Reconfigurable lead screw pair and guide rail pair accelerated life electro-hydraulic servo test bench

Abstract

The invention provides a reconfigurable lead screw pair and guide rail pair accelerated life electro-hydraulic servo test bench which is characterized in that two lead screw bearing seats of a T-shaped table between two guide rail mounting tables on a base are provided with lead screws connected with a motor; guide rails on the guide rail mounting tables are matched with guide rail sliding blocks; guide rail sliding block backing plates on the guide rails, a grating bar reading head on one guide rail mounting table and nut bases on the nuts of the lead screws are connected with the bottom of a stressed sliding table; one side of the stressed sliding table is meshed with a gear at the end part of the output shaft of a magnetic powder brake through a gear rack; the other side face of the stressed sliding table is opposite to a force application wheel of a transverse loading mechanism; and the upper part of the stressed sliding table is opposite to a force application wheel of a vertical loading mechanism. The test bench provided by the invention can be used for realizing the accelerated life test of three-way dynamic loading of multiple types of lead screw pairs and guide rail pairs, collecting test data required for evaluating the residual lives and degradation mechanisms of the lead screw pairs and the guide rail pairs in real time, and providing more reliable test basis for the design and maintenance of the lead screw pairs and the guide rail pairs.

Description

technical field [0001] The invention relates to a reconfigurable lead screw pair and guide rail pair accelerated life electro-hydraulic servo test bench. Background technique [0002] The lead screw pair refers to the screw transmission part composed of the lead screw and the nut, and the guide rail pair refers to the motion pair composed of the guide rail and the guide rail slider. Screw pair and guide rail pair are commonly used transmission components in mechanical systems and are widely used in various machinery and equipment. Therefore, real-time monitoring and evaluation of the performance degradation status and remaining life of the screw pair and guide rail pair is conducive to establishing a reasonable and effective maintenance plan, reducing unnecessary downtime and saving a lot of maintenance costs. [0003] At present, there are few test technologies and equipment for the performance degradation state and life prediction of screw pairs and guide rail pairs at ho...
