Cross on step portion 15, the portion of its outer of connecting shaft 10 and be provided with safe back-up ring 14.Another part of connecting shaft 10 enters rolling
Bearing 12 in wheel 11, carries out axial direction with the bearing inner race of bearing 12 and is connected, the two ends of bearing inner race are respectively arranged with bearing rib
Circle 13.Spreading glue on the outer surface of connecting shaft 10, connecting shaft 10 is connected with bearing 12, connecting shaft 10 and step portion
Also spreading glue on 15 contact surface, connecting shaft 10 is tightened up with step portion 15.But the assembling effect of glue is bad,
Easily cause install failure.And because the step portion 15 of roller 11 and elevator is all moving component, so glue can be released,
Occur gap between connecting shaft 10 and bearing 12 and step portion 15, so connecting shaft 10 and bearing 12 and step portion 15 it
Between relative rotation occurs, eventually result in the Joint failure between connecting shaft 10 and bearing 12, roller 11 and step portion 15,
And further connecting shaft 10 may damage step portion 15.
