ABSTRACT:
An elastomer bearing (20) and assembly method therefor. The bearing (20) includes an inner member (22) having an outer profiled surface with a maximum radial dimension, an outer member (24) having a minimum radial dimension which is smaller than said maximum radial dimension and a inner profiled surface. The outer member (24) includes first (26) and second halves (28) being inserted axially over the spherical portion (23) of inner member (22). Each halve (26, 28) including axial threaded portions (32) which are threadedly interconnected to secure halves (26, 28) together. An elastomer layer (30) is bonded to said outer profiled surface of said inner member (22) and said inner profiled surface of said outer member (24). In another aspect, the profiled surfaces are spherical surfaces. Preferably, air is vented into the threaded escapeway (33) during the bonding process. A radial gap (34) is provided to aid is air removal/venting.
