Stators shrink-fit into the housings:
Machining fixture turned into a guide fixture for the shrink-fit operation
Band heater wrapped around the housing to keep it hot while installing the stator:
Borrowed the pneumatic powered hydraulic press at work to make sure the stators didn't get stuck half way down:
3D printed 2-axis flexture kept the stators parallel to the housing but allowed them to center to the housing bore:
Is the guide rod with the stator somehow on it beeing pushed inside the housing? If so how does the rod grip the stator? Surely the 3d printed part is not transferring the force of the 40 ton hydraulic press to the stator? Very interesting as always, happy whenever there is a new post :)
ReplyDeleteThe guide rod was fixed to the aluminum fixture under the stator in the press. The printed flexure is a light press fit into the stator and a slip fit on the guide rod. So the stator slides up and down the guide rod, and is held perpendicular to the guide rod (and the housing) by the flexure. The press pushed directly on the stator lamination stack.
DeleteMakes perfect sense, thank you :)
