VIBRATION DAMPING DEVICE COMPRISING A COLLAR ABUTABLE ON A DAMPING UNIT

The invention relates to a damping device, in particular for mounting a support platen (10), comprising a cylindrical damping unit (12) of the main axle (A) which comprises cylindrical top (20s) and lower (20i) radial collets each of which is received by the side of a horizontal plate (18) of the platen (10), wherein the platen (10) comprises at least one cylindrical collar (26s, 26i) which is carried by the horizontal plate (18) and extends oppositely to the external cylindrical surface (20e) of the associated collet (20s, 20i). Said invention is characterised in that the collar (26s, 26i) is provided with an internal concave cylindrical surface (26a) which is radially abuts on the external cylindrical surface (20e)of the collet (20s, 20i) in at least one generally horizontal direction. La invencion se relaciona con un dispositivo de amortiguamiento, en particular para montar una platina de soporte (10) que comprende una unidad de amortiguamiento cilindrica (12) del eje principal (A) que comprende boquillas radiales superior (20s) e inferior (20i) cilindricas cada una de las cuales es recibida por el lado de una placa horizontal (18) de la platina (10), en donde la platina (10) comprende al menos un collarin cilindrico (26a, 26i) que es portado por la placa horizontal (18) y se extiende opuesto a la superficie cilindrica externa (20e) de la boquilla asociada (20s, 20i); dicha invencion esta caracterizada porque el collarin (26s, 26i) esta provisto con una superficie cilindrica concava interna (26a) que se apoya radialmente sobre la superficie cilindrica externa (20e) de la boquilla (20s, 20i) en al menos una direccion generalmente horizontal.
