Timing Belt Tooth Profile Comparison

Timing belt tooth profiles can be categorized into the following timing belt group summaries:

Trapezoidal Timing Belt Tooth Profiles

  • MXL
  • XL
  • L
  • H
  • XH
  • XXH
  • T
  • AT

Curvilinear Timing Belt Tooth Profiles

  • HTD

Modified Curvilinear Timing Belt Tooth Profiles

  • PowerGrip GT2
  • PolyChain GT
  • STD
  • CTD

The desired characteristics of the timing belt tooth profile can be broken down into the following:

  • High Torque
  • High Speed
  • Anti-Ratcheting
  • Vibration
  • Noise
  • Registration (Positioning Accuracy)

These desired timing belt tooth profile characteristics are what a designer should look at in terms of the timing belt application they are designing for.

Timing belt applications can be summarized into the following.

  • Conveying
  • Linear Positioning
  • Power Transmission
  • Other

The characteristics of the timing belt tooth profile can then be further assigned to a specific timing belt application.

  Conveying Linear Positioning Power Transmission Other
