1. A method for connecting a first component to a second component to form an assembly, comprising:
producing the first component as a shaft;
defining a diameter of a base circle of an external toothing;
shifting the diameter of the base circle of the external toothing by 55% to 90% of an average overlap in a direction of a gear center to form a shifted diameter of the base circle;
creating a pressing mold for producing a sintered gear with the shifted diameter of the base circle;
producing the second component as the sintered gear having an annular component section in which a recess is formed and for which the external toothing is formed on an outer lateral surface of the annular component section;
forming a press fit connection between the first component and the second component, wherein the first component is at least partially arranged in the recess;
wherein at least the annular component section of the second component has net shape or near net shape quality at least in a region of the recess;
wherein the base circle is a circle having a diameter at which tooth flanks of two contacting gears do not touch and no transmission of force takes place, and
wherein the average overlap is determined by the formula:
dw-d
where dw is a diameter of the shaft and d is an inner diameter of the second component.
