a zerkleinerungsvorrichtung axiallager and zerkleinerungsvorrichtung

摘要

An axial thrust bearing combination of a main shaft (1) of a gyratory crusher, and a gyratory crusher. The bearing combination comprises an intermediate plate (10) made of steel or a material having corresponding strength, the upper surface (11) of said intermediate plate (10) being a part of a concave or a convex spherical surface or a plane. The upper surface of the intermediate plate is opposed by the lower surface of the main shaft or a plate (12) attached thereto, formed as a correspondingly convex or concave part of a spherical surface or as a plane surface. The lower surface of the intermediate plate is opposed by a bearing surface (14) under the intermediate plate. The core part of the intermediate plate (10) is made of steel and at least one surface of it is plated with a layer of bearing material (11, 13), and the opposite surface (12, 14) against this layer of bearing material is a steel surface or a surface with corresponding strength characteristics.
