Note: 1) The marked torque is the data measured after the damper rotates for 5 turns at a motor speed of 36 revolutions per minute under conditions of temperature at 23℃ and humidity at 80%;
2) Torque customization can be provided by changing the viscosity of the damper grease.
3) Maximum operating temperature range of the damper: -40℃ to +90℃.
4) This series of dampers can provide customized gears.

Damper Characteristics

A. Temperature Characteristics:
The torque generated by the damper will change when affected by environmental temperature. This is because changes in temperature will affect the viscosity of the damping oil; torque output decreases with increasing temperature and increases with decreasing temperature. When the temperature returns to normal, the torque also returns to its original value.

B. Speed Characteristics:
The torque of the damper will also change when using different rotational speeds. Generally, as rotational speed increases, torque also increases; as rotational speed decreases, torque decreases as well. Additionally, starting torque differs from standard torque.

Specific Usage Methods for Gear Dampers

A. Gear and rack fit (linear motion of workpiece)

B. Gear and gear fit (rotational motion of workpiece with angle limitation)

C. Gear and gear fit (no angle limitation)

D. Workpiece directly connected to damper rotation axis
