Drive including a transmission driven by an electric motor

A drive, comprising:

• a transmission adapted to be driven by an electric motor, a drive shaft of the transmission including multiple eccentric regions with differing widths in an axial direction, high points of the eccentric regions being offset relative to one another in a circumferential direction, each eccentric region being radially surrounded by a respective cam disk region;
• wherein, corresponding to the different widths of the eccentric regions, rollers with differing widths in the axial direction are accommodated in respective recesses of a cage and arranged with a radial degree of freedom;
• wherein the cage is rotationally fixed to an output shaft of the transmission;
• wherein the output shaft and the cage are rotatably mounted both relative to the cam disk regions and relative to the drive shaft;
• wherein the first housing part is connected to a second housing part;
• wherein the output shaft includes a wedge-shaped and/or V-shaped groove that is uninterrupted and/or fully circumferential in the circumferential direction, in which rolling bodies are accommodated;
• wherein a V-shaped recess is delimited in an axial direction by the first housing part and against the axial direction by the second housing part;
• wherein the rolling bodies are adapted to roll and/or slide on the respective cam disk regions by the respective eccentric regions during operation of the drive;
• wherein the rolling bodies and/or the eccentric regions with differing widths are arranged behind one another in the axial direction to minimize and/or eliminate dynamic imbalance.

A drive, comprising:

• a transmission adapted to be driven by an electric motor and including a drive shaft having a first eccentric region radially surrounded by a first cam disk region;
• wherein first rollers are accommodated in first recesses of a cage and arranged with a radial degree of freedom;
• wherein the drive shaft includes a second eccentric region radially surrounded by a second cam disk region;
• wherein second rollers are accommodated in second recesses of the cage and arranged with a radial degree of freedom;
• wherein the drive shaft includes a third eccentric region is radially surrounded by a third cam disk region;
• wherein third rollers are accommodated in third recesses of the cage and arranged with a radial degree of freedom;
• wherein the cage is rotationally fixed to an output shaft of the transmission;
• wherein the first eccentric region is arranged in an axial direction between the second and the third eccentric region;
• wherein the output shaft and the cage are rotatably mounted both relative to the cam disk regions and relative to the drive shaft;
• wherein the first housing part is connected to a second housing part;
• wherein the output shaft has a wedge-shaped and/or V-shaped groove that is uninterrupted and/or fully circumferential in a circumferential direction, in which rolling bodies are accommodated;
• wherein a V-shaped recess is delimited in the axial direction by the first housing part and against the axial direction by the second housing part;
• and
• wherein the rolling bodies are adapted to roll and/or slide on the respective cam disk region by the respective eccentric region during operation.
