Abstract

The invention discloses a testbed of mixed loading servo drive system reliability. The testbed solves the problems that a loading mode in the prior art is simple and cannot reflect the actual working conditions of a servo drive system. The testbed comprises a servo motor supporting part, an inertia loading part, a torque loading part, a vibration temperature-humidity loading part and an automatic control part. The servo motor supporting part is arranged on the left side of a horizontal iron (1), the inertia loading part is arranged on the position, on the right side of the servo motor supporting part, of the horizontal iron (1), and the torque loading part is arranged on the position, on the right side of the inertia loading part, of the horizontal iron (1). A servo motor (11) to be tested is connected with a left-end coupling of a stepped shaft (8) of the inertia loading part, the right end of the stepped shaft (8) of the inertia loading part is connected with an output shaft coupling of a dynamometer machine (2) of the torque loading part, and the RS-232C port of the vibration temperature-humidity loading part is connected with the RS-232C port of an industrial personal computer (13) of the automatic control part through wires.

Description

technical field [0001] The invention relates to a test device applied to the reliability of a servo drive system, more precisely, the invention relates to a reliability test bench for a mixed-loaded servo drive system which realizes inertia and torque loading on the servo drive system and conducts reliability tests . Background technique [0002] The development of numerical control technology has created opportunities for the take-off of the manufacturing industry. The performance and number of use of numerical control machine tools are important standards for measuring a country's industrial development. my country is now a big country in the production and use of CNC machine tools. The developed CNC machine tools have made great progress in terms of precision, speed, and multi-axis linkage control. However, the main component of CNC machine tools—the servo drive system, its performance and reliability There is still a certain gap between the performance level and the inte...
