ROTARY INTO PROGRESSIVE MOVEMENT CONVERTER

摘要

FIELD: mechanics. ^ SUBSTANCE: invention relates to assemblies for converting rotary movement to progressive movement and may be used for various actuators including window lifts in cars. Converter consists of a grooved body in the form of closed shape, working element of progressive movement with drive coupling and rotary drive. Working element of progressive movement is a set of cylindrical or tapered rollers with circular grooves along generatix. Rollers are placed to each other in the grooves. Rotary drive in the shape of chain gear is installed so that in the points of teeth catching with rollers, they are located in holes formed by circular grooves between each two side-by-side rollers. ^ EFFECT: simplification of design; improvement of manufacturability, reliability and operation life time; wider field of application. ^ 2 dwg
