Title: Power transmission device
Inventor: IRITANI MASANORI
IPC: F16H15/38
Filed: 2001-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a power transmission device to perform power transmission through a rolling contact of a troidal type CVT (a transmission with continuously variable gear ratio) in which the durability is enhanced. SOLUTION: The power transmission device includes a roller 16 which makes rolling contact both with an input and an output discs for performing power transmission between the two discs. The surface 22 of the roller 16 confronting the two discs has a contacting part 26 which contacts actually with the input and output discs for performing power transmission. The width B of the surface 24 exceeds three times as large as the width 2b of the contacting part 26. This lessens the influence of the end face upon the internal shearing stress generated in the neighnourhodd of the contacting part to drop the stress. This drop of the stress lessens the amount of heat emission. The heat capacity of the roller 16 can be made greater by enlarging the width B of the confronting surface, and also the area of heat emission is widened.  The drop of stress and the drop in temperature result in enhancement of the durability.
