Title:
PLANETARY SPEED CHANGE DEVICE
Document Type and Number:
Japanese Patent JPS5828041
Kind Code:
A
Abstract:
PURPOSE:To easily maintain a state of rotary directional contact under pressure almost to constant among a center wheel, outer wheel and planetary rollers, by elastically deforming the cylindrical planetary rollers thermselves and press fitting said rollers between the center wheel and the outer wheel. CONSTITUTION:A center wheel 6 is fitted by a spline to the end part of an input shaft 2, while an outer wheel 7 is secured to a fixed case in a concentrical state with the center wheel, and a plural number of thin thickness cylindrical rollers 8 of diameter, slightly larger than a distance between the both wheels 6, 7 in a free condition, are interposed at a suitable distance apart rotary directionally between the center wheel 6 and the outer wheel 7. Then cylindrical supporting shafts 10 of diameter, smaller than an internal diameter of the roller 8, are mounted through bolts 11 to peripherally plural places of a rotary unit 9, fitted by a spline to the end part of an output shaft 2, and the roller 8 is rotatably supported to said cylindrical supporting shaft 10.
