High Torque Soft Closing Rotary damper For Rice Cooking
The resistance torque can be customized
The rotary damper can make the product closing smoothly
Rotary Damper Usage
Our rotary dampers apply to sitting WC pan clamshell, hospital bed and other electronic clamshell products. It reduces the nioses during the using process of the above products, advances the products level, and express the products humanity concept.
Rotary Damper Basic Prinsiples
The torgue 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.
Rotary Damper Resistance and The Testing Method
In the production testing under normal 27.5 degree, put the rotary damper on the axis rotating in a speed of 36r/min, and the resistance in the 3rd rotate is the standard one. Commonly, the resistance can be adjusted from 5Kg to 15Kg.
