ROTORS

The rotor is a gearbox that transmits rotation to the vertically suspended drill string from the horizontal shaft of the transmissions.

Main functions and purpose of the rotor:

• Transmits torque to the drill string.

Allows the drill pipe and bit to rotate while breaking rock.

• Supporting and holding the drill string.

The rotor is equipped with special wedges and gripping devices to hold the pipe during drilling and tripping operations.

• Provides drilling control.

Allows to adjust rotational speed and torque on the bit, ensuring efficient drilling of different rock types.

• Reduces the load on the top drive (if used).

In some drilling systems, the rotor works in conjunction with the top drive to distribute the load.

Where are rotors used?

• In rotary drilling - as the primary mechanism for rotating the drill string.
• In downhole operations - to hold and support the drill pipe.
• In combination drilling rigs - to work in conjunction with the top drive.

Rotor types:

• Conventional rotors - used in conventional drilling rigs with a drill table drive.
• Hydraulic rotors - have speed and torque control through the hydraulic system.
• Electromechanical rotors - run by an electric motor, providing precise rotational control.

Benefits of use:

• Provides stable and continuous rotation of the drill string.
• Allows pipe to be secured during drilling operations.
• Provides drilling control and reduces the possibility of accidents.
• Compatible with various types of drilling rigs.
