Document Type and Number:
Japanese Patent JP3735297
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To be able to prevent lowering of transmitting force for transmitting motive power and damage of a planet roller.
SOLUTION: There is provided a planet roller type traction drive device such structured as follows. There are provided a casing, a solar roller and a plurality of planet rollers arranged adjacently to an external periphery of the solar roller. The planet rollers are rotatable around axes of these planet rollers for the respective planet rollers, which are fixed to the casing. Further, there are provided a ring roller adjacent to a plurality of the planet rollers and including collar portions involving these planet rollers with these planet rollers being pressed thereby. The ring roller includes a disc portion from whose outer peripheral portion the collar portion of the ring roller extends, and a second axis extending from the center of the disc. Furthermore, there is provided at least one recess portion formed symmetrically around the center of the disc portion of the ring roller. One O-ring may be arranged in a concave portion formed in an internal peripheral surface of the outer ring contacting a bearing of the planet rollers. A seal member may be provided between an input shaft and a traction portion.
