摘要： An electrical submersible pump has a pump assembly joined to a seal section. The pump assembly shaft, which may experience upthrust axial forces, may joined to the seal section shaft by a detachable coupling. The detachable coupling may have splines on its inner diameter that engage splines on the outer diameters of the pump assembly shaft and the seal section shaft. The detachable coupling can be bolted to one of the shafts. Locking members, such as plates, can be inserted through slots on the coupling to engage a recess on one of the shafts. A retaining device, such as a sleeve, can be used to hold the locking members in place.
