摘要： The present invention relates to a spring package (2) for use in a clutch and/or in a transmission, comprising a first supporting ring (4), a second supporting ring (6) which is arranged spaced apart (parallel) from the first supporting ring (4) in the axial direction, and a plurality of coil springs (8) arranged between the first supporting ring (4) and the second supporting ring (6) in distributed manner across the circumference thereof, wherein at least one of the supporting rings (4, 6) is formed from a sheet-metal strip (22) which is stamped and then bent into a ring shape and the ends of which are permanently connected to each other. Furthermore, the invention also relates to a method for producing a supporting ring (4, 6) for a spring package (2) according to the invention, comprising the following steps: stamping a sheet-metal strip (22) of predetermined length (l) and predetermined width (b), introducing spring holders (10; 68), introducing impressions on a longitudinal edge (26) of the sheet-metal strip (22) while forming a ring shape; and connecting the two axial ends.

摘要： The present invention relates to an oil scraper ring spring (1) for an oil scraper ring (3) comprising the oil scraper ring spring (1), an upper and a lower metal ring (21, 22) and provided for being mounted in an oil ring groove of a piston. The oil scraper ring spring (1) comprises a plurality of upper regions (5) and a plurality of lower regions (7) arranged in alternating manner in a circumferential direction so as to be spaced in an axial direction; connecting regions (9) each connecting the adjacent upper and lower regions (5, 7) to each other. Each of the upper and lower regions (5, 7) comprises: a nose section (13) disposed at the inner circumferential end and adapted to push the respectively abutting upper or lower metal ring (21, 22) radially outwardly, and having a through-opening (15); an abutment section (17) extending radially between the nose section (13) and the outer circumferential end and configured to have the respective upper metal ring (21) abutting thereon or the respective lower metal ring (22) abutting thereon; wherein the abutment section (17) has a recess (19) formed therein the depth of which, relative to the abutting area of the abutment section (17), increases in the radial direction towards the through-opening (15), and the width of which increases in the radial direction towards the through-opening (15); wherein the recess (19) in the abutment section (17) has substantially the shape of a half-funnel; wherein the half-funnel has an opening angle of 30° to 150°, in particular of 30° to 60°, or wherein the upper side edges of the recess (19) span an angular segment of 5-50°, in particular 5-15°; and wherein increasing the depth and width of the recess (19) radially inwardly together with the through-opening (15) serves to increase and accelerate the oil flow to the piston center.

摘要： A device for producing a spring wire includes a wire production apparatus which is designed such that a spring wire can be produced from a raw material, in particular by drawing; a checking unit which is designed such that the spring wire can be checked for flaws, in particular material flaws and surface flaws; and a laser marking unit which is designed such that defective regions of the spring wire, in particular regions of the spring wire having material and surface flaws, can be marked with a laser marking such that part of the surface of the spring wire can be removed or part of the surface of the spring wire can be tempered in such a manner that the color of the surface of the spring wire is changed in this part. The wire production apparatus is designed such that the spring wire can be guided past the checking unit and past the laser marking unit.
