Rotary Damper for Automatic Mahjong Machine

1. Suitable for the following products:

Torque rotary damper can be applied on all kinds of home appliance, consumer electronic products and automobiles, such as rotary damper on TV control panel lid, rotary damper on CD drawer, rotary damper on cassette player, rotary damper on all control panel covers.
High precise torque rotary damper makes products more valuable with the smooth motion control that brings from rotary damper. Plastic rotary damper can make soundless, and with the smooth motion control function that rotary damper brings, it can also extend the life of products.

2. Material:
Shell\\cover: PC
Axis core/gear: POM
Seal ring: Silica gel
Damping oil: Silicone oil

3. Product parameters:
Module: 0.8
Number of teeth: 10
Pitch circle: 8.0
Pressure angle: 20°
Resistance range: 40-220gf. Cm

4. Basic principles:
The torque made by the damping oil to the rotating parts cohesion effect is the resistance. The value of the resistance is decided by the viscosity and contact area is bigger, the resistance is bigger, and vice versa.
