Abstract
The utility model discloses a damping ring connected with a power machine and a bell-shaped cover. The damping ring comprises a first annular skeleton, a second annular skeleton and a vulcanized rubber ring which is arranged between the first annular skeleton and the second annular skeleton, the first annular skeleton and the second annular skeleton are matched with and aligned to each other, a first inner surface of the first annular skeleton, which is close to one side of the vulcanized rubber ring, extends into the vulcanized rubber ring to form at least two first protrusions, a first installation screw hole is arranged on the first annular skeleton along the axial direction of the damping ring and penetrates through insides of first protrusions, a second inner face of the second annular skeleton, which is close to one side of the vulcanized rubber ring, extends into the vulcanized rubber ring to form at least two second protrusions, a second installation screw hole is arranged on the second annular skeleton along the axial direction of the damping ring and penetrates through insides of second protrusions, and the first annular skeleton, the second annular skeleton and the vulcanized rubber ring are in a vulcanized integrated structure. By the aid of the damping ring, vibration and noises produced by system operation can be reduced and absorbed, the service life of the whole hydraulic system is prolonged, and noise pollution is reduced.
Description
Technical field
The utility model relates to the hydraulic services field, is specifically related to a kind of damping ring that connects power engine and bell cover.
Background technique
At present, in the domestic hydraulic system, bell covers on docking of power engine and handles, what generally adopt is the rigidity butt joint, when the rotation of power engine rotor high-speed caused body vibration, the oil hydraulic pump that can drive bell cover and the bell cover the other end vibrated together, and not only noise is bigger, and effectiveness in vibration suppression is poor, reduces the working life of oil hydraulic pump.
The model utility content
For solving the problems of the technologies described above, the utility model discloses a kind of damping ring that connects power engine and bell cover, both reduced noise, can reduce the power engine vibration again to the influence of whole hydraulic system, prolong the working life of whole hydraulic system.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of damping ring that connects power engine and bell cover, comprise first ring skeleton, second ring skeleton of mutual coupling and centering and be arranged on first ring skeleton and second ring skeleton between the vulcanized rubber ring, described first ring skeleton is extended with at least two first projections towards first internal surface of described vulcanized rubber ring one side in described vulcanized rubber ring; Described first ring skeleton axially offers first along described damping ring screw is installed, and the described first installation screw leads in the described first projection inside; Described second ring skeleton is extended with at least two second projections towards second internal surface of described vulcanized rubber ring one side in described vulcanized rubber ring; Described second ring skeleton axially offers second along described damping ring screw is installed, and the described second installation screw leads in the described second projection inside; Described first ring skeleton, second ring skeleton and vulcanized rubber ring are the vulcanized rubber material.
Preferably, described first projection and first is installed screw, described second projection and second is installed screw, distributes along its circumference circular array alternate intervals in described damping ring.
Pass through technique scheme, a kind of damping ring that connects power engine and bell cover of the present utility model, at the described first ring skeleton internal surface, the second ring skeleton internal surface described first projection, second projection are set respectively, and employing vulcanization of rubber integrated technique, therefrom described vulcanized rubber ring and described first ring skeleton, second ring skeleton are vulcanized one, realize flexibly connecting between two ring skeletons; It can effectively reduce and filter vibration and noise that absorption system running produces, and vibration reduces, filter 23 is more than 0%, has prolonged the life-span of whole hydraulic system; Noise can reduce 6-10dBA, has reduced the pollution that noise produces surrounding enviroment.
