Objectives:

Upon completion of the training, the attendants will be able to carry out the following:

  • Consult a definition plan, a range of manufacture, a report of and extracting the useful elements;
  • Understand and follow the whole process of making a gear, design at the reception;
  • Identify the theoretical and practical elements that are essential for producing quality gears and guarantee their service life.

18th – 19th July 2023

Time:

09:00–17:00 (GMT+8)

Who should attend?

Technicians in the methods, control, quality and manufacturing departments, but also all those (project managers, sales engineers, buyers and who want to know about gears and their implementation work.

PRE - REQUISITES

None

PEDAGOGICAL MEANS

Teaching method alternating theory and practice through case studies or works directed.

Course outline:

  • Basic concepts on the geometry of gears to “Teeth in involute”
    • Spur and helical gears;
    • Meshing (driving report, interference, slip);
    • Tooth corrections (profile and helix corrections);
    • Resistance to contact pressure and breakage, service life.
  • The principles of manufacture of cylindrical gears (for each machining process, presentation of machines and tools):
    • Gear cutting processes (hob, pinion);
    • Finishing processes of teeth (grinding, shaving, honing);
    • Other machining processes.
  • Principles of tolerance and control of cylindrical gears:
    • Control of teeth in manufacture;
    • Metrological control of the teeth;
    • Case study: reading of plans and exploitation of measurements.
  • Concepts on the implementation of cylindrical gears:
    • Operating clearance;
    • Lubrication and evacuation of calories;
    • Behaviour and the degradation of the teeth in use;
    • Notions of maintenance linked to the monitoring of gearboxes (noise, vibrations
    • Examples of gear assemblies (gearboxes with parallel trains, planetary transmissions …).
  • Presentation of other types of gears.
