Problems solved by technology

[0003] The on-load test of the steering gear is usually tested with an expensive torque tester, which requires a certain amount of personnel to operate accurately, which is costly and cumbersome; similarly, in order to complete the precision calibration of the steering gear, usually in the design of the steering gear components Among them, it carries an expensive high-precision sensor itself. The high-precision sensor has a high cost and cannot effectively verify and screen its true accuracy.

Abstract

The invention relates to a device for on-load testing and accuracy calibration of steering engine component, and belongs to the technical field of high-precision steering engine testing. On the basisof the steering engine component and a substrate, the on-load testing part is coaxially connected with the output shaft of the one-way steering engine to test the rated load of the steering engine successfully; the precision calibration part is coaxially connected with the output shaft of the side one-way steering engine and achieves high coaxial precision, high-precision transmission angle and torque, so that the precision calibration of the steering engine is realized; the whole device can simultaneously realize the on-load testing and precision calibration of the steering engine component,has the advantages of simple structure, high integration level and convenient operation.

Description

technical field [0001] The invention relates to a device for on-load testing and precision calibration of steering gear components, belonging to the technical field of high-precision steering gear testing. Background technique [0002] The steering gear is a position or angle servo drive, suitable for those control systems that require constant changes in angle and can be maintained. The load test is a key experiment for the driving performance of the steering gear. By loading the rated external load on the output shaft of the steering gear, and driving the steering gear to work normally for a certain period of time, and observing its load operation, the driving of the steering gear can be tested. performance. Accuracy calibration is another key experiment for the control accuracy of the steering gear. The control accuracy of the steering gear is calibrated by measuring the position error of the steering gear under normal operation. [0003] The on-load test of the steerin...
