<p>A downhole motor assembly including a housing, a power section with a stator and a rotor contained within the housing, a proximal drive assembly connected with a proximal rotor end, a distal drive assembly connected with a distal rotor end, a proximal thrust bearing arranged between the housing and the proximal drive assembly, a distal thrust bearing arranged between the housing and the distal drive assembly, and an axial load decoupling device in the distal drive assembly located longitudinally between the distal rotor end and the distal thrust bearing, for separating axial loads imposed on the proximal thrust bearing from axial loads imposed on the distal thrust bearing.</p> |
