Influence of assembly condition on no-load starting torque of spherical plain bearing
To study the influence of the assembly condition on the no-load starting torque of the spherical plain bearing,the finite element model for assembling joint bearings is built in Abaqus.The influence of bolt tightening force and chuck to outer ring assembly type on the no-load starting torque is analyzed.The results show that:the no-load starting torque of the bearing and its fluctuation during oscillation increases with the bolt tightening force;while the assembly status of the chuck and outer ring of the spherical plain bearing is changed from a clearance fit to an interference fit,the no-load starting torque of the bearing and its fluctuation during oscillation increases obviously.The test proves that the no-load starting torque of the spherical plain bearing and its fluctuation during oscillation can be maintained in a certain range by controlling bolt tightening force and chuck to outer ring assembly type.
