Low-backlash planetary gearboxes

Request Custom orModified Item <
Encoder applications require an exceedingly advanced of precision to ensure proper translation of movement into digital signals. Regular gearboxes often meet requirements for dependable speed decrease but produce equipment backlash that impacts precision. Low backlash inline gearboxes give a solution by enhancing smoothness and positioning accuracy while minimizing motor sound in high velocity, high precision applications.
Improve Positioning Accuracy with Low Backlash Gearboxes
Ever-power is among the world’s leading producers of high-performance low-backlash gearboxes. Our SRX Series low backlash inline gearboxes are specifically engineered to provide the precision necessary for encoder applications. We offer swiftness reducers in a wide selection of equipment ratios and shaft sizes to meet up your unique needs.

High-Overall performance Low Backlash Inline Gearboxes
Ever-power’ SRX in-line quickness reducers are rated for speeds up to 3,000 RPM. These speed decrease gearboxes have a very low minute of inertia at the insight shaft (only 0.015 gm-cm2). Two body sizes can be found, with gear ratios from 4.96:1 up to 3,600:1. Low Backlash is maintained at 1.5 arc-minutes or better at any ratio.

Durable materials and quality craftsmanship ensure that low-backlash gearboxes will deliver years of dependable performance. The housings are produced from black anodized light weight aluminum, with 303 stainless steel gears and shafts. These materials exhibit outstanding corrosion resistance, producing SRX Series low backlash gearboxes perfect for harsh working environments.

low-backlash planetary gearboxes – small 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) as well as the high-end economy GSN and GFE lines. Particularly appropriate applications for the new range are those which place the best demands on positioning accuracy, operating noises, working smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest production requirements – all lines are equipped with precision floor 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. Because of the lower torque ideals, the input stage is dimensionally smaller than the output stage. Its short style makes the GSD collection the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD line makes it the perfect fit for highly dynamic applications where highest positioning and velocity accuracy is necessary. The flange output generates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or higher. The GSB line stands for 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 offer the same advantages as the EP range; the right angle form makes the GSBL range an ideal match for all dynamic applications where space is limited.
The high-end economy lines combine powerful with financial efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing has been especially made to reach high torques that defeat the competition for products of the same size. All planetary carriers are produced as a cage created from solid materials. This increases silent operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water safety relative to protection course IP65 in every lines.
