  • Publication number: 20130102436
    Abstract: The present invention provides a toroidal continuously variable transmission capable of reducing loss which occurs at a bearing and achieving range-widening at low cost with easy disc machinability. In the toroidal continuously variable transmission, a bearing ring 100 of a ball bearing 6 is formed at a small end surface 3a of an inner disc 3. Further, at least a part of the bearing ring 100 is axially overlapped with a traction surface 12 which is a boundary surface between a power roller and the inner disc 3. Further, a position adjustment member 120 is inserted between support posts 8a, 8b and a bearing ring facing to the disc 3 (the other bearing ring of the ball bearing 6 opposed to the bearing ring 100 of the small end surface 3a).

  • Patent number: 8167760
    Abstract: In this toroidal continuously variable transmission unit, a carrier 100 and a disc 2 is brought into direct friction contact with each other, and power transmission between the carrier 100 and the disc 2 is implemented by friction force. Because of this, the necessity of machining a gear or claw on the disc or carrier, which has conventionally be done, is obviated, whereby a manufacturing process can be shortened and manufacturing costs can largely be reduced.

    Abstract: A toroidal type continuously variable transmission has an input shaft to which a rotation torque is input, an input side disk and an output side disk that are concentrically and rotatably supported by the input shaft in a state that an inner peripheral surface of the input side disk opposes to an inner peripheral surface of the output side disk, a power roller held between the input side disk and the output side disk and a hydraulic loading device applying predetermined pressing force so that the power roller is pressed between the input and output side disks. Fine grooves are formed on at least a radially inner part of the inner peripheral surface of the input side disk and at least radially outer part of the inner peripheral surface of the output side disk, respectively.

  • Publication number: 20080305920
    Abstract: Power roller-side concave grooves are opposed to disk-side concave grooves 19, 19 so as to have angles therebetween in a rolling contact area between a peripheral surface of the power roller and a one-side surface 17 of a disk 16 in an axial direction regardless of a transmission gear ratio of a toroidal continuously variable transmission. Accordingly, the disk-side concave grooves 19, 19 are formed so as to have angles with respect to a circumferential direction of the disk 16 when viewed from a normal direction relative to the one-side surface 17 in the axial direction. Meanwhile, the power roller-side concave grooves are formed into a concentric shape (or a spiral shape) about a central shaft of the power roller. As a result, it is possible to prevent a decrease of a contact area in the rolling contact area regardless of the transmission gear ratio.

  • Patent number: 7384368
    Abstract: A toroidal-type continuously variable transmission includes an input shaft, an input disk and an output disk, plural power rollers, a power roller bearing, an oil passage, and a mesh filter. The input and output disks are supported mutually concentrically with the input shaft and mutually independently rotatably. The plural power rollers are sandwiched between the input disk and the output disks. The power roller bearing rotatably supports the power rollers. The oil passage for leading lubricating oil to the power roller bearing. The mesh filter is provided in the oil passage. Accordingly, the toroidal-type continuously variable transmission can prevent an occurrence of biting-in of foreign substances at a power roller bearing, to thereby increase the life of the power roller bearing.
