Worm Gearboxes

The Covera wormgearbox series is designed especially for non-continuous operation. Thanks to its Concave – Convex tooth profile it can take higher peakloads than conventional profiled wormgears. The reason Covera tooth profile is stronger than a conventional worm tooth profile is that the surface pressure is spread on large area causing a significant surface pressure reduction. The noice level is substantially lower than vertical or bevelgears.

The ratio scale from 5:1 to 3550:1 gives ta wide selection of exact ratio needs. Whether you needed a worm gearbox to jacking systems, bark removal processes, mixer or, for example, a feeder, you can find a suitable Covera gearbox from our product portfolio. Covera gearboxes are made to meet even the roughest requirements.
