摘要： An unbalanced shaft (1a, 1b, 1c), particularly for compensating mass forces and/or mass moments of inertia of an internal combustion engine (2) is provided. The shaft includes a shaft section (10, 11, 12) and a bearing journal (13a, 13b, 13c) axially adjacent to the shaft section, the bearing journal includes a fully cylindrical outer peripheral surface (18) serving as an inner raceway for the rolling elements (16) of a rolling bearing (14) and the bearing journal has a multi-piece configuration, so that both the shaft section and the bearing journal possess a mass center of gravity that, for producing the shaft unbalance, extends eccentric to the axis of rotation (19) of the unbalanced shaft. For supplying lubricant to the inner raceway and the rolling elements, an oil channel (20a, 20b, 20c) extends radially outwards through the bearing journal and opens, relative to the mass center of gravity of the bearing journal, on the other side, situated beyond the axis of rotation, on the outer peripheral surface.

摘要： A mass balancing mechanism of an internal combustion engine, in which the mechanism includes a compensation shaft (1, 1′) formed as a tubular carrier shaft (5, 5′) having a mounting point (10, 10′) for the radial mounting of the compensation shaft. The mechanism further includes an unbalanced mass (6) joined to the carrier shaft. A needle roller bearing (2) is used for a radial rolling bearing-mounting of the compensation shaft, with the needle rollers (11) of the needle roller bearing being in rolling contact with the mounting point which is configured as an inner raceway and possesses a width which is variable in peripheral direction, so that, in a region situated diametrically opposite a load zone in whose peripheral region the inner raceway is loaded by the radial load of the unbalanced mass which rotates together with the compensation shaft, a width (14) of the inner raceway is smaller than the length of the needle rollers and tapers clearly or is interrupted in peripheral direction. The tapering or interruption of the inner raceway is produced by one or more trough-shaped depressions (15, 15′) formed locally in the carrier shaft.

摘要： Axial thrust washers are provided in the axial contact region of the bearing raceway of an unbalance shaft. The axial thrust washers do not extend beyond 360° in the circumferential direction, but extend only over a little more than the unbalance masses which extend in this region. The end sections of the axial thrust washers are bent over so that they are supported on the prominent unbalance masses, and form a funnel-like entry region for the rolling elements or for a cage of the rolling bearing which houses the rolling elements.

摘要： The invention relates to a method for the installation of an assembly, in particular of a balance shaft unit for the compensation of mass or torque for internal combustion engines in motor vehicles. The assembly includes a housing part having at least one bearing section, at least one rotating component and at least one rolling element bearing for the axially fixed journaling of the rotating component in the bearing section of the housing part. The bearing section is closed in the peripheral direction and is made in one piece. The rolling element bearing has a first ring section and a second ring section, with the first ring section being associated with the rotating component and the second ring section being associated with the bearing section of the housing part. The rolling element bearing is axially fixedly installed at the rotating component or in the bearing section of the housing part in a first installation step. The rotating component is cooled and/or the housing part is heated in a second installation step. The rotating component is introduced into the bearing section of the housing part and is held there in a third installation step until a temperature compensation has taken place between the rotating component and the housing part such that a shrink-fit connection is established between the rotating component and the first ring section or between the second ring section and the bearing section of the housing part.
