FIELD: machine building.

SUBSTANCE: pulse rotator consists of two parts of shaft of work member, of cam-pusher made in form of two-arm lever and interacting with parts of shaft, and of stationary cams on internal surface of reducer case. A driven part of the shaft is equipped with a flexible element facilitating bond between the parts of the work member shaft.
