Document Type and Number:
Japanese Patent JP3632358
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide the structure, which has excellent transmitting efficiency and of which assembling work is facilitated.
SOLUTION: This transmission comprises a center roller 9a, of which peripheral surface is formed as a first cylindrical surface 10b, and an outer ring 11, of which inner peripheral surface is formed as a second cylindrical surface 13b, are eccentrically arranged with each other. Width of an annular space 14b between the first cylindrical surface 10b and the second cylindrical surface 13b are formed uneven over the circumferential direction. Guide rollers 32a, 32b, which are supported by fixed pivotal shafts 15a, 15a freely to be turned, and a wedge roller 31c supported by a pivotal shaft 15b, which can be freely displaced, are provided in the annular space 14b. In the condition that the wedge roller 31c is moved to a wide width part of the annular space 14, the center roller 9a is inserted into each roller 31c, 32a, 32b. After the insertion, the wedge roller 31c is moved to a narrow width part of the annular space 14b.
