Rolling bearing arrangement

摘要

A roller bearing assembly includes at least one outer ring (16, 18) with an outer track (24, 26), which is surrounded on its outer side by an outer part (36), and at least one inner ring (20, 22) with an inner track (28, 30), which surrounds the inner part (52). The inner part (52) and the outer part (36) project axially beyond the inner ring (20, 22) and the outer ring (16, 18), so that an explosion prevention gap (62) is formed between the inner part (52) and the outer part (36). The explosion prevention gap (62) is at least substantially linear and cylindrical.

主权项

1. A roller bearing assembly comprising:
an electric motor housing having an opening through a wall of the housing; at least one outer ring having an outer track, an outer part in the opening radially between the housing and the outer track, the outer part surrounding an outer side of the at least one outer ring, at least one inner track opposite of the outer track, an inner part surrounded by the at least one inner track, and a shaft disposed within the inner part, the inner part extending radially between the inner track and the shaft, wherein the inner part and the outer part project in an axial direction of the shaft beyond the inner track and the outer ring, so that an explosion prevention gap is defined between the inner part and the outer part, the explosion prevention gap being at least substantially linear and cylindrical and having an axial length and a radial width selected such that sparks inside the housing cannot ignite gases outside the housing.
