Torque limiter (also called torque limiter, safety coupling, safety clutch) is a component that connects the active machine and the working machine. The main function is overload protection. The torque limiter is caused by overload or mechanical failure. When the required torque exceeds the set value, it limits the torque transmitted by the transmission system in the form of slipping. When the overload condition disappears, the torque limiter automatically restores the connection. This prevents mechanical damage and avoids costly downtime losses. The torque limiter adopts a spring-loaded friction surface, and the spring force is adjusted with a nut or bolt to preset its sliding torque. The working principle of torque limiter can be divided into friction type torque limiter and steel ball type torque limiter (ball type torque limiter). The range of torque limiter: electronic equipment industry, automated production line, conveyor industry, etc.

Selection method: Determine the required slip torque by the load condition or the design strength of the machine. If the load condition of the machine is ominous, set the slip torque of the torque limiter to 1.2~2 times the torque produced by the motor related to the installed shaft .

Please select a torque limiter with sufficient torque range and inner diameter range. The correct shaft sleeve length is determined by the thickness of the center member between the friction plates. The selection of the shaft sleeve cannot be greater than the width of the center member and the maximum thickness of the center member.
