Abstract
A method for connecting a first component to a second component to form an assembly forms a press fit connection between the first component and the second component, for which purpose the second component is produced having an annular component section. A recess is formed, in which the first component is at least partially arranged. At least the annular component section of the second component is produced as a sintered component and has net shape or near net shape quality at least in the region of the recess.
Claims6
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.
