Title (EN) DOWNHOLE SCREW MOTOR
(FR) MOTEUR A VIS POUR FOND DE PUITS
Abstract: front page image
(EN)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').
(FR)Un moteur à vis pour fond de puits comprend une enveloppe (1) contenant des organes de travail consistant en deux éléments: un élément externe qui est constitué comme un manchon (2) avec des dents spiralées internes (2') et un élément interne se présentant comme un arbre (3) pourvu de dents spiralées externes (3'). Les dents (2') et (3') du manchon (2) et de l'arbre (3) sont en prise en permanence. Le manchon (2) est connecté à un arbre de sortie (4) monté dans l'enveloppe (1) dans des paliers axés (5). L'arbre hélicoïdal (3) est monté dans l'enveloppe (1) avec la possibilité d'effectuer des déplacements radiaux mais ne pouvant tourner autour de son propre axe. Des supports radiaux (10) sont prévus entre l'enveloppe (1) et le manchon (2) dans la zone de ses dents spiralées (2').
