low-backlash planetary gearboxes – compact and highly precise
The brand new planetary gearbox series from Ever-power includes the high-end gearbox lines GSD (flange equipment), GSB (inline) and GSBL (angle gear) and also the high-end economy GSN and GFE lines. Particularly appropriate applications for the brand new range are those which place the best demands on positioning precision, operating noises, working smoothness, bending rigidity and transmitted torque. The planetary gears are designed to meet the highest production requirements – all lines include precision surface helical gearing, single-piece planetary carriers and full needle bearings.
The EP high-end gearbox lines are constructed in a space-optimized, two-stage design. Due to the lower torque values, the input stage can be dimensionally smaller than the output stage. Its short design makes the GSD collection the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD collection makes it an ideal fit for highly dynamic applications where highest positioning and rate accuracy is necessary. The flange output produces highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or higher. The GSB line means high performance in mixture with low backlash and high precision. Its robust, one-piece housing permits a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL series provide same advantages as the EP line; the right angle shape makes the GSBL collection the perfect match for all powerful applications where space is bound.
The high-end economy lines combine powerful with economic efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing has been especially designed to reach high torques that beat the competition for models of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases noiseless operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water protection relative to protection class IP65 in every lines.
