LIGHTWEIGHT HYBRID BEARING ASSEMBLY AND A METHOD OF MAKING THEREOF

摘要

A lightweight hybrid bearing assembly (110; 210; 310) and method of making thereof is disclosed. The bearing assembly includes an inner race (124; 224; 324) and an outer race (126; 226; 326) radially spaced from the inner race. One or both of the inner race and the outer race have a convex bearing surface (150, 148; 250, 248; 350). Between the inner race and the outer race, a plurality of ceramic roller elements (128; 228; 328) are received. The ceramic roller elements have a concave bearing surface (146; 246; 346) that engages the convex bearing surface or surfaces. Among other things, this accommodates axial misalignment of the races relative to one another.
