The invention, which belongs to the technical field of winches, discloses a force reduction performance test board for a friction wheel type winch force reduction mechanism. The force reduction performance test board mainly comprises a torsion limiter, a cable, a first winding drum, a first guide wheel, a liquid storage tank, a fourth guide wheel, a second winding drum, a first torsion sensor, a first reduction gearbox, a first motor, a second torsion sensor, a second reduction gearbox, a second motor, a test bench, a first fixing plate, a third guide wheel, a driven friction wheel, a drivingfriction wheel, a first transition gear, a main driving gear, a second fixing plate and a second guide wheel. During testing, one end of the cable is wound and fixed on the first winding drum; the other end of the cable sequentially winds around the first guide wheel, the second guide wheel, the driving friction wheel, the driven friction wheel, the third guide wheel and the fourth guide wheel andthen the cable is wound and fixed on the second winding drum. Therefore, the force reducing performance of the cable and the friction wheel is tested in gas and liquid environments, and an optimal friction wheel and cable combination form can be provided for winches under different working conditions according to a test result.
Description
technical field [0001] The invention belongs to the technical field of winches, and in particular relates to a force reduction performance testing platform of a friction wheel type winch force reduction mechanism. Background technique [0002] Winches are often used in conjunction with cables or steel cables to achieve lifting of objects. In order to meet the lifting requirements of large loads under the premise of miniaturization and light weight of the winch, a force reduction mechanism is usually designed and installed inside the winch, so that the force reduction mechanism is mainly used to bear large loads, while other parts of the winch are more stressed. Small. In recent years, with the increasing demand for deep sea, polar and extraterrestrial exploration, the friction wheel winch force reduction mechanism has been widely used. The friction wheel type winch force reduction mechanism is to wind the cable on the friction wheel. When the friction wheel drives the cabl...
