Toroidal type stepless transmission for e.g. motor vehicle enlarges radial clearance of radial needle bearing for power roller shaft more than radial clearance of radial needle bearing for support frame

摘要

A radial clearance of the secondary radial needle bearing (30) is enlarged more than radial clearance of the primary radial needle bearing (27). The secondary radial needle bearing is provided around a support shaft (26) of a power roller (8). The primary radial needle bearing supports a support frame (25) to the trunnion (6).
