Essential Technical Parameters

  • Pitch circle: The theoretical circle where gears mesh and transfer motion
  • Diametral pitch: Number of teeth per inch of pitch diameter
  • Module: Metric measurement of tooth size and spacing
  • Pressure angle: Angle determining load distribution and gear strength
  • Addendum & dedendum: Tooth height above and below pitch circle

    • Common pressure angles include 14.5° for smooth, quiet operation and 20° for enhanced tooth strength and higher load capacity, each influencing performance characteristics and noise levels.

Common Spur Gear Manufacturing Process

For spur gears, hobbing is the most common and cost-effective method for external gears in medium to large quantities.
For internal gears or shoulder-limited designs, shaping or broaching is required.
If high accuracy or low noise is required, shaving or grinding will be applied after cutting.

Disc-Type Gear Milling Cutter

Gear Milling

Advantages:

  • Low equipment requirement
  • Fast changeover, suitable for prototypes and samples

Disadvantages:

  • Low accuracy (typically ≤ DIN 9–10)
  • Low efficiency, not suitable for mass production
Gear shaving

Gear Shaving

Advantages:

  • Significantly improves noise performance and meshing quality
  • Lower cost compared to gear grinding

Disadvantages:

  • Only applicable before heat treatment
  • Not suitable for hardened gears
Gear Hobbing

CNC Gear Hobbing

Advantages:

  • Stable accuracy (DIN 6–8)
  • Applicable to nearly 90% of external spur gears

Disadvantages:

  • Not suitable for internal gears
  • Limited for gears with shoulder or step structures
CNC gear shaping

CNC Gear Shaping

Advantages:

  • Suitable for internal gears
  • Capable of cutting gears close to shoulders or steps

Disadvantages:

  • Lower efficiency compared to hobbing
  • Relatively shorter tool life
