Abstract

PURPOSE: To easily switch between reduction gear and direct-coupled turning by arranging the groups of three circular rollers in a row and also inserting a subroller between an elliptical input shaft and an eccentric drum capable of braking eccentrically to the input shaft.
CONSTITUTION: When a brake 14 is released for an eccentric drum consisting of a drum 3 and eccentric rings 6 and 7 attached to the drum 3 by biasing the center of the curvature radius of the inside circumferences 4 and 5 through 180°, an input shaft 1 and the eccentric drum turn integrally through rollers 8 and 9, and output shaft 10 turns in directly coupled manner with the input shaft 1. When the turning of the eccentric drum is stopped by the brake 14, the rollers 8 and 9 are gradually moved in one direction by the rotation of the input shaft 1, and correspondingly a subroller 11 turns with the same speed as the rollers 8 and 9. Thus, the deduction of speed with a reduction ratio of 1/1.5 can be attained.
