POWER ROLLER BEARING FOR TOROIDAL TYPE CONTINUOUSLY VARIABLE TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To provide a power roller bearing for a toroidal type non-stage transmission being capable of reducing slip between a ball and a rotating face. SOLUTION: A plurality of ball accommodating holes 26 are formed in equal interval positions in the circumferential direction of a holder 24A. The holder 24A is made of an elastic material allowing balls 22 to shift from the equal interval positions. An inner circumference of an opening part 26a of the ball accommodating holes 26 is smaller than an outer circumference of the balls 22. The holder 24A has sufficient elasticity permitting the opening part 26a of the ball accommodating hole 26 to expand more than the outer circumference of the balls 22.
