REVERSE DIFFERENTIAL Russian patent published in 2024 - IPC F16H48/00 F16H35/00 

FIELD: machine building.

SUBSTANCE: reverse differential consists of a driven shaft-disk with a cut groove of a semi-circular profile in the form of an Archimedean spiral, with which a satellite in the form of a ball bearing cage engages with retained balls with a radius similar to that of the groove. Satellite is made with possibility of linear movement along axis of drive shaft conjugated with it with splines of semi-circular profile with radius equal to radii of groove and balls, parallel to spiral plane. During spiral rotation, the rolling turns transmit torque through the satellite to the driven shaft-cone with a similar groove cut on the base, which is located on one axis, with its vertex to the vertex, with an identical shaft-cone. Parallel to the cone generatrix with the semi-circular profile grooves deposited on the side surfaces in the form of a spiral, there is an intermediate shaft with splines of a semi-circular profile with a radius equal to the radius of the grooves profiles, along which, positioned at any point along its axis, the conjugate satellite in the form of a sleeve with length equal to the cone generatrix moves linearly, ends of which are cages of ball bearings with retained balls with radius corresponding to radii of profiles of grooves and splines.

EFFECT: creation of differential, made with possibility of reversible, including multidirectional, stepless, with high accuracy to change angular speeds with high efficiency.
