Problems solved by technology

However, the pre-tightening force of the screw pair is generally preset by the manufacturer, and cannot be adjusted automatically during the processing. Long-term work and wear will cause changes in the pre-tightening force, thereby reducing the transmission accuracy.
The adjustment and maintenance of the preload need to be done manually, which will consume a lot of manpower and material resources
