PULSE ROTATOR OF MACHINE WORKING ATTACHMENT Russian patent published in 2014 - IPC E21B6/06 E21C31/04 F16H25/16 

FIELD: mechanical engineering.

SUBSTANCE: pulse rotator of a machine working attachment comprises a rotary actuator, a drive and driven shafts, a cam, a pusher. The shafts of the driven and driving gears are made parallel. The cam is made as a circular tooth profile of the drive gear, and tooth cavities in the form of a recess performing the role of the pusher are made on the driven gear. Tooth thickness is selected based on the relationship: S=30·d·ω/p, where S - tooth thickness of the driven gear, d - diameter of the driven gear, ω - angular velocity of rotation of the driven gear, p - frequency of oscillation of the given work process. The maximum value of the inclination angle of the recess is chosen based on the relationship: α=arctg f, where α - angle of inclination of the recess, f - friction coefficient of the cam and pusher kinematic pair.

EFFECT: improved operational reliability, efficiency and service life of the pulse rotator operation.
