    摘要： In a tightening device for a drive belt in an internal combustion engine, particularly for a toothed belt in the camshaft gear with a tension roller supported on a pivoting lever comprising a tension spring acting upon the pivoting lever in the direction of tension and a blocking device opposing the motion of the pivoting lever, whose blocking element changes its position as a function of the temperature, the blocking element formed as an end stop by the free end (17) of a preferably plate shaped stop body (18) whose other end (19) is held in a fixed housing (1) wherein the end stop in the operating state of the internal combustion engine is disposed at a distance from the adjacent support face of the pivoting lever. The tightening device with the thermally adjustable end stop avoids a tooth jump, particularly in the case of long belts.

    摘要： The invention relates to thin-walled rolling bearings, such as needle bearings, which are produced without the removal of material and the outer rings of which form a structural unit and are produced from a cold-rolled strip. According to the invention, the outer rings are produced from a cold-formable, fully hardenable steel, a ratio of from 1:20 to 1:5 being set between their wall thickness and the diameter of the bearing needles, and the fully hardened wall having a core hardness of ≧600 HV and a surface hardness of ≧680 HV. The invention makes it possible for bearings to withstand higher static bearings than bearings made from conventional steels while taking up the same installation space.
