Description

Technical Field

[0001] The invention belongs to the technical field of bearing load detection and relates to a bearing load simulation detection device. Background Art

[0002] Bearings are a widely used mechanical part, and their service life directly affects the life of the machinery that uses them. Therefore, understanding the load conditions of bearings during the actual working process of the machinery has a very positive effect on accurately estimating the service life of bearings or rationalizing the design of bearing structures. Bearing load means the load that the bearing is subjected to when in use, including lateral loads and longitudinal loads. When in use, the bearing supports the rotating shaft, and the shaft may be subjected to radial or axial loads. These loads will act on the bearing. For example, the helical gear shaft on the reducer will have axial loads generated during the transmission process, and the bearing will be subjected to axial loads at this time.

[0003] Most existing bearing load testing equipment relies on adding weights to simulate the load borne by the bearing, but this method has major defects. For example, it is not easy to place the test weight. At the same time, most existing bearing load testing equipment can only be used for radial or axial testing of bearings. When testing the same bearing, it is often necessary to change the position of the bearing, which will affect the test results of the bearing. Therefore, we propose a bearing load simulation detection device. Summary of the invention
