AI Technical Summary

Technical Problem

Existing mill gear-gear machines are prone to incomplete contact during the rolling process, resulting in low contact force on the gear tooth surfaces and difficulty in forming effective contact marks.

Method used

Design an open-type adjustable loading device for large and small gears, using a clamp structure for the upper and lower loading devices. By adjusting the tightening torque of the nut, the frictional torque of the loading at the upper and lower ends of the small gear shaft is the same, ensuring uniform force along the entire tooth length.

Benefits of technology

It achieves uniform contact force on the tooth surfaces of large and small gears, solves the problem of loose connection, has an ingenious structure, is easy to operate, has strong adaptability, and has wide application value.
