AI Technical Summary
In existing gear dampers, the silicone oil distribution in the gap between the rotating shaft and the receiving cavity is uneven during use, which affects the stability of the rotating shaft and results in poor shock absorption and slowing down the opening and closing speed.
A gear damper was designed, employing two damping structures, including a rotating body and a rotating body. Through the design of the stop and the convex ring, a uniform damping effect is formed. The friction between the stop and the damping oil generates uniform resistance, enhancing the durability of the damping effect.
This achieves uniform and durable damping effect, improving the service life and shock resistance of the gear damper.
