Abstract
A shaft coupling is useful for connecting a distal end of a first shaft with a proximal end of a second shaft. The shaft coupling includes a body, a first receiving chamber within the body and a second receiving chamber within the body. The first receiving chamber receives the distal portion of the first shaft and the second receiving chamber receives the proximal portion of the second shaft. A pin maintains the axial positioning between the body and the distal portion of the first shaft. An axially adjustable connection is used between the second receiving chamber and the proximal portion of the second shaft.
Claims20
A shaft coupling for connecting a distal end of a first shaft with a proximal end of a second shaft, wherein the second shaft includes an axially-directed center bore extending from the proximal end, the coupling comprising:
- a body,
- a first receiving chamber within the body, wherein the first receiving chamber receives the distal portion of the first shaft;
- a second receiving chamber within the body, wherein the second receiving chamber receives the proximal portion of the second shaft;
- a lock pin;
- wherein the lock pin extends through the body and through distal end of the first shaft;
- and
- an axial shaft bolt captured within the body of the coupling, wherein the axial shaft bolt is threadingly engaged to the center bore of the second shaft.
An electric submersible pumping system comprising:
- a motor, wherein the motor includes a motor shaft that transmits torque from the motor;
- a pump, wherein the pump includes a pump shaft and wherein the pump is configured to discharge fluid toward the motor;
- a seal section connected between the pump and the motor, wherein the seal section includes a seal section shaft;
- and
- a shaft coupling connected between the seal section shaft and the pump shaft, wherein the coupling comprises:
- a body;
- a first receiving chamber within the body, wherein the first receiving chamber receives the seal section shaft;
- a second receiving chamber within the body, wherein the second receiving chamber receives the pump shaft;
- a lock pin;
- wherein the lock pin extends through the body and through the seal section shaft;
- and
- an axial shaft bolt captured within the body of the coupling, wherein the axial shaft bolt is threadingly engaged to the pump shaft.
A shaft coupling for connecting a distal end of a first shaft with a proximal end of a second shaft, the coupling comprising:
- a body;
- a first receiving chamber within the body, wherein the first receiving chamber receives the distal portion of the first shaft;
- a pinned connection between the body and the distal portion of the first shaft;
- a second receiving chamber within the body, wherein the second receiving chamber receives the proximal portion of the second shaft;
- and
- an axially adjustable connection between the second receiving chamber and the proximal portion of the second shaft.
