Definitions
- the present invention relates to a method of assembling a collector on the shaft of a rotor of a rotating electrical machine, as well as the adapted shaft and collector.
- the invention also relates to a rotor comprising such shaft and collector, and a rotary electric machine equipped with such a rotor.
- a manifold having slip rings for supplying power to one or more windings of a rotor of a rotating electrical machine is generally embodied as a separate piece which is then attached to one end of the rotor shaft .
- the mechanical stresses applied to the collector during the assembly must be low because the material of the collector, in particular plastic, is generally very brittle;
- a method such as that described in the patent application FR2514209 would probably improve the bonding between the collector and the knurled portion of the outside of the shaft by interposing an impregnating resin.
- the object of the present invention is therefore to overcome the above drawbacks by proposing a method of assembling a collector on the shaft of a rotor, by press fitting on an externally knurled portion of one end of the rotor. shaft, remarkable in that this fitting is made so that the outer knurled portion remains located outside a first portion of the collector supporting slip rings.
- an internally knurled portion of the manifold located substantially outside this first portion is advantageously force-fitted on a smooth portion outside the end of the shaft.
- a collector adapted to the implementation of the method according to the invention, and of the type of those made by overmolding insulating material on electrically conductive elements comprising slip rings, is remarkable in that it comprises an internally located knurled portion essentially outside a first portion of the manifold that supports the slip rings.
- this manifold has a smooth portion internally outside its knurled portion internally.
- a shaft of a rotor adapted to the implementation of the method according to the invention is also remarkable in that it comprises an end having an externally knurled portion adapted to cooperate with a second portion of a collector not supporting rings. collectors of this collector.
- the end of this shaft preferably has a smooth portion externally outside the knurled portion externally.
- the invention also relates to a rotor comprising a collector and a shaft as described above, and a rotary electrical machine comprising such a rotor.
- Figure 1 illustrates the method of assembly on the shaft of a rotor according to the invention.
- Figure 2a is an end view of the end of a shaft of a rotor according to the invention.
- Figure 2b is an end view of a collector according to the invention.
- Figure 3 is an axial sectional view of the collector and the end of the rotor shaft according to the invention.
- Figure 1 shows the proposed solution of assembling a shaft 2 and a collector 3 partially knurled.
- the end 4 of the shaft 2 has, on the side 5 of the connections of the excitation winding of the rotor, an externally knurled portion 6.
- these teeth regularly distributed on the periphery of the end 4 of the axis 2 with an outside diameter of about 5.6 mm, are 36 in number and have a height of about 0. , 1 mm.
- the externally knurled portion 6 extends axially only about
- This externally smooth portion 7 does not deform the collector 3 during the assembly 1, and in particular the slip rings 8, insofar as, according to the method of the invention, the knurled part externally 6 remains located outside of a first portion A of the collector 3 which supports these rings 8.
- Maintaining the collector 3 on the end of the shaft 2 is ensured by the deformation of the material of the collector 3, such as plastic, less hard than the material of the shaft 2, generally steel, at the level of a second portion B of the manifold 3 which does not support the slip rings 8.
- An additional maintenance of the collector 3 on the end 4 of the axis 2, to avoid play, is obtained by providing the collector 3 with an internally knurled portion 9 located essentially outside the first portion A of the collector 3 and at a third extremal portion C.
- the end view of the collector 3 of FIG. 2a clearly shows the tooth-shaped profile of the axial grooves constituting the knurling 9.
- these teeth regularly distributed on the periphery of the axial bore 10 with an internal diameter of about 5.6 mm, are 36 in number and have a depth of about 0.1 mm.
- the internally knurled portion 9 extends axially only about 2 mm, in this particular embodiment of the invention. Most of the axial bore 10, to the electrically conductive elements 1 1, is smooth.
- the internal diameter of the axial bore of the manifold 3 is advantageously substantially identical to the outer diameter of the end 4 of the rotor axis 2, that is to say about 5.6 mm in this embodiment. . In this way, guidance is obtained without effect on the shape of the slip rings 8.
- the advantage of the method of assembling a manifold 3 on a shaft 2 according to the invention, and collector 3 and shaft 2 adapted, is that, thanks to the partial knurling on the shaft 2 and on a tip C of the collector 3, a good maintenance of the collector 3 is assured without significant deformation of the slip rings 8.
- slip rings 8 being less deformed during the assembly operation, a rotating electric machine provided with a rotor comprising a collector 3 and a shaft 2 assembled by the method according to the invention will have a longer service life because the forces and vibrations caused by ovalization of the slip rings 8 will be lower and therefore the wear of the brushes is reduced.
