Lowest Noise, compared with conventional speed reducer

10% less noise with Helical gear, compared with conventional Spur gear units. (SHIMPO research)
By adopting helical gears, benefi t from low speed fl uctuation and smooth rotation. Useful for chemical feeding and medical pumps

Operating principles

Primary stage reduction　Motor - Input Gear - Planetary Gear A - Carrier

Operation principle from Servo motor to Carrier is as follows:

1. Servo motor rotation is transmitted to the Input gear, which is installed on the M shaft.
2. Input Gear provides the revolution to the Planetary gear A, which is engaged with Internal gear A.
3. Planetary gear's revolution makes the Sun gear rotate at the Final stage through the Carrier. Principle of operation Rotational direction is the same as Input direction.

Final stage Reduction　　Carrier - Sun Gear - Planetary Gear B - Output Shaf

Operation principle from Carrier to Output shaft is as follows:

1. Carrier's rotation is transmitted to the Sun gear, which is installed on Carrier.
2. Sun gear gives the revolution to Planetary gear B, which is engaged with Internal gear B.
3. Planetary gear's revolution provides Output shaft rotation. Rotational direction is the same as Input direction.
