Product Description

　　This bidirectional gear damper has a standard spur gear profile with an involute tooth shape and 11 teeth. The torque range of this damper wheel is 30-100gf.cm, and its stable low torque characteristics make it widely used in various fields, such as shared power bank pop-up covers and car navigation panels.

1. Product Specifications

Model	Torque	Damping Rotation Direction
LF-23B-30G	30-45gf.cm	360° rotation (bidirectional)
LF-23B-50G	50±10gf.cm	360° rotation (bidirectional)
LF-23B-80G	80±10gf.cm	360° rotation (bidirectional)
LF-2B-100G	100±10gf.cm	360° rotation (bidirectional)

　　Note: 1) The marked torque is the data measured after the damper rotates for 5 turns under the conditions of temperature at 23℃ and humidity at 80%, with the test rig motor speed at 36 revolutions per minute.

　　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 gear customization.

5. 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 affect the viscosity of the damping oil, causing torque output to decrease with rising temperatures and increase with falling temperatures. 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.

6. 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
