Product Description

The electronic cigarette gear damper is suitable for various small and medium-sized boxes, flip covers, telescopic, and sliding products, such as electronic cigarette flip cover cushioning and fire door handle cushioning. It has a shockproof effect and slows down the door opening and closing speed, making it smooth and fluid, effectively reducing noise generated during product use, enhancing the overall product quality, and increasing the product's lifespan.

Product specifications:

Model	Torque	Damping rotation direction	Maximum rotation angle
LF-40B-5KG	6±1kgf.cm	Clockwise (CW)	125°
LF-40B-10KG	10±1kgf.cm	Clockwise (CW)	125°

Note: 1) The marked torque is based on testing conditions of temperature at 23℃ and humidity at 80%, with the motor speed of the test stand at 20 revolutions per minute; data is measured after the damper rotates for 5 circles.
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.

(Note: This type of damper has two materials for the rotating shaft: PA and zinc alloy. Generally, if torque exceeds 30kgf.cm, it is recommended to use zinc alloy material for the axis.)

阻尼器特性
A．温度特性：
(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 damping oil; torque output decreases with rising temperatures and increases 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 speaking, as rotational speed increases, torque also increases; as rotational speed decreases, torque decreases as well. Additionally, starting torque differs from standard torque.
阻尼器的扭矩在使用旋转速度不同时也会发生变化。一般情况下，旋转速度加快，扭矩也随之增大；旋转速度减慢，扭矩也随之减小。另启动时扭矩与标准扭矩也不同。
