Abstract

The arrangement is intended for coupling the rotor of a worm pump to its drive shaft (3) via a coupling shaft (2) and a homo-kinetic coupling (6). It comprises a coupling head (7) releasably secured to the end (12) of one shaft (3). The head is cup-shaped and sealed by a compressible seal ring (23) relative to the end (12) to which it is fixed by an axial screw (8) through the bottom (10) of the cup. It is located against rotation by at least one cylindrical pin (13) eccentrically positioned in the bottom (10) or in the end (12) to engage a complementary bore (14) in end (12) or bottom (10).
