Three-phase gear-motor DR series

helical gearparallel-shafthollow-shaft

This series is compact and easy to mount. Flange-, foot- and hollow shaft-mounted versions, or combinations of these mounting options are available. These gearboxes are of a modular design. Output shaft and flange can be mounted to standard hollow-shaft gearboxes without modification of the gearbox. The housing has mounting points on both sides, allowing mounting from either side. The hollow-shaft gearboxes have new mounting options also for the input side. Input possibilities are standard (IEC B5 or B14), direct coupled or with solid input shaft. A combination with other gearbox types is possible with minimum change. In applications where efficiency and strength are important, hollow-shaft gearboxes are preferred to worm gearboxes. Hollow-shaft gearboxes can withstand higher overhung loads than other gearbox types. Specifications and Advantages Monoblock housing design, Wide ratio, torque range and two or three stages can be in same housing Reduction can be increased up to six stages, Standard IEC B5 or B14 motor flanges, Electromagnetic brake option, Long life bearings, GG20 and GGG40 cast iron housings, 58-62 HRc hardened and grinded gears
