Motor and pump shaft connecting assembly with shaft locating jack ring

A coupling assembly for connecting a driven shaft to a selectively rotatable motor shaft for rotation therewith,

• the coupling assembly including,
• a split coupling sleeve being elongated in an axial direction from a forward end to a rearward end, the sleeve defining an axially located central bore, a first end of the central bore extending into the forward end of the coupling sleeve and being sized to at least partially receive therein an endmost portion of the motor shaft, the second other end of the central bore extending into the rearward end of the coupling sleeve and being sized to at least partially receive therein an endmost portion of the driven shaft,
• a lifting ring defining an open interior sized for circumferential placement about the driven shaft and being secured substantially against axially sliding movement relative thereto, the lifting ring including an aperture open in the axial direction, and
• a connector being insertable axially through said aperture into engagement with the rearward end of the coupling sleeve, whereby the engagement of the connector with the coupling sleeve moves the lifting ring and driven shaft in the axial direction relative to the coupling jacket and motor shaft.

A coupling assembly for connecting a driven pump shaft in a vertically axially aligned orientation with a selectively rotatable motor shaft of a motor for rotation therewith,

• the coupling assembly including,
• a coupling sleeve extending axially from a forward end proximate to said motor to a rearward end distal therefrom, the sleeve defining an axially located central bore, a first end of the central bore opening into the forward end of the coupling sleeve and being sized to at least partially receive therein an endmost portion of the motor shaft, the second other end of the central bore extending into the rearward end of the coupling sleeve and being sized to at least partially receive therein an endmost portion of the pump shaft, at least one internally threaded bore being spaced radially outwardly from said central bore and extending in the axial direction into the rearward end of the jacket,
• a lifting ring defining an open interior sized for circumferential placement about the pump shaft and being secured substantially against axially sliding movement relative thereto, the lifting ring including at least one aperture open in the axial direction, and located for positioning in substantial axial alignment with associated internally threaded bores upon coupling of the lifting ring to the pump shaft, and
• at least one threaded connector having a threaded end with a complementary thread configuration to said internally threaded bore, said connectors being insertable axially through a corresponding one of said apertures with said threaded end in threaded engagement with said associated threaded bore, whereby the turning of the threaded connectors moves the lifting ring and pump shaft in the axial direction relative to the coupling jacket and motor shaft.
