properties.. Past problems with wax and additive separation from . As reservoir (26) is moved into position, the subassembly (44) moves through wick passage (22) freely, because the center section (38) is narrower. Lubrication is necessary for the proper main-tenance of any machine. In the engine, dippers on the connecting-rod bearing caps enter . passages or nozzles, Arrangements for supplying oil or unspecified lubricant from a stationary reservoir or the equivalent in or on the machine or member to be lubricated, Arrangements for supplying oil or unspecified lubricant from a stationary reservoir or the equivalent in or on the machine or member to be lubricated with feed by capillary action, e.g. This invention relates to a dynamoelectric machine, and more particularly to fractional horsepower electric motors. 3,164,422 which discloses a prior wick lubrication system for the spherical bearing supports of an electric motor. 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. As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. Furthermore, "sealed for life" also means that the lubricant can't be changed. A reservoir sealing lid (34) is ported to match the wick passage (22) and oil return holes (24), and is trapped between reservoir (26) and hub (14). Referring next to FIGS. As a machine, an operating wire rope must also have a lubri- . Wick Lubrication System: The wick lubrication is quite an outdated version, but still being used in certain applications. This drag is translated into extra heat. 1. 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. Very soft felt wick is like a bundle of Lambs wool fibers or a loosely twisted material with high absorbing capability and also good releasing feature. 3. Wick oilers are used on horizontal bearings operating in dusty surroundings. A rotor assembly, as indicated generally at 7, is rotatable within bore 6 in core 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. Oil can be strained, filtered, and cooled because it is . The recommended minimum temperature is typically at least 120F. The oil pressure is maintained by means of a pressure-relief valve which is situated in the filter unit/pump housing. Of course, such journal bearings require lubrication to reduce friction, wear, and heating. Check that the sump tanks are ready for operation. Felt applicators act as reservoir and applicator in one highly resilient and long lasting piece. No. Lubrication also avoids the moving parts not to come in direct contact with each other. 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. 2. Oil may be introduced to the bearing housing in many ways. Owner name: . 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). 5. 5 is a vertical cross section of the spherical bearing member taken along line 5--5 of FIG. Engine influence the efficiency of the choice of the lubricant. Lubrication (Oil) System $ 0.56 - $ 328.16. Is that okay or should I use some special sewing oil wic. 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. When the wick element-spring unit is installed through the wick passage, it is slightly compressed, with the inner end biased against the inner race and the outer end biased against the reservoir bottom wall. 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. 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. Oil is easier to keep clean for recirculating systems. ;ASSIGNOR:LEDERMAN, FREDERICK E.;REEL/FRAME:006174/0385, Free format text: The outer race also includes a trough like sump cut between the ball rows, aligned with the wick passage and oil return holes.
