Step 3: Locate Lubrication Ports. Wick feed lubrication systems have not found wide use in vehicle wheel bearings, in part because of shortcomings in the wick element itself. Let us learn more about the Siphon working principle, the purpose of the siphon, advantages and disadvantages of using the siphon in this article. Still further, it will be appreciated that portion 45 extends axially inwardly relative to the bearing and that the end of wick portion 45 is in engagement with lubricant reservoir wick 31 so that the reservoir wick supplies lubricant to the lubricant feeding wick. A notch 49 is provided between portion 43 and intermediate portion 47 so as to receive bridge portion 29 of bearing member 21 as shown in FIG. Reference may be made to U.S. Pat. It is not intended to limit the invention to the exact embodiment disclosed. A wick lubrication system for a self-aligning bearing in an electric motor or the like is disclosed. Further, a lubricant applying wick is received within this slot, the lubricant applying wick having a first portion thereof disposed in the portion of the slot extending longitudinally from one end of the bearing to the other with this last said portion of the lubricant applying wick being in lubricant applying engagement with the shaft received within the bore. 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. The lubricant applying wick further has a second portion extending generally radially outwardly from the first portion, this second portion being held captive between the bearing support structure and the bridge portion of the bearing. 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. Flow rate depends on temperature.. Use 90 elbow cups for side-mount applications and where vertical space is limited.. Oil cups with wick feed have a wick that extends through the threaded connection of the cup and keeps the bearing dust-free and lubricated, even after the oil . Drip Feed Lubricator iv. Oil Mist Lubrication Working Principle. No. Turbine lubrication: Practical guidelines. Oftentimes, as shown in FIG. by wicks, GENERAL MOTORS CORPORATION, A CORP. OF DE, MICHIGA, ASSIGNMENT OF ASSIGNORS INTEREST. 2; FIG. Specifically, the bearing has a part-spherical outer surface which is socketed in the bearing support, a bore for the reception of the rotor shaft, and a longitudinal slot therein with a portion of the slot opening into the bore and extending longitudinally through the bearing. As a consequence, it is soft, with little internal rigidity. 276. 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'. 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 wick lubrication system for a self-aligning bearing in an electric motor or the like is disclosed. Check that the oil temperature is high enough. A wick lubrication system for a self-aligning bearing in an electric motor or the like is disclosed. 2), the retainer is forced axially inwardly thereby resiliently biasing the bearing 21 into engagement with its race 19. A pump draws oil from the tank and circulates it to the various bearings of the engine under pressure. Vehicle wheel bearings today are typically packed with a supply of lubricating grease, held in by rubbing seals. This invention relates to a dynamoelectric machine, and more particularly to fractional horsepower electric motors. 7-66. 5, wick portion 43 also extends the length of bearing member 21. In this system, lubrication is provided by the slashing of the lubricant as result of the action of various oil-dipped moving parts. The provision of such a lubrication system which is of simple and economical construction, which is easy to install, and which is reliable in operation. It is a more technically advanced and usually more costly method, but it results in longer life for a compressor. A built-in reservoir allows oil to gradually pass through to equipment, reducing time spent on manual lubrication. Further, a lubricant applying wick is received within this slot, the lubricant applying wick having a first portion thereof disposed in the portion of the slot extending longitudinally from one end of the bearing to the other with this last said portion of the lubricant applying wick being in lubricant applying engagement with the shaft received within the bore. 2. The means employed to maintain this steady supply of oil include drip feeds, wick feeds, and the wiping type of oiler. ;ASSIGNOR:LEDERMAN, FREDERICK E.;REEL/FRAME:006174/0385, Free format text: The main supply of oil in this system is located in the base of the crank chamber. a) Mist lubrication system. Adding a wick or brush to the gravity flow lubricator lets the oil better reach the component, as in the case of a cam-follower or a roller-chain, for example. 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. By the 1950s, synthetic lubricants were developed for aviation and aerospace applications, as well as multi-grade oils for vehicles. 1. Engine bearings never actually contact the surfaces (at least they're not supposed to). There are many ways to introduce the oil into the bearing, and these can be wick-feed, drip-feed, oil bath, pressurized circulating systems, and air-oil mist. PATENTED CASE. Further, it will be noted in FIG. Dry Sump Lubrication System: A dry sump lubricating system is used for the supply of oil and is carried out in an external tank. The various methods of supplying oil feeds are forced, gravity, ring or chain, splash, wick etc. The wick is a soft, oil absorbent material capable of capillary action. 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.

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. 3 is a vertical cross sectional view taken along line 3--3 of FIG. Oftentimes, as shown in 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 . Pressure Feed by Hand Pump iii. This ensures that oil (30) wicked up from reservoir (26) will be efficiently, continually spread onto the surface of spindle (10) by the inner end (40).

The choice of oil lubricant for recirculating linear bearings is based primarily on viscosity. . Each oiler includes a multi-pack of colors for flow testing. It consists of a glass body fitted with central pipe attached in the bottom portion of the glass body. 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. 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. Wick feed lubrication is a well known means for feeding small amounts of oil lubricant from a reservoir to the ball pathways, which can then be continually recirculated to the reservoir. 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. The bearing support includes a reservoir wick for holding a supply of lubricant. Typically, the motor includes a rotor shaft, a bearing support and a self-aligning bearing supported thereby journalling the rotor shaft of the motor. 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.
