CompactSkive- Gear skiving system for gears

Berger Drive Tech is the new business unit for the internal and external gearing of industrial drive technology workpieces. We focus on gear skiving, a very demanding process in terms of axis geometries and tools, which offers very high productivity benefits - especially for the internal gearing of ring gears. Gear skiving replaces the "shaping" and "broaching" processes. Compared to gear shaping, it is around four to five times more productive. The advantages over broaching lie less in the machining speed than in the greater flexibility and lower tool costs.

Typical workpieces are internally toothed ring gears and externally toothed planetary gears of planetary gearboxes for the automotive industry, for agricultural machinery and for industrial gearboxes.

As planetary gears are also used in modern electric drives, gear skiving will continue to be a sought-after technology in the future.

Ring gear

In contrast to broaching, the skiving of an internally toothed ring gear can be readjusted at any time. For example, the flank line can be changed in relation to the angular position and crowning.

Tools

Various tool concepts guarantee an overall system that is optimally tailored to the respective application. Shank and disk-shaped tools are used as solid tools or indexable insert tools.

Planetary gearbox

The gears belonging to the planetary gear set can all be cut using the gear skiving process - internationally known as "skiving" or "power skiving". The high process accuracy guarantees low-noise running behavior of the e-gears.
