How to adjust the torque of a ball-type torque limiter?
The ball-type torque limiter is a common mechanical component that consists of an outer disk, an adjustment screw, a compression spring, and internal friction elements such as steel balls. Its main function is to limit or control the torque of rotating devices in order to protect equipment and operators. The torque of a ball-type torque limiter can be adjusted by adjusting the adjustment screw, so understanding its working principle and structure is important before making any adjustments. Here is a step-by-step guide on how to adjust the torque of a ball-type torque limiter:

1. Loosen the lock nut: Firstly, locate the adjustment screw, which is usually positioned externally on the torque limiter. Use the appropriate tool to loosen the lock nut, ensuring that the screw can rotate freely.

2. Rotate the adjustment screw counterclockwise: The adjustment screw is usually threaded. By rotating it counterclockwise, the friction between the torque limiter's friction elements (such as balls) and the disks can be increased.

3. Test the torque: After adjusting the screw, conduct a test to confirm if the torque limiter's operation meets the requirements. This can be done by applying a specific torque and observing whether the steel balls start rolling to limit the torque. If the torque limit is too high, you can slightly rotate the screw counterclockwise to decrease the torque.

4. Tighten the lock nut: Once the desired torque limit is achieved, rotate the adjustment screw to the appropriate position and use the proper tool to tighten the lock nut on the torque limiter, preventing it from unintentionally rotating.
It is important to exercise caution when adjusting the torque of a ball-type torque limiter. An excessively low or high torque limit may have negative impacts on the normal operation of the mechanical system. Before adjusting the torque limiter, it is recommended to understand the equipment requirements and refer to the operating manual provided by the manufacturer, as different devices may have varying adjustment methods and requirements. Alternatively, it is advisable to seek assistance from experienced technicians. If you have any specific questions or need further guidance on adjusting the torque limiter, please consult the manufacturer - Shanghai Xinde. They will provide you with the necessary instructions based on your specific situation to ensure that the adjusted torque limiter functions properly and ensures the safety of your equipment.
