Abstract

Pump apparatus, systems and methods of making and using same are disclosed. One inventive system includes a coupling member, a first shaft and a second shaft, the coupling member connecting the first shaft with the second shaft, the coupling member defining a first axial chamber accepting the first shaft, and a second axial chamber accepting the second shaft, the chambers separated by a coupling plate, the chambers including torsional motion transmitting elements and axial motion securing elements in the first and second axial chambers for axially securing the shafts in the coupling member. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims.

Dependent claims

A coupling member adapted to connect a first shaft with a second shaft, the coupling member comprising:

a first axial chamber adapted to accept a first end of the first shaft, and a second axial chamber adapted to accept a first end of the second shaft;
splines for transmitting rotational movement between the shafts, the axial chambers including the splines;
a coupling plate integral to the coupling member and positioned between the axial chambers wherein the coupling plate comprises a through hole adapted to accept a male portion of an axial motion securing member for securing the shafts from substantial axial movement during rotation of the shafts and coupling member;
and
at least one torque-limiting element responsive to a level of torque to rotatably decouple the first shaft and the second shaft.

2 more elements

A system comprising:

a coupling member for rotatably coupling a first shaft with a second shaft, the coupling member defining a first axial chamber accepting a first end of the first shaft, and a second axial chamber accepting a first end of the second shaft, wherein the coupling member comprises splines within each of the axial chambers for transmitting rotational movement between the shafts and a coupling plate integral to the coupling member and positioned between the axial chambers wherein the coupling plate comprises a through hole adapted to accept a male portion of an axial motion securing member for securing the shafts from substantial axial movement during rotation of the shafts and coupling member;
and
at least one torque-limiting element responsive to a level of torque to rotatably decouple the first shaft and the second shaft.
