Abstract:

To provide a transmission preventing roller partial wear and the deterioration of maximum transmission torque caused by the bending of a driven roller shaft even if a low side gear ratio wherein transmission torque becomes large is selected.

Three driving rollers 11, 12 and 13 with different roller diameters are set as driving rollers 1, and three driven rollers 21, 22 and 23 with different roller diameters are set as driven rollers 2. The driven rollers 21, 22 and 23 are set on an eccentric driven roller shaft 24 with both ends arranged in a first support bearing 3 and a second support bearing 4, and a plurality of roller pairs set with different gear ratios can be changed over. Of the plurality of roller pairs, no other roller pair is arranged between a first gear roller pair 11 and 21 with the largest gear ratio, and the first support bearing 3 close to the first gear roller pair 11 and 12, and no other roller pair is arranged between a second gear roller pair 12 and 22 with the second largest gear ratio, and the second support bearing 4 close to the second gear roller pair 12 and 22.
