ABSTRACT:
Herein presented and claimed is a removable sleeve-to-shaft interlock for a dynamoelectric machine. The invention comprises: a shaft having a groove about its outer circumferential surface; a sleeve having a central bore for receiving said shaft therethrough, said sleeve having an eccentric groove about its inner circumferential surface; at least one detent, said detent being an arcuate spring having an associated radius smaller than the radius of the shaft and an associated height greater than the depth of the shaft groove, said detent depressible during assembly and disassembly; and means for circumferentially positioning said detent in the shaft groove, for example at least one spacer having at least one protrusion which mates with a similarly shaped channel in the non-eccentric groove. After assembly the detent straddles the interface between the shaft and the sleeve, being within both of the grooves simultaneously, thereby preventing axial movement of the sleeve relative to the shaft.
