Analysis of the possibilities of organizing life tests of a conical bearing under external high-frequency force loading

Classical methods of bearing life tests have a number of disadvantages associated with the high cost and duration of tests, as well as the influence of many factors on the process of bearing failure. A promising direction is the development of modern methods of resource testing based on the technology of accelerated equivalent tests. This approach makes it possible to reduce the time of resource tests by using an external generator system that accelerates the process of bearing failure. In the work, the calculation of the loads acting on the body and the raceway is performed. The durability of the elements of a conical bearing was analyzed from the point of view of contact endurance, as a result of theoretical studies, it was concluded that the rings are the weakest elements. The equivalent number of loading cycles for accelerated tests has been calculated. An assessment of the possibility of using energy approaches and criteria for the destruction of metals for the organization of resource tests is also given.
