Rubber

Rubber in excavators is primarily used for sealing, vibration dampening, wear resistance, and protection.

The application of rubber in excavators is reflected in several key areas:

1. Sealing Function: Rubber materials are used to create sealing components, such as O-rings and lip seals, which are employed for both static and dynamic sealing. These sealing elements provide excellent sealing performance within certain working pressure and temperature ranges, effectively preventing fluid leakage. They also feature a low coefficient of friction and stable friction force, which helps avoid issues like component creep and jamming. Additionally, these seals possess good wear resistance, oil resistance, and corrosion resistance, allowing them to automatically compensate for wear and geometric precision errors to some extent.

2. Vibration Dampening: Excavators utilize high-performance rubber vibration dampers, such as SW rubber dampers, which are primarily designed to suppress extreme shocks, low-frequency vibrations, and machine noise. These dampers are developed with specialized rubber formulations that significantly absorb heat generated by vibrations, making them suitable for heavy equipment such as pile drivers and rollers, effectively reducing vibrations and noise during operation.

3.Wear Resistance and Protection: The rubber pads on excavator tracks are made from high elasticity, high wear resistance, and high oil resistance rubber materials. They are primarily used to reduce friction between the tracks and the walking mechanism, preventing wear and noise. These track pads are often reinforced with a layer of metal to enhance their wear resistance and lifespan, and they can be customized based on different models of excavators and working environments.

In summary, the application of rubber in excavators encompasses sealing, vibration dampening, wear resistance, and protection. These functions collectively ensure the performance of the excavator and the safety of the operator.
