A sintered member having an annular shape, includes: a first face facing one side in an axial direction; a second face facing the other side in the axial direction; an inner peripheral face connected to an inner peripheral edge of the first face; and a plurality of tooth groups and a plurality of tooth-missing parts which are alternately disposed along a circumferential direction of the inner peripheral face. The second face includes a plurality of ball grooves arranged in parallel in the circumferential direction. Each tooth group includes a plurality of spline teeth that are continuous in the circumferential direction of the peripheral face. The number of plurality of tooth-missing parts is the same as the plurality of ball grooves. Positions in a radial direction in which the plurality of tooth-missing parts are formed are within ranges in the radial direction in which the ball grooves are formed.

According to examples, a processor may dilate a first digital model of a first 3D part a predefined amount and a second digital model of a second 3D part the predefined amount, in which the first 3D part and the second 3D part are to be fabricated together in an assembly to have a functional relationship with respect to each other, and in which the first digital model and the second digital model are spaced from each other in a manner that corresponds to a spacing of the first 3D part and the second 3D part in the assembly. The processor may determine a spatial relationship between the dilated first digital model and the dilated second digital model and may determine, based on the determined spatial relationship, whether the assembly of the first 3D part and the second 3D part is predicted to function properly when the assembly is fabricated.

A vehicle having an internal combustion engine mounted in the vehicle such that a crankshaft of the internal combustion engine runs in a longitudinal direction of the vehicle is provided with a flexible drive is provided that comprises a wheel, in particular a pulley, which is arranged such as to rotate about a longitudinal axis of the vehicle and which is arranged in front of the internal combustion engine when viewed in the direction of travel of the vehicle. The wheel has at least one weakened section which allows or facilitates a compression of the wheel in the longitudinal direction of the vehicle upon a head-on collision. In addition, the wheel may be arranged to cooperate with a recess in the front of the engine to permit further displacement of the wheel toward the engine during a collision.
