Grob, Inc.

Compared to straight-sided (i.e., parallel) splines, involutes splines offer several advantages, including:

  • Simpler design, which allows for easier—and thereby cheaper—manufacturing operations
  • Greater contact area along the tooth profile, resulting in smoother operation
  • Higher tolerance for misalignment
