FIELD: mechanical engineering; machine tools and mechanisms executing reverse rotary motion. SUBSTANCE: proposed hydraulic drive is designed for synchronization of output links of actuating members of machines, mechanisms and machine tools converted to hydraulic operation. Outlet of flow governor 12 of master hydraulic motor 1 is connected with second cylinder branch 10 of three-position hydraulic distributor 9 and, through pressure slide valve 14, with outlet of flow governor 21 of synchronized hydraulic motor 4 and, through additional two-position hydraulic distributor 15, with outlet 3 of master hydraulic motor 1. First cylinder branch 11 of three-position hydraulic distributor 9 is connected with drain through additional two-position hydraulic distributor 15. EFFECT: reduced overall dimensions and weight, improved reliability. 1 dwg
