They have the functions of shockproof and slowing down the opening and closing speed. The damper usually includes a housing, a shaft and a sealing component. The shaft is rotatably installed in the housing. Usually, the height of the housing is not high, so the rotating body of the rotating body is a ring body with a relatively thin side wall and a small damping area. The applicability is limited. After long-term use, the damping oil in the gap is unevenly distributed, which affects the stability of the shaft, thereby affecting the overall shockproof and opening and closing speed slowing effect of the gear damper.
