PARALLEL CIRCUIT SCREW GEAR Russian patent published in 2017 - IPC F16H25/22 F16H25/02 

FIELD: machine building.

SUBSTANCE: parallel circuit screw gear comprises a screw (1), nuts (2), rollers (4) in the separators (5), cup (6), leads (7) and plug (11). Nuts with rollers are combined by the Assura group with the use of leads. Rollers (12) exclude nuts (2) relative rotation. Rollers (4) and nuts (2) have an equation of a screw pitch and its tilt angles, the noted angles do not coincide with the tilt angle of screw thread (1). A total capacity of all nuts affects the links of the Assura group. Assur group is statically determinate kinematic chain and the distribution of forces in the kinematic pairs and links is identical.

EFFECT: increasing load capacity.
