Skills

Numerical tools, based on research work, model the quasi-static and dynamic behaviour under load of mechanical transmissions and their components (gears, bearings, splines). The data, the calculation methods and the results can be adapted to the industrial needs.

Mechanical design

 

Calculation methods

  • Quasi-static behaviour under load (More…)
  • Dynamic behaviour
  • Design optimization

 

Fields of studies

  • Mechanics of contact
  • Failure
  • Wear
  • Noise and vibration (NVH)

 

Cylindrical

Definition of spur and helical gears

Optimization of tooth modifications (profile, crowning, …)

Models for metal or plastic gears

Spiral bevel

Three types of geometry can be generated:

  • Analytical
  • Simplified Gleason type
  • Tooth defined by importing point files (topography …)

Optimization of tooth modifications

Models for metal gears

Worm gear

Two models for:

  • Metal screw and plastic wheel
  • Metal screw and bronze wheel (ability to simulate the wear)

Pinion / rack

Two types of rack geometry:

  • Constant pitch
  • Variable pitch

Models for metal gears

Faces

Flat or conical face gear

Spur or helical cylindrical gear

Model for metal gears

Splines

Involute splines

Tooth modifications

Manufacturing defaults

Model for metal splines

Bearings

Ball bearings with 2, 3 et 4 points of contact

Roller bearings

High rotation speed : models with friction at contacts
