FIELD: mechanical engineering. SUBSTANCE: proposed device includes two similar planetary mechanisms 1 and 2, each containing housing 3 with central gear wheel 4 internally meshing with planet pinion 5 whose pitch diameter d is equal to half of pitch diameter D1 of central gear wheel 4, shaft 6 of planet pinion 5 installed in carrier 7 engaging with housing 3, whose axis of rotation L coincides with longitudinal axis of symmetry of central gear wheel 4, crank 8 coupled with planet pinion 5. axes of rotation M and N of crank and planet pinion are parallel. Carrier 7 in each mechanism is formed by two parts 9 and 10 arranged opposite to end face planes α and β of central gear wheel 4 and engaging with housing 3 through main rolling bearing units 11 coaxial with central gear wheel. 4. Planet pinion 5 in each mechanism is rigidly connected with its shaft 6 installed in both parts 9 and 10 of carrier 7 through additional rolling bearing units 16. Crank 8 in each mechanism 1 and 2 is coupled with planet pinion 5 being secured on mounting member 17 of adjusting device to change center-to-center distance P between crank and shaft 6 of planet pinion 5. said adjusting device is secured by its support member 19 on one of ends of shaft 6 of planet pinion 5. both parts 9 and 10 of carrier 7 of each mechanism are rigidity intercoupled through one compensator 28. Housing 3 of mechanisms of proposed device are stationary intercoupled. Carriers 7 of mechanisms are intercoupled through gears 30 with equal pitch diameters D. Cranks 8 of mechanisms are mechanically intercoupled through rigid connecting link 31. EFFECT: improved reliability and increased service life of device, reduced internal unbalance, increased efficiency. 17 cl, 3 dwg
