FIELD: mechanical engineering; mechanical drives. SUBSTANCE: in different mechanism of known design version which has differential driving member where differential consists of central wheels and carrier with planet pinions located on carrier and feedback consisting of gear wheels closed on differential driven members. Power in this mechanism is taken off from feedback intermediate shaft and is transmitted in two parallel flows, ratio of parallel flows being negative. Drawback of such mechanism is harmful circulating power which leads to considerable decrease in efficiency. Novelty in proposed mechanism is that useful circulating power is created in closed differential mechanism by selecting ratios between members and displacing axes of epicycle and sun gear relative to each other. EFFECT: increased efficiency. 4 cl, 2 dwg |
