  • Patent number: 11767906
    Abstract: A transmission includes a housing, having lower and upper housing parts and bearing seats. A web is formed on the lower housing part between two bearing seats, which is pressed against a web provided on the upper housing part and between the bearing seats. When the housing parts are separated or pulled apart, a first web of one of the housing parts projects beyond a planar surface, which restricts the other webs thereof, or the webs of one of the housing parts are restricted by a planar separating surface, and except for a first web, the webs of the other housing part are also restricted by the planar separating surface and the first web projects beyond the separating surface when the housing parts are separated from each other. To form the housing, at least one of the housing parts is elastically deformed and/or preloaded.

    Abstract: A scanning unit for scanning light comprises a deflection element with a mirrored surface and a support element. The deflection element is self-supporting, relative to the fixed structure. The scanning unit has one additional support element extending with an offset to the plane defined by the support element. The scanning unit has a controller in order to control an actuator which can resonantly excite a torsion mode of the support element and of the additional support element. Preferably, the support element and the deflection element are integrally formed and the support element and the further support element are not integrally formed. Preferably, both the support element and the further support element are designed as rod-type torsion springs. Preferably, the support element and the further support element are interconnected by bonding at their respective contact surfaces in an end region facing the fixed structure. The invention further relates to a method for producing a scanning unit.
