Abstract
This study presents the numerical investigation of the behaviour of ball bearing 35-2310118E3C1 and its ability to work in helicopter transmission. A simplified mathematical model of transmission with ball bearings on rubber supports has been developed. The model was constructed taking into account the interaction between the cage and rings. The contact durability of bearing rings is calculated on the basis of "basic forces" and textolite cage rivet lifetime. Maximum allowable disbalances and vibratory velocities of transmission elements have been set depending on the cage rivets lifetime. Recommendations to increase the rivets lifetime are given.
