(EN) The invention relates to a strain wave gear mechanism (1) with a gear mechanism component (CS) and an elastically deformable transmission component (FS) which is at least partially in alignment therewith in the radial direction (29) and can be deformed elliptically by way of a drive component (WG) which interacts therewith, in such a way that internal or external toothing systems (8, 9) which areprovided on the gear mechanism component (CS) and the transmission component (FS) can be 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, wherein 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). In order that the risk of a lubricant leak and/or premature dry running of the gear mechanism can be reducedreliably, there is a strain wave gear mechanism, in the case of which an interior space (28) of the strain wave gear mechanism (1), which interior space (28) is enclosed at least partially by the transmission component (FS) and the internal or external toothing system (8, 9) and adjoins the pivot bearing (30), is sealed by means of an inner seal (12) with respect to the bearing intermediate space(16) of the pivot bearing.
(ZH) 本发明涉及一种应力波齿轮机构(1)，具有齿轮机构构件(CS)和与该齿轮机构构件在径向方向(29)上至少部分重叠的、能弹性变形的传递构件(FS)，该传递构件通过与该传递构件共同作用的驱动构件(WG)能够这样椭圆形地变形，使得设置在所述齿轮机构构件(CS)和所述传递构件(FS)上的内齿部或外齿部(8、9)能够在椭圆轴线的相对置的区域中啮合，以便使所述传递构件(FS)和所述齿轮机构构件(CS)相对彼此扭转，其中，所述传递构件(FS)和所述齿轮机构构件(CS)借助于具有轴承中间空间(16)的旋转轴承(30)能相对彼此旋转地受支承，其特征在于，所述应力波齿轮机构(1)的由所述传递构件(FS)以及所述内齿部或外齿部(8、9)至少部分包围的并且邻接于所述旋转轴承(30)的内部空间(28)借助于内密封件(12)相对于所述旋转轴承(30)的所述轴承中间空间(16)密封。
