Title (EN) SOFT COATING FOR SPLINED CONNECTIONS BETWEEN MOTOR SHAFTS OF SUBMERSIBLE PUMP ASSEMBLY
(FR) REVÊTEMENT MOU POUR LIAISONS CANNELÉES ENTRE DES ARBRES MOTEURS D'ENSEMBLE POMPE SUBMERSIBLE
Abstract:
(EN) An electrical submersible pump assembly (21) has modules, including a pump (23), a seal section (29) and a motor (31). A rotatable first drive shaft (33) in a first one of the modules has a splined end (37) that mates with a splined end (45) of a rotatable second drive shaft (43) in a second one of the modules. An external set of splines (39, 47) is on mating ends of the first drive shaft and the second drive shaft. A coupling (49) has an internal set of splines that mesh with the external set to rotationally couple the first and second drive shafts to each other. A polymer coating (57) is selectively bonded on one of the sets and in sliding engagement with the other set. The coating is a solid polymer material having a lower coefficient of friction than steel alloys of the internal set and the external set.
(FR) L'invention concerne un ensemble pompe submersible électrique (21), lequel ensemble a des modules, comprenant une pompe (23), une section d'étanchéité (29), et un moteur (31). Un premier arbre d'entraînement rotatif (33) dans un premier module parmi lesdits modules a une extrémité cannelée (37) qui s'accouple avec une extrémité cannelée (44) d'un second arbre d'entraînement rotatif (43) dans un second module parmi lesdits modules. Un ensemble externe de cannelures (39, 47) se trouve sur des extrémités d'accouplement du premier arbre d'entraînement et du second arbre d'entraînement. Un accouplement (49) a un ensemble interne de cannelures qui s'engrènent avec l'ensemble externe pour coupler en rotation les premier et second arbres d'entraînement l'un à l'autre. Un revêtement polymère (57) est lié de manière sélective à l'un des ensembles et coulisse au contact de l'autre ensemble. Le revêtement est un matériau polymère solide ayant un coefficient de frottement inférieur à celui des alliages d'acier de l'ensemble interne et de l'ensemble externe.
