What is automobile oil seals

Continuous development with the ages, advances in technology.

Technology has brought great convenience and speed to people's lives, and automobiles have become an indispensable "life item" in modern people's lives, and have also given little room for development in the related auto parts industry. Due to the many brands and models of automobiles, take the oil seals used in automobiles as an example, the shape of the oil seals will vary with the model and brand of the car, but they are generally similar. If the user does not know the oil seal improper performance or storage and installation operations can easily cause oil seal leakage. Automobile oil seals are generally composed of the following parts:

Rubber: The main body of the oil seal, which uses the high elasticity of the seal material to achieve a sealing effect;

Metal skeleton: Because it is a rigid body, the structural rigidity of the oil seal is increased, and it can play a static sealing role in specified occasions and environments;

Spring: Provide radial force to the oil seal to ensure sealing

The role played by the various parts of the rubber elastomer in the automobile oil seal:

1. The rubber sealing lip of the automobile oil seal: it is a flexible elastomer, designed to maintain a stable sealing effect under the influence of mechanical vibration and pressure changes of the sealing fluid, and to maintain stable contact between the lip and the shaft surface The role of state.

2. The dust-proof lip of the rubber of the automobile oil seal: it is a secondary lip that is not connected to the spring, which prevents the intrusion of dust and so on.

3. The mating part of the rubber of the automobile oil seal: it is the part of the oil seal that is fixed in the cavity, and plays the role of fixing the oil seal in the cavity and preventing fluid leakage from the outer peripheral surface of the oil seal and the contact surface in the cavity.
