Product Details

Torque limiter is a component that connects the driving machine with the working machine. Its main function is overload protection. When the torque limiter exceeds the set value due to overload or mechanical failure, it limits the transmission of the transmission system in the form of slip. The torque and slip can also stop the motor and reducer with a signal output, and restore the connection by itself when the overload situation disappears.

The HaiYu Torque Limiter is a good overload protection device whose function is to limit the torque in the drive system by slipping when the sudden load, overload or stop causes the torque to exceed the preset value. When the overload is removed, it can automatically return to the position without re-commissioning the settings. The Otis Torque Limiter prevents equipment damage and eliminates downtime. It works by using a spring mounted on the friction surface. The slip torque can be adjusted by adjusting the nut or bolt. The central element that can be clamped between the two friction surfaces is used in conjunction with a sprocket, gear, pulley or flange. The function is combined with the optimum spring load and surface pressure to ensure a long slip time, maintain a predetermined torque response, and provide long-term continuous protection. The biggest advantage compared to a one-time remedial safety pin system.

1. Determine the required slip torque according to the load conditions or the force of the device itself. If the equipment load conditions are unclear, set the slip torque to 1.5-2 times the torque generated by the motor on the shaft of the load limiting device.

2. When using the torque limiting device, choose a torque range and a sufficient aperture range. 3. Determine the appropriate liner width based on the thickness of the center member of the two friction plate intermediate clips.

1. The friction surface of the intermediate component should be machined to ensure the rated torque. As well as flatness, parallelism, consistent with the hole and anti-rust, anti-oil, recommended surface roughness Ra1.6, if the central component can not meet the above technical requirements, the slip torque will be unstable.

2. Please machine the hole of the center component according to the following table, and select the minimum number of sprocket teeth and the shaft width.
