  • Welded component, in particular planet wheel carrier, method for producing the component and apparatus for carrying out the method
    Patent number: 8523731
    Abstract: A welded component comprising two sheet metal components (51, 53) joined by at least one weld seam (55). A first sheet metal component (51) is disk-shaped and a second sheet metal component (53) is pot-shaped, and at least one of the two sheet metal components (51, 53) has a sheet thickness (s). One (51) of the two sheet metal components (51, 53) has a larger sheet thickness (S>s) in an area of the at least one weld seam (55).

  • ARRANGEMENT OF A PIN IN A BORE AND METHOD FOR POSITIONING AND SECURING THE PIN IN THE BORE
    Publication number: 20100313408
    Abstract: An arrangement of a pin (1) in a bore (2) of a disk (3), in particular a planetary pin (1) in a guide disk (3) of a planetary gear carrier. The pin (1) is secured against rotation by being fixed in place with the disk (3). The pin (1) has at least one recess (6) on the front face in which material (3b) of the disk (3) is forced when the pin (1) is secured in place within the disk (3).
