Problems solved by technology

The above methods can realize the test of the relationship between the thrust and torque of the screw pair, but the strain gauge test method generally relies on manually pasting the strain gauge, which is easily affected by subjective factors and the efficiency is relatively low; the ultrasonic test method has special effects on the structure and processing of the test piece. The requirements and limitations are relatively large; the cost of purchasing test equipment for the torsion sensor test method is very high

Abstract

The invention relates to a screw pair thrust-torque relationship testing device for a tensile testing machine, and belongs to the technical field of testing. The tensile force of a counterweight is ingeniously converted into the torque output of a screw pair by virtue of structures such as a rotating disk, a pulley and a steel wire rope, so that the device is simple in structure and low in construction cost; a thrust-torque relationship of the screw pair in the whole lead is conveniently tested by virtue of the tensile testing machine, particularly whole-lead thrust under specified output torque can be conveniently tested, and the device is easy to operate and convenient to measure.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a device for testing the relationship between thrust and torque of a screw pair for a tensile testing machine. Background technique [0002] The screw pair is composed of a screw sleeve and a screw shaft, which can convert the input thrust into torque output. Although the relationship between thrust and torque can be obtained through theoretical calculation, due to the influence of factors such as friction loss and manufacturing errors, there are often large differences between theoretical calculation results and actual conditions. In order to obtain the actual relationship between the thrust and torque of the screw pair and test the reliability of the theoretical calculation results, it is necessary to conduct actual tests on the screw pair. The current testing methods mainly include strain gauge testing, ultrasonic testing, and torsion-tension sensor testing. The above methods...
