AI Technical Summary

Problems solved by technology

At present, the domestic high-precision reducer detection system generally adopts a horizontal structure in which multi-level components are arranged in series. The detected torque of the reducer can reach thousands of Newton meters. The high torque requirement brings great challenges to the detection of the reducer. The detection equipment will be distorted and deformed under the influence of large torque, which seriously affects the detection accuracy

In the case of high torque and high speed, the structural rigidity of the detection equipment is insufficient, the deformation error is easy to be transmitted, superimposed and even amplified, and the deformation is introduced into the detection result. An effective method has not yet been proposed to solve this problem.
