Radial sliding bearing test bed with elastic support

Abstract

The invention relates to a radial sliding bearing test bed with an elastic support. The radial sliding bearing test bed with the elastic support is assembled by a test bed base, back-up bearings, a main shaft, a testing bearing, a jet device and a main shaft locating device. The test bed base is used for carrying out location on the back-up bearings and providing lubricating oil channels, the two ends of the main shaft are supported by the back-up bearings, the back-up bearings are angular contact bearings mounted in pairs in a back to back mode, the inner ring and the outer ring of the back-up bearing at the front end of the main shaft are both axially fixed, the inner ring of the back-up bearing at the rear end of the main shaft is axially fixed, and certain axial movement is allowed on the outer ring of the back-up bearing at the rear end of the main shaft. The testing bearing is suspended in the middle of the main shaft and capable of floating up and down, guiding devices are mounted at the two ends of the testing bearing to prevent the testing bearing from deflection without limiting the movement of the testing bearing in the radial plane, an elastic element is mounted outside the testing bearing, and the support stiffness of the testing bearing can be adjusted by changing the stiffness of a spring. Bolt mounting holes are formed in the test bed base, and the test bed can be mounted on a suitable T-shaped groove platform.

Description

technical field [0001] The invention relates to a radial sliding bearing test bench with elastic support. This test bench can carry out experimental research on the characteristics of radial sliding bearings under the condition of elastic foundation. Background technique [0002] Radial sliding bearings are widely used in rotating machinery due to their outstanding advantages such as large load capacity, impact resistance, and good vibration resistance. At present, most radial sliding bearing test benches are mainly used to measure the static characteristics of sliding bearings, such as temperature, pressure, oil film thickness and other parameters representing static characteristics. A few radial sliding bearing test benches can measure the dynamic characteristics of sliding bearings. Due to the structure of some radial sliding bearing test benches, it is inconvenient to provide the working load of the bearing, and the test bearing cannot be replaced, which limits the type...

Problems solved by technology

Due to the structure of some radial sliding bearing test benches, it is inconvenient to provide the working load of the bearings, and the experimental bearings cannot be replaced, which limits the type and structure of the experimental bearings

Some radial sliding bearing test benches are limited by the lubrication conditions, and it is impossible to conduct experimental research on radial sliding bearings under the condition of changing the support stiffness.
