Method for centerless grinding of shaft components

Abstract

The invention provides a method for the centerless grinding of shaft parts (9), in particular of tubes for assembled camshafts, in the case of which the shaft part (9) which is to be ground, and has axial centering portions (11) on its end sides, is ground in rotatably driven fashion, in a manner which is customary in centerless grinding, in a gap between the grinding wheel (1) and regulating wheel (2). The grinding wheel (1) and regulating wheel (2) have a width which corresponds at least to the length of the shaft part (9). The shaft part (9) is ground in its end regions (28) first of all concentrically in relation to the centering portions (11), and this produces ground formations concentrically in relation to the centering portions (11). This is followed by the grinding of the intermediate region (29), which is located between the end regions (28), and then by the entire shaft part (9) being ground to size in a dimensionally accurate and dimensionally stable manner on the basis of the ground formations at the end regions (28) of the shaft part (9), said formations being made concentrically in relation to the centring portions (11) and resting on a support (16). In order to implement the method, the invention provides an appropriately dimensioned grinding-wheel and regulating-wheel pair (1, 2) in a centreless grinding machine, in the case of which regions of increased diameter, i.e. a respective profiling, are / is provided in the side regions of said machine in order to grind the end regions (28) of the shaft part (9).

Description

technical field [0001] The present invention relates to a method for centerless grinding of shaft components, in particular constructed or manufactured camshaft tubes; The disk and the adjusting disk form a counterpart, wherein the shaft part has a centering hole at the end that runs concentrically with respect to the longitudinal axis of the workpiece. Background technique [0002] As a rule, in centerless grinding, the workpiece lies on a mounting scale between the grinding disc and the setting disc and is cut off in rotation. In this case, the adjusting disc and the grinding disc form a grinding gap, which is closed below by the mounting scale to the extent that the shaft-shaped workpiece comes into linear contact with the setting disc, the grinding disc and the support surface on which the scale is mounted. closed and thus fixed in position with respect to its longitudinal axis and rotates. The purpose of this configuration is to remain as stationary as possible in pos...
