Title
(EN) RETENTION SYSTEM AND METHOD FOR VANE RING ASSEMBLY
(FR) SYSTÈME DE RETENUE ET PROCÉDÉ POUR UN ENSEMBLE DE GRILLES À AUBES
Abstract
(EN)
A variable geometry turbocharger includes a vane pack having rotatable vanes constrained by a pair of vane rings held together by a plurality of pins. A first end of each pin can be configured with a head. Each pin is received in a pair of aligned apertures in the vane rings such that the head of each pin engages one of the vane rings. A second end of each pin is deformed (e.g., by orbital riveting) such that it engages the other vane ring. Thus, a clamp load is applied to the vane rings, which can control the parallelism and distance between the vane rings so that the vanes can rotate with a minimum clearance without jamming. Also, the pins can maintain vane axle apertures in the vane rings in the correct angular position relative to each other. Such a vane pack configuration can reduce process time and cost.

L'invention concerne un turbocompresseur à géométrie variable comprenant un ensemble d'aubes ayant des aubes rotatives retenues par une paire de grilles à aubes retenues ensemble par une pluralité de broches. Une première extrémité de chaque broche peut être configurée avec une tête. Chaque broche est reçue dans une paire d'ouvertures alignées dans les grilles à aubes de sorte que la tête de chaque broche entre en prise avec l'une des grilles à aubes. Une seconde extrémité de chaque broche est déformée (par exemple, par rivetage orbital) de sorte qu'elles entrent en prise avec l'autre grille à aubes. Ainsi, une charge de serrage est exercée sur les grilles à aubes, servant à contrôler le parallélisme et la distance entre les grilles à aubes de sorte que les aubes peuvent tourner avec un dégagement minimum sans grippage. De plus, les broches peuvent maintenir les ouvertures d'essieu d'aubes dans les grilles d'aubes dans une bonne position angulaire les unes par rapport aux autres. Une telle configuration d'un ensemble d'aubes peut réduire le coût et le temps du processus.
