Servo bevel gearboxes
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.
