FIELD: mechanical engineering. ^ SUBSTANCE: invention can be used in systems with piston, slider and other units. Proposed mechanism has housing, guides 2, slider 3, output shaft 4 with circumferential section 5 of gear rim alternately engaging with two sections 6, 7 of rim (racks) arranged from side of slider 3 with teeth orientated in opposite direction. End working teeth of edges of rim sections 5-7 are made with body truncation surface having at least one bend and orientated with tilting at acute angle by one extremity to surface of point and by other extremity, square to one of end faces. Surface of truncation of tooth body together with cut of top surface on opposite sections 5 and 6 or 5 and 7 of rim is orientated so that corresponding pairs of working teeth are aligned with ridges at insignificant clearance at opposite relative displacement. ^ EFFECT: reduced level of vibrations, eliminated possibility of wedging. ^ 6 cl, 21 dwg |
