The safety clutch is used to accurately limit the transmitted torque. When the torque exceeds a certain limit value, it is a clutch that protects (separates). When the transmission torque does not exceed the limit value, its function is equivalent to a coupling.It is mainly used in transmission systems where large overloads and severe shocks may occur during work.
The shear pin safety clutch is divided into flange type and sleeve type.There are two types of safety pins: plain pins and grooved pins. The latter has better performance, easy replacement and wider application.
Jaw-type safety clutch: The tooth shape is usually trapezoidal, and it is pressed by a spring when working, so that the tooth can be easily separated. Generally, the tooth shape angle of the working surface is 30°~45°.
The steel ball type safety clutch replaces the teeth with steel balls. The contact form of the steel balls can be divided into steel ball to steel ball and steel ball to tooth (tapered hole, etc.).
There are many types of friction type safety clutches, such as dry type, wet type, disc type, cone type, single disc type and multiple disc type.
