Gear mechanism having a gear stage and including a sun gear, planet gears and a crown-toothed gear

A gear mechanism having a gear stage, comprising:

• an input shaft;
• a first planet carrier;
• a first gear;
• a second gear;
• an output shaft;
• and
• a housing;
• wherein the input shaft is oriented coaxially to the output shaft;
• wherein the input shaft has a first crown toothing on an end face facing the output shaft;
• wherein the output shaft has a second crown toothing on an end face facing the input shaft;
• wherein the first crown toothing is at a distance from the second crown toothing;
• wherein a toothing of the first gear meshes with the first crown toothing;
• wherein a toothing of the second gear meshes with the second crown toothing;
• wherein the first gear is connected to the second gear for conjoint rotation;
• wherein the first gear is arranged at a distance from the second gear;
• wherein an axis of rotation of the first gear is arranged at a distance from an axis of rotation of the input shaft in a radial direction relative to the axis of rotation of the input shaft;
• wherein a direction of the axis of rotation of the first gear has an angle between 0° and 90° to a direction of the axis of rotation of the input shaft;
• and
• wherein the first gear and the second gear are rotationally mounted by bearings received in the first planet carrier, the first planet carrier being connected to the housing of the gear mechanism in a fixed manner and/or for conjoint rotation.

A gear mechanism having a gear stage, comprising:

• an input shaft;
• a sun gear;
• a first planet carrier;
• a first and a second planet gear;
• a first crown-toothed gear;
• an output shaft;
• and
• a housing;
• wherein the input shaft is oriented coaxially to the output shaft;
• wherein the output shaft is arranged as a hollow shaft and the input shaft projects through the output shaft;
• wherein axes of rotation of the first planet gear and the second planet gear are arranged coaxially to each other and/or have an angle of between 10° and 80° to an axis of rotation of the input shaft,
• wherein the first planet gear is connected to the second planet gear for conjoint rotation;
• wherein the first crown-toothed gear is connected to the housing for conjoint rotation;
• wherein the sun gear is connected to the input shaft for conjoint rotation;
• wherein a toothing of the first planet gear meshes with a toothing of the first crown-toothed gear and with a toothing of the sun gear;
• and
• wherein a toothing of the second planet gear meshes with a crown toothing formed on the output shaft.
