摘要： Method of manufacturing an endless ring (10) for use in a push belt for continuously variable transmissions, in which the material (M1; M2) of the ring (10) is a maraging steel (Ml; M2) and in which said ring (10) is subjected to a heat treatment in a heating chamber (1; 6) under the presence of nitrogen gas (N2) for realising a core hardening of the ring material (M1; M2) through ageing and to a heat treatment in a heating chamber (2; 6) under the presence of ammonia gas (NH2) for realising a case hardening of the ring material (Ml; M2) through nitriding. The said heat treatments are performed in a combined hardening process, simultaneously and in the same heating chamber (6), whereby the composition of the maraging steel used (M2) is selected to have a required processing time (H) of the ageing heat treatment that is equal to that of the nitriding heat treatment.

摘要： Drive belt having an infinite carrier for a multiplicity of transverse elements (10) which are accommodated such that they can move freely along the carrier, which transverse elements (10), for this purpose, are provided with a recess, an edge of which forms a substantially radially oriented bearing surface (16) for the carrier. Furthermore, the transverse elements (10) are provided with main surfaces (8, 9) oriented transversely with respect to, the longitudinal direction of the carrier, and with contact surfaces (5), which are oriented substantially in the said longitudinal direction, i.e. are directed axially, for contact with the pairs of sheaves (1, 2), known as the flanks (5). In this case, at least one lateral contact surface (5) is provided with a recess (70), the largest dimension of which is oriented substantially radially and which therefore forms a radially running channel in the lateral contact surface (5), which is at least suitable for radially discharging and/or supplying a lubricant and/or coolant when the transverse element (10) is accommodated between the sheaves of a pair of sheaves.

摘要： The present invention concerns a method for blanking a transverse segment (1) from a basic material (50) that is preformed with two flat parts (51, 52) of constant, but mutually different thickness, whereof a thicker part (51) corresponds with a radially outermost part of the transverse segment (8) and whereof the thinner part (52) corresponds with a radially innermost part of the transverse segment (8). In the blanking method according to the invention, a counter punch (40) is applied with an end face (41) that is provided with a protrusion (42), extending in the width direction of the transverse segment (8) and engaging the thinner part (52) of the basic material (50). Before the transverse segment (8) is actually cut from the basic material (50), the protrusion (42) of the counter punch (40) is pressed into the basic material (50), thus forming a depression (100) therein.
