Abstract: A method of manufacturing a composite including a sun gear and a planet carrier for a planetary gear unit, the sun gear and the planet carrier being manufactured as separate components and then joined together. The two components are joined together by establishing, by deformation, a form-fit connection between the two components.

Abstract: The present invention relates to a method of manufacturing a composite comprising a sun gear and a planet carrier for a planetary gear unit, the sun gear and the planet carrier being manufactured as separate components and then joined together. According to the present invention, the two components are joined together by establishing, by means of deforming, a form-fit connection between the two components.

Abstract: A multi-stage gear is provided with a planetary gear and a strain wave gear adjacent to the multi-stage gear, wherein a output of the planetary gear maintains a drive connection with a wave generator of the strain wave gear, and wherein the planetary gear is arranged at least partially radially within the strain wave gear. It is provided that the wave generator is mounted radially on a ring gear of the planetary gear.

Abstract: An electric motor with an add-on unit, such as a gearbox unit, encoder unit or controller unit, and disclosed whereby the electric motor and add-on unit can be firmly connected to each other. For a firm connection, a shrink ring is thermally shrunk on to the electric motor and add-on unit in the area of the joint so that the shrink ring covers the joint. A method is also disclosed for producing the connection, wherein a temperature difference is first created between the shrink ring on the one hand and the electric motor as well as add-on unit on the other hand, whereby furthermore the temperature of the shrink ring is greater than the temperature of the electric motor and add-on unit and whereby the components are then joined together and held so that the shrink ring shrinks on to the electric motor and add-on unit.
