“…The duration of the sawtooth section depends on the state of the friction surfaces in the contact pair, on possible misalignment of the ring and shaft, and does not depend on the amount of interference. With uniform movement of the ring along the shaft, a smooth decrease in the value of the depressurization force is observed on the graph, due to a decrease in the contact area in the "ring-shaft" contact pair, which continues until the ring is completely removed from the shaft and the force reaches zero [5]. Figure 2 shows graphs of the depressing force versus time for samples with tensions of 55, 77 and 90 µm.…”

The destruction of the bearing ring of the axle box unit inevitably leads to the uncoupling of the car, which causes temporary and material losses. The problem of determining the bearing ring tension without removal is relevant; its solution will improve efficiency and reduce the inspection time. Experimental studies were carried out to determine the forces inside the contact pair, as well as their relationship with the amount of interference. It has been established that with small impacts on the ring, surface deformations in the area of impact are uneven and form a gradient in which large deformations are observed at the edge of the ring, smaller ones in the middle. It has been proven that the transition boundary of the magnitude of deformations depends on the magnitude of the interference in the contact pair. A method for determining the tension by strain gauging is proposed.
