Title
(EN) APPARATUS AND METHODS FOR INSERTING COILS AND COVER WEDGES IN THE SLOTS OF DYNAMOELECTRIC MACHINE CORES
(FR) APPAREIL ET PROCÉDÉS PERMETTANT D'INTRODUIRE DES SPIRES ET DES COINS DE PROTECTION DANS LES FENTES DE NOYAUX DE MACHINES DYNAMOÉLECTRIQUES
Abstract
(EN)
An apparatus for inserting coil branches (13a, 13b) of pre-wound wire coils and cover wedges (14) into slots (11) of a dynamoelectric machine core (10), comprises a first pusher assembly (50) having an insertion stroke for advancing through the bore (10') to insert the coil branches into the slots (11) and a second pusher assembly (96, 97) configured to push the cover wedges (14) into the slots (11) along the coil branches. The second pusher assembly comprises first and second- movable supports (96, 97) for pushing first and second groups of wedges (30, 32, 33, 35, 36, 38) into respective slots (11) during a same insertion stroke. The apparatus is provided with radial arms (5-6', 57', 58') moveable in the radial direction (R) of the core (10) for entering the slots (11) to push coil branches (26”) towards the bottom of the slots (11). At least one form member (131-136, 141-143) may be provided for impeding the insertion of a branch of a coil in the respective portion of the slot during at least one insertion stroke of the first pusher assembly (50).
(FR)
L'invention concerne un appareil permettant d'introduire des branches de spires (13a, 13b) de fil pré-enroulé et des coins de protection (14) dans des fentes d'un noyau de machine dynamoélectrique (10), qui comprend un premier ensemble pousseur (50) possédant une course d'introduction permettant d'avancer à travers l'alésage (10') afin d'introduire les branches de spire dans les fentes (11) et un second ensemble pousseur (96, 97) agencé de façon à pousser les coins de protection (14) dans les fentes (11) le long des branches de spire. Le second ensemble pousseur comprend un premier et un second support mobile (96, 97) destinés à pousser un premier et un second groupe de coins (30, 32, 33, 35, 36, 38) dans des fentes respectives (11) pendant une même course d'introduction. Cet appareil est pourvu de bras radiaux (56', 57', 58') mobiles dans le sens radial (R) du noyau (10) pour pénétrer les fentes (11) afin de pousser des branches de spire (26'') vers le fond des fentes (11). Au moins une forme (131-136, 141-143) peut être prévue pour empêcher l'introduction d'une branche de spire dans la partie respective de la fente pendant au moins une course d'introduction du premier ensemble pousseur (50).
