Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of shock absorbers and relates to a shock-absorbing shell used for assembling an inertia ring. Background Art
[0002] Shock absorbers are used for vibration reduction, and the inertia ring is a metal ring-shaped device installed on the shock absorber, mainly to increase the mass inertia of the shock absorber. The damping ratio and transmission power of the shock absorber are closely related to the mass inertia, and the role of the inertia ring is to increase the mass inertia of the shock absorber, thereby improving the damping ratio and transmission power. Therefore, a closed cavity for the installation of the inertia ring is opened on the shock absorber shell, but a certain gap is formed between the inertia ring and the closed cavity, and the gap is filled with a high-viscosity liquid-silicone oil. When working, the inertia ring rotates at a uniform speed due to inertia, and a relative motion is formed between the inertia ring and the shell. The vibration energy of the crankshaft is absorbed by the internal friction damping of the silicone oil, thereby reducing the torsional vibration of the shaft system. However, in actual use, the inertia ring may rub against the shell, causing it to wear, thereby affecting the subsequent vibration reduction effect. Summary of the invention
