AI Technical Summary

Technical Problem

In existing gear dampers, the damping oil distribution is uneven, affecting the stability of the rotation shaft, thereby affecting the overall shockproof and slowing down the opening and closing speed.

Method used

A new type of gear damper is designed, by forming a damping cavity between the rotating body outer wall and the inner wall of the shell, and a barb is provided in the middle inner wall of the gear. The cross-section of the barb is triangular and is stuck on the oil storage tank to prevent the damping oil from falling off. At the same time, the convex body and U-shaped groove structure provide the storage space of the damping oil and the uniform resistance of the flow blocked.

Benefits of technology

It achieves uniform distribution of damping oil and lasting damping effect, extends service life, and makes the damper's shockproof and slows down the opening and closing speed more stable and uniform.

Abstract

The utility model relates to the technical field of damping devices, in particular to a novel gear damper. A novel gear damper comprises a shell and a rotating body, a cylinder is arranged in the center of the shell, the rotating body is clamped on the cylinder, a damping cavity is formed between the outer wall of the rotating body and the inner wall of the shell, damping liquid is injected into the damping cavity, a rotating shaft is arranged in the center of the top of the rotating body and penetrates through a cover plate, the cover plate is arranged on the shell in a sealed mode, and the rotating shaft is sleeved with a gear. The lower part of the rotating body is provided with a rotating body, the outer wall of the rotating body is sunken, the inner side between the rotating bodies is provided with a U-shaped groove, and the two sides of the rotating body are provided with inclined planes. The gear has the advantages that the barbs are arranged on the inner wall of the middle of the gear, the cross sections of the barbs are triangular, the barbs are clamped on the oil storage grooves and prevented from falling off, the outer wall of the rotating body is sunken, the U-shaped grooves are formed in the inner sides between the convex bodies, the two sides of the convex bodies are inclined faces, even resistance is obtained due to the fact that flowing of damping oil is blocked, the damping effect is lasting, and the service life is long.
