The motor can be used in a wide variety of applications by combining it with a reduction gear(speed reduction).
With the precision processing technology cultivated in watchmaking, Orbray provides geared motors equipped with high-precision gear heads that are quiet and have high transmission efficiency.
Gerahead Types
Spur gearhead
- base-plate
- kana (drive sprocket)
- guide
- spur (driven sprocket)
- bearing
- output shaft
- Most popular gearhead
- Gear shaft is aligned in parallel with the output shaft
- No thrust force is generated
- Rotating direction may differ between input shaft and output shaft depending on the stages.
Spur gear: Gear train using spur wheel, relatively simple structured with fewer number of parts, advantage is less mechanical noise.
Planetary gearhead
- base-plate
- planetary gear
- career plate
- internal gear
- bearing
- output shaft
- Large reduction ratio can be achieved
- Considerable torque transmission
- Input shaft (motor shaft) and output shaft (gear shaft) are aligned in one straight line.
- Torque is distributed evenly to each planetary gear, so the gear is relatively strong in durability.
Planetary gear: It is called a planetary gear because it orbits around the sun gear. Due to large number of teeth, it is suited for high torque transfer.
* Gear head is sellable only in combination with motor.
By attaching a reduction gear mechanism on the motor output shaft, it can generate high torque/low speed, which motor alone cannot achieve.
Compact motors usually feature high speed, but this speed can be reduced to requested level by combining with a gear head.
Because torque increases in proportion to gear ratio, high torque can be easily achieved even in a compact motor.
While a gear head can help generate high torque, it may influence durability and characteristics failure depending on its accuracy.
Using the precision processing technology nurtured in diamond processing/watch part processing, Orbray manufactures and delivers low noise, high efficiency precision gear heads.
