Problems solved by technology
However, at present, no unit or individual has developed a device capable of testing the performance characteristics of flexible shafts, so it is impossible to quantitatively test the performance characteristics of various flexible shafts.
This has caused great inconvenience to designers, testers, and users of flexible shafts, which not only limits the design, selection, and improvement of flexible shafts, but also is not conducive to the promotion and application of flexible shafts.

The invention discloses a flexible shaft performance characteristic testing device comprising a front test stand, a rear test stand, a control box and a computer. The front test stand and the rear test stand are respectively connected with two ends of a flexible shaft. The front test stand and the rear test stand are coordinated to twist the flexible shaft, and torques before and after twisting are measured. The control box controls experiment conditions of the front test stand and the rear test stand. The computer acquires experiment data from the front test stand and the rear test stand, and the data are processed. Compared with testing devices in the prior art, the flexible shaft performance characteristic testing device adopts modularization design so that quantitative tests of various flexible shaft performance characteristics are realized, and reference basis is provided for designing, manufacturing and application of the flexible shaft.
Description
technical field [0001] The invention relates to a performance test of a flexible shaft, and more specifically, the invention relates to a device for testing the performance characteristics of a flexible shaft. Background technique [0002] The flexible shaft is made by winding several layers of steel wire alternately on a mandrel. Its performance requirements are to be able to bend in any direction within a considerable range and transmit torque. Performance parameters such as turning radius, ultimate strength and service life are all important performance parameters of flexible shafts. However, at present, no unit or individual has developed a device capable of testing the performance characteristics of flexible shafts, so it is impossible to perform quantitative tests on the performance characteristics of various flexible shafts. This has caused great inconvenience to the designers, testers and users of the flexible shaft, which not only limits the design, selection and i...
