Title:
PLANETARY ROLLER MECHANISM
Document Type and Number:
Japanese Patent JP2010276131
Kind Code:
A
Abstract:
To restrain a transmission torque variation and vibration in a planetary roller mechanism.
In the number P of pinion rollers 23 juxtaposed along the peripheral direction and the number C of cam rollers 30 juxtaposed along the peripheral direction, P≠C/k and P≠k×C are realized to optional 1 or more of integer k, and 2 or more of common divisor also exists in P and C. Thus, even if the relatively positional relationship is changed between the respective pinion rollers 23 and the respective cam rollers 30 in the peripheral direction, both the scalar sum and the vector sum of pressing force of the respective pinion rollers 23 are not varied.
