HARMONIC RACK-AND-GEAR DRIVE WITH INTERMEDIATE LINKS IN FORM OF WEDGES Russian patent published in 2012 - IPC F16H19/04 

FIELD: machine building.

SUBSTANCE: harmonic rack-and-gear drive with intermediate links in the form of wedges includes housing (1), rack (2), wedge movement device (4) orthogonal to the rack, which consists of shaft (6) and flat cams (8) installed on it along its axis through screw line. Diaphragm (11) is installed between housing and wedges. Rack has the possibility of being moved in guides of housing parallel to shaft axis. Brolling bearings (9) are installed in wedges with possibility of direct interaction of their inner rings with working surfaces of flat cams (8). Rollers (10) are installed in the rack with constant pitch and with possibility of being rotated about their axes. Rollers interact with wedges subsequently displaced in phase relative to each other only in straight-line sections of their back-and-forth movements.

EFFECT: uniform tractive force on rack, and rigid drive.
