Lid rotational soft close dampers for door manufacturers in China.
Lid rotational dampers soft close for doors, refrigerator, washing machine. What is rotary damper. The damper is a device that provides the resistance to motion and reduces the energy of the movement. The use of damping to absorb energy is not a new technology. In the aerospace, aviation, military, gun, automotive and other industries, various dampers (or shock absorbers) have long been used to reduce energy dissipation.

How To Use The Damper?
1. TRD-P1 is designed to generate a large torque just before a lid
closing from a vertical position, as shown in Diagram, comes to a full closure. When a lid is closed from a horizontal position, as shown in Diagram, a strong torque is generated just before the lid is fully closed, causing the lid to not close properly.
2. When using a damper on a lid, such as the one shown in the diagram, use the following selection calculation to determine the damper torque.
Example) Lid mass M: 1 kg
Lid dimensions L: 0.3m
Load torque: T=1X0.3X9.8÷2=1.47N·m
Based on the above calculation, TRD-P1-*153 is selected.
3. When connecting the rotating shaft to other parts, please ensure a tight fit between them. Without a tight fit, the lid will not slow down properly when closing. The corresponding dimensions for fixing the rotating shaft and the main body are as follows.
