VARIABLE-SPEED DRIVE Russian patent published in 1998 - IPC

FIELD: mechanical engineering; automatic control of revolutions and torque of driven member. SUBSTANCE: drive has pulse generator of other construction as compared with standard pulse generators. Pulse generator is made in form of rotor drum with eccentric bore mounted in housing; holder and pusher are mounted in this bore; pusher has radial holes and pins received by these holes for engagement with outer surface of holder and inner surface of drum and shut-off device fitted on rotor drum.
