Rouvis

Rouvis is a semi-analytical calculation code designed to predict the quasi-static behavior of rack and pinion gears. Rouvis is co-developed with Jtekt Europe and the LaMCoS laboratory of INSA Lyon.

Capabilities

  • ZI or ZK screw profile
  • Wheel cut by a hob
  • Metallic screw (considered to be non-deformable), plastic wheel (viscoelasticity considered)
  • Misalignments
  • The entire tooth flank of the wheel is meshed (7 teeth analyzed)
  • Structural flexibility taken into account by preliminary FE calculations
  • Tooth bending : mixed FE/analytical influence coefficients method
  • Contact deformations: generalised Boussinesq and Cerruti analytical formulations (normal and tangential contact effects are considered)
  • Mirror method to avoid numerical edge effects

  • Non-loaded kinematic error
  • Backlash
  • Slip speeds
  • Loaded transmission error
  • Loaded contact lines
  • Pressure fields
  • PV Almen factors
  • Stiffness
  • Tooth root stress fields
  • Loads export for structural stresses

  • Metal-to-metal contact (bronze wheel)
  • Consideration of screw flexibility
