FIELD: mechanical engineering. SUBSTANCE: planetary roller helical gearing includes screw, rollers and nut. Backlashes between them are taken up due to deformation of nut in radial direction. Nut is made in form of solid thin-walled shell of revolution with projecting surfaces at ends for engagement with nut deforming mechanism. These surfaces shall project to ends of shell by no less than 1 mm to exclude contact of ends with parts of above-mentioned mechanism and to ensure free deformation of shell. EFFECT: enhanced reliability. 5 dwg
