Planetary gearbox is a kind of reducer with wide versatility. The inner gear adopts low carbon alloy steel carburizing quenching and grinding or nitriding process. Planetary gearbox has the characteristics of small structure size, large output torque, high speed ratio, high efficiency, safe and reliable performance, etc. The inner gear of the planetary gearbox can be divided into spur gear and helical gear. Customers can choose the right precision reducer according to the needs of the application.
Description:
1.The output shaft is made of large size,large span double bearing design,output shaft and planetary arm bracket as a whole.The input shaft is placed directly on the planet arm bracket to ensure that the reducer has high operating accuracy and maximum torsional rigidity.
2.Shell and the inner ring gear used integrated design,quenching and tempering after the processing of the teeth so that it can achieve high torque,high precision,high wear resistance.Moreover surface nickel-plated anti-rust treatment,so that its corrosion resistance greatly enhanced.
3.The planetary gear transmission employs full needle roller without retainer to increase the contact surface,which greatly upgrades structural rigidity and service life.
4.The gear is made of Japanese imported material.After the metal cutting process,the vacuum carburizing heat treatment to 58-62HRC. And then by the hobbing,Get the best tooth shape,tooth direction,to ensure that the gear of high precision and good impact toughness.
5.Input shaft and sun gear integrated structure,in order to improve the operation accuracy of the reducer.
6.Ring gear processing technology: Using internal gear slotting machine and hobbing machine; the precision of ring gear after processing can reach .GB7.

Planetary reducer characteristic:
1.Quiet operation:helical gears contribute to reduce vibration and noise.
2.High precision:standard backlash is 3 arcmin,ideal for precision control.
3.High rigidity & torque:high rigidity&torque were used integral ball bearings.
4.Adapter-bushing connection:can be attached to any motor all over the world.
5.No grease leakage:perfect dissolution using high viscosity anti-separation grease.
6.Maintenance-free:no need to replace the grease for the life of the unit.can be attached in any position.
