Title: Toroidal continuously variable transmission
Inventor: NAKANO MASAKI
IPC: F16H15/38
Filed: 1988-02-12
Abstract: PURPOSE:To ensure a space for housing other accessory parts in a casing by supporting a second shaft at the torque delivering portion thereof on a casing side and providing the end of the second shaft on this supporting portion. CONSTITUTION:As torque is transmitted from an input shaft 12 to an input disk 22, a loading cam 30 is operated and a pressing force corresponding to the input torque is applied to the input disk 22 as well as to an input disk 22a via the shaft 12 increasing the pressure contact force of friction members 26, 26a, to prevent the occurrence of slip in each friction members 26, 26a at the time of increasing the input torque. The torque inputted into output disks 24, 24a is collected to a driving gear 44, from which the torque is outputted to a counter shaft (second shaft) 50 via an output gear 48. Since the shaft 50 has a length about half the length of the shaft 12 with its end portion being supported by an intermediate shaft 18, a wide space S can be provided in a casing 14 on a toroidal speed change mechanism 20 side devoid of the shortened shaft 50.

Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To provide an NC machine tool working data generating method capable of removing uneveness in the working accuracy of a formed part after working and forming a highly accurate worked surface. SOLUTION: In the case of forming a three-dimensional(3D) face by using an NC machine tool, a tool moving route is provided with plural working tracks 46 between two working range outlines 44, 45.
