Acoustic waves, indeed, are generated by most planetary gearboxes having straight teeth because the "contact ratio" of the internal gears (number of teeth in contact) is generally below 2.0 in spur gear stages, and 2.0 is the limit after which a gear stage becomes quiet because 2 teeth are always in contact.
Thanks to the helix angle allowing more teeth to be contact at the same time, the contact ratio is generally higher than 2 in helical gearboxes, so they can be more silent.
On the other hand, helical gears generate high axial efforts to the internal components of the gearbox such as bearings or friction disks, so such construction can be prejudicial to a planetary gearbox life if some rules are not respected. The more helix angle, the more efforts on the bearings!
Thanks to the PerfectPitchTM concept, Reckon low-backlash planetary gearboxes are quiet, reliable and calculated for a long lifetime in tough working conditions.
