MOBILITY OF PROGRESSIVE CAVITY PUMPS
(PCP) GEAR COUPLINGS
The writing represents a study on the angular mobility of the toothed
surfaces used for the progressive cavity pumps (PCP), in the transmission from
the drive shaft to the pump rotor: the teeth bulging and the play between the
flanks, the contact conditions of the teeth based on the blocking contour of an
inner gear with zero tooth number difference.
Keywords: gear couplings, progressive cavity pumps (PCP)
