What Is a Torque Limiter?
Torque limiters are devices that protect equipment from overload and contribute to improved productivity.
They are mainly used in multilevel parking lot turntables, pallet cart conveyors, and various types of training machines.
Applications of Torque Limiters
Torque limiters are used for three main purposes: accumulation, breaking, and dragging.
Accumulation stops the driven side in position using a stopper action. An example of a practical application is a conveyor that utilizes the stopper action.
Braking stops continuously driven equipment by braking action. An example of a practical application is a turntable in a multilevel parking garage that utilizes braking.
Dragging applies a steady load to a device using a slipping action. An example of a practical application is a training machine that utilizes the slipping action.
Principle of Torque Limiters
Torque limiters are devices that maintain a constant torque. The basic configuration of the device is generally made up of seven mechanical parts: hub, plain bearing, flange, plate, disc spring, washer, and adjusting nut.
The device transmits drive to an external drive up to a specified torque, but slips and stops transmitting drive when the specified torque is exceeded. Torque adjustment is determined by loosening or tightening an adjusting bolt attached to the far end of the device. The torque setting range varies from 10 to 30 Nm for small products and from 100 to 600 Nm for large products.

Features of Torque Limiters
1. Compact and Lightweight
The device consists of only a few mechanical parts, making it compact and lightweight.
2. Built to Last
The use of chemical fiber for the plate extends the life of the device.
3. Low-Cost and Lightweight
The use of aluminum for the flange enables low-cost and lightweight equipment.
4. Easy Torque Adjustment
Torque adjustment is easy by simply turning the adjustment bolt according to the torque scale.
