It is fixedly connected and is integrated with output shaft 15.
Third connects key axis 9 and first and connects the coaxial arrangement of key axis 1, and is fixedly connected with the first internal gear 8, when the first internal gear
8 when reduction of speed is twice in succession with lower rotation speed operation, drives third external gear 12 by third eccentric bushing 10 and 3rd bearing 11, the
Three external gears 12 because fixed and cantilever installation third pin shaft 13 restriction effect due to cannot make continuous rotation movement, be only capable of making
Ring pendular motion just drives the third internal gear 14 of its periphery to make continuous rotation movement when third external gear 12 makees ring pendular motion, real
Now third time retarded motion, the output shaft 15 being integrated that is fixedly connected at this time with third internal gear 14 obtain low-down revolving speed,
This gear continuously for several times after decreasing transmission, obtains very big transmission speed ratio with axial built-up gear by radial.
When being power intake with output shaft 15, first, which will connect key axis 1, continuously three times after speedup, to obtain very big
Speed increasing ratio, first, which connects key axis 1, will export higher rotation speed movement.
