Abstract

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.

Description

technical field [0001] The invention relates to a shafting measurement technology, in particular to a precision shafting dynamic torque measuring instrument. Background technique [0002] Shafting friction torque is a technical index to comprehensively evaluate the dynamic performance of shafting. At present, there is no shafting friction torque testing equipment in China. Most of them measure the friction torque value of each supporting bearing before installation, and then estimate the total friction torque of the shafting components according to the measured value of the supporting bearing friction torque. The friction torque value measured by this method does not take into account the installation error of the connecting parts of the shaft system, so there is a large error in the obtained shaft friction torque. Contents of the invention [0003] The invention provides a precision shafting dynamic torque measuring instrument for measuring the shafting friction torque i...
