Publication number: 20160178036Abstract: A hydraulic pressing unit for pressing an input disc in an axial direction includes a first hydraulic pressure chamber and a second hydraulic pressure chamber, a primary piston facing the first hydraulic pressure chamber and a secondary piston facing the second hydraulic pressure chamber, and oil holes configured to supply oil into the first hydraulic pressure chamber are formed in an input shaft, while oil paths configured to supply oil into the second hydraulic pressure chamber are formed in the secondary piston. Consequently, a separate oil hole configured to supply oil into the second hydraulic pressure chamber is not formed in the input shaft. Thus, it is possible to mitigate the cost and labor hours involved in fabrication of the input shaft. Two oil holes spaced apart from each other in an axial direction do not exist in the input shaft.Type: ApplicationFiled: July 17, 2014Publication date: June 23, 2016Applicant: NSK LTD.Inventors: Masahiro KITA, Yasunori OISHI, Hiroki NISHII

Patent number: 9188206Abstract: 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.Type: GrantFiled: June 5, 2008Date of Patent: November 17, 2015Assignee: NSK LTD.Inventors: Hiroki Nishii, Takashi Imanishi

Patent number: 9080652Abstract: 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).Type: GrantFiled: February 10, 2012Date of Patent: July 14, 2015Assignee: NSK LTD.Inventors: Toshiro Toyoda, Hiroki Nishii
