There are many kinds of rubber seals for engine damping pads, and rubber damping pads have been widely used in the field of engine damping and noise reduction because of their small size, low cost and easy adjustment of elasticity and stiffness. Therefore, at present, almost all diesel engine supports of bulldozers use damping rubber. Rubber vibration damping is used at the support part, which has high requirements for the joint surface, and attention should be paid to high temperature resistance and oil erosion. Pay attention not only to the vibration isolation when the diesel engine rotates at high speed, but also to the vibration isolation when the diesel engine idles, starts and stops, as well as to prevent the resonance of all parts of the body.
The application effect on the crawler guide wheel takes the rubber shock absorber installed at the guide wheel of a crawler bulldozer as an example, showing the installation position of the rubber shock absorber, indicating its shape, and its shape is like a wedge-shaped "sandwich", which is used to buffer and reduce vibration in both vertical and horizontal directions.
Working temperature of shock absorber rubber: -30 ~ 60 ℃; Maximum amplitude of vibration load: 270kn; Load frequency: 012 ~ 200Hz; Main load action frequency: 4 ~ 8Hz. For small amplitude vibration load, the shock absorber can absorb more than 80% of the vibration energy; For impact load, more than 50% of impact energy can be dissipated.
