Abstract

A compressor bearing assembly for use in a compressor includes an anti-friction rotation bearing and a compressor component. The anti-friction rotation bearing has a first and a second side. The compressor component has a bearing press fitting hole. The bearing press fitting hole has a mouth and a bottom and is formed in the compressor component and is adapted to receive a first side of a rotation bearing. The bearing press fitting hole has a first inner diameter at its mouth and a second inner diameter in the vicinity of its bottom. The first inner diameter is less than the second inner diameter. The structure for the compressor bearing in this invention may strongly and uniformly fix the rotation bearing. Further, this structure prevents the rotation bearing from slating within the pressing hole and prevents undesirable adherence between the rotation bearing and the press fitting hole. As a result, the durability of the rotation bearing and the shaft are improved.
