| 摘要 |
The invention relates to a device (1) for grinding an external sleeve surface (3) on a rotationally symmetrical body (2), in particular for grinding a roller on a paper machine, comprising a support frame (11), displaceable along the external sleeve surface (3) of the body (2) to which a driven belt grinder (12) is fixed and several pivoted running rollers (14), laterally spaced in the circumferential direction of the body (2), resting on the external sleeve surface (3) of the body (2), whereby a rapid and positionally exact grinding of the body (2) is guaranteed, without having to make the body for machining in a paper mill freely accessible. The above is achieved, whereby a fixed thrust bearing (21) is provided for the external sleeve surface (3) to be machined, an adjuster (22), fixed to the support frame (11), is fitted between the above and the thrust bearing (21), which is supported on the thrust bearing (21). The pressure acting on the external sleeve surface (3) and/or the engagement of the belt grinder (12) may be adjusted depending upon the irregularity of the external sleeve surface (3) and/or the measured eccentricity of the body (2), by means of the adjuster (22). |
