摘要： A power roller bearing of a toroidal-type continuously variable transmission unit that is used for a transmission of an automobile or the like comprises a power roller, an outer race, balls, a retainer, etc. Annular raceway grooves are formed individually on the respective opposite end faces of the outer race and the power roller. Treated-surface layers for enhancing the endurance of the power roller bearing are formed individually on the respective surfaces of the raceway grooves. The treated-surface layers include super-finished surfaces with the surface roughness of 0.05 Rad or less, formed individually on the raceway grooves, and low-friction layers formed individually on the super-finished surfaces. Alternatively, the treated-surface layers include residual compression stress layers formed on the respective surface layer portions of the raceway grooves by shot-preening.

摘要： In the toroidal-type continuously variable transmission, the torque transmission shaft 15 includes a flange portion 29a formed in one end thereof, while a securing portion 43 is formed in the end-face side half section of the flange portion 29a so as to be able to secure a tool thereto when tightly fastening a loading nut 19 to a external thread portion 40 formed in the torque transmission shaft 15. And, the outer peripheral surface of the securing portion 43 is formed as a polygonally cylindrical shape having four or more flat surfaces. Also, after the torque transmission shaft 15 is heat-carburized and the surface of a cylindrical portion 44 formed in the torque transmission shaft 15 is removed, the external thread portion 40 is worked, which makes it possible not only to secure the hardness of the adjoining portions of the external thread portion 40 but also to control the hardness of the external thread portion 40 itself. Further, branch oil supply passages 39 and 39 used to supply oil to ball splines 17 and 17 are formed at the positions of the torque transmission shaft 15 that are shifted in the axial direction of the torque transmission shaft 15 from the positions of balls 37, 37, which respectively construct the ball splines 17 and 17.

摘要： In the toroidal-type continuously variable transmission, the radial clearance of a second radial needle roller bearing 30 for supporting the power roller 8 on the periphery of the pivot shaft portion 26 of the displacement shaft 7 is set larger than the radial clearance of a first radial needle roller bearing 27 for supporting a support shaft portion 25 on a trunnion 6. By increasing the radial clearance of the second radial needle roller bearing 30 in this manner, an increase in the surface pressures in the contact portions between the rolling surfaces of needle rollers 32, 32 and the inner peripheral surface of the power roller 8 and the outer peripheral surface of the pivot shaft portion 26 can be restricted, thereby enhancing the durability of the toroidal-type continuously variable transmission. Also, by reducing the radial clearance of the first radial needle roller bearing 27, the inclination of the displacement shaft 7 is minimized, thereby stabilizing the rotation speed change operation thereof.

The trunnion includes a base portion having a body portion, which connects and supports a base end portion of a displacement shaft at a surface intermediate portion, and a pair of plate portions, in which an edge apart from the body portion is a tip end edge, and a pair of axis (shaft) portions protruding from the outside surfaces of the plate portions in opposite directions to each other. The toroidal continuously variable transmission is characterized in that at least the rolling surface of a radial needle bearing for supporting the tilted rotation of the trunnion has a hardness not lower than HRC55, and a core portion has a hardness not lower than HRC20 and not higher than HRC45.
