Strain wave gear mechanism with an inner seal

A strain wave gear mechanism, comprising:

• a gear mechanism component (CS) having a first internal or external toothing system;
• an elastically deformable transmission component (FS) having a second internal or external toothing system that engages with the first internal or external toothing system;
• a drive component (WG);
• wherein the elastically deformable transmission component (FS) is at least partially in alignment with the gear mechanism component (CS) in the radial direction and is configured to be deformed elliptically by way of the drive component (WG) which interacts with the elastically deformable transmission component (FS) in such a way that the first and second internal or external toothing systems are brought into engagement in opposite regions of an elliptical axis in order to rotate the transmission component (FS) and the gear mechanism component (CS) relative to one another;
• a pivot bearing by which the transmission component (FS) and the gear mechanism component (CS) can be rotated relative to one another, said pivot bearing having a bearing intermediate space;
• and
• an inner seal consisting essentially of an elastomer and formed as a dynamic seal with respect to the bearing intermediate space of the pivot bearing, wherein said inner seal seals an interior space of the strain wave gear mechanism, which interior space is enclosed at least partially by the transmission component (FS) and the first and second internal or external toothing systems and adjoins the pivot bearing.
