Definitions

  • the invention can be applied as soon as the movement of mounting imposes a higher clearance, even very slightly, the only set of manufacturing tolerances.
  • the wedging angle is very small, of the order of 5 °
  • the E / e ratio may be less than 1.3, but the mounting movement must still be helical, ie of the type mentioned above.
