“…In summary, the failure analysis of the cage rivets is mostly carried out from the failure fracture and metallographic structure. Murashkina et al [19] used the results of the multi-body dynamic simulation of a ball bearing in the cage strength analysis. The stress and deformation of the cage and rivets were presented.…”

This study focuses on the rivet early fatigue characteristics in a deep-groove ball bearing cage for a transmission system in a turboprop engine. Nonlinear dynamic differential equations for the deep-groove ball bearing with a two-piece cage were developed. The rivet stress was used to identify the early failure mechanism of the rivets. This investigation revealed that by delivering an optimal preload of the rivet causes the two halves of the cage have less misalignment and a lower rivet stress. The fit relationship between the rivet and the rivet bore has a significant influence on the rivet stress. Excessive clearance increases the stress on the head of the rivet, while excessive interference increases the stress on the middle of the rivet. For the 1.5 mm diameter rivet analyzed in this study, the appropriate fit relationship is −0.02 mm–0 mm. A reasonable matching value of the load and the speed and the cage clearance ratio are beneficial to reducing the rivet stress. The impact load acting on the bearing and a ring misalignment can increase the rivet stress.

Occurring during operation inhomogeneity of the contact pressure distribution between the rollers and the bearing rings due to skew affects the durability and dynamics of the bearing parts. The article describes a modified method of normal contact pressure determination according to the theory, based on the Bousinessque equation. The efficiency of the method is estimated and results of numerical simulation of normal contact pressure distribution in the contact of the roller with the raceway of the inner ring of the cylindrical roller bearing for different roller profiles, loads, and skew angles are presented. It is shown that the logarithmic profile creates the lowest pressure concentration at the ends of the roller.
