Abstract
A shaft coupling for connecting a first shaft to a second shaft includes a first hub that has a shaft sleeve that fits over a portion of the first shaft. The first hub also includes a connection flange connected to the shaft sleeve. The shaft coupling further includes a compression fitting that fits over the shaft sleeve to apply a compressive force to the shaft sleeve and first shaft. The shaft coupling further includes a second hub that is connected to the second shaft and to the first hub.
Claims20
A horizontal pumping system comprising:
- a suction chamber connected, wherein the suction chamber includes a stub shaft;
- a thrust chamber, wherein the thrust chamber includes a thrust chamber shaft that delivers torque to the stub shaft;
- and
- a shaft coupling connecting the thrust chamber shaft to the stub shaft, wherein the shaft coupling comprises:
- a thrust shaft hub, wherein the thrust shaft hub is connected to the stub shaft and to the thrust chamber shaft;
- and
- a compression fitting, wherein the compression fitting is connected to the thrust shaft hub.
A shaft coupling for connecting a thrust chamber shaft to a stub shaft, wherein the shaft coupling comprises:
- a thrust shaft hub, wherein the thrust shaft hub is connected to the stub shaft and to the thrust chamber shaft;
- and
- a compression fitting, wherein the compression fitting is connected to the thrust shaft hub.
A shaft coupling for connecting a first shaft to a second shaft, wherein the shaft coupling comprises:
- a first hub, wherein the first hub comprises:
- a shaft sleeve, wherein the shaft sleeve fits over a portion of the first shaft;
- and
- a connection flange connected to the shaft sleeve;
- a compression fitting, wherein the compression fitting fits over the shaft sleeve to apply a compressive force to the shaft sleeve and first shaft;
- and
- a second hub, wherein the second hub is connected to the second shaft and to the first hub.
The shaft coupling of claim 19, wherein the first hub is removably connected to the first shaft.
