Cross shaft

  Cross-axis needle roller bearings Bowl is mainly because: U-shaped bolts too tight, more than the provisions of the torque; U-bolt tightening method of improper operation (never first U-bolts a nut tightened, and then screw the other Nut) to U-bolts and cross-shaft bearing bowl contact surface contact bad, local force fragmentation. Fork-shaped flange semi-circular hole at the cross-axis axis positioning a small convex, universal shaft which is good ? In the maintenance of the repair of the cross shaft, if the bearing bowl bottom slot mistakenly limit the bearing bowl rotation positioning groove, and the fork on the positioning of the boss in the bottom of the bearing bowl, will cause the cross shaft axial clearance increases 3Inm (normal fit only allow 0.20mln maximum), so the cross shaft axial movement increased, and by the centrifugal force of the impact, so that the drive shaft assembly loss of dynamic balance, resulting in vibration, bearing steel bowl is also easy to damage. Another needle roller bearings off the needle missing, issuing cards, etc., will make early damage.
