MAB Series Planetary Gearbox

Description of MAB High Precision Planetary Gearboxes

MB Series is a kind of super high precision and super high efficient planetary gearbox, with double support output, long span, high stability, wide surface of the sun gear and planetary gear, larger related technical parameters to accomplish high-intensity work. All gears inside the MKD servo planetary gearbox are helical design, high bite rate, smooth continuous operation, low noise, low backlash. Integrated design of inner ring and shell, high precision, high wear resistance. Integrated connection board design makes it perfectly matches with all kinds of servo motors, and stepper motors perfectly. The lowest backlash, as high as 95% efficiency and lifetime lubrication, makes the MKD helical gearbox the best choice for customers.

MKD MB series planetary gearbox for servo motor is a good alternative gearbox to AB series of APEX gearbox. We have many customers who before used Apex planetary gearbox or spiral bevel gearbox now choose our MB gearbox or our right angle gearbox AT series in the category of the 90-degree gearbox.

Planetary gearbox models of Apex Dynamics: AB042 / AB060 / AB060A / AB090 / AB090A / AB115 / AB115A / AB142 / AB142A / AB180 / AB220

Planetary gearbox models of MKD Industrial: MAB042 / MAB060 /MAB060A / MAB090 / MAB115 / MAB142 / MAB180 / MAB220

Besides replacing the Apex gearhead, MKD MAB series servo motor gearboxes also can replace sesame gearbox, Shimpo planetary gearbox, Neugart gear head, Liming gearbox, Kofon planetary gearbox, alpha planetary gearbox, pht planetary gearbox, etc. Please send us the gearbox drawing or offer us the models or drawing of your servo motor and stepper motor, we shall help you select an equivalent planetary gearbox for you. If any technical questions, welcome to consult our sales engineer for free, we will try our best to support you all-round. As for the planetary gearbox price, we will offer you our better price than the above brand to reduce your spare part’s cost to increase the competitive power of your project or machine sales.

Overview of Specifications

Inner Structure of MAB Precision Servo Gearbox

Features of MAB Series Planetary Servo Gear Reducer

The overall design allows the servo motor to input at high speed and achieve maximum torque output. Precision gear design and processing have characteristics of low operating backlash, high efficiency, low noise, and long life. The motor power is miniaturized, improving the stability of inertial load and reducing vibration.

Installation Steps of Precision Planetary Gearbox

Step One:  wipe off the anti-rusting additive and grease on the motor shaft.

Step Two: Remove the rubber plug.

Step Three: Rotate the input shaft to align the fastening bolt with the plug hole. Please make sure that the cap screw is loosened. If there is a shaft sleeve attached, please install it according to the figure below.

Step Four: Place the reducer vertically in a flat place so that the motor mounting face of the planetary gearbox is upward. Insert the motor shaft into the input shaft slowly to avoid hitting the input shaft. Please make sure that the flange of the motor is close to the flange of the servo gearbox. Tighten the motor mounting bolts based on the designated tightening torque (please refer to table 1)

Step Five: Use a torque wrench to tighten the clamping bolt according to the designated fastening torque（ Refer to table 1)

Step Six: Install the rubber bolt. The whole installation procedure is finished.

Inner Construction Configuration of MB Planetary Gear Head

The lubrication structure of the MKD planetary gearbox is mainly applied to the inner screw gear structure to ensure high-efficient output. On one hand, it could reduce the axial thrust generated by the running of the planetary gears. On the other hand, it could increase lubrication, and reduce friction and noise.

1. High precision integrated corner block system

2. The wider gear surface and larger parameters make the high strength of the planetary gearbox realized.

3. All gears inside the MKD servo planetary gearbox are helical design, high bite rate, smooth continuous operation, low noise, low backlash.

4.Integrated design of inner ring and shell, high precision, high wear resistance.

5. Integrated connection board design makes it perfectly matches with all kinds of servo motors, and stepper motors perfectly.
