Definitions

  • the guide slots 7, 8 form a housing side Part of the in the Fig. 1 and 2
  • the ribs 28, 29 are arranged orthogonal to each other, therefore indicated by double arrows 11, 12 indicated width directions of the guide slots 7, 8 at an angle and here at a right angle to each other.
  • the guide slots 7, 8 extend as well as the longitudinal axis of the guide pin 15 parallel to the axis of rotation 2 of the countershaft 3 (FIGS. Fig. 1 . 2 ).
  • the locking plate 5 has two compared to its base body with the teeth 20 at right angles bent leg.
  • the bent legs are orthogonal to each other and to the base body and form sliding surfaces 9, 10.
  • Perpendicular to the surface of the sliding surfaces 9, 10 standing surface normal are indicated by arrows 13, 14.
  • the sliding surfaces 9, 10 are inserted into the respective associated guide slots 7, 8, wherein the surface normal parallel to the in Fig. 3 shown width directions of the associated guide slots 7, 8 are.
  • the surface normals are parallel to the surface of the associated ribs 28, 29 (FIG. Fig. 3 ).
  • the sliding surfaces 9, 10 are in the guide slots 7, 8 parallel to the axis of rotation 2 ( Fig. 1 ) guided in a sliding manner.
