The cage motion with different pocket shapes, such as spherical, square, and cylindrical, in an angular contact ball bearing under different operating conditions are studied experimentally. A test rig with two laser displacement sensors is used to obtain the displacements of the cage in five freedom degrees. The results reveal that these three type cage shapes have different trends of the centroid trajectory versus rotating speed or radial load. The whirling radius is equal to half of the pocket clearance for the spherical pocket, and half of the guiding clearance for both square and cylindrical pocket. The slip rates of all cages decrease with increasing radial load, and increase with rotating speed. Both inclination angel and slip rate of the spherical, cylindrical and square pocket decrease in turn. more...
