  • Publication number: 20020139206
    Abstract: A positive/reverse rotation control device comprises a shaft and at least two one-way bearings, wherein the shaft pierces simultaneously through axial apertures of the two bearing, and the two one-way bearings are mounted in opposite directions. Thus, with the shaft rotating positively (e.g., clockwise), the first bearing is to rotate positively (clockwise), and the gear assembly or tooth gage belt pivotally jointed to the first one-way bearing is to be brought to work, whereas the second one-way bearing stays still; when the shaft rotates reversely (e.g., counter clockwise), the second one-way bearing is then to be brought to rotate reversely (counter clockwise), and thus bringing the gear assembly or tooth gage belt pivotally connected to the second one-way bearing to work, whereas the first one-way bearing stays still.
