LF-26A 360° Bidirectional Rotating Gear Damper
Classification:
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 value 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 value; conversely, lower viscosity and smaller contact area lead to a smaller resistance value.
Product specifications:
| Model | Torque | Damping rotation direction |
| LF-26A-50G | 50-80gf.cm | 360° rotation (bi-directional) |
| LF-26A-100G | 100±20gf.cm | 360° rotation (bi-directional) |
| LF-26A-150G | 150±20gf.cm | 360° rotation (bi-directional) |
| LF-26A-200G | 200±20gf.cm | 360° rotation (bi-directional) |
| LF-26A-250G | 250±20gf.cm | 360° rotation (bi-directional) |
| LF-26A-300G | 300±20gf.cm | 360° rotation (bi-directional) |
Note: 1) The marked torque is tested under conditions of temperature at 23℃ and humidity at 80%, with a motor speed of 36 revolutions per minute on the test stand, measuring data after the damper rotates for 5 circles;
2) Torque customization can be provided by changing the viscosity of the damper grease;
3) The maximum operating temperature range for the damper: -40℃ to +90℃;
4) This series of dampers can provide gear customization.

(Damper characteristics)
A. Temperature characteristics
The torque generated by the damper will change under the influence of environmental temperature. This is because changes in temperature will cause variations in the viscosity of damping oil, with torque output decreasing as temperature increases; conversely, it increases as temperature decreases. 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 accordingly. 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
