Helical Gear High Precision Planetary Gearboxfor servo motor& stepping motor:
The high-precision planetary gearbox adopts Helical gear design, and is used in various control transmission fields with servo motors, such as precision machine tools, laser cutting equipment, battery processing equipment, etc. It has the advantages of large torsional rigidity and large output torque.

Characteristics:
1.Right angle steering output realized by spiral bevel gear reversing mechanism
2.The installation distance of spiral bevel gear pair can be adjusted, and the working sound is lower
3.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.Double support cage planet carrier structure, high reliability, 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 design, more connection options, keyway can be opened
8.Helical gear transmission, low return clearance and more accurate positioning
9.Size range:140-180
10.Ratio range:3-100
11.Precision range:3-5arcmin (P1);5-8arcmin (P2)
