Contact Interactions of the Roller in a Planetary Roller Screw and Their Influence on the Load Capacity

Russian Engineering Research Aims and scope

Abstract

The load capacity of planetary roller screws may be increased, without increase in their size, by decreasing the profile angle of the screw threads. The profile angle affects the nonuniformity of the load distribution among the roller screws due to the tipping torque; that influence is investigated. A method is developed for balancing the tipping torque; a simplified diagram of the system is proposed. The nonuniformity is written as a function of the screw threads’ profile angle for the mechanism.
