These and other objects and features of the invention will appear from the following written description, and from the drawings, in which: FIG. As a consequence, it is soft, with little internal rigidity. Another type of lubrication system is the splash lubrication system. 6 is a side elevational view of the lubricant applying wick; and. Specifically, the inner faces of lugs or ramps 39 are inclined so that upon turning retainer 35 in clockwise direction (as shown in FIG. Referring next to FIGS. Oil-mist lubricating systems should operate at pressures of ___ psi. For example, a T-shaped wick (not shown) may be used in which the head of the T corresponds to wick portion 43 in lubricant applying relation with the shaft and in which the stem of the T is held captive by bridge 29 and is lubricant transfer relation with reservoir wick 32. 6). Referring next to FIGS. As the elevator operates, the hoist ropes are cleaned. Such a twist lock retainer is more fully disclosed in the coassigned U.S. patent, now U.S. Pat. Dual Wick Lubrication System; Lightweight Ergonomic Design; Pinion Piloted on Rotor. 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. 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. Lieuvain's Glass Bottle Lubricator 2. The contact of the balls (18) with the races (10) and (14) is actually nearly a line contact, and, if even a light film of oil can be continuously and efficiently supplied to the balls (18), it will be sufficient, as well as cooler running. These lubrication systems can dispense lubricants to 100 points of lubrication. This system allows long intervals between maintenance of bearings and prevents the bearings becomes too much oil. 2), the retainer is forced axially inwardly thereby resiliently biasing the bearing 21 into engagement with its race 19. Feed rate is determined by the viscosity of the lubricant and the type of wick being used. This drag is translated into extra heat. Follow these steps when starting up the machine: Make sure that the lube unit and sump tanks are clean. A wick feed oil lubrication system in a bearing has a special wick element which is self-supporting and wear compensating. A wick lubrication system for a self-aligning bearing in an electric motor or the like is disclosed. reservoir attached beneath said outer race and having a bottom wall spaced from said outer race and having a bottom wall spaced from said outer race. The core has a bore 6 extending longitudinally therethrough. Oftentimes, as shown in FIG. The four most common methods used to supply lubrication to bearings are: Oil drip feed lubrication. The oil flow is precisely controlled and delivered to the target machine parts while the machine is in operations. 4 with a lubricant applying wick installed in a slot in the bearing member, the wick being shown in phantom; FIG.

When installed, the wick element and supporting spring are . ;ASSIGNOR:LEDERMAN, FREDERICK E.;REEL/FRAME:006174/0385, Free format text: 2, the twist lock retainer has tabs 38 at its corners which cooperate with lugs 39 formed in hub 17. Each oiler includes a multi-pack of colors for flow testing. 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. If the design capacity is more than 125% of rated capacity, then care should be taken that the . Check that the oil temperature is high enough. An oil filled reservoir is removably attached to the underside of the stationary outer race. Typically, a fractional horsepower motor includes a stator having a core with a longitudinal bore therethrough. Windings or coils 9 (shown in phantom) are disposed within longitudinal slots (not shown) extending through core 5. Pressure lubrication is a process where an oil pump precisely distributes oil to key areas of the pump. 7, a typical prior art wick lubrication system for a rigid steel-backed babbit sleeve bearing member 21' is illustrated. Step 1: Cut wicking cord (six to eight sections, each 15 to 20 inches long). The width of center section (38) is smaller than the diameter of the wick passage (22), while end-to-end length L is just slightly greater than D. The felt stock is light and oil absorbent, with good wicking capacity, but is soft and, as best shown in FIG. This helps administer the right amount and keep the gear oil on the metal gears. Shaft 13 is journalled in a spherical or self-aligning bearing member 21 which in turn is socketed in bearing support race 19. Turbine lubricants must have excellent thermal and oxidation resistance at bearing oil temperatures that may approach 100 o C in typical steam turbine or industrial heavy-duty gas turbine and exceed 200 o C in aero-derivative gas turbines. 4, slot 27 has a width, as indicated by dimension W, and a length (shown in FIG. Which type of lubrication system is used in two-stroke engine? Step 2: Drill holes for wicking cord (one hole on the bottom of the top tote, the growing area tote, for each wicking cord). Lubrication is necessary for the proper main-tenance of any machine. 4. Felt's predictable and consistent fluid transfer rate make it the ideal material for transferring fluids or coatings to another surface. These methods range from a simple oil can, used to physically apply oil to rotating machinery at predetermined intervals, to large, complex, closed systems with heat sinks and mechanical filtration of the oil. As shown in FIG. Turn off the circulating pump. 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. 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). Designed to lubricate individual machines or complete plants, automatic lubrication systems provide proper, precise lubricant replenishment to all required points, enabling a range of benefits in the process. 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 it rigidity, and which keeps the enlarged ends spread apart. 1. 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. 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'. . Benefits. Typically, the motor includes a rotor shaft, a bearing support and a self-aligning bearing supported thereby journalling the rotor shaft of the motor. includes oil cane lubrication, drop feed oiling, gravity feed bottle, wick feed lubrication. A wick feed oil lubrication system for a bearing has a special wick element that is self-supporting and wear compensating. 5, wick portion 43 also extends the length of bearing member 21. 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. 6 is a side elevational view of the lubricant applying wick; and. 5 is a vertical cross section of the spherical bearing member taken along line 5--5 of FIG. . 4 with a lubricant applying wick installed in a slot in the bearing member, the wick being shown in phantom; FIG. 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. done. 3 is a vertical cross sectional view taken along line 3--3 of FIG. 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. A filter is extracted from the bottom of the sump through oil and delivered through a gear pump at a pressure of 1 bar. Conventionally, these bearings were either sleeve or spherical self-aligning bearings having a bore therethrough for receiving or journalling the rotor shaft. A total-loss oiling system is an engine lubrication system whereby oil is introduced into the engine, and then either burned or ejected overboard. 3 is a vertical cross sectional view taken along line 3--3 of FIG. 1. 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. 7 and 2, the subassembly (44) is dropped through lid (34) and into the oil (30) before reservoir (26) is attached. 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. Standards CE Certified; EAC Certified. 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 it rigidity, and which keeps the enlarged ends spread apart. UNSPSC 27131511. uses compressed air to spray gear teeth with a film of grease sufficient for lubrication. Wick oilers are used in applications where precise oiling is required. Check the pressure level in a lubrication system: Step 1. 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. The oil pressure ranges from 100 to 250 psi. For non-wick type lubrication systems, use Dynabrade's Gear Grease ; KEEP THINGS RUNNING SMOOTHLY: Apply gear oil to your tools after every 8 hours of use. Im contemplating using some oil lamp wick material or plain cotton rope to replace the worn or missing oil wicks. 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). 7-66. No. 6-29), oil is splashed up from the oil pan or oil trays in the lower part of the crankcase. 5), as indicated by dimension L. In FIG. 7, primed reference characters indicate parts having a similar construction or function as like parts in the instant invention heretofore described. 276. Specifically, the bearing has a part-spherical outer surface which is socketed in the bearing . 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 forced, the gravity and the wick feeds are more economical. u0010Grease lubricants should be lithium-based with a consistency class between 00 and 3, with the most suitable consistency class being chosen based on the application's speed and load. 3. insulating supports or means for fitting bearings in the bearing-shields using sliding-contact or spherical cap bearings radially supporting the rotary shaft at both ends of the rotor. 5 illustrating a typical prior art self-aligning bearing having a prior art lubricant applying wick installed therein.

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. Wick Lubricator iii. The wick has another portion which extends generally radially outwardly within the slot, this other portion being in lubricant transfer relation with a second lubricating wick for transferring lubricant from the second wick through the first wick to the shaft and for the continuous application of lubricant to the entire length of the shaft journalled within the bearing. Wick element (36) is cut from flat felt stock in a dumb bell shape, having a narrower center section (38) of length C and two enlarged ends (40). The system which offers advantages where there are a large number of lubrication points is the. Ring lubrication system is generally used for lubrication of: A. Vertical bearings: B. Horizontal bearings: C. Inclined bearings: D. None of these 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. 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. Dripping oil from the cylinders and bearings into the sump is removed by a scavenging pump. As shown in FIG. Drip Feed Lubricator iv. 6). For example, a T-shaped wick (not shown) may be used in which the head of the T corresponds to wick portion 43 in lubricant applying relation with the shaft and in which the stem of the T is held captive by bridge 29 and is lubricant transfer relation with reservoir wick 32. Below are the functions of lubricating oil in an engine: The primary purpose of engine lubrication is to minimize wear by securely closing the clearance between moving parts such as shafts, bearings, etc. It is a more technically advanced and usually more costly method, but it results in longer life for a compressor. , drop feed oiling, gravity feed Bottle, wick portion 43 also extends length!
