Groschopp offers a new gearbox called "Angulus" for torques up to 50 Nm. Its construction as an angle gear contributes with a high efficiency to a good energy balance. Further advantages result from smooth contours and surfaces. The angle gear consists of a spur gear and a bevel gear stage. This design principle, especially in comparison with the simply constructed worm gears, causes a significantly higher efficiency.
This is particularly evident in smaller gear ratios where the new transmissions can reach just under 90%. Translations from approx. 6: 1 to 60: 1 are possible with this series. In the higher range, the values are still around 88%. Here the differences to the worm gear are even clearer. The drive speed can be up to 3.600 min-1 be. This enables the gearboxes to reach torques of up to 50 Nm.
