Embodiment Construction

[0012] Such as figure 1 As shown, the present invention includes a screw 1, a gasket 2, an inner sleeve 3, an outer sleeve 4, a flange bolt 5, a flange plate 6, a rotating body 7, a nut 8, a key 9, a rotating shaft 10, and an axial stopper 11. Battery 12, wireless torque node 13, resistance strain gauge 14, wireless gateway 15, computer 16.

[0013] The rotator 7 is installed on the inner sleeve 3, and there is a clearance fit between them. There is a gap between the inner sleeve 3 and the outer sleeve 4, and the flange 6 is welded and fixed on the outer sleeve 4 and the inner sleeve 3. Together; the screw 1 is fixedly connected with the rotating shaft 10 through the gasket 2 to prevent the inner sleeve 3 from coming out of the shaft end, and the axial stopper 11 prevents the inner sleeve 3 from moving to the other end of the shaft; the flange bolt 5 and the nut 8 rotate The body 7 is fixedly connected with the flange 6; the inner sleeve 3 and the rotating shaft 10 are connec...

Abstract

The invention discloses a dynamic torque test device for a rotating shaft. The dynamic torque test device comprises a catch bolt, a retainer mat, an inner sleeve, an outer sleeve, a flange bolt, a flange disk, a rotating body, a key, a rotating shaft, a wireless torque node and a resistance strain foil. When the torque of the rotating shaft is measured, the phenomenon that the torque of the rotating shaft is measured by cutting off the rotating shaft and connecting two cut shafts by a torque sensor is avoided; during measurement of the torque, damage to the rotating shaft is avoided, the mounting space is small, the manufacturing cost is low, and the measurement precision is high.

Description

technical field [0001] The invention relates to a torque testing method, in particular to a testing device for rotating shaft torque. Background technique [0002] Torque is an important working parameter of rotating power machinery, and torque measurement has become an important part of mechanical quantity measurement. If the average, instantaneous and peak torque value, speed and power of the tested machine can be measured accurately, reliably and conveniently, it will be beneficial to improve and enhance the performance of the mechanical parts. Torque can be divided into two categories, static torque and dynamic torque. Due to the acceleration during power input, the rotating body for dynamic torque measurement generally produces relative motion, so the overall design has higher requirements for lead wires, signal processing and mechanical connection methods. [0003] The traditional method is to cut off the rotating shaft on which the rotating body is installed, and th...
