Title:
DIFFERENTIAL TYPE PLANETARY ROLLER POWER TRANSMISSION
Document Type and Number:
Japanese Patent JP3459946
Kind Code:
B2
Abstract:

PURPOSE: To prevent skew of planetary rollers and to maintain a constant output rotation speed in the differential structure which can reduce dimension in the axial direction.
CONSTITUTION: Two sets of three planetary rollers 4 and 5 are arranged adjacent to each other in the axial direction, and each of the planetary roller groups 4 and 5 are supported by a single carrier 8 so that they are rotated synchronously to constitute a planetary roller type power transmission with the differential structure. As individual dimension in the axial direction of the planetary rollers 4 and 5 can be small and each of the planetary rollers 4 and 5 making a pair with two rollers is rotated synchronously, skew is hard to occur.
