    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.

    摘要: In order to improve the transmission efficiency of a toroidal type continuously variable transmission by reducing the dynamic torque loss of an antifriction bearing, a first output gear is constituted by a pair of helical gears of which the directions of inclinations are opposite to each other, and a second output gear is constituted by a double helical gear. By this construction, a thrust force created in the meshing portion between the first and second output gears is offset and the dynamic torque loss of the antifriction bearing is reduced.

    摘要: In order to prevent strong bending stress given to outer rings of thrust ball bearings of power roller assemblies and to improve the durability of the outer rings, a toroidal-type continuously variable transmission has thrust needle bearings which absorb thrust load given to the outer rings as well as allow the outer rings and corresponding trunnions to be shifted from each other. Preferably, the entire circumference of the pitch circle of the balls of each thrust ball bearing overlaps with a load-absorbing region, which is one or more annular and/or arcuate regions having the same width as the needles of needle bearings radially arranged in said regions in order to absorb thrust load.

    摘要: Construction of a friction roller reducer is achieved wherein displacement of intermediate rollers due to the change in thickness in the axial direction of loading cam apparatuses can be performed smoothly, and excellent transmission efficiency can be obtained. Long guide holes that are long in the radial direction of a sun roller and ring-shaped roller are provided in guide blocks that are fastened to a support frame for supporting the end sections of rotation shafts of intermediate rollers. The outer rings of ball bearings, of which the inner rings are fitted around and fastened to the outside of the end sections of the rotation shafts, engage with the long guide holes so as to be able to displace in the radial direction of the sun roller and the ring-shaped roller.

    摘要: A sleeve 28 making up a gear ratio control valve 21 is driven by not only a stepping motor 29 but also a secondary actuator 47. Pressure oil is made free to be introduced into the secondary actuator 47 through a manual oil pressure switching valve 37 which is switched over by a gearshift. Then, when the gearshift is operated from a non-running state to a running state, a gear ratio of a toroidal type continuously variable transmission is corrected by a predetermined amount by driving the sleeve 28 by the secondary actuator 47. As a result, while improving characteristic of a vehicle when starting from rest, the vehicle can be prevented from being reduced in speed unintentionally excessively even when the gearshift is operated while running.
