    摘要: A drive pulley having a hub and a pulley rim is provided, which are mounted in one another so as to be rotatable about a rotational axis, with at least two wound wire springs which are arranged in each case between the hub and the pulley rim in such a manner that they are wound around the rotational axis. In each case one end is supported in the direction of rotation with respect to the hub and the other end is supported in the direction of rotation with respect to the pulley rim and which form a non-supported free spring length between the ends, and which are installed in such a manner that they are pretensioned with respect to each other. At least one of the wire springs bears at one end against a bearing region of one of the parts—hub and pulley rim—and then has a radial distance with respect to a curved supporting face on this one of the parts—hub and pulley rim respectively—which distance increases over the circumference and is reduced progressively to zero over the circumference when the parts—hub and pulley rim—are twisted with respect to each other, while the bearing region is extended into the region of the supporting face 45 and the free spring length is shortened.

    摘要: The invention relates to a rotational vibration damper for a crankshaft of a piston engine. The rotational vibration damper comprises a hub which defines an axis of rotation, and a mass member which, via at least one spring element, is coupled to a hub and is able to rotationally vibrate freely relative to the hub. The mass member is annular in shape and is arranged coaxially relative to the hub, wherein the at least one spring element made of steel is provided in the form of a bendable spring.

    摘要: A roller for belt tensioning systems or wrap drives having a hollow hub and a cylindrical running ring. The hollow hub and the running ring are connected to one another by an annular web and wherein, on both sides of the annular web, the hollow hub and the running ring are supported relative to one another by circumferentially distributed radially arranged ribs. The number of ribs on both sides of the annular web can be a prime number. In addition, or in the alternative, the ribs on both sides of the annular web can be arranged so as to be non-centrically circumferentially offset. In addition, or in the alternative, the number of ribs on both sides of the annular web can deviate from one another. In addition, or in the alternative, the rib assembly can be provided with variable pitch angles around the circumference.
