Mar 25, 2022
With the continuous development of the times, the progress of science and technology. Technology has brought great convenience and speed to people's lives, and automobiles have become an indispensable "daily necessities" in modern people's lives, which also allows the related auto parts industry to have room for development. Since there are many brands and models of automobiles, taking the oil seal for automobiles as an example, the shape of the oil seal will vary with the model and brand of the car, but it is generally similar. If the user does not understand the performance of the oil seal or the storage and installation operations Improper, it is easy to cause oil seal leakage. Automobile oil seals are generally composed of the following parts.
Rubber: The main body of the oil seal uses the high elasticity of the seal material to achieve a sealing effect;
Metal skeleton: Because it is a rigid body, it increases the structural rigidity of the oil seal, and can play a static sealing role in specified occasions and environments；
Spring: Provides radial force to the oil seal to ensure sealing.
The role of each part of the rubber elastomer in the automobile oil seal:
1. The sealing lip of the rubber 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 fluctuations of the sealing fluid, and to maintain stable contact between the lip and the shaft surface role of status.
2. The rubber dust-proof lip of the automobile oil seal: it is the auxiliary lip that is not connected with the spring, and plays the role of preventing the intrusion of dust and the like.
3. The rubber mating part of the automobile oil seal: it is the part of the oil seal fixed in the cavity, which plays the role of fixing the oil seal in the cavity and preventing the leakage of the contact surface between the outer peripheral surface of the oil seal and the cavity in the fluid.
