ABSTRACT:
A device for releasing tension in a pump shaft is shown and described. An annular elastomeric member is positioned on the circumference of the pump shaft, the elastomeric member having circumferentially spaced holes provided in a surface distal to the shaft. The elastomeric member is confined in an axial direction, and a volume control member is positioned in each of the holes, such that the elastomeric member is also confined in a radial direction. During operation of the pump, the torque on the pump shaft induces a tensile load on the shaft which in turn causes a compression load on the components mounted on the shaft, the compression load being borne by the elastomeric member. After operation of the pump, the volume control members are retracted from the holes, such that the elastomeric member is allowed to compress, thereby unloading the shaft and connection to the pump impeller. The impeller may then be easily unscrewed and removed from the pump shaft.
