An electrical submersible pump assembly has first and second modular component sections, each of the sections having an outer housing and an inner shaft member. A coupling sleeve having a bore is disposed between the modular component sections and receives the shaft member of each of the component sections. The bore of the coupling sleeve and the shaft members having mating radial load transmitting shoulders for transmitting torque. An axial load transmitting shoulder is affixed to the shaft member of the first modular component section and located in the bore of the coupling sleeve. A locking element is carried by the shaft member of the second modular section and engages the axial load transmitting shoulder to secure the shaft members to one another for transferring axial tension from one of the shaft members to the other.
L'invention concerne un ensemble pompe submersible électrique, qui comprend un premier segment et un second segment d'un élément modulaire, chaque segment présentant une gaine extérieure et un élément d'axe intérieur. Un manchon de raccordement présentant un alésage est disposé entre les segments de l'élément modulaire et reçoit l'élément d'axe intérieur de chaque segment. L'alésage du manchon de raccordement et les éléments d'axe intérieurs comportent des épaulements homologues de transfert de charge radiale pour transférer un couple. Un épaulement de transfert de charge axiale est fixé à l'élément d'axe du premier segment de l'élément modulaire et situé dans l'alésage du manchon de raccordement. L'élément d'axe du second segment modulaire reçoit un élément de verrouillage qui entre en prise avec l'épaulement de transfert de charge axiale pour arrimer solidement les éléments d'axe l'un à l'autre afin de transférer une tension axiale d'un élément d'axe à l'autre.
