Planetary offset gearbox for a painting robot
Request from the customer
With the redesign of a paint roboter the CNC-Drives for the rotating axis of the spray head should be optimized. The so far used gear boxes of a competition had compared to the new specification much more better datas.
A Misalignment was realized with a planetary-spur gear combination. Through optimisation of the toothing and the bearing it was possible to increase the output torque 100 . The reduction of the gearbox length from 186 mm to 112 mm effected a decreasing of the gearbox weight of 30 %.
