Oil Seal Simple And Easy To Manufacture

Oil seal, also known as a shaft seal, is a device part used in a machine to prevent fluid (mostly lubricating oil) from overflowing the joint (mostly the joint or shaft of the part). Static seal and dynamic seal (general reciprocating motion) with seals called seals. Oil seal on behalf of the form is TC oil seal, which is a completely covered with rubber from the tight spring spring lip seal, the oil seal is generally said that this tc skeleton oil seal.

Oil commonly used materials are: nitrile rubber, fluorine rubber, silicone rubber, acrylic rubber, polyurethane, polytetrafluoroethylene and so on. When selecting the oil seal material, the compatibility of the material with respect to the working medium, the adaptability to the operating temperature range, and the ability of the lip to rotate at high speed for the rotary axis must be taken into account. General oil seal work when the lip temperature is higher than the working medium temperature 20 ~ 50 ℃, in the choice of oil seal material should be noted. For details, please refer to: Rubber types and characteristics. The working range of the oil seal is related to the material used for the oil seal: the material is -40 to 120 ° C for the nitrile rubber (NBR), the rubber of the rubber (ACM) -30 to 180 ° C, and the fluororubber (FPM) -25 to 300 ° C.

Functional use

Engine: crankshaft - crankshaft front and rear oil seal valve - valve oil seal (engine repair kit o-ring) (distributor oil seal, pump oil seal, balance shaft oil seal, oil pump seal ...); camshaft - camshaft oil seal ; Transmission: transmission - transmission before and after the oil seal shift lever oil seal (transmission repair package o-ring) (splitter - before and after the oil splitter); rear axle: axle - rear axle oil seal difference (Front axle oil seal).

Any oil tank that has liquid lubricating oil and which is connected to the outside is required. Some are rubber, some are metal, mostly steel rubber, such as crankshaft after the oil seal, gearbox before and after the oil seal, left and right axle oil seal, the main reducer before the oil seal, air compressor crankshaft oil seal.

Advantages

1, oil seal structure is simple, easy to manufacture. Simple oil seal can be molded once, even the most complex oil seal, the manufacturing process is not complicated. Metal skeleton oil seal only through the stamping, gluing, mosaic, molding and other processes can be composed of metal and rubber seals required.

2, oil seal light weight, less supplies. Each oil seal is a combination of thin-walled metal parts and rubber parts, the material consumption is very small, so the weight of each oil seal is very light.

3, the oil seal installation location is small, small axial size, easy processing, and make the machine compact.

4, oil seal the sealing function is good, long service life. The vibration of the machine and the eccentricity of the spindle has a certain degree of adaptability.

5, oil seal demolition easy, easy to test.

6, oil seal cheap.
