Embodiment

[0033] As shown in Figure 1, the motor 2 provides a speed of 0-5000r / min, drives the main shaft 8 to rotate through the coupling 3, and the speed is regulated by the frequency converter 1. The two ends of the main shaft 8 are supported by the bearing 4 and the tested bearing 5, and the bearing 4 and the tested bearing 5 are installed in the coaxial hole of the box 9; the load 6 is generated by the load controller 7 and applied to the center or both sides of the main shaft 8. On the side, the stiffness (deformation) of the main shaft and the influence of dynamics on the sliding bearing are generated. The load can be static load or dynamic load. The load is controlled by the computer, and the size and frequency of the change can be randomly changed; the lubricating oil is supplied by the electric pump Station supply, the lubricating oil passes through the oil supply pump of the electric pump station, then injects into the bearing through the oil supply hole of the bearing, and th...

Abstract

A test ¿C bed of multifunction sliding bearing is composed of mechanical driving unit including motor driving main shaft being supported by bearing and tested bearing at its two ends and being exerted load on main shaft center through load controller as well as being set with lubricant oil circulation loop; signal test system including transducer, secondary instrument and data collecting ¿C analyzing ¿C displaying unit for measuring and calculating performance parameter of sliding bearing at any moment and for displaying quantitative result in graphic form.

Description

Technical field: [0001] The present invention relates to a sliding bearing test stand, more specifically a sliding bearing test stand which regards a shaft and a bearing as a system and can quantitatively display the interaction between different mechanical behaviors, especially the stiffness (deformation) of the shaft and the relationship between dynamic effects and A test rig for the interaction between lubrication properties of plain bearings. Background technique: [0002] Sliding bearings are the most common and basic support-transmission system components used in various mechanical devices, which have a direct impact on the working conditions, reliability and durability of mechanical devices. Through the test of sliding bearings, the performance of sliding bearings can be tested and evaluated under actual working conditions, and the influence of various factors can be studied. [0003] Existing sliding bearing test benches generally only test a single part of the slid...
