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.
Rouvis
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
