Gearbox Recommended Resonance Frequency
Gearbox Recommended Resonance Frequency |
|
Some gearboxes such as type "Wave Strain Gear" are sensitive to resonance frequency. Below is a table of recommended minimum resonance frequencies based on application type.
The are several ways to work around the minimum resonance frequency including stiffening the mechanism, changing the gearbox ratio and/or size, or adjusting the motion profile to "move through" the resonance speed window as quickly as possible. When in doubt, contact the gearbox vendor.
