Apparatus and method for machining a bearing seat or a bearing journal supported therein

摘要

An apparatus for at least intermittent metal-cutting machining of a support face of a bearing seat (5) of a concentrically guided shaft (3) with the bearing (4) dismantled is proposed, having at least one cutting tool (1) that is rotationally movable, in particular on a shaft (3) slidingly supported by bearing shells (4), such as a crankshaft of a large two-cycle diesel motor, in the gap created between the bearing seat (5) and a bearing journal (3) received in the bearing seat by dismantling of the bearing (4). The apparatus is distinguished in that a securing device (2) for securing the cutting tool (1) to the bearing journal (3) is provided, which is arranged such that in machining of the support face of the bearing seat (5), the bearing journal (3) acts as a rotating tool holder, and the cutting tool (1) is guided in a purely rotational cutting motion along the support face of the bearing seat (5), and the securing device (2), for re-releasable securing of the cutting tool (1) in a manner free of residue and nondestructively, is arranged in force- and/or material-locking fashion and includes an adhesive layer and/or at least one hose clamp. A corresponding apparatus for machining a support face of a bearing journal (3) of a concentrically guided shaft (3) with a dismantled bearing (4), and a method for machining the support face of the bearing seat or the bearing journal with an apparatus, are also proposed.

主权项

1. An apparatus for chip removal machining of a support face of a bearing seat of a concentrically guided shaft, with a bearing of said bearing seat dismantled on a shaft supported in a sliding fashion with bearing shells, having:
at least one cutting tool, rotationally movable relative to the bearing seat along the support face of the bearing seat in a gap, created by the bearing, between the bearing seat and a bearing journal received in the bearing seat; and a securing device for securing said cutting tool to the bearing journal arranged such that in the maching of the support face of the bearing seat, said bearing journal acts as a rotating tool holder, and said cutting tool is guided in a rotational cutting motion along the support face of said bearing seat, wherein: said securing device, re-releasably secures said cutting tool on said bearing journal free of residue and nondestructively, and is arranged in one of: force-and material -locking fashion, and includes an adhesive layer or at least one hose clamp, for joining said tool to the support/face on said bearing journal.
