Zusammenfassung:A precise shaft dynamic torque measuring instrument relates to a shaft measurement technology and solves the problem that shaft friction torque can not be accurately measured and the test scope is small. The precise shaft dynamic torque measuring instrument comprises a structure adjusting subsystem, a pitching and yaw detection shaft subsystem, a positioning installation subsystem, a lateral roller detection shaft subsystem and a support and detection platform subsystem and measures friction torque of a fake load on vertical shaft direction. A torque motor drives a torque sensor to rotate through a toothed shaft, the displacement is adjusted on the vertical and horizontal direction, and a handwheel is rotated to move a leading screw nut mechanism vertically or horizontally along a linear guide rail. A rotary table drives a vertical sliding bench fixed together with a connection board to realize rotation of changing angle at certain level. A counterweight block is added on a fixed pulley on the vertical sliding bench to prevent extra torque, and verticality precision is ensured.
