The more advanced second part is recommended for new KIMoS users in development and production. This section forms the basis for the design, optimization and production of spiral bevel gears and prepares for the follow-up course “T2 - KIMoS for beginners”.
1. PROFILE DEFINITIONS
- General Nomenclature
- Contact ratio for bevel gears
- Addendum / Dedendum / Tooth thickness
- Undercut / Profile displacement
2. BASICS OF THE CONTINUOUS INDEXING SYSTEM
- The Epicycloid as tooth length curvature
- Types of cutters for Face Hobbing
3. PROPERTIES OF THE EPICYCLOIDE AS TOOTH LENGTH CURVATURE
- Point of involute (definition / position)
- Features of gear development with small / large tool diameter
4. AXIAL AND RADIAL FORCES AND DISPLACEMENTS
- Calculation of tooth forces
- Examples Spiral bevel gear / Hypoid
- Definition of Horizontal- and Vertical Displacement
- Main directions of displacement under load for DRIVE and COAST
- Determination of Gear Deflections under Load
5. GEASEOFF AND TOOTH TWIST (BIAS)
- Definition of the EaseOff
- Parameters of influence
- Definition and determination of BIAS
6. LENGTHWISE CROWNING METHODS
- Various methods of generating lengthwise crowning
7. INFLUENCE OF TOOL DIAMETER
- Application of relatively small tool diameter
- Application of relatively large tool diameter
- Displacement directions
- Position of contact pattern
8. MACHINE KINEMATICS
