Abstract: In a three-component bearing, an intermediate layer 12 consisting of the harder bearing metal is arranged only in the axial edge areas of the bearing. In the highly stressed bearing center, the slide layer is supported directly by the steel-back bearing part. As a result, previously occurring fatigue fractures of the intermediate layer in the bearing center will be avoided.

Abstract: The invention relates to a slide bearing with two bearing shell halves which are held together during the installation by springy clamps. The clamps are formed from a band-shaped material piece having two bow-shaped legs bent over toward a side which are supported in inwardly inclined end areas at edges of the bearing shell halves. The seating of the clamp is thereby wobble-free, and more particularly both when the clamp is inserted with only one end into a mounting as also when both bearing shell halves are assembled which then are held together without play. The secure seating of the clamps is attained by multiple linearly- and areally-like supports of the clamps and by springy abutment at the inwardly bent end areas of the legs of the clamp, whereby axially acting forces result.

Abstract: A hardening process for a crankshaft which includes subjecting the crankshaft to a first induction hardening process to produce a hardened layer of a substantial thickness at all bearing locations and at all transitional points between the crank pins, journal pins and crank webs. Subsequently tempering the hardened zones of the crankshaft at the transitional points to a hardness value permitting a subsequent alignment of the crankshaft. Subjecting the crankshaft to a further induction hardening process to provide a second hardened layer only at the bearing locations which second layer has a depth which is less than the depth of the first hardened layer. The thus processed crankshaft is then subject to an expansion process to eliminate internal stresses therein.
