Title:
REVOLUTION ANGLE REDUCING APPARATUS
Document Type and Number:
Japanese Patent JPS5969564
Kind Code:
A
Abstract:
PURPOSE:To obtain a revolution angle reducing apparatus for reducing the revolution angle in a large reduction rate to the infinite by the combination of arranged an inner ring, outer ring, and an intermediate ring and a plurality of planetary rolling bodies. CONSTITUTION:A plurality of planetary rolling bodies 3... are attached in rolling onto the outer periphery of an inner ring 1 and the inner periphery of an outer ring 2 fixed onto a housing, including the inner ring 1, outer ring 2, and an intermediate ring 4. Other parts of the planetary rolling body 3 are attached in rolling onto the inner periphery of the intermediate ring 4. In this case, the rolling contact radius r32 of the planetary rolling body 3 with the outer ring 2 and the rolling contact radius r34 of the planetary rolling body 3 with the intermediate ring 4 are set a little different each other. The inner ring 1, planetary rolling body 3, outer ring 2, and the intermediate ring 4 are fitted in a degree in which a little elastic deformation is formed in the mutaul contact part through the cooling fitting method for the inner ring 1. Thus, an apparatus which possesses a large revolution-angle reduction ration and is free from backlash can be obtained.
