Horizontal assembly of stator core using keybar extensions
The present invention provides an apparatus for the horizontal stacking of laminations 10 and donuts to form a stator core. A stator generator frame 2 has multiple keybars 6 that run the axial length of the frame. The laminations 10 have grooves 12 there-in that engage the keybars to provide a secure fit of the laminations to the generator frame. By extending two or more of the keybars 6 , these extensions 7 may be used as rails on which the laminations may be horizontally inserted into the stator frame.
1. An apparatus for horizontally assembling a stator core comprising:
a plurality of keybar extensions comprising at least one of a screw-in prosthetic and a tongue and groove prosthetic; and
a plurality of keybars, wherein said plurality of keybars are part of a stator frame, wherein said stator frame has two ends and wherein said plurality of keybar extensions are attached at a first end of said stator frame to at least two of said plurality of keybars using the screw-in prosthetic or the tongue and groove prosthetic so that the keybar extensions extend outside of the stator frame;
wherein laminations placed on said apparatus engage said keybar extensions on the outer diameter of the laminations to be slid onto the keybars, and wherein the keybar extensions are removed from the keybars once the stator core is assembled.
2. The apparatus of claim 1 , wherein the laminations comprise a lamination donut.
