Shaft bearing for eccentric drive in a radial piston engine incorporates channels between outer periphery and shaft aperture

摘要

A radial roller bearing (1) has an outer ring (2) whose mantle has an inner roller (3) race surface and an inwards-folded ring-shaped rim (5, 6) around a central aperture (7a, b) for an axle or shaft. The rim incorporates one or more channels (8) linking the rim outer periphery with the central aperture (7a).
