Inclination of supporting roller bearing seat
A Causes:
1) the center line of the idler is skewed too much, and the axial thrust of the idler shaft is too large;
2) After adjusting the idler, the bolt connecting the bearing and the base is not fastened in time.
B Rectification method:
1) strictly control the external oblique angle of the center line of the idler, which shall not exceed the specified range, and adjust the thrust of the idler to be uniform;
2) Tighten the bolts in time after adjustment.
The idler bearing vibrates.
A causes:
1) the axial thrust of the roller shaft is too large;
2) The radial pressure of the idler is too high.
3) Adjust the idler incorrectly, so that the center lines of the idler on both sides of the first gear are in the shape of an eight.
B Rectification method:
1) adjust the idler to reduce the axial thrust;
2) Adjust the idler to reduce the load;
3) Correct the wrong adjustment in time, and keep the thrust of the supporting wheel consistent upward and even in size.
