Background
The flexible shaft is a shaft with small rigidity, elasticity and free bending transmission, and is mainly used for connecting two shafts which are not on the same axis and in the same direction or have relative motion so as to transmit rotary motion and torque. In the field of automobiles or other mechanical devices, flexible shafts are often used to transmit torque for flexibly transmitting rotational motion to any location.
The torque of the flexible shaft is a core index of the performance of the flexible shaft, the conventional method for testing the torque of the flexible shaft adopts a three-jaw chuck to clamp two ends of a jaw product, one end of the chuck is fixed, the other end of the chuck can rotate freely, a torque wrench is used for twisting the freely rotatable chuck in the testing process to rotate and drive one end of the flexible shaft to twist until the flexible shaft is completely broken, and the measured force is the breaking torque of the flexible shaft.
Although the above described test methods can yield test results, there are several significant drawbacks. One is to use torque wrench as power to drive the flexible axle wrench in the test operation process, when the flexible axle breaks suddenly, the spanner can produce the shake under the inertia effect, and then leads to torque wrench pointer to slide, directly influence the test result under the inertia effect. Secondly, when the large-diameter flexible shaft is tested, the operation is difficult to be turned only by manpower, and a very serious safety accident can be caused once the torque wrench falls off from the hand of an operator in midway.
In summary, how to provide a brand-new tooling device for testing a flexible shaft, which improves the safety of the testing process while ensuring the accuracy of the testing result, becomes a problem to be solved urgently by the technical staff in the field.
