FIELD: oil producing industry.
SUBSTANCE: invention is designed to control reciprocation of sucker-rod pump. Inlet and outlet mechanisms are made in form of coaxial shafts with friction wheels fitted on ends. Transmission is made in form of friction disk installed in movable holder capable of displacing along axis of inlet and outlet mechanisms. Friction wheels are spring-loaded by rollers are arranged at reverse side of friction disks for pressing to friction disk. Gear ratio changer is made in form of screw mechanism with possibility of rectangular displacement of friction disk movable holder.
EFFECT: possibility of control of speed of oil well sucker-rod pump within wide range both at manual and automatic mode of operation.
