摘要： Improved input and output discs for toroidal type continuously variable transmissions are obtained by select processing techniques to form hardened layers. Processing techniques include, e.g., carburizing, carbonitriding, and high-frequency induction hardening. Shot peening may be used to impart compressive residual surface stress to predetermined disc portions to enhance resistance to cracking.

摘要： A plural cavity toroidal transmission is designed to permit transmission of great torque between output side disks and a sleeve while maintaining a thickness of the sleeve. To this end, convex portions are formed on outer surfaces of the output side disks and concave portions are formed on edge portions of both axial ends of the sleeve. By fitting the convex portions into the concave portions, synchronous rotations of the pair of output side disks and transmission of rotation from the output side disks to an output gear can be achieved.

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 canceled 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： 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.
