Robust, compact cycloidal gears for heavy-duty applications

Heavy loads are often moved by means of hydraulic systems or large planetary gears. However, cycloidal gears are clearly superior in most cases. Their special design principle enables very high reduction ratios with only two to three gear stages, which guarantees precise and reliable positioning within a hundredth of a millimetre in an extremely compact design. Nabtesco knows the specific challenges of heavy-duty applications and implements robust and efficient gear and drive solutions.

Robust cycloidal gears for precise positioning of heavy loads

Cycloidal gears use cams and rollers for power transmission. This design ensures virtually full contact and even distribution of forces within the gearbox, which produces high rigidity. As a result, it is possible to transmit very high torques with maximum precision and smooth operation. The increase in backlash is infinitesimal, even over long periods (hysteresis loss xtagstartz 1 arcmin, purely mechanical backlash 0.10.2 arcmin).
