A device for aligning the refining disc of a refining apparatus, in which refining apparatus lignocellulose-containing material is disintegrated and refined, which device is intended to be arranged in a support (701) for the axle package of the refining apparatus, the supporting (701) resting on a ground surface, which axle package comprises the rotary refining disc of the refining apparatus, a rotation axle to which the rotary refining disc is attached, and a bearing housing (702) in which the axle is journalled by means of bearings arranged in the bearing housing (704). The device comprises a first wedge-shaped member (703), which is slidable in a direction along said ground surface, and a second wedge-shaped member (704) provided between the first member (703) and the bearing housing (702) of the axle package, which second member (704) is slidable in a direction transverse to the sliding direction of the first member (703), and the first member (703) when displaced in its sliding direction is arranged to displace the second member (704). The device comprises a control device for displacing the first member (703) and a support means (706), on which the bearing housing (702) rests, which is provided between the second member (704) and the bearing housing (702) and arranged to engage with a to the support means (706) comple- mentary recess (707) of the bearing housing (702). The support means (706) has a convex contact surface (708) against the recess (707) of the bearing housing (702), and the convex contact surface (708) of the support means (706) is dis- placeable in relation to the surface of the complementary recess (707) of the bearing housing (702). Support and refining apparatus comprising said device.

La présente invention concerne un dispositif pour aligner le disque de raffinage d'un appareil de raffinage, dans lequel appareil de raffinage un matériau qui contient de la lignocellulose est désintégré et raffiné, lequel dispositif est prévu pour être agencé dans un support (701) pour le boîtier d'axe de l'appareil de raffinage, le support (701) reposant sur une surface du sol, lequel boîtier d'axe comprend le disque de raffinage rotatif de l'appareil de raffinage, un axe de rotation auquel le disque de raffinage rotatif est fixé, et un corps de palier (702) dans lequel l'axe est supporté de façon pivotante au moyen des paliers agencés dans le corps de palier (704). Le dispositif comprend un premier élément en forme de cale (703) qui peut coulisser dans une direction le long de ladite surface du sol, et un second élément en forme de cale (704) prévu entre le premier élément (703) et le corps de palier (702) du boîtier d'axe, lequel second élément (704) peut coulisser dans une direction transversale à la direction de coulissement du premier élément (703), et le premier élément (703), lorsqu'il est déplacé dans sa direction de coulissement, est agencé pour déplacer le second élément (704). Le dispositif comprend un dispositif de commande pour déplacer le premier élément (703) et un moyen de support (706), sur lequel repose le corps de palier (702), qui est prévu entre le second élément (704) et le corps de palier (702) et agencé pour entrer en prise avec un évidemment complémentaire (707) du moyen de support (706) du corps de palier (702). Le moyen de support (706) possède une surface convexe (708) contre l'évidement (707) du corps de palier (702), et la surface de contact convexe (708) du moyen de support (706) peut être déplacée par rapport à la surface de l'évidement complémentaire (707) du corps de palier (702). La présente invention concerne un support et un appareil de raffinage comprenant ledit dispositif.
