Problems solved by technology

Therefore, the increased number of notches brings about a reduction in the cross-section of each axial rod, which in turn brings about a higher risk of deflection

Embodiment Construction

[0041] To illustrate the invention, refer to figure 1 , the front-to-back orientation will be taken as the top-to-bottom axis without limitation.

[0042] In the following description, the same, similar or identical elements are denoted by the same reference numerals.

[0043] figure 1 An apparatus is described for mounting at least one winding 10 on a stack 14 of sheets 14 , which here is annular, by inserting a partial winding 10 into an axial recess 12 of the stack 14 .

[0044] This lamination 14 constitutes, for example, the stator body of a rotating electric motor in the form of a generator, such as a motor vehicle generator, which in one embodiment may be of the reversible type, thereby constituting a generator starter, in particular for starting hot.

[0045] The stator body is carried in a known manner by a casing which also serves as a support for the shaft fixed to the rotor, such as a claw rotor or an extended pole rotor, as described in document WO 02 / 054566. ...

Abstract

The present invention relates to a device for mounting a winding (10) and wedges (28) in slots (12) of a sheet stack (14) that comprises: an insertion block (26) of the winding (10) in the slots (12) that is mounted in a manner that enables it to axially move from a rear initial position situated behind the sheet stack (14); means (40) for mounting a retaining wedge (28) in each slot (12) with anaxial movement toward the front, these means being radially displaced by the insertion block (26) so that each wedge (28) is secured to the insertion block (26) while sliding forward with regard to the sheet stack (14).

Description

technical field [0001] The invention proposes a device for mounting windings and closing wedges into recesses in a stack of sheets of a rotating electrical machine. [0002] The invention more particularly proposes a device for mounting at least one winding and axial wedges into axial recesses of a stack of sheets, wherein each axial recess is at the front and rear axial end diameters of the stack of sheets Open to the face and include a groove opening on the inner cylindrical face of the stack of sheets, the apparatus comprising: [0003] - a block for inserting the windings into the recesses, said block being mounted to be displaceable coaxially with the stack from an initial rear position in which said insertion block is located axially in the stack the rear of the rear surface, and the block is contoured so as to deform the winding to introduce a portion of the winding into each notch during its forward movement; and [0004] - means for mounting in each notch a wedge fo...
