Abstract

The process is for attaching sheet metal packets to the rotor cover of a hydraulic pump motor which has a block motor (2) with a turbine chamber (1) which has an input (10) and an output (11) for water. The turbine chamber is usually made of plastic and fixed to the block motor via a tightening screw. The block motor has a covered coil (4) attached to the metal packets (stator) and fixed on a cylindrical skirt (7) in which the rotor is free to rotate. The current in the coil creates a magnetic field which causes the rotor to move. The fixed turbine at one end of the shaft rotates and moves the water to the turbine chamber. The rotor/stator coupling requires that the stator (15) be fixed to the body (3) of the motor and be free to rotate without extra pieces. The cylindrical skirt (7) has the rotor into one or two wings (6) bent to the cylinder. The wings have a much greater length than the rotor. The folding is done by means of mechanical scissors and is effected hot or cold. USE - Hydraulic motor with stator wings with rotor cover.

Description

PROCEDE DE FIXATION D'UN PAQUET DE
TOLES DE MOTEUR
L'invention concerne un procédé de fixation d'un paquet de tôles sur l'enveloppe entourant le rotor d'un moteur, et en particulier un procédé de fixation du stator d'un moteur à aimant sur la jupe cylindrique entourant son rotor.METHOD FOR ATTACHING A PACKAGE OF
MOTOR SHEETS
The invention relates to a method of fixing a packet of sheets to the envelope surrounding the rotor of a motor, and in particular to a method of fixing the stator of a magnet motor to the cylindrical skirt surrounding its rotor.

Un moteur à aiment équipant par exemple, une pompe centrifuge, comporte un stator (fixe) commandé électriquement et agissant par couplage électromagnétique sur un rotor (mobile en rotation) entraînant la turbine de la pompe. Ce stator est constitué généralement d'un paquet de tôles qui vient se fixer en coulissant sur une jupe cylindrique entourant le rotor, le long de nervures situées sur cette jupe. A magnet motor fitted for example, a centrifugal pump, comprises an electrically controlled (fixed) stator and acting by electromagnetic coupling on a rotor (mobile in rotation) driving the pump turbine. This stator generally consists of a pack of sheets which is fixed by sliding on a cylindrical skirt surrounding the rotor, along ribs located on this skirt.

Ce procédé assure le maintien en rotation du stator par rapport à la jupe entourant le rotor. Le maintien du stator en translation par rapport à la jupe est en général assuré par un système de "clipage" pouvant être réalisé entre la carcasse de la bobine du moteur et le corps de ce moteur.This process keeps the stator in rotation relative to the skirt surrounding the rotor. Maintaining the stator in translation relative to the skirt is generally provided by a "clipping" system which can be produced between the carcass of the motor coil and the body of this motor.

L'utilisation de ces dispositifs de "clipage" lors de. la conception de tels moteurs pose des problèmes dans leur fabrication, notamment dans le fait de devoir utiliser des moules à tiroirs dans le cas de pièces en plastique. D'autre part, ces dispositifs sont souvent fragiles, coûteux et situés dans des parties du moteur où leur présence n'est pas souhaitable. The use of these "clipping" devices during. the design of such motors poses problems in their manufacture, in particular in the fact of having to use drawer molds in the case of plastic parts. On the other hand, these devices are often fragile, expensive and located in parts of the engine where their presence is not desirable.

L'invention permet de résoudre ce problème en utilisant des ailes issues de l'enveloppe du rotor du moteur, déjà existantes car utilisées pour le maintien en rotation du stator par rapport à cette enveloppe, pour le maintien en translation du stator grâce à leur forme particulière et à la déformation qu'elles subissent après l'emmanchement du stator sur l'enveloppe du rotor. The invention makes it possible to solve this problem by using wings from the envelope of the motor rotor, already existing because they are used for keeping the stator in rotation relative to this envelope, for keeping the stator in translation thanks to their shape. particular and to the deformation which they undergo after the fitting of the stator on the envelope of the rotor.

L'invention concerne donc un procédé de fixation d'un paquet de tôles sur une enveloppe entourant le rotor d'un moteur et est caractérisé en ce que les parties des ailes dépassant en longueur le stator emmanché sur l'enveloppe et maintenue en rotation grâce à ces ailes solidaires de l'enveloppe, sont rabattues sur l'enveloppe pour permettre la fixation en translation du stator par rapport à l'enveloppe. The invention therefore relates to a method of fixing a packet of sheets on a casing surrounding the rotor of a motor and is characterized in that the parts of the wings protruding lengthwise from the stator fitted on the casing and kept in rotation by to these wings integral with the envelope, are folded over the envelope to allow the stator to be fixed in translation relative to the envelope.

La présente invention sera mieux comprise et des avantages supplémentaires apparaitront à la description qui va suivre, illustrée par les figures suivantes
- la figure 1 représente une vue de derrière dans un plan perpendiculaire à son axe A d'un moteur pour lequel le procédé de fixation du stator selon l'invention a été utilisé
- la figure 2 représente une vue de côté dans un plan parallèle à l'axe A du même moteur.The present invention will be better understood and additional advantages will appear from the description which follows, illustrated by the following figures.
- Figure 1 shows a rear view in a plane perpendicular to its axis A of a motor for which the method of fixing the stator according to the invention has been used
- Figure 2 shows a side view in a plane parallel to the axis A of the same engine.

L'exemple illustrant l'invention représenté par les figures 1 et 2 concerne une pompe hydraulique à moteur à aimant, mais il est bien évident que l'invention s'applique à tous les types de moteurs d'entraînement nécessitant la fixation d'un paquet de tôles sur une pièce recouvrant le rotor. The example illustrating the invention represented by FIGS. 1 and 2 relates to a hydraulic pump with a magnet motor, but it is obvious that the invention applies to all types of drive motors requiring the fixing of a bundle of sheets on a piece covering the rotor.

Cette pompe comporte un bloc moteur 2 et une chambre turbine 1 sur laquelle est connectée une arrivée 10 et une sortie 11 d'eau. Cette chambre turbine 1, en général en plastique, est solidaire du bloc moteur 2 par l'intermédiaire de vis de serrage 12. Le bloc moteur 2 comporte une bobine encapotée 4 solidaire du paquet de tôles 5 (stator dans la suite du texte) par simple emboitement et coopérant avec celui-ci qui est fixé sur une jupe cylindrique 7 dans laquelle le rotor (non représenté sur la figure car à l'intérieur de la jupe 7) dont l'extrémité est solidaire de la turbine (non représentée car à l'intérieur de la chambre turbine 1) et libre en rotation. Le courant diffusé au travers de la bobine encapotée 4 dans le stator 5 engendre un champ magnétique qui entraîne le rotor aimanté en rotation. La turbine fixée à une extrémité de l'arbre entraîné ainsi en rotation, crée le flux d'eau au travers de la chambre turbine 1 de l'arrivée 10 à la sortie 11. This pump comprises a motor unit 2 and a turbine chamber 1 to which is connected an inlet 10 and an outlet 11 for water. This turbine chamber 1, generally made of plastic, is secured to the engine block 2 by means of clamping screws 12. The engine block 2 comprises a wrapped coil 4 secured to the sheet pack 5 (stator in the text below) by simple interlocking and cooperating with it which is fixed on a cylindrical skirt 7 in which the rotor (not shown in the figure because inside the skirt 7) whose end is secured to the turbine (not shown because inside the turbine chamber 1) and free to rotate. The current diffused through the wrapped coil 4 in the stator 5 generates a magnetic field which drives the magnetized rotor in rotation. The turbine fixed to one end of the shaft thus driven in rotation, creates the flow of water through the turbine chamber 1 from the inlet 10 to the outlet 11.

Le couple rotor/stator nécessite, pour un bon fonctionnement du moteur, que le stator 15 soit fixé sur le coprs 3 du moteur et le toro libre en rotation et cela à moindre coût et sans ajout de pièces supplémentaires. La présente invention le permet par un procédé simple. The rotor / stator couple requires, for a good functioning of the engine, that the stator 15 is fixed on the body 3 of the engine and the free toro in rotation and this at lower cost and without adding additional parts. The present invention allows this by a simple method.

La jupe cylindrique 7 contenant le rotor comporte une ou deux ailes 6 grâce auxquelles le stator emmanché sur cette partie cylindrique 7 est maintenue en rotation. Ces ailes 6 ont une longueur plus grande que celle du rotor afin de déborder de celui-ci lorsqu'il est emmanché en butée. Leurs parties débordantes 8 sont abattues sur la partie cylindrique 7 et permet ainsi que le stator 5 soit maintenu fixé en translation par rapport à la partie cylindrique 7, le bord 9 du stator 5 étant en butée sur la partie d'ailes rabattues 8.The cylindrical skirt 7 containing the rotor has one or two wings 6 by which the stator fitted on this cylindrical part 7 is kept in rotation. These wings 6 have a length greater than that of the rotor in order to extend beyond it when it is fitted in abutment. Their projecting parts 8 are brought down on the cylindrical part 7 and thus allows the stator 5 to be kept fixed in translation relative to the cylindrical part 7, the edge 9 of the stator 5 being in abutment on the part of the folded wings 8.

Ce rabattement peut être effectué à l'aide d'un ciseau mécanique qui coupe les ailes 6, le rebord 9 du stator 5 sert alors de ciseau fixe lors de cette opération de rabottement. This folding can be done using a mechanical chisel which cuts the wings 6, the flange 9 of the stator 5 then serves as a fixed chisel during this planing operation.

Cette opération peut être effectué à chaud ou à froid. This operation can be carried out hot or cold.

Ce rabattement peut aussi être une simple déformation à chaud des ailes 8, le bord 9 du stator 5 pouvant alors servir de limites à la déformation possible des ailes 6 dans leurs parties 8. This drawdown can also be a simple hot deformation of the wings 8, the edge 9 of the stator 5 can then serve as limits to the possible deformation of the wings 6 in their parts 8.

La présente invention s'applique à tous les moteurs synchrones de machines à laver, et plus généralement, à tous les types de moteurs comportant un rotor protégé.  The present invention applies to all synchronous motors of washing machines, and more generally, to all types of motors comprising a protected rotor.
