PCT No. PCT/EP88/00165 Sec. 371 Date Oct. 2, 1989 Sec. 102(e) Date Oct. 2, 1989 PCT Filed Mar. 4, 1988 PCT Pub. No. WO88/07781 PCT Pub. Date Oct. 6, 1988.The method and the device are designed for assembling a stator (14), formed by a stack (16) of core plates and its windings (18), on to a respective head support (12) of a small, rotary electric machine, in a position concentric with a rotary shaft (20) mounted in the support. The method is of the type in which the periphery of one end face of the stack (16) of laminations rests on coplanar peripheral surfaces (22) of the support (12) which define a reference plane (P), a centering device (34) is interposed between the shaft (20) and the stack (16), and the stack (16) and the support (12) are held together by means of peripheral bolts (24) which are inserted in regions located in correspondence with the coplanar surfaces (22) of the support (12), are perpendicular to these surfaces (22), and are screwed into the support (12). Before the bolts (24) are tightened, the stack (16) is clamped between, at one end, the coplanar surfaces (22) and, at the other end, thrust members (52) applied to the other end face of the stack (16) in regions also corresponding with the regions in which the bolts (24) are inserted, with a clamping force normal to the reference plane (P) and at least substantially equal to that predetermined for tightening the bolts (24), the bolts (24) are then tightened with the predetermined tightening force, and the clamping force applied by the thrust members (52) is released. |
