Title
(EN) HUB ASSEMBLY FOR WATER JET PROPULSION UNIT
(FR) MOYEU POUR UNITE DE PROPULSION PAR JET D'EAU
Abstract
(EN)
Hub assembly for the journalling of an impeller (4) or drive shaft end (3) in the pump housing (2) of a water jet propulsion unit for propulsion of a vessel. The hub assembly forms a separate, integrated assembly (6) which as a single unit can be assembled and dismounted from the stern without requiring the pump housing, impeller or drive shaft to be removed from the vessel. The hub assembly is joined together by means of a tightening nut (15), screwed onto a sleeve (9), with an inwardly positioned bearing plate (16) axially holding the sleeve in a bearing housing (8) while concurrently clamping the bearings (10, 11) between said bearing plate and a radially extended flange (17), arranged in the front end of the sleeve, so that the bearing housing, the bearings and the sleeve form a separate, integrated unit.
(FR)
La présente invention concerne un moyeu destiné à supporter une roue (4) ou l'extrémité de l'arbre (3), dans le corps de pompe (2), d'une unité de propulsion d'un navire par jet d'eau. Le moyeu forme un ensemble séparé et intégré (6) qui, en tant qu'unité isolée, peut être assemblé et démonté de l'arrière sans qu'il soit nécessaire de démonter du navire le corps de pompe, la roue ou l'arbre. Le moyeu est assemblé au moyen d'un écrou de serrage (15) vissé sur un manchon (9), avec une plaque-support (16) placée à l'intérieur et qui maintient axialement le manchon dans le boîtier (8) des roulements tout en serrant les roulements (10, 11) entre la plaque-support et une bride radiale (17), placée à l'extrémité avant du manchon, de telle sorte que le boîtier des roulements, les roulements et le manchon forment une unité distincte et intégrée.
