Product Description

PXR120 series helical gear low backlash transmission planetary gearbox for CNC machine

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 Parameters

Characteristics:

1.Low Noise:The use of helical gear design,to achieve a smooth,quite operation of the reducer.
2.High Precision:Backlash is 3 arcmin or less,accurate positioning.
3.High Rigidity,High Torque:The output shaft used large size,large span double support bearing design,which improves the rigidity and torque of the reducer.
4.High Efficiency:1-stage up to 95% or more,2-stage up to 92% or more.
5.Maintenance-Free:Low grease wear,can be lifetime lubrication.
6.Sealing Effect is Good:Lubricating grease with high viscosity,not easy to separate the characteristics,ip65 protection class to ensure that no grease leakage.
7.Installation Unrestrained:Can be installed arbitrarily.
8.Wide Applicability:Applicable to any type of servo motor.
9.An organic [integral] whole output axis.
10.Speed ratio range:3-100.
11.Precision range:3-5arcmin(P1 level);5-8arcmin(P2 level).
12.Size range:60-140mm.
