Präzision in Bewegung

The ZF-Servoplan planetary gearset was developed for being directly attached to servomotors. Thanks to different sizes and a basic modular design, it can be used in almost all areas of automation technology. The servo-controlled transmissions together with the servomotor provide a coaxial input and output. By means of a force locking clamp coupling, the servomotor's output shaft is connected to the sun gear of the servo-controlled transmission. This sun gear drives three planetary gears in a planet carrier. They move on a ring gear with internal gearing. As a result of the allocation to three planetary gears, the forces are distributed evenly resulting in a very compact design with high power-to-weight ratio. The servo-controlled transmissions excel through their low-play gearing with ground gear pairs, making them particularly suitable for accurate positioning tasks.

Planetary gearsets for automation technology can be used in many applications. 1 and 2-stage servo drives with ZF-Servoplan transmissions are applied wherever highly dynamic and exact positioning is required.

Target output torques of 25 to 3 000 Nm are possible with different model sizes. Planetary gearsets for servomotors are used for packaging technology, in shaping technology, as well as generally for machines and facilities.

ZF-Servoplan transmissions are working in a highly precise manner, with great dynamics, and guarantee exact and accurate reproducibility. Machinery energy costs are decreasing thanks to the transmissions' high level of efficiency.

Machinery featuring such equipment is operated in a maintenance-free manner and thus secures stable production processes.
