Silicone oil shock absorber

Abstract

The invention relates to a silicone oil shock absorber. The silicone oil shock absorber comprises a silicone oil shock absorber shell, an inertia block, a cover plate and a bearing belt, wherein the center of the silicone oil shock absorber shell is provided with a through hole in which an engine crankshaft is sleeved; the periphery of the silicone oil shock absorber shell and the cover plate form a circle of cavity; the inertia block is accommodated in the cavity; the inertia block and the silicone oil shock absorber shell are separated axially by the bearing belt; the gap between the inertia block and the silicone oil shock absorber shell is filled with silicone oil; the inertia block, the bearing belt and the silicone oil are sealed in the silicone oil shock absorber shell by the cover plate; and radiating fins are welded on the two sides of the silicone oil shock absorber shell. The silicone oil shock absorber has the advantages that: the silicone oil shock absorber can effectively reduce the tensional vibration of the engine crankshaft, has a compact structure, reduces installation volume and is convenient to install; due to the addition of the radiating fins, not only a radiating effect is achieved, but also a decorative effect is achieved; simultaneously, engine weight, component number and production management cost can be reduced.

Description

technical field [0001] The invention discloses a shock absorber, in particular to a silicon oil shock absorber for a crankshaft of a diesel engine. Background technique [0002] At present, shock absorbers mainly include rubber shock absorbers and spring shock absorbers. Among them, the shock absorption effect of spring shock absorbers is limited, and the springs are prone to deformation and failure after a long time of use; The main purpose of the shock absorber is to change the position of the resonance point in the speed range, and it can only be effective in a specific speed range; the silicone oil shock absorber is a shock absorber with a main damping effect, which uses its own damping to absorb vibration energy. Both dots and out-of-resonance regions are effective. [0003] Construction machinery generally has relatively large power and torsion, and the working conditions are harsh, such as high temperature. The rubber element absorbs too much energy and will age qui...
