Planetary Gearbox

PAB High Precision Planetary Gearbox

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.

Planetary gearboxes are widely used for materials handing equipment, engineering machinery,metallurgy industry,mining industry,petrochemical industry, construction machinery,textile industry, medical apparatus and instruments, instrument and meter industry,automobile industry,marine industry,weapons industry, aerospace field,and so on.

PAB series is one of the most famous planetary gearboxes of us.  It has been developed specifically for delivering maximum performance at high speeds. Its helical teeth provide homogeneous synchronism and quiet running noise.  PAB planetary gearbox is exact (P0 and P1 backlash), and the backlash can be one arcmin. PAB planetary reduction planet gear is supported by both ends of the full needle roller bearing, enhancing the torsion stiffness. Two taper rollers support the output shaft of the PAB planetary gearbox reducer on both ends to achieve greater bearing capacity.

PAB inline precision planetary gearbox is a direct connection type with a square body, shortening the positioning time of starting and stopping. It is with shaft output. The Self-aligning input flange makes PAB planetary gearbox connect fast with any motor output shaft. PAB precision planetary gearbox can be dimension customized according to different types of motors. With the compact structure, PAB helical gear speed reducer has lower backlash and high precision than similar models. It is with a long service time.

PAB planetary gearbox has an extensive range of speed ratios. It has a single-stage and a dual-stage.

Single stage ratio:3,4,5,6,7,8,9,10 ;

Double stage:12,15,20,25,30,35,40,45,50,60,70,80,90,100.

As one of the most famous high precision planetary gearboxes, the PAB series have the below features

(1) Lowest backlash of 0-3 arcmin.

(2) High torque and high dynamic.

(3) High-cost performance.

(4) Applicable for all servo motor and stepper motor.

(5) Improve the rigidity and increase the motor rotor inertia.

(6) Shorten the positioning time of starting and stopping

(7) Miniaturization of motor power. At the same time, it improves the stability of inertia load and reduces the vibration.

(8) The surface of the gearbox is treated with electroless Nickel, and the connection plate is treated with the blue anode to improve the tolerance and corrosion resistance of the environment.

(9) The structure that the planet carrier and the output share integrated guarantees the maximum torque stiffness and stability.

(10) Electroless Nickel treatment was adopted on the gearbox surface, and blue anodizing treatment was employed on the connection plate to enhance the tolerance and corrosion resistance of the environment.

(11) High efficiency of 95%

(12) Lift-time lubrication.
