Abstract

A downhole screw motor comprises a casing (1) containing inside it working organs consisting of two elements: an external one which is made as a bushing (2) with inner spiral teeth (2'), and an internal one which is made as a shaft (3) provided with external spiral teeth (3'). The teeth (2') and (3') of the bushing (2) and the shaft (3) are in the permanent meshing. The bushing (2) is connected to an output shaft (4) mounted in the casing (1) in axial bearings (5). The spiral shaft (3) is mounted in the casing (1) with the possibility of its radial displacements and with the prevention of its rotation about its own axis. Radial supports (10) are provided between the casing (1) and the bushing (2) within the area of location of its spiral teeth (2').

When operating fluids and fluids through the operating system under the influence of the onset pressure drop, the operating units begin to be displaced by other items of clothing. Β in the most modern engine layout, the right bushing is not movable, and the inner shaft makes - 2 - planetary motion - it describes the need for the outer sleeve and the single inner shaft rotates around its own body. This rotation is carried out to the output shaft of the engine. There are also other types of movement of the workers of the corgan, for example, when the external element rotates, and the internal makes a vibrating (erratic) movement. By changing the number of teeth and the length of the pitch of the screw teeth, it is possible to obtain any necessary motor characteristics. The source of energy for the operation of the engine is usually a liquid, but the engine can run on aerated liquid and compressed air.

At the same time, the maximum reduction in the level of vibration is achieved and the most favorable conditions of operation for the engine components are provided. When the jna of the radial hub is less than the jna of the section of the hub with helical teeth, full stabilization of the orientation of the rotating hub is not ensured and the rotation of the rotating hub is not always necessary.
