Abstract
A method is disclosed for setting an angular displacement of a scissors gearwheel configured to mesh with another wheel in a backlash-free transmission stage. The method includes the steps of fixing the two gear rim parts of the gearwheel in a position corresponding to a desired angular displacement, moving the teeth of the gearwheel and the wheel into backlash-free meshed engagement, fixing the relative position between the gearwheel and the wheel, and cancelling the fixing of the two gear rim parts of the gearwheel.

A method for producing a backlash-free transmission stage comprising the setting of an angular displacement of a scissors gearwheel of the backlash-free transmission stage, wherein the gearwheel has a gear rim, which is provided with teeth and which includes a first gear rim part and a second gear rim part arranged coaxially with the first gear rim part, wherein the two gear rim parts can be turned relative to one another about an axis of rotation of the gearwheel, and wherein the gearwheel is fitted with a spring, which is situated between the two gear rim parts and acts in the circumferential direction to preload the two gear rim parts relative to one another, characterized by the following method steps:
- setting a desired angular displacement of the gearwheel by fixing the two gear rim parts relative to one another in a position corresponding to a desired angular displacement;
- bringing the gearwheel, which is mounted so as to be rotatable about the axis of rotation, and a rotatably mounted wheel, which is likewise provided with teeth and with which the gearwheel meshes in the transmission stage, closer together by movement relative to one another in a setting direction normal to the axis of rotation as far as a relative position in which the teeth of the wheel and the teeth of the gearwheel are in backlash-free engagement;
- fixing the relative position of the wheel and of the gearwheel, at least in the setting direction;
- and
- canceling the fixing of the two gear rim parts of the gearwheel.

- setting a desired angular displacement of the gearwheel by fixing the first and second gear rim parts relative to each other in a desired position corresponding to the desired angular displacement;
- providing a rotatably mounted wheel having teeth adapted to mesh with the teeth of the gearwheel in the transmission stage;
- bringing the gearwheel and the wheel closer together by movement in a setting direction normal to the axis of rotation of the gearwheel into a relative position whereat the teeth of the gearwheel and the teeth of the wheel are meshed in backlash-free engagement;
- fixing the relative position of the wheel and the gearwheel;
- and
- cancelling the fixing of the first and second gear rim parts from the desired position.
