Abstract

The subject matter of the present invention is a torsional spring which is preferably configured as a torsion bar or helical spring from a spring wire comprising fibre composite material. Said torsional spring has a plurality of layers (Sj) of fibre reinforcement which are impregnated with a matrix material, wherein the layers have fibres which are subjected to tensile loading and fibres which are subjected to compressive loading. It is characteristic that the at least one group (Gk) which is subjected to compressive loading has a lower group stiffness than that group (Gk) with the highest group stiffness which is subjected to tensile loading. Furthermore, a method for designing a torsional spring from fibre composite material is disclosed.

Abstract

The invention relates to a torsion spring, which is preferably designed as a bar spring or coil spring made from spring wire composed of fiber composite material. Said torsion spring has a plurality of layers (Sj) of fiber reinforcement, which are impregnated with a matrix material, wherein the layers have fibers that are loaded in tension and fibers that are loaded in compression. The torsion spring is characterized in that groups (Gk) of layers (Sj) of the same loading direction exist, and the group stiffness of at least two groups, as viewed from the inside out, differs. The invention further relates to a method for designing a torsion spring composed of fiber composite material.

Abstract

The invention relates to a manufacturing system for producing products consisting of cylindrical metal bars (S) with units which are arranged consecutively when seen in the direction of travel of the metal bars and which form a processing line, comprising an induction bar-heating device (6) for heating the metal bars (S), a cross rolling system (7) for cross-rolling the heated metal bars (S), and a transporting device (10) which adjoins the cross rolling system (7) for further transporting the metal bars (S). The aim of the invention is to provide such a manufacturing system with which damage to the surface of the metal bars is prevented to the greatest possible extent. According to the invention, this is achieved in that the transporting device (10) has at least one drivable rotating guide (20) which can be driven in a rotational manner such that the rotating guide (20) rotates at a circulating speed which is adapted to a circumferential speed of the metal bars (S) that rotate about the metal bar longitudinal axes due to the cross rolling process.
