Embodiment Construction
[0030] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0031] For the convenience of description, spatially relative terms may be used here, such as "on ...", "over ...", "on the surface of ...", "above", etc., to describe the The spatial positional relationship between one device or feature shown and other devices or features. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, devices described as "above" or "above" other devices or configurations would then be oriented "beneath" or "above" the other devices or conf...

The invention provides an integrated bearing test bench, which comprises a sensing assembly, a loading system, a temperature adjusting device, a loading device, a tested bearing pack, an accompanyingtest bearing pack, a base, a cylinder and a rotatable central rotating shaft penetrating through the cylinder, and is characterized in that the central rotating shaft is perpendicular to the horizontal plane; the accompanying test bearing pack, the loading device and the tested bearing pack are located in the cylinder and sequentially installed on the central rotating shaft from bottom to top, theloading system applies pressure to the tested bearing pack through the loading device, and information sensed by the sensing assembly comprises the pressure of the tested bearing pack and the environment temperature where the tested bearing pack is located. The temperature adjusting device adjusts the temperature of the environment where the tested bearing set is located. According to the invention, high-temperature test and high-thrust loading are combined, the test temperature and the loading thrust are adjustable, the axial thrust cannot be loaded on the test bed, force sealing is carriedout through the central rotating shaft, and the test bed is compact in overall structure, relatively low in cost, good in stability and reliable in work.
Description
technical field [0001] The invention relates to the technical field of bearings, in particular to an integrated bearing test bench. Background technique [0002] In engineering applications, the bearings of some equipment will withstand the harsh environment of ultra-high temperature and large thrust during normal operation, such as deep well pump equipment for crude oil exploration at a depth of 2,000 meters underground. When bearing an oil temperature of 250°C, it will also withstand a large thrust of tens of tons. In the development stage of this type of bearing, it is an essential step to test the bearing in the relevant harsh environment to verify whether it meets the requirements of use. However, in view of the current loading test benches, there are few test benches that can satisfy the high temperature test of bearings and can carry out high thrust loading at the same time. Contents of the invention [0003] In view of the above-mentioned problems existing in the...
