AI Technical Summary
Existing technologies lack effective methods for testing the frictional torque of universal joints, especially high-precision universal joints (frictional torque less than 4.5 gf·cm), which makes it impossible to effectively understand their precision and limits the manufacturing of high-precision universal joints.
The friction torque of the two shafts of the tie rod universal joint is tested using a testing device. This includes clamping the tie rod universal joint onto the testing device, testing the friction torque of the X and Y shafts, and conducting a comprehensive test using a shaft switcher and an angle adjustment mechanism. The test results are then output, and finally the tie rod universal joint is unloaded from the device.
This technology enables comprehensive and effective testing of the friction torque of the tie rod universal joint, improving manufacturing efficiency and ensuring the accuracy and comprehensiveness of the test.
