Backlash-free planetary gears for servo motor drives: Maximum precision.
ATEK Drive Solutions explains the significant benefits that a backlash-free planetary gear for servo motor drives offers. These range from improved precision and exact positioning to higher efficiency and thus represent optimal solutions for a variety of demanding applications.
What do we understand by a planetary gear and its function in servo motor drives?
A planetary gear, characterized by gears rotating around a central sun gear, is known for transmitting high torques in a small space. Especially in servo motor drives , the compact design and high power density are decisive advantages, particularly in applications with limited installation space, such as in robotics, where precise planetary gears for servo motors are essential.
Why is backlash-free functionality so critical in a planetary gear for servo motor drives?
In high-precision applications like CNC machines that require an accuracy of up to 0.01 mm, even slight gear backlash can lead to significant errors. Therefore, a backlash-free function of less than 1 arcminute in a planetary gear for servo motor drives is absolutely essential to ensure the highest precision and repeatability, as provided, for example, by Spinea HSPG gears. The goal is always to achieve a precision of under one arcminute, which is achieved by a backlash-free planetary gear.
What influence does backlash have on the system dynamics of servo motor drives?
Gear backlash not only affects accuracy but also the control quality of servo motor drives, which can lead to undesirable vibrations and prolonged settling times. A backlash-free planetary gear significantly reduces these negative effects. It allows for higher system dynamics and can shorten cycle times in pick-and-place applications by up to 15%.

What design features ensure backlash-free operation in planetary gears for servo motor drives?
Achieving nearly zero backlash in a backlash-free planetary gear for servo motor drives requires the highest precision in the manufacturing of gears and bearings. Precision grinding is essential here, to achieve tolerances in the micrometer range. Manufacturers like Neugart rely on hardened and precision-ground gears to guarantee a gear backlash of less than 3 arcminutes in their planetary gears for servo motors. Special gears with a servo motor flange also offer optimized interfaces for seamless integration.
