摘要： In a toroidal type continuously variable transmission, first pivot shafts provided on both ends of first trunnions are supported within support holes formed in yokes secured to an inner surface of a casing. The support portions are provided with ball splines and radial needle bearings. During operation, loads acting on the first trunnions are cancelled within the yokes. Axial displacements and rocking displacements of the first trunnions are effected smoothly by the ball splines and the radial needle bearings.

摘要： The disk has a traction surface having a concave-arc-shaped cross section which is interposed between a small diameter end portion and a large diameter end portion. In the central portion of the end face of the disk on the small diameter end portion side, there is formed a through hole which extends through the disk up to the large diameter end portion side end face of the disk, while the inner peripheral surface of the through hole is used as an inside diameter surface of the disk. Here, when, among metal flows existing in the disk, a metal flow, which has such a positional relationship with respect to the surface of the disk that an angle .theta. formed between a metal flow on the traction surface side and the tangent of the traction surface is smaller than or equal to 30 degrees, is defined as a "metal flow along the disk surface", the disk is structured such that the "metal flow along the disk surface" exists at least in the traction surface.

摘要： The ball spline for use in a troidal-type continuously variable transmission comprises a plurality of spline grooves and a plurality of balls which are arranged in series within spline gaps each constituted by a set of mutually opposing spline grooves, in which, while allowing the movement of the input disc in the direction of an input shaft by means of contact between the spline gaps and balls, the input shaft and input disc can be drivingly connected to each other. In the ball spline, the number of spline gaps is set different from integral multiples of the number of power rollers which are held by and between the input and output discs in contact with the two discs in order to transmit a rotation torque between the input and output discs. Further, each of the spline grooves includes inner and outer peripheral surface side spline grooves, and the shape of each of the sections of the two inner and outer peripheral surface side spline grooves respectively forming the ball spline is formed as a Gothic arch shape. And, the radius of curvature of the section of the groove bottom portion arc surface forming the groove bottom portion of each of the spline grooves is set more than or equal to 15% of the diameter of the ball. Also, the outer peripheral surface side chamfers of the outer peripheral surface side spline groove are set smaller to thereby be able to secure the effective grinding surface of the outer peripheral surface side spline groove.
