Abstract:
An apparatus (1) having a drive shaft (18) with an end and a shaft diameter, and having a disc-shaped support (17) which is rotationally locked to the drive shaft (18), for carrying at least one component part, which support (17) has a hub portion (19) and two tubular projections (22,23) which are coaxial with the drive shaft (18) and which project from the hub portion (19) in opposite axial directions (22,21), and which support (17) is force-coupled to the drive shaft (18) with the aid of the two projections (22,23), characterized in that an annular connecting zone (24,25) has been provided in the interior of each of the two projections (22,23), which annular connecting zone has a given dimension (H1,H2) in the axial direction and has a given inner diameter (D1,D2), and each of the two projections (22,23) is connected to the drive shaft (18) by a press-fit in the area of its annular connecting zone (24,25), and the two inner diameters (D1,D2) of the two annular connecting zones (24,25) have different values that are less than said shaft diameter, and diameter (D1) being adjacent said end and being smaller than diameter (D2).
