The Delta Planetary Gearbox is made using high-tech design software, high-precision gear hobbing machines and comprehensive quality control to ensure that it provides highly accurate gear engagement, smooth running and minimum noise.

Delta Planetary Gearbox PS High Precision Series PA Precision Series
Planetary Gearbox PS High Precision Series The Planetary Gearbox PS Series features many benefits such as low noise, high output torque and low backlash. It is able to smoothly transfer power from motor to applications and to apply to a variety of industries, including aerospace, semi-conductors, machine tools, industrial robots, medical inspection devices, high-precision testing equipment and other automated industry fields. Helical Gear Design The PS Series employs helical gears that provide higher gear mesh frequency than regular spur gears and features smooth performance, low noise, high torque output and low backlash. Synthetic Lubrication The Protective class IP65 sealed design avoids leakage problems and requires no maintenance during the product's lifetime.

Integrated Planetary Arm Bracket and Dual-cantilever Design The planetary arm bracket and the output shaft are constructed in one piece to increase torsional rigidity and accuracy. The entire structure is one-time machined for high controlling accuracy in a specified tolerance.

One-piece Gearbox with Advanced Surface Treatment The gearbox and internal gear ring are constructed in one piece and certified with the DIN6 class standard. The surface of the gearbox is processed with anti-corrosive coating to enhance environment resistance and corrosion resistance capabilities.

Full Needle Roller Bearings Design The planetary gear transmission is designed with full needle roller bearings without retainer to increase the contact surface for enhancing structural rigidity and service life.

High Precision Gear Machining The planetary gear and sun gear are made of high quality Ni-Cr-Mo alloy steel (SNCM220). With high-precision machining including cutting, carburizing to hardness of 57-60 HRC and surface-grinding, the gear provides better wear resistance, impact resistance and longer service life than nitridedand gears (Accuracy Class: DIN6).

Collet Locking Mechanism The input-end and the motor are coupled via a collet locking mechanism. With dynamic balance analysis, it ensures the features of stable concentricity, balance and nonbacklash during power transmission at high speed.

 Modular Design of Motor Connection Plate The special modular design of the motor connection plate is made of aluminum alloy and is suitable for all series of Delta servomotors.

PS High Precision Series Features The Delta Planetary Gearbox is made with high-tech design software, high-precision gear hobbing machines and comprehensive quality control to ensure all products provide highly accurate gear engagement, smooth performance and low noise.
