Coil spring torque limiter
What is structure of coil spring torque limiter?
A coil spring is press-fitted in the sleeve, and when it turns, it slides and generates torque. The more it tightens a coil spring, the more it generates torque, but the more loosen coil springs, the lower it generates torque. Continue Reading

Characteristics of temperature and speed dependence
Oil dampers have characteristics of temperature and speed dependence.
In general, the viscosity of liquid changes greatly with temperature. Especially the viscosity of oil changes markedly as temperature changes. The viscosity decreases as the temperature rises and the viscosity rises as it goes down. This phenomenon is called temperature characteristic. Continue Reading
