The invention belongs to the field of helicopter main reducer ground simulation tests, and particularly relates to a helicopter main reducer rotor torque static calibration method applied to high-power and high-torque test equipment. A main speed reducer is fixed on the ground through a bolt, an engine input shaft is fixed through a fixing support, a tail output shaft is fixed through a fixing support, two torsion bars are installed on a calibrated torque meter, and pulling force can be applied to one ends of the torsion bars by adjusting hexagonal adjusting nuts. The pulling force is changed by controlling the adjusting force of the hexagonal adjusting nut. The function of the device can meet the requirement for static calibration of the rotor torque of the main speed reducer, and the device has the advantages of being easy to operate and high in reliability.

    本发明属于直升机主减速器地面模拟试验领域,具体涉及一种应用在具有大功率、高扭矩的试验设备上的直升机主减速器旋翼扭矩静态标定方法。本发明将主减速器通过螺栓固定于地面上,通过固定支架将发动机输入轴固定,通过固定支架将尾输出轴固定,将两根扭力杆安装于被标定扭矩仪上,通过调节六方调节螺母可以对扭力杆一端施加拉力,控制六方调节螺母的调整力度改变拉力大小。本发明所具备的功能可满足主减速器旋翼扭矩静态标定的需求,具有操作简单可靠性高的特点。
