Definitions

  • the housing element 2 is rotatably coupled to a flexible gear element 8, which is designed as a collar sleeve.
  • the flange, that is to say the collar, of the flexible gear element 8 is designated by 9.
  • the collar 9 merges at its inner edge into a cylindrical section 10, which has an external toothing 11 see is.
  • the external toothing 11 partially engages in a manner known per se in an internal toothing 12 which is formed directly by the output element 4.
  • the roller bearing 14 has an outer ring 18.
  • the outer ring 18 is a resilient component.
  • the rolling elements 16 permanently force the outer ring 18 into a non-circular shape corresponding to the shape of the inner ring 15.
  • the area of the cylindrical section 10 provided with the external toothing 11 directly surrounds the outer ring 18 without being firmly connected to it.
  • the toothings 11, 12 are brought into engagement with one another only at two points, namely in the region of the major axis of the inner ring 15.
  • the inner sleeve-shaped section 21 merges into a flange section 22, which is located in front of the collar 9.
