Gear head series guide


Gear head product range: φ12、φ16、φ22
Please choose suitable gear head by calculating following formula.

Basic formula of gear head selection

1. Calculation of speed
i : Reduction Ratio
ηTransfer effciency
(η1:First reduction )
(η2:Second reduction)
2. Calculation of torque
Tout=Tin x i x η
Nin : Input speed
Tout : Output torque
3. Calculation of transfer efficiency

η= η1x η2x... η η
(*Please calculation ηη as 0.9)
