Speed-changing system utilizing one-way drive characteristics of one-way bearings

Abstract

The invention relates to a speed-changing system utilizing one-way drive characteristics of one-way bearings, comprising a driving shaft and a driven shaft. The driving shaft is provided with a first one-way bearing and a second one-way bearing, and the first one-way bearing and the second one-way bearing are arranged in opposite directions; the outer ring of the first one-way bearing is provided with a driving gear for a planetary speed reducing mechanism; the driving gear is meshed with a plurality of idle gears, and the idle gears are meshed with a sleeve which is provided with an inner ring gear; the outer ring of the second one-way bearing is provided with the driven shaft, and the driven shaft is provided with a third one-way bearing; the outer ring of the third one-way bearing is jointed with the inner wall of the sleeve; and the third one-way bearing and the first one-way bearing are arranged in the same direction. When rotating positively, the driving shaft can drive the driven shaft to rotate positively at the same speed, and when rotating negatively, the driving shaft can still drive the driven shaft to rotate positively, but the rotating speed ratio of the driving shaft to the driven shaft is equal to the speed reducing ratio of the driving shaft to a planetary reducing speed mechanism, thus the purpose of changing speed in the same direction is achieved.
