Planetary gear reducers are compact components that strive to maximize the transmission of torque in various applications. The mechanisms ensure the transmission of high torque levels while simultaneously decreasing the required number of motor revolutions for a set level of power. The reducers are composed of a gearbox and aligned input and output shafts. Industrial automation systems, including DC transmission, servo, and stepping systems, use planetary gear reducers to efficiently manage tasks that demand high levels of torque.
Compared to similar gear reducer systems, these components weigh less and have a compact design that can fit in more designs. Planetary gear reducers can maintain the same torque output while decreasing up to 50% in size.
These gear reducers have ball bearings that help the components operate smoothly and efficiently. This reduces wear throughout their operational lifespan, leading to less damage and long product life.
Planetary gear reducers offer higher axial load speeds and radial load speeds than comparable systems. This increases their overall reliability and sturdiness and decreases the potential for misalignment. These features allow planetary gear reducers to mitigate the effects of vibration and ensure consistent transmission over time.
Planetary gear reducers are built for maximum teeth engagement. Because more teeth are in contact, it can both handle more torque and transfer more torque.
Each stage of a planetary gear reducer system can be stacked or modified for custom configurations that meet the needs of a given application. Planetary gear reducers are also easy to work with: once they're installed in a cylindrical gearbox, the gear reducers can be installed almost anywhere.
