PLANETARY TRACTION ROLLER TRANSMISSION
Document Type and Number:
Japanese Patent JPH0754949
Kind Code:
A
Abstract:
PURPOSE: To provide a planetary transmission having a high transmission ratio, even though it has a compact constitution.
CONSTITUTION: A planetary traction roller 11 has a small diametral part 11a and a large diametral part 11b. The small diametral part 11a is rolled on a traction ring 10 fixed on a housing 1 and a sun roller structure 8 fixed on an output shaft 3, and the large diameter part 11b is rolled on a second traction ring 17 connected to an output shaft 4. Therefore, the output shaft 4 is rotated at a low speed, matched to different diameters of both the small and large diametral parts 11a, 11b.
