Timing Belt Pitch 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
- High Speed
- Vibration
- Noise
- Registration
- Linear Positioning
- High Speed
- Registration
- Power Transmission
- High Torque
- High Speed
- Anti-Racheting
