For the ease of it will be appreciated by those skilled in the art that, by output shaft, be that forward, zero output and output shaft are that principle explanation is carried out in reverse three aspects below, first, suppose that gear ring 34 and the transmission velocity ratio of feedback gear 4 are 2:1.
1. when output shaft output state need to be for forward, by regulating speed governing assembly, make to be around in drive belt ring in the circular groove between driving wheel standing part and driving wheel active part and be greater than drive belt ring in the circular groove being around between follower standing part and follower active part around diameter around diameter, both, by speed governing assembly, make the rotating ratio between input shaft and rotating shaft be greater than at 1 o'clock, input bevel gear rotating speed is less than by rotating shaft, the gear ring rotating speed that feedback gear is controlled, by bevel planet gear, be passed to the sense of rotation of output bevel gear thus contrary, output shaft is forward output.
2. when output shaft output state need to be when reverse, by regulating speed governing assembly, make to be around in drive belt ring in the circular groove between driving wheel standing part and driving wheel active part and be less than drive belt ring in the circular groove being around between follower standing part and follower active part around diameter around diameter, both, by speed governing assembly, make the rotating ratio between input shaft and rotating shaft be less than at 1 o'clock, input bevel gear rotating speed is greater than by rotating shaft, the gear ring rotating speed that feedback gear is controlled, by bevel planet gear, be passed to the sense of rotation of output bevel gear thus contrary, output shaft is oppositely output.
3. when output shaft output state is zero, when both output shaft is no-output state of rest, by regulating speed governing assembly, make to be around in drive belt ring in the circular groove between driving wheel standing part and driving wheel active part and equal to be around in drive belt ring in the circular groove between follower standing part and follower active part around diameter around diameter, both, by speed governing assembly, make the rotating ratio between input shaft and rotating shaft equal at 1 o'clock, input bevel gear rotating speed equals by rotating shaft, the gear ring rotating speed that feedback gear is controlled, the power that is passed to output bevel gear by bevel planet gear is thus zero, output shaft no-output state.
