Installation of skeleton oil seals:
One side of the spring is in the middle (for oil) and the other side, with the word specification, is out。
1 the skeleton seal is a typical representation of the oil seal, which is generally referred to as the skeleton seal. The role of the shelving is generally to isolate the lubricating parts from the active components of the moving parts so that the lubricant does not leak. The skeleton, like the steel inside the concrete building blocks, acts as a reinforcement and keeps the oil seal in shape and tension. In structural form, it is possible to divide the oil envelopes of the sole and the double-lipbrand。
2. The sub-lipps of the tarcrete of the lip skeleton act as dustproofs to prevent external dust, impurities, etc. From entering the machine. It can be divided into internal skeleton oil seals, exterior skeleton oil seals and assembly seals according to the skeleton type. In accordance with working conditions, it can be divided into rotating skeleton oil seals and round-trip skeleton seals. For petrol engine curvatures, diesel engine curvatures, gear transformers, speed differentials, shock-mitigators, engines, bridges, etc。
Delineation of the skeleton oil seal:
(b) effects: the role of the skeleton oil seal is generally to isolate the lubricating parts from the active parts of the moving parts, so that the lubricating oil does not leak, usually for the rotation axis, and is a rotating axle lip seal. The skeleton, like the steel inside the concrete building blocks, acts as a reinforcement and keeps the oil seal in shape and tension. It can be divided into internal, external and external. The skeleton oil seals are made of high-quality blubber rubber and steel plates of stable quality and long operational life. Widely used in cars, motorcycle rotors, cam axes, speed differentials, tremors, engines, bridges, back and back wheels, etc。
Reasonable use of the oil seal should be noted as follows:
(1) for design and structural reasons, high-turned axes shall use high-speed oil seals, low-turned axes shall use low-speed oil seals and cannot be used on high-speed axes or vice versa。
2) at higher ambient temperatures, polypropylene or silicon, fluorine, silicon fluorine rubber should be selected. Efforts should also be made to reduce the temperature of oil in tanks. Where the temperature is too low, cold-resistant rubber should be selected。
(3) the pressure-like oil seal is less capable of being pressure-ridden and, when over-pressure, it is deformed. Pressure-resistant bearings or enhanced pressure-resistant oil seals should be used under excessive pressure conditions。
(4) installation of diagnosing oil seals and axial co-operations which are excessively eccentric, and whose sealing properties deteriorate, especially when the axial speed is high. If the bias is too large, the oil envelope of the “w” fracture may be used。
(5) the surface purity of the axis directly affects the useful life of the oil sheath, i. E., the high light purity of the axis, which results in a longer life of the shear。
(6) pay attention to a certain amount of lubrication in the mouth of the oil seal. Oil
Part of the mechanical friction was caused by the presence of oil during the operation of the machinery, which was used to prevent the leakage of the oil from the mechanical gap. In addition to oil, there is a need to prevent the leakage of water and chemical fluids and the intrusion of dust and sand from outside, when oil seals are also used。
The skeletal seal is a typical representation of the skeletal seal, which is generally referred to as the skeletal seal. The role of the shelving is generally to isolate the lubricating parts from the active components of the moving parts so that the lubricant does not leak. Its structure may include: metal skeletons, rubber parts (also divided into lips and co-operations), springs. Different forms of oil seals may be selected depending on the conditions。
