PULSE ROTATOR OF MACHINE WORK MEMBER Russian patent published in 2011 - IPC E21B3/02 E21B6/06 

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. External arms and working sections of arms have different length and different angles of incline in each cam-pusher. Values of length and angle facilitate successive increment of torque pulse of each cam-shaft per one cycle at an idle run of the rest of the cams-pushers.

EFFECT: increased reliability and durability of cam-pusher, protection from resonance negative effect, improved process.
