FIELD: oil-chemical industry.
SUBSTANCE: electric drive comprises external drive and gearing with intermediate rolling bodies. The gearing has input shaft and cam which is mounted on the input shaft and made of three same disks. The disks are secured to the bases so that their centers are arranged symmetrically around the axis of the input shaft. The electric drive comprises central wheel with inner teeth and separator. The grooves in the separator receive three rows of intermediate rolling bodies that kinematically connected with the cam and central wheel. The input shaft of the gearing with intermediate rolling bodies is secured to the external drive. The input shaft is mounted in two rolling bearings. One of the rolling bearings is made of intermediate rolling bodies.
EFFECT: enhanced reliability and simplified structure.
