Circulating systems . Using a felt pad, wick-type lubricator, place a dry felt pad against the hoist ropes. The most common systems are: 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. Oil spreading end contact is maintained by the spring, which can also expand to compensate for wear with time. Wick Feed Lubrication System - China Manufacturers, Factory, Suppliers. Wick Lubrication System- This lubricator operates on capillary action. 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'. From there, as shown by the arrows in FIG. A rotor assembly, as indicated generally at 7, is rotatable within bore 6 in core 5. 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. 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 . Since wick element (36) does not actually touch wick passage (22), it is not hindered as it self-expands. To work properly, the inner end of the wick has to be kept in rubbing . The forced, the gravity and the wick feeds are more economical. Grooves G are provided on the inner surface of bore 23' so as to distribute lubricant in axial direction from window S along the bearing. Functions of Engine Lubricating System. 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. 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. 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. Oil and bearings. 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. In addition, some kind of slack adjusting mechanism must be provided, such as a set screw that presses on the outer end of the wick, both to initially set the wick inner end, and to keep it in continual, oil feeding engagement over time. Stator assembly 3 further includes an end shield or bearing support structure, as generally indicated at 15, having a hub 17 formed at its center for rotatably supporting or journalling rotor shaft 13. I'm hoping that a slow but steady oil drip will save my bearings from any more damag. Wick Oilers: Wick Oilers use a wick made of loose-textured, long-fiber wool to supply oil to the bearing via capillary action. 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. 1; 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.
