Abstract

The strength of separators of roller bearings taking into account their operation, performance and design features is proposed to estimate using the load factor of separator, comprising the dynamic factor of external load, dynamic factor of load on separator by rollers, load factor of separator at misalignment, stress concentration factor. Dynamic factor of external load of bearing assesses intensity of the load, acting on the bearing assembly of the machine, and is defined by the industry reliability service. Dynamic factor of load on separator by rollers is determined by calculating the shock load of the separator with rollers and according to the mechanism of motion transmission from the roller to the separator. The load factor of  the standard separator at misalignment to the locator ring of the bearing is determined by the model of contact between two non-centrally loaded cylinders. Determining the stress concentration factor is performed by calculating the separator design using the finite element method. The conducted studies of the load factor of separators of roller bearings will be used to develop an analytical method for calculating the separator strength.
