Planetary roller screw transmissions are the most promising converters of rotational to translational motion. PRVP studies are relevant, which determine the relationship between the manufacturing accuracy of the screw, rollers and nuts of the PRVP with its operational parameters. These relationships are planned to be determined by statistical and probabilistic methods using simulation modeling methods. Among the operational parameters, it is planned to investigate the kinematic error, rigidity, static load capacity and dynamic load capacity of the PRVP. The object of the study is a PRVP with a long screw and axial backlash.
