Abstract: A camshaft adjusting device for an internal combustion engine is provided. A functionally reliable camshaft adjusting device designed for a long-lasting operation is obtained when the camshaft adjuster (13) has a lifelong lubrication located in the housing (28, 36, 37) sealed from the surrounding area be sealing covers (36, 37). The camshaft adjuster is not required to be mounted inside the cylinder head (33), but can be mounted as a separate unit on the cylinder head (33) of the internal combustion engine independent of the lubricating oil circuit. This expands, in particular, the range of possibilities for use of the camshaft adjuster (13) with a belt drive.

Abstract: The invention relates to a device for the finishing treatment of shaft workpieces, in particular crankshafts and camshafts. The device comprises a carrier, at least one jaw for exerting contact pressure on the workpiece, and a linear guide for guiding the jaw. The linear guide is supported by a transverse guide to form a cross guiding system which follows the rotational motion of the workpiece by revolving around its axis of rotation. The transverse guide contains a main carriage guided on the carrier. The main carriage is radially aligned with respect to the axis of rotation of the workpiece. The main carriage has a fork-shaped head facing towards the side of the workpiece. A guide rail for the linear guide is chucked between the between the legs of the fork-like head.
