AI Technical Summary
The idler roller shaft of the rehydration machine for the spinning line is far from the bearing at the connection point with the reducer, which causes the bearing to be subjected to a large bending moment and breakage, affecting the stability of the equipment and the quality of the products.
An additional bearing is added between the reducer and the original idler roller support bearing. This bearing is fixed with brackets and bolts to form a three-bearing support structure, which reduces the bending moment at the end of the idler roller shaft.
It effectively protects the idler roller shaft, reduces equipment failure rate, and improves product quality and equipment stability.
