Product Description

High Precision Nema34 Stepper Motor Helical Planetary Gearbox Reducer

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.

Product Description

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.

Characteristics:

1. The spiral bevel gear reversing mechanism realizes right angle steering output
2. The installation distance of spiral bevel gear pair can be adjusted, and the working sound is lower
3. The grinding bevel gear pair can be selected, and the working sound is more stable and quiet
4. Integrated design, high precision and high rigidity
5. The double support cage planet carrier structure has high reliability and is suitable for high-speed and frequent forward and reverse rotation
6. Compared with the corresponding square fuselage series, it has the same performance and higher cost performance
7. Coupling meter, more connection options, keyway can be opened
8. Helical gear transmission, low return clearance and more accurate positioning
9.Size range:140-180 mm
10.Ratio range:3-100
11.Precision range:3-5arcmin (P1); 5-8arcmin (P2)
