Document Type and Number:
Japanese Patent JP7207628
Kind Code:
B2
Abstract:
This transmission in which an output shaft is rotated at a speed different from that of an input shaft is provided with a first rotation mechanism and a second rotation mechanism. The first rotation mechanism has a sun roller rotating integrally with the input shaft, a plurality of planetary rollers which rotate as the sun roller rotates, a planetary roller support section which rotates about a center axis as the plurality of planetary rollers revolve, and a rotation transmitting shaft which rotates about the center axis with the planetary roller support section. The second rotation mechanism has a sun gear which rotates integrally with the rotation transmitting shaft, a plurality of planetary gears which mesh with the sun gear, and a planetary gear support section which rotates about the center axis as the plurality of planetary gears revolve. The output shaft rotates about the center axis with the planetary gear support section. The transmission is further provided with a pressure regulation mechanism which presses radially inward the plurality of planetary rollers according to a load in the rotational direction of the output shaft.
