Title (EN) A BUSH ASSEMBLY
(FR) ENSEMBLE DOUILLE
Abstract:
(EN) A bush assembly for receiving and coupling a transmission shaft to a transmission component, comprises a transmission component (2) having a hollow hub and an annular bush member (4, 5) having a tapered inner bore. A contractible, inner sleeve member (9) having a tapered outer surface and an inner bore adapted, in use, to receive the transmission shaft (3) is received in the tapered inner bore of the annular bush member (4, 5) with the tapered outer surface thereof contacting the tapered inner bore of the annular bush member. Engagement means (11, 13) ensure that there is no slippage between the transmission component (2) and the annular bush member (4, 5). Screws/bolts (8) allow the annular bush member to be tightened against the transmission component (2), thereby effecting contraction of the inner sleeve member (9) onto the shaft and engagement of the engagement means (11, 13) between the annular bush member (4, 5) and the transmission component (2).
(FR) Un ensemble douille, destiné à recevoir un arbre de transmission et à l'accoupler à un élément de transmission, comprend un élément de transmission (2) pourvu d'un moyeu creux et un élément en forme de douille annulaire (4, 5) présentant un passage interne conique. Un élément en forme de manchon interne (9) pouvant se contracter et présentant une surface externe conique et un passage interne adapté, lors de l'utilisation, à recevoir l'arbre de transmission (3), est logé dans le passage interne conique de l'élément en forme de douille annulaire (4, 5), sa surface externe conique entrant en contact avec le passage interne conique de l'élément en forme de douille annulaire. Des moyens d'engagement (11, 13) assurent qu'il n'y aura pas de glissement entre l'élément de transmission (2) et la douille annulaire (4, 5). Des vis/boulons (8) permettent à la douille annulaire d'être serrée contre l'élément de transmission (2), ce qui provoque la contraction de l'élément interne en forme de manchon (9) sur l'arbre, ainsi que l'engagement des moyens d'engagement (11, 13) entre l'élément en forme de douille annulaire (4, 5) et l'élément de transmission (2).
