Special servo gears have been developed for the requirements of highly dynamic servo motors. The design is formed by the proven series of bevel and worm gears.
The combination of a large number of motor flanges and a plug-in, backlash-free clamp coupling enables an adaptation to most servo motors. The modular system also makes it very easy to subsequently change the motor flange and the motor-side coupling half.
Servo gears (precision gears) are high-precision and highly dynamic servo
drive solutions. These high-performance gears are up to todays high demands in
every respect. It is not without reason that they are used worldwide in the
automotive industry, among other things.
Whether application-specific drive solutions for the construction of
special machines or series products for general machine construction, the
modular system offers a wide range of drive solutions of the highest product
and process quality at a competitive price/performance ratio.
