Apex Dynamics, Inc. is a worldwide leader in manufacturing of planetary gearboxes. They are continuously improving processes, finding proper and effective methods to provide customers new solutions for difficult applications, and developing new products.

The APEX servo gearbox has been designed for direct attachment to popular servomotors. The power is transmitted from the motor to sun gear. The sun gear drives three planet gears, which are contained within an internal toothed ring gear. The planet gears are mounted on the planet carrier with double wall supports. The planet carrier is part of the output shaft. So when the sun gear rotates, it drives the three planet gears inside the ring gear. As planet gears rotate, the carrier turns, and automatically the output shaft rotates. Due to the load sharing into multiple tooth contacts, the planetary gearbox provides the highest torque and stiffness for a given envelope. The other significant advantages are simple and efficient lubrication and a balanced system for high speeds. The balanced planetary kinematics and the associated load sharing make the planetary gearbox truly ideal for servo applications.
