Function and rational use of automobile oil seal

Automobile oil seal is a mechanical component used to seal grease (oil is a common liquid substance in the transmission system, also generally refers to the meaning of general liquid substance). It isolates the parts that need lubrication in the transmission parts from the output parts, so as not to let the lubricating oil leak. What are the functions of automobile oil seal? 1、 As the name suggests, oil seal is a mechanical component used to seal oil. It isolates the parts that need lubrication in the transmission parts from the output parts, so as not to let the lubricating oil leak. The seals used for static seal and dynamic seal (generally reciprocating motion) are called seals. The representative form of oil seal is TC oil seal, which is a double lip oil seal with self tightening spring completely covered by rubber. Generally speaking, oil seal often refers to this TC skeleton oil seal. 2、 Purpose and position of oil seal: 1. Engine: crankshaft - crankshaft front and rear oil seals; 2. Valve - valve oil seal (O-ring of engine repair kit) (distributor oil seal, water pump oil seal, balance shaft oil seal, oil pump oil seal, etc.); 3. Camshaft - camshaft oil seal; 4. Transmission: transmission - front and rear oil seals of transmission; 5. Shift lever oil seal (O-ring of transmission repair kit) (transfer case - front and rear oil seals of transfer case); 6. Rear axle: front axle shaft and rear axle shaft oil seal 7. Differential: (front) rear angle oil seal, rear wheel oil seal, front wheel oil seal; 8. Steering gear oil seal (steering gear repair kit O-ring) steering booster oil seal (front axle shaft oil seal). 3、 All parts with liquid lubricating oil in the running body box and connected with the outside need oil seal. Some are rubber, some are metal, and most are steel reinforced rubber, such as crankshaft rear oil seal, gearbox front and rear oil seal, left and right axle oil seal, main reducer front oil seal, air compressor crankshaft oil seal, etc

What are the factors affecting the effect of oil seal?

Skeleton oil seal is a typical representative of oil seal. Generally speaking, oil seal refers to skeleton oil seal. The effect of oil seal is generally to block the parts requiring lubrication in the transmission parts from the output parts, so as not to let the lubricating oil leak. ① The specification and model of split skeleton oil seal are not suitable. The specification of split skeleton oil seal is basically the same as that of ordinary skeleton oil seal. When choosing to use, pay attention to whether the specification and model meet the requirements. Too large or too small specification will not only reduce the service life of split skeleton oil seal, but also lead to equipment oil leakage and other accidents. ② The quality of split skeleton oil seal is unqualified. Pay attention to the quality of split skeleton oil seal. The sealing performance and service life of unqualified oil seal will be reduced. The service life of oil seal with guaranteed quality will not be affected. ③ The sealing effect of split skeleton oil seal is not ideal. According to practical application, split skeleton oil seal can be divided into various material oil seals, and its service conditions are also different. If the selection is improper, the predetermined sealing effect and service life cannot be achieved. There are many factors affecting the service life of split skeleton oil seal. Pay attention to the actual working conditions when selecting and using, and select high-quality oil seal with appropriate specifications and models to ensure that its service life is not affected.

How to install the hydraulic seal ring

The method of correctly installing the hydraulic seal ring is as follows: 1. Check the relevant surfaces of piston, cylinder barrel and installation guide sleeve to ensure they are clean, free of burrs and edges. 2. The installation tools shall be smooth without edges and sharp corners to ensure that the seals will not be damaged in any form during installation. 3. During installation, a small amount of grease can be painted on the relevant surfaces of the seal and cylinder barrel to facilitate installation, but residual grease is not allowed between the rubber elastomer and the sliding sealing ring, otherwise the sealing performance will be affected. 4. Whether it is vertical or horizontal installation, the coaxiality of piston and cylinder barrel shall be maintained. Excessive eccentricity is likely to damage the seal. 5. The installation speed should not be too fast, otherwise the seal will be damaged.
