ABSTRACT:
This disclosure relates to bearing support comprising a relatively rigid collar ring for direct support of a bearing. The relatively rigid collar ring is press fit inside a bearing supporting hub of a nonmetal (such as a composite polymer) bearing support. The design of the relatively rigid collar ring and the composite polymer bearing support is such that the stresses in the construction are satisfactory for long-term performance and reliability. The bearing supporting hub includes discrete supporting hub panels and there are axial slots between the hub panels. The supporting hub panels further include radial rib sections extending axially for strengthening the supporting hub panels and for adding support for the relatively rigid collar ring. The inside diameter of the supporting hub panels is tapered to provide stress relief clearance. Contacts between the inside of the supporting hub panels and the collar ring are limited to discrete locations. Contacts between the ribs of the supporting hub and the collar ring are also discrete by nature of the discrete radial ribs. The relatively rigid collar ring also provides a flat surface for bearing a thrust load.
