Abstract
The invention relates to an actuating unit for downhole helical pumps, used for driving sucking rods in the oil production process. The actuating unit for downhole helical oil pumps comprises an electric motor (3) having a variator (A) with wide V-shaped belt, and a reductor (B) whose output shaft (7) is located between the branches of a belt (6) or among the branches of a V-shaped belt assembly (23) and coupled to the sucking rod (8) by means of a clamping system (c) resting against a plate (43) by means of another disc (48) forming a spherical bearing, a one-way coupling (9) being attached to the bottom end of the output shaft (7). The reductor (B) is provided with an internal bore (b) wherethrough the sucking rod passes, and the output shaft rests supplementarily on an axial bearing (41), the internal sealing of the lower axial bearing (40) being achieved by means of a cup (42).
