摘要：A positive/rever rotation control device compris 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., clockwi), the first bearing is to rotate positively
(clockwi), and the gear asmbly or tooth gage belt pivotally jointed to the first one-way bearing is to be brought to work, whereas the cond one-way bearing stays still; when the shaft rotates reverly (e.g., counter clockwi), the cond one-way bearing is then to be brought to rotate reverly (counter clockwi), and thus bringing the gear asmbly or tooth gage belt pivotally connected to the cond one-way bearing to work, whereas the first one-way bearing stays still. Such device can be applied to all kinds of machines or equipment, with only a motor being the driving power, and the ur can control the motor by outputting the electrical current in the positive and rever direction to activate respectively the positive and rever one-way bearings to work, thus preventing the idleness and waste of space where more than one motor are to occupy, and effectively lowering the cost.
