Title:
PLANETARY ROLLER REDUCTION GEAR
Document Type and Number:
Japanese Patent JP2009209959
Kind Code:
A
Abstract:
To provide a planetary roller reduction gear in which sliding abrasion by deformation of an inner roller in driving rotation is reduced or eliminated, and transmission friction loss is reduced.
A plurality of holes 11a and 4a are oppositely arranged on one side or both sides of a casing 11 and to the inner roller 4, respectively. A plurality of rotation preventive pins 17 are inserted into the holes, and rotation of the roller 4 is prevented by being matched with the casing 11, by being loosely joined to the inner roller 4, or by being loosely joined to the casing 11 and by being matched with the inner roller 4.
