Abstract
The invented equipment is mainly used in the lubrication of head sheave in the lifting system of slope rail series connected vehicles and is characterized by that two sides of wheel hub are opened with arc shaped oil guiding channel, one end of the channel has oil outlet hole connected with the oil cavity of wheel hub, and the other end has an oil feeding hole connected with oil channel on the inner surface of axle sleeve. It can ensure automatic lubrication of head sheave during slow rotation by the gravitational force of lubricating oil.
Description
The invention belongs to the sliding bearing lubricating technical field, relate to a kind of head sheave of moving about, upper saw pulley oil lubrication that studs with axle sleeve.
The upper saw pulley that the slope polyphone promotes (or the slope orbit mine car promotes) usefulness is installed on the derrick, both rotates, again along moving axially, so be called the head sheave of moving about.Stud with axle sleeve in the head sheave of the moving about wheel body axis hole, make cavity between axle sleeve and wheel hub, fill lubricant oil, oil flows into fastness by the oil hole on the axle sleeve and is lubricated (see figure 1).In actual use, store incessantly lubricant oil in the oil pocket, oil ran off soon through oil hole when main because wheel body rotated, thus generally be per tour by artificial toward spool on directly water oil and not oiling in the oil pocket, both wasted a large amount of lubricant oil, also polluted environment.The head sheave of moving about is installed on the outdoor derrick, running check is refueled very inconvenient, dangerous again, therefore usually be under the oil starvation state, to move, moreover it is again running, a discontinuous operation under lower-speed state, promptly start continually and parking, because insufficient lubrication, startup and surface friction drag in service are bigger, this has not only increased power consumption, has also quickened the wearing and tearing of axle with axle sleeve, also makes the grooving and the boom hoist cable wearing and tearing aggravation of wheel body, influence the working life of head sheave and wire rope, and give to administer and maintain and brought difficulty.People want to address this problem always for many years, and are all undesirable.The head sheave of moving about that Fig. 2 uses for Dongchuan Luo Xuekuang adopts wick formula glass oil cup lubricated, lubricating cup is fixed on the slip ring that flexibly connects with wheel hub one end, add counterweight on the suspension rod of bottom, slip ring only moves axially with wheel body when making the head sheave operation, though the oiling continuously of this device, still oiling when head sheave is out of service has caused waste and environmental pollution, axially move difficulty in the use, reliable inadequately.
The objective of the invention is to propose a kind of on-stream automatic oiling and lubricated device of carrying out according to actual needs of the head sheave of moving about (or upper saw pulley) that studs with axle sleeve.
The present invention has garden arc oil guide slot on the wheel hub both ends of the surface of wheel body, the two ends of groove have oil outlet and oil hole and communicate with oil duct on oil pocket and the axle sleeve internal surface in the wheel hub respectively, from the same end of wheel hub, the oil outlet at two ends is opposite to the rotation direction of oil hole.Lubricant oil is not filled with in the annular oil cavity, to guarantee no matter which kind of position wheel body stops to, lubricant oil all can not flow out through oil hole from oil pocket, and wheel body is when rotating, wherein one bring out oilhole and forward to below the oil pocket liquid level, oil flows into oil guide slot through oil outlet, be rotated further, the oily oil guide slot of flowing through under action of gravity, oil hole inject the axle sleeve internal surface and are lubricated, the other end is because oil outlet arrives the rotation direction and the then not oiling of wheel body direction of rotation of oil hole, should hold oiling during counter-rotating, the big I of oil filling amount is controlled by the fuel-economizing bolt.
Advantage of the present invention is:
(1), oiling during the wheel body slow rotation, promptly mainly be to start and oiling during braking, rotate stop after not oiling, the oil filling amount size can be regulated, and has both guaranteed normal lubricatedly, has saved a large amount of lubricant oil again, has reduced the pollution to environment.
(2), simple in structure, do not need special equipment and device just can realize equipment operation the time automatic oiling lubricate.
(3), reduced labor intensity, saved manpower, be convenient to maintenance and management.
(4), prolonged the working life of axle sleeve, wheel body and wire rope.
Fig. 3, Fig. 4 have drawn structural representation of the present invention, automatic oiling lubrication principle figure.
Stud with axle sleeve 2 in the endoporus of wheel body 1, oil pocket 11 is used to store lubricant oil in the wheel hub, for anti-oil leak, add O type seal 5 between the matching surface of axle sleeve and wheel hub, the wheel hub both ends of the surface have the garden arc oil guide slot 10 of diameter near the oil pocket external diameter, heart angle, the pairing garden of oil guide slot 〉=270 °, one end of groove has oil outlet 6 and communicates with oil pocket 11, the other end has oil hole 9 and links to each other with oil duct on axle sleeve 2 internal surfaces, the oil outlet at wheel hub two ends is opposite to the rotation direction of oil hole through oil guide slot, tighting a bolt compresses end gland 3 and sealing gasket 4, in case leakage of oil.On the axle sleeve internal surface, have the spirality oil duct between oil hole, oil hole to two ends have straight shape oil duct 8.Lubricant oil is not filled with in the oil pocket, guarantee which kind of position no matter wheel body go to, oil guide slot internal diameter the topmost part a bit exceeds liquid level 10mm at least, makes wheel body when out of service, and oil can not continue to flow out from oil hole, and move about head sheave when slow rotation, lubricant oil from the oil outlet outflow of wheel hub one end, injects fastness through oil guide slot, oil hole under action of gravity, wheel hub the other end oil hole oiling (see figure 4) during counter-rotating is regulated fuel-economizing bolt 7 may command oil filling amount sizes.It is lubricated that the present invention is used for the head sheave of moving about of slope tube-train hoisting, satisfied the service condition of the head sheave of moving about, the normal operation of the head sheave of having guaranteed to move about.
Claims (1)
- A kind of head sheave of moving about of inlaying axle sleeve, upper saw pulley automatic oiling and lubricating fitting, the present invention is characterised in that and has the garden arc oil guide slot of diameter near the oil pocket external diameter on the wheel hub both ends of the surface, heart angle, the pairing garden of oil guide slot is more than or equal to 270 °, one end of groove has oil outlet to communicate with oil pocket in the wheel hub, the other end has radially oblique oil hole link to each other with oil duct on the axle sleeve internal surface, the wheel hub two ends are opposite to the rotation direction of oil hole through oil guide slot by oil outlet, adopt bolt that the oil guide slot gland is compressed, lubricant oil is not full of in the oil pocket, make wheel body when slow rotation, lubricant oil is from wherein one bringing out the oilhole oil guide slot of flowing through in the oil pocket, oil hole injects the axle sleeve internal surface and is lubricated, installing fuel-economizing bolt on oil outlet, adjusting oil mass size, axle sleeve and wheel hub cooperation place are equipped with the leakage that the O RunddichtringO prevents oil.
