Abstract

The invention discloses a reliability test platform for a radial hydrostatic bearing. The reliability test platform for the radial hydrostatic bearing comprises a test platform support, a radial hydrostatic bearing assisting device, a regular Z-directional loading device, a negative Z-directional loading device, a regular Y-directional loading device, a negative Y-directional loading device and an automatic control device. According to the test platform, four sets of hydraulic loading devices are adopted to simulate dynamic and static pressure load of the radial hydrostatic bearing as well as loading within 360 degrees in the radial direction; the reliability test simulating the real working condition is performed for the tested radial hydrostatic bearing; in addition, the fault data are acquired in real time; therefore, practical foundation data are provided for later reliability evaluation, reliability modeling and reliability predicating, and as a result, the data acquiring time can be greatly shortened.

Description

technical field [0001] The invention belongs to the technical field of reliability testing of mechanical parts, in particular to a radial hydrostatic bearing reliability test bench which simulates actual dynamic and static pressure loads and can be loaded within a radial range of 360°. Background technique [0002] With the development of machines towards high efficiency and precision, hydrostatic bearings have received more and more attention because of their advantages such as low friction, large bearing capacity, and high precision. Hydrostatic bearings are divided into hydrostatic bearings and gas static pressure bearings according to different media. The hydrostatic bearing relies on the supplied pressure oil to form a pressure oil film in the bearing gap, so that the journal and the bearing are in a state of complete fluid friction. It usually consists of three parts: an oil supply system, a throttle and a bearing. The radial fluid Hydrostatic bearings have a wide ran...
