Claims15
A shaft extraction device comprising:
- a gripping element configured to grip a portion of a shaft having a longitudinal axis, and distribute a force applied to the gripping element over the portion;
- a clamping device, mounted on the gripping element, configured to releasably secure the gripping element to the shaft;
- and
- a force applying element, mounted on the clamping device, the force applying element being configured to allow an extraction force to be applied to the gripping element in a direction parallel to the axis of the shaft.
