摘要： A press-fit bearing locking system, apparatus and method is described. A press-fit bearing locking system includes a diffuser having a diffuser groove on an inner diameter (ID), a bushing comprising an outer diameter (OD) press-fit into the grooved ID of the diffuser, the OD of the bushing having a bushing groove tracing a path of the diffuser groove, and a high thermal expansion material (HTEM) key seated within the bushing groove. A press-fit bearing locking method includes seating a HTEM key inside a groove on an OD of a bushing, press-fitting the bushing with HTEM key into a diffuser such that the bushing groove is opposite a groove on an ID of the diffuser, operating an electric submersible pump assembly including the diffuser during a temperature rise, and allowing the HTEM key to expand into the diffuser groove during the temperature rise to lock the bushing against the diffuser.

摘要： A torque transfer system for centrifugal pumps. A torque transfer system for a centrifugal pump includes a bearing sleeve above an impeller, the bearing sleeve and a hub of the impeller surrounding a rotatable shaft and coupled to the rotatable shaft by a key, the bearing sleeve having a stepped bottom edge, a top edge of the hub stepped inversely to the bottom edge of the bearing sleeve such that the top edge and the bottom edge interlock with a clearance between longitudinally extending portions of the interlocked edges, wherein upon reduction of torque transference between the key and the sleeve, the clearance closes such that the longitudinally extending portion of the stepped top edge contacts the longitudinally extending portion of the stepped bottom edge thereby maintaining rotation of the sleeve with the rotatable shaft. A centrifugal pump includes modules with a series of stepped, interlocked impellers.
