Title:
FRICTION ROLLER TYPE SPEED CHANGE GEAR
Document Type and Number:
Japanese Patent JPH11336864
Kind Code:
A
Abstract:
To make this speed change gear small in size, and actualize a structure capable of obtaining a high transmission efficiency regardless of abrasion and change in temperature.
An inner wheel 41 the outer circumferential surface of which is formed into a conical projected surface, is fixed to the end part of an input shaft 27. Each conical shaped transmission roller 47 is held in between the outer circumferential surface of the inner wheel 41 and the inner circumferential surface of an outer wheel 49 respectively. A carrier 45 supporting a pivot shaft 46 in which these transmission rollers 47 are pivoted, is combined with an output shaft 28. In addition, a disc spring 52 is provided for a space between the outer wheel 49 and a holder 29.
