Abstract: A strain wave gear mechanism (1) has a gear mechanism component (CS) and an elastically deformable transmission component (FS) that is at least partially in alignment therewith in the radial direction (29) and can be deformed elliptically by way of a drive component (WG). Internal or external toothing systems (8, 9) on the gear mechanism component (CS) and the transmission component (FS) are brought into engagement in opposite regions of an elliptical axis to rotate the transmission component (FS) and the gear mechanism component (CS) relative to one another. The transmission component (FS) and the gear mechanism component (CS) are mounted such that they can be rotated relative to one another by means of a pivot bearing (30) which has a bearing intermediate space (16).

Abstract: A transmission component set has a bearing ring (1) and a strain wave gear mounted thereon. Said strain wave gear comprises an input or drive component (2), a flexible or resilient transmission component (4) having external teeth (3), and a gear (6) having an internal teeth (5). The transmission component (4) is fitted onto the drive component (2) and thereby is elliptically deformable such that the external teeth (3) of the transmission component (4) engage with the internal teeth (5) of the gear (6) in opposing areas of a major axis of the ellipse, wherein the gear (6) or the transmission component (4), via its bearing surface (7), can be mounted on a bearing surface (9) of the bearing ring (1) by means of rolling elements (8). The gear (6) or the transmission component (4) and the bearing ring (1) are each provided with at least one indentation or receptacle (10, 11).
