LOW BACKLASH PLANETARY GEARBOXES

you make every second count

*Reckon offers 1 arc-min backlash from size 40 mm to size 285 mm RECKON8 Innovation needs performance

Acoustic waves are emitted by most geared systems having their contact ratio (number of teeth being in contact at the same time in a gearbox) below 2 - like most spur geared systems. Using helical gears allows increasing the contact ratio above 2 to offer quiet operation.

That is why all Reckon® gearboxes only use helical gears.

Helical gears are recognized for their silent operation, but on the other hand they generate strong axial efforts to the internal elements of the gearbox (such as friction disks, planet carriers or bearings) so using them unconsciously can be prejudicial to a planetary gearbox life.

PerfectPitch™ The PerfectPitch™ concept is a combination of features that we believe are necessary to provide silent, reliable planetary gearboxes. • Reckon® gearboxes all use the smallest helix angle possible, in order to provide a silent operation while limiting axial efforts to the minimum. • We only use carburized and quenched satellite gears, as we considered they allow the toughest operating conditions (sharp acceleration, emergency stops, fast reversals...). • Every gearbox noise level is tested in our quiet room, at up to 6,000 rpm before shipment. • All gear calculations were based...

Innovation needs performance How do planetary gearboxes work? The sun gear (1) rotates together with your motor shaft. It meshes simultaneously with 3 or more satellite gears (2) Satellite gears rotate simultaneously around the sun gear and inside the ring gear (3) > The reduction ratio between the sun gear and the satellite gears is: Satellite gears' number of teeth (Z2) / Sun gear's number of teeth (Z1) > The reduction ratio between the satellite gears and the ring gear is : Ring gear's number of teeth (Z3) / satellite gears number of teeth (Z2) The satellite gears rotate inside the ring...
