Abstract
PURPOSE:To reduce the number of component parts to be used in a rotary electric machine by forming a rectangular projection on the inner peripheral surface of a rotor rim, inserting the projection into the coupling slot on the outer peripheral surface of a spider, press-fitting tapered cotters into the slot and coupling the both, thereby eliminating the stress increase by the slot. CONSTITUTION:An axially rectangular projection 1D is integrally formed at the position corresponding to the coupling surface of a rotor rim 1 with a spider 2 on the inner peripheral surface of the rim 1. A coupling slot 2A is formed on the outer periphery of the spider 2, and the projection 1D of the rim 1 is inserted into the slot. The slot 2A is axially tapered to form a tapered air gap at the side 2A is axially tapered to form a tapered air gap at the side faces of the projection 1D and slot 2A. Tapered cotters 3A, 3B are press-fitted into the tapered air gap formed between both side faces of the projection 1D and the side face of the slot 2A in the state that the projection 1D is inserted into the slot 2A, thereby clamping the rim 1 with the spider 2.
