Collapse edit this section features


The rotary damper is based on the change of rotation speed and the torque is also changed. The change rule is: Speed improves, torque also improves. The speed slows down and the torque decreases. The torque is different from the standard torque when starting.

Temperature characteristics

The torque also are varies according to the changing ambient temperature of the rotary damper. The change rule is: The ambient temperature increases when the torque drops, the ambient temperature decreases when the torque rises. This is due to the change of ambient temperature, the viscosity of viscous oil in the damper is also changed. However, when ambient temperatures are restored to normal temperature, torque will also revert to the original value.
