Product Description

The damper mainly utilizes the principle of fluid resistance to reduce vibration and can be used for different gears and torque devices. The damper generates torque (gf.cm) due to the rotation of the damping oil medium, and the magnitude of the resistance is determined by the viscosity of the damping oil and the contact area. Higher viscosity and larger contact area result in a larger product resistance; conversely, lower viscosity and smaller contact area lead to a smaller resistance.

Product specifications:

Model	Torque	Damping rotation direction
LF-26B-50G	50-80gf.cm	360° rotation (bidirectional)
LF-26B-100G	100±20gf.cm	360° rotation (bidirectional)
LF-26B-150G	150±20gf.cm	360° rotation (bidirectional)
LF-26B-200G	200±20gf.cm	360° rotation (bidirectional)
LF-26B-250G	250±20gf.cm	360° rotation (bidirectional)

Note: 1) The marked torque is measured under conditions of temperature at 23℃ and humidity at 80%, with a test rig motor speed of 36 revolutions per minute, after the damper has rotated for 5 circles.
2) Torque customization can be provided by changing the viscosity of the damper oil.
3) The maximum operating temperature range for the damper: -40℃ to 90℃.
4) This series of dampers can provide gear customization.

阻尼器特性

A. Temperature characteristics:
The torque generated by the damper will change under the influence of environmental temperature. This is because changes in temperature affect the viscosity of the damping oil, causing torque output to decrease with rising temperatures and increase with falling temperatures. When temperature returns to normal, 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 rotating shaft
