Audited Supplier The role of the skeleton oil seal is generally to isolate the parts of the transmission components that need to be lubricated from the outgoing parts so that the lubricant does not leak, usually for rotating shafts, a rotary shaft lip seal. The skeleton is like the steel reinforcement inside a concrete member, playing a strengthening role and enabling the oil seal to maintain its shape and tension. According to the type of skeleton, it can be divided into internal skeleton oil seal, external skeleton oil seal, internal and external exposed skeleton oil seal. The skeleton oil seal is made of high quality nitrile rubber and steel plate,
with stable quality and long service life. It is widely used in automobile, motorbike crankshaft, camshaft, differential, shock absorber, engine, axle, front and rear wheels, etc.
1,Preventing mud, dust, water vapour, etc. from intruding into the bearings from outside.
2,Limit the leakage of lubricating oil from the bearings. The requirements for oil seals are that the size (inner diameter, outer diameter and thickness) should be in accordance with the regulations; they should have proper elasticity and be able to jam the shaft properly and play a sealing role; they should be heat resistant, wear resistant, good strength, medium resistant (oil or water, etc.) and have a long service life.
To use the oil seal reasonably, the following points should be noted.
(1)The speed of shaft due to design and structure, high speed shaft should use high speed oil seal, low speed shaft use low speed oil seal, can't use low speed oil seal on high speed shaft, and vice versa.
(2) Ambient temperature In the case of high use temperature, polypropylene ester or silicon, fluorine or silicone fluorine rubber should be chosen. And should try to reduce the oil temperature in the oil tank. In the case of using the temperature is too low, should choose to use the cold-resistant rubber.
(3) Pressure General oil seal has poor ability to bear pressure, and the oil seal will be deformed when the pressure is too large. Under the use condition of excessive pressure, pressure resistant support ring or strengthened pressure resistant oil seal should be used.
(4) Eccentricity on installation If the eccentricity of the oil seal and the shaft is too large, the seal will become poor, especially when the shaft speed is high. If the eccentricity is too large, oil seal with "W" shape section can be used.
(5) The surface finish of the shaft directly affects the service life of the oil seal, i.e. if the shaft finish is high, the service life of the oil seal will be long.
(6)Note that there should be a certain amount of lubricating oil at the lip of the oil seal.
(7) Pay special attention to prevent dust from dipping into the oil seal.
