60~120st planetary gear box for servo motor 3:1 ~512:1 ratio gearbox reducer


Technology wins change
1. The high-quality transmission is provided by hardened and refined sun gear and planetary gear. The integrated housing ensures
optimum concentricity and the components are perfectly matched to ensure maximum operational accuracy.

2. The highest torsional rigidity is provided by the integrated planetary boom and the output shaft; the output bearing is
symmetrically distributed to give the output shaft a better tilting rigidity, and the full complement of the planetary gear
increases the take-up area to ensure a smoother linear drive and effectively provide torque. 40%
3. The perfection of the meshing of the spur gear and the integral ring gear ensures low noise while ensuring outstanding dynamic
4. Careful consideration of the design and fully understanding of the customer's working conditions to develop more value-added
5. The addition of an integrated input shaft design improves concentricity and minimizes inertia. The balanced clamping coupling ring
ensures smooth, vibration-free operation at high speeds.

What Is A Servo?

A servo or servo motor, at its simplest, is a self-contained electromechanical device that allows for powerful and precise positioning control. Servo motors usually consist of at least an electric motor, a gearbox, a potentiometer, a small control board, and an output shaft. The servo’s controller board receives control data from an outside motion controller. Depending on the degree of motion required, the servo’s controller board instructs the servo’s motor to rotate a certain amount, which results in a commensurate rotation of the output shaft. When the potentiometer detects that the output shaft has rotated the specified amount, it sends a signal to the controller board, which stops the motor and holds the servo at that.

What Types of Servo Are There?

Servos come in a few different configurations, depending on the type of motor used or on the desired output of motion. Servos that use DC motors tend to be a bit quicker than those that use AC motors. However, servos using AC motors can be a bit more accurate and durable than servos using DC motors. In a positional rotation servo, the output shaft can rotate up to 180 degrees. In a continuous rotation servo, the output shaft can continually rotate in a direction for as long as instructed to do so by the motion controller. Linear servos are built to provide side-to-side or back-to-front motion, vs. rotational motion as seen in other servo types.

What Are the Factors in Choosing A Servo Gearbox?

As compared to other types of gearboxes, those used in servos are fairly unique due to the specific demands placed on them. A servo gearbox needs to deal with high input speeds, have a wide operating range, provide adequate torque for the application, be robust enough to handle continuous and repetitive use, and have low gear backlash. The specific type of gearbox to use depends on the application and space requirements. Common servo gearbox types include:

  • Planetary: for high system rigidity, compactness, and high torque
  • Spiral Bevel: for larger sizes, better versatility, and higher efficiency
  • Hybrid: for applications requiring the best features of both planetary and spiral bevel gearboxes
  • Bevel Helical: for reduced size footprint and space efficiency
