Abstract

A vertical in-line split couple pump includes a motor shaft having a motor shaft collar; a pump shaft having a pump shaft collar with a pump shaft angled collar surface oblique to an axis of the motor and pump shafts; and a coupler having coupler halves that attach together, that have a couple groove to receive the motor shaft collar, and have a couple angled groove to receive the pump shaft collar. The couple angled groove has a couple angled groove surface oblique to the axis. The coupler halves respond to a force that moves them together to couple the pump and motor shaft together, moves the pump shaft angled collar surface in relation to the couple angled groove surface, causing the pump shaft to move upwardly towards the motor shaft along the axis, to provide a way to jack-up and recouple the pump shaft and any impeller attached thereto by one mechanic.

First claim

What we claim is:

1 . Apparatus comprising:
a motor shaft configured with a motor shaft collar; a pump shaft configured with a pump shaft collar having a pump shaft angled collar surface that is oblique to an axis of the motor shaft and the pump shaft; a coupler having two coupler halves configured to attach together to couple the pump shaft and motor shaft, configured with a couple groove to receive the motor shaft collar, and configured with a couple angled groove to receive the pump shaft collar, the couple angled groove having a couple angled groove surface that is oblique to the axis of the motor shaft and the pump shaft, the coupler halves configured to respond to a force that moves the coupler halves together to couple the pump shaft and motor shaft together and also moves the pump shaft angled collar surface in relation to the couple angled groove surface, causing the pump shaft to lift or move upwardly towards the motor shaft along the axis, so as to provide a way to jack-up and recouple the pump shaft and any impeller attached thereto by one mechanic.

2 . Apparatus according to claim 1 , wherein the pump shaft collar comprises a tapered washer that is attached to an end of the pump shaft.

3 . Apparatus according to claim 1 , wherein the pump shaft collar and the pump shaft are formed as an integral unit, including being molded together as one piece.

4 . Apparatus according to claim 1 , wherein the motor shaft collar comprises a tapered washer that is attached to an end of the motor shaft.

5 . Apparatus according to claim 1 , wherein the motor shaft collar and the motor shaft are formed as an integral unit, including being molded together as one piece.

6 . Apparatus according to claim 1 , wherein
the motor shaft collar is configured or formed with a tapered washer that is attached to an end of the motor shaft, the tapered washer including a motor shaft angled collar surface that is oblique to the axis; and the couple groove is angled and has a motor shaft couple groove surface that is oblique to the axis, so that when the coupler halves respond to the force, the motor shaft angled collar surface moves in relation to the motor shaft couple groove surface, causing the pump shaft to lift or move upwardly towards the motor shaft along the axis.

7 . Apparatus according to claim 1 , wherein the apparatus comprises, or forms part of, a vertical in-line split couple pump.

8 . Apparatus comprising:
a motor shaft having a motor shaft collar configured or formed with a motor shaft angled collar surface that is oblique to an axis of the motor and pump shafts; a pump shaft having a pump shaft collar; and a coupler having two coupler halves configured to attach together, configured with a couple angled groove to receive the motor shaft collar, the couple angled groove having a couple angled groove surface that is oblique to the axis of the motor and pump shafts, and configured with a couple groove to receive the pump shaft collar, the coupler halves configured to respond to a force that moves the coupler halves together to couple the pump shaft and motor shaft together and also moves the motor shaft angled collar surface in relation to the couple angled groove surface, causing the pump shaft to move upwardly towards the motor shaft along the axis, so as to provide a way to jack-up and recouple the pump shaft and any impeller attached thereto by one mechanic.

9 . Apparatus according to claim 8 , wherein the motor shaft collar comprises a tapered washer that is attached to an end of the motor shaft.

10 . Apparatus according to claim 8 , wherein the motor shaft collar and the motor shaft are formed as an integral unit, including being molded together as one piece.

11 . Apparatus according to claim 8 , wherein the pump shaft collar comprises a tapered washer that is attached to the pump shaft.

12 . Apparatus according to claim 8 , wherein the pump shaft collar and the pump shaft are formed as an integral unit, including being molded together.

13 . Apparatus according to claim 8 , wherein
the pump shaft collar is configured or formed with a tapered washer that is attached to the end of the pump shaft, the tapered washer including a pump shaft angled collar surface that is oblique to the axis; and the couple groove is angled and has a pump shaft couple groove surface that is oblique to the axis, so that when the coupler halves respond to the force, the pump shaft angled collar surface moves in relation to the couple angled groove surface, causing the pump shaft to move upwardly towards the motor shaft along the axis.

14 . Apparatus according to claim 8 , wherein the apparatus comprises, or forms part of, a vertical in-line split couple pump.
