Gearboxes are rotary motion transmission elements that modulate the torque and speed delivered by the motor installed upstream. The gearbox’s function is to multiply the torque net of its efficiency and reduce the input speed according to the reduction ratio. Another critical factor regarding gearboxes suitable for servo applications is the precision (backlash) mechanical stiffness that the gearbox can guarantee. These factors depend on the construction technology and the quality of the selected gearbox. Servotecnica offers a wide range of low backlash axial and right-angle planetary gears, also in combination with brushless and DC micromotors.
