Abstract

The rotor is assembled from two halves, with meeting faces perpendicular to the axis of rotation. The two halves have cut-outs near their periphery to accommodate the field winding. The left hand half of the rotor has a substantial projection which fits into a central hole in the right hand half in order to join the two halves of the rotor, the end of the projection being flattned to firmly fix the joint. The left half of the rotor has an projection formed on it to act as the pulley shaft, while a bearing is fitted into the end of the right half to accept a stub shaft fixed to the stator. The rotor is manufactured from forged steel and dispenses with the need for a shaft.

Description

POLES DE ROTOR D'ALTERNATIUR EN ACIER FORGE AUTO-ASSEMBLABLES
La présente invention concerne le rotor d'alternateur destiné à la production d'électricité sur les véhicules automobiles de tous types.
Dans tous les types de rotor connus, la liaison des 2 pinces principales appelées selon les fabricants d'alter- nateurs t pôles de rotor, roue polaire, épanouissement, cloche polaire etc... est assurée par un arbre cannelé emmanché à la presse et bloqué eu pas par sertissage de chaque p8le de rotor. Les figures 1 et 2 représentent les deux versions possibles connues.Dans ce type de rotor, cette pièce ajoutée qu'est arbre sert & la mise en rotation du rotor par l'intermédiaire d1une poulie et de deux roulements à billes, ainsi que souvent à la fixation du collecteur pour l'excitation de la bobine. Ce type de liaison est comateux, encombrant et source d'ennuis à l'assemblage $(déformation, flexion de l'arbre, grippage).
SELF-ASSEMBLING FORGED STEEL ALTERNATIUR POLES
The present invention relates to the alternator rotor intended for the production of electricity on motor vehicles of all types.
In all types of known rotor, the connection of the 2 main clamps called according to the manufacturers of alternators t rotor poles, pole wheel, spreading, pole bell etc ... is ensured by a splined shaft fitted to the press and blocked or not by crimping each rotor pole. Figures 1 and 2 show the two known possible versions. In this type of rotor, this added part which is a shaft is used for the rotation of the rotor by means of a pulley and two ball bearings, as well as often fixing the collector for excitation of the coil. This type of connection is comatose, bulky and a source of trouble for assembly $ (deformation, bending of the shaft, seizure).

Le rotor selon l'invenion, figures 3, 4, 5 permet la suppression de la pièce de liaison qu'est arbre. En effet, les deux pièces principales que sont les pôles de rotor, pCle gauche 2 et pôle droit 3 suffisent à eux seuls pour assurer dans de bonnes conditions leur liaison par rivetage, et leur mise en rotation par l'intermédieire d'une poulie 4 qui sera directement fixée sur le pôle gauche 2 (Voir figure 3 et 4).Un tel assemblage, hormis le gain d'une pièce conteuse (l'arbre), permet de réduire l'encombrement du rotor et par là même de l'alternateur en plaçant le roulement à billes 9 (figure 3) ou la bague en bronze 9 (figure 4)directement à l'intérieur du pSle droit 3 ce mOme pôle droit 3 pouvant servir de fixation au collecteur 7. Cette nouvelle conception des pôles de rotor gauche 2 et droit 3, ainsi que leur liaison par rivetage,simplifie l'assemblage du rotor, en réduit le cotit, doit améliorer l'équilibrage du rotor. The rotor according to the invention, Figures 3, 4, 5 allows the removal of the connecting piece that is shaft. Indeed, the two main parts that are the rotor poles, left pCle 2 and right pole 3 alone are sufficient to ensure in good conditions their connection by riveting, and their rotation by the intermediary of a pulley 4 which will be directly fixed on the left pole 2 (See Figure 3 and 4). Such an assembly, apart from the gain of a storytelling part (the shaft), makes it possible to reduce the bulk of the rotor and thereby alternator by placing the ball bearing 9 (figure 3) or the bronze ring 9 (figure 4) directly inside the straight pole 3 this same straight pole 3 can be used to fix the manifold 7. This new design of the poles left rotor 2 and right rotor 3, as well as their connection by riveting, simplifies the assembly of the rotor, reduces its cost, must improve the balancing of the rotor.

La figure 1 représente en coupe une variante des rotors tels qu'ils sont généralement conçus. Une bobine 1 est montée sur un noyau 2 source de flux magnétique pour les piles gauches 3 et droit 4. Dans cet ensemble, un arbre 5 est emman ohé à la presse, et cet arbre qui sert de liaison transmet le couple rotation par l'intermédiaire d'une poulie 6 immobi lisée par une clavette 7 et bloquée par rondelle 8 et écrou 9. Sur l'arbre, sont montés le collecteur 10 pour l'excita- tion électrique de la bobine et les roulements a' billes 11 et 12 pour la rotation. Deux entretoises 13 et 14 positionnent le roulement à billes côté poulie. Figure 1 shows in section a variant of the rotors as they are generally designed. A coil 1 is mounted on a core 2 source of magnetic flux for the left 3 and right batteries 4. In this assembly, a shaft 5 is press-fitted, and this shaft which serves as a connection transmits the rotating torque by the intermediate of a pulley 6 immobilized by a key 7 and locked by washer 8 and nut 9. On the shaft, are mounted the manifold 10 for the electrical excitation of the coil and the ball bearings 11 and 12 for rotation. Two spacers 13 and 14 position the ball bearing on the pulley side.

La figure 2 représente en coupe la deuxième variante des rotors tels qu'ils sont généralement conçus. Une bobine 1 est montée sur les piles gauches 3 et droits 4 à demi-noyau incorporé0 Dans cet ensemble, un arbre 9 est emmanché à la presse et cet arbre qui sert de liaison aux pôles transmet le couple de rotation par lBintermédiaire d'une poulie 6 immobilisée par une clavette 7 et bloquée par rondelle 8 et écrou 9. Sur arbre sont montés le collecteur 10 pour l'excitation électrique de la bobine et les roulements à billes 11 et 12 pour la rotation, les entretoises 13 et 14. Figure 2 shows in section the second variant of the rotors as they are generally designed. A coil 1 is mounted on the left 3 and right batteries 4 with incorporated half-core 0 In this assembly, a shaft 9 is press fitted and this shaft which serves as a connection to the poles transmits the torque via the pulley 6 immobilized by a key 7 and locked by washer 8 and nut 9. On the shaft are mounted the manifold 10 for the electrical excitation of the coil and the ball bearings 11 and 12 for rotation, the spacers 13 and 14.

L'immo- bilisation de la poulie est assurée en rotation par crantage de la poulie et du pale 2, et son blocage est assuré par la rondelle 5 et l'écrou 6. Le collecteur 7 sera fixé sur le pa- le 3 et la rotation sera assurée par les roulements à billes 8 et 9. Figure 3 shows in section the first variant of the rotor according to the invention. A coil 1 is mounted on the left blades 2 with half-core and shaft incorporated and straight 3 with half-core and bearing incorporated. A pulley 4 directly transmits the torque to the stacks 2 and 3. The immobilization of the pulley is ensured in rotation by notching the pulley and the blade 2, and its blocking is ensured by the washer 5 and the nut 6. The collector 7 will be fixed on the pallet 3 and the rotation will be ensured by the ball bearings 8 and 9.
