1. Application and Classification of Bevel Gears

  • Application of spiral bevel gears
  • Types of axle design
  • Characteristics of classification

2. Gear Cutting Systems

  • The generating rack
  • The generating plane gear
  • Generated cutting systems
  • FORM cutting systems
  • Description /definition of Neutral Data
  • Cutting systems (single indexing: single flank / completing; continuous indexing)

          3. Gear geometry / - Dimensions

          • General dimensions
          • Line of contact / Pressure angle
          • Contact ratio
          • Path of contact
          • Addendum / Dedendum / Tooth thickness
          • Backlash
          • Profile displacement

          5. Comparison Single Indexing / Continuous Indexing

          • Indexing Systems
          • Creating length crowning

          • Generating plane gears
          • Generating cutting lines
          • Blade systems
          • Displacement characteristics

          6. Basics of the Continuous Indexing System

          • The Epicycloide as tooth length curvature
          • Types of cutters for F.H.

          7. Particularities of the Epicycloide as Tooth Length Curvature

          • Point of Involute
          • Features of gear development with small / large tool diameter

          8. Face Hobbing: Generating- and FORM cutting system

          • Length crowing with tilt of tool
          • The generating system
          • The FORM system

          9. The EaseOff

          • Definition of the EaseOff
          • Parameters of influence

          10. Tooth Twist / BIAS

          • Components of gear displacement
          • V/H - check
          • Definition of BIAS
          • Effects of BIAS
          • Modification of BIAS (Modified roll / Helical Roll)

          11. Axial and Radial Thrust of Spiral Bevel Gears

          • Calculation of forces
          • Example Spiral Bevel Gear
          • Examples Hypoid
          • Main directions of displacement under load for DRIVE and COAST

          12. Influence of Tool Diameter

          • Application of relatively small tool diameter
          • Displacement of tooth contact in comparison F.H and F.M.
          • Application of relatively large tool diameter
          • Displacement of tooth contact in comparison F.H and F.M.
