Oil seal effect

The role of large-scale oil seal The role of skeleton oil seal is generally the need to lubricate parts of the transmission components and output components isolated, and will not let the oil leakage, usually used for skeleton oil seal rotary shaft, is a rotating shaft lip seal. The skeleton acts as a reinforcing bar in the concrete element, which keeps the seal in shape and tension. According to the skeleton type can be divided into within the skeleton oil seal, outer skeleton oil seal, inside and outside exposed skeleton oil seal. Skeleton oil seal is made of high quality nitrile rubber and steel plate, stable quality, long service life. Widely used in automobiles, motorcycles crankshaft, camshaft, differential, shock absorbers, engines, axles, front and rear wheels and other parts.

1, to prevent sediment, dust, moisture and other intrusion into the bearings from outside;

2, limiting the oil in the bearing leakage. The requirements of the oil seal is the size (diameter, diameter and thickness) should meet the requirements; require appropriate flexibility, the shaft can properly seize, play a sealing effect; to heat, wear, strength, resistance to media Oil or water, etc.), long service life.

Reasonable use of oil seals, should note the following:

(1) Shaft speed Due to design and structural reasons, high-speed shafts should use high-speed oil seals, low-speed shafts with low-speed oil seals, and low-speed oil seals for high-speed shafts, and vice versa.

(2) ambient temperature In the case of high temperature, should use polypropylene or silicon, fluorine, silicon fluorine rubber. And shall try to reduce the oil temperature in the tank. In the case of the use of low temperature, cold rubber should be used.

(3) the pressure of the general ability to bear the pressure of the oil seal, the pressure is too large will be deformed oil seal. In the use of excessive pressure should be under pressure bearing ring or the use of enhanced pressure oil seal.

(4) eccentricity of the installation The eccentricity of the oil seal and the shaft is too large, the sealing will be worse, especially when the shaft speed is particularly high. If the eccentric is too large, you can use "W" -shaped section of the oil seal.

(5) axis of the surface finish, a direct impact on the life of the seal, the axis of high-quality finish, oil seal life will grow.

(6) Note that the lip in the oil seal should have a certain amount of oil.

(7) to pay special attention to prevent the dust into the oil seal.
