AI Technical Summary
The existing roll shafts suffer severe wear during processing, leading to processing errors and frequent replacements, which increases replacement costs and labor costs, and reduces production efficiency.
Design a roll shaft with a second groove for wrench insertion and removal. The design of the marking and the first groove allows the roll shaft to be used multiple times after wear by rotating and reversing. Axial rotation is achieved by using a thrust bearing and needle rollers, and a set screw is used for limiting and extending service life.
The rotary face-changing technology extends the service life of the roll shaft, reduces procurement and labor costs, and improves production efficiency.
