This invention concerns a shock absorbing device (10) for a shaft (1) in rotation around a rotation axis parallel to a direction (A). The said shock absorbing device (10) comprises a support (11), a plate (12), a bearing (13) and the means to tighten (15). The said support (11) is fixed and features a first opening (111), the said plate (12) features a second opening (121) and the said bearing (13) features a third opening (131). The said shaft (1) simultaneously crosses the said first, second and third openings (111, 121, 131) with respectively first, second and third radial play, the said third radial play being less than the said first and second radial plays. The said bearing (13) is mobile relative to the said support (11) in a plane perpendicular to the said direction (A). The said means to tighten (15) pushes the said plate (12) against the said bearing (13) and the said bearing (13) against the said support (110).
La présente invention concerne un dispositif d'amortissement (10) pour un arbre (1) en rotation autour d'un axe de rotation parallèle à une direction (A). Ledit dispositif d'amortissement (10) comporte un support (11), une plaque (12), un plateau (13) et un moyen de serrage (15). Ledit support (11) est fixe et muni d'une première ouverture (111), ladite plaque (12) étant munie d'une seconde ouverture (121) et ledit plateau (13) étant muni d'une troisième ouverture (131). Ledit arbre (1) traverse simultanément lesdites première, seconde et troisième ouvertures (111,121,131) avec respectivement un premier jeu radial, un second jeu radial et un troisième jeu radial, ledit troisième jeu radial étant inférieur auxdits premier et second jeux radiaux. Ledit plateau (13) est mobile par rapport audit support (11) dans un plan perpendiculaire à ladite direction (A). ledit moyen de serrage (15) plaquant ladite plaque (12) contre ledit plateau (13) et ledit plateau (13) contre ledit support (11).
