10:1 Ratio NEMA34 High Precision Planetary Transmission Gearbox for Servo Motor

Servo-motor-gear-box

The reducer is generally used for low-speed and high-torque transmission equipment. The motor, internal combustion engine, or other high-speed running power is used to achieve the deceleration by meshing with the large gear on the output shaft through gear with a small number of teeth on the input shaft of the reducer. The reducer will also have several pairs of gears with the same principle to achieve the ideal reduction effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.

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
