Low-backlash planetary gearboxes

Request Custom orModified Product <
Encoder applications require an exceptionally high level of precision to make sure proper translation of motion into digital signals. Standard gearboxes frequently meet requirements for reliable speed reduction but produce gear backlash that impacts accuracy. Low backlash inline gearboxes provide a solution by improving smoothness and positioning precision while minimizing motor noise in high acceleration, high precision applications.
Improve Positioning Precision with Low Backlash Gearboxes
Ever-power is one of the world’s leading manufacturers of high-overall performance low-backlash gearboxes. Our SRX Series low backlash inline gearboxes are specially engineered to deliver the precision required for encoder applications. You can expect velocity reducers in a wide variety of equipment ratios and shaft sizes to meet up your unique needs.

Order an SRX Series inline rate reduction gearbox for the application or get in touch with us to find out more.
High-Functionality Low Backlash Inline Gearboxes
Ever-power’ SRX in-line rate reducers are rated for boosts to 3,000 RPM. These speed reduction gearboxes have a very low moment of inertia at the input shaft (as low as 0.015 gm-cm2). Two framework sizes are available, with equipment ratios from 4.96:1 up to 3,600:1. Low Backlash is definitely taken care of at 1.5 arc-minutes or better at any ratio.

Durable components and quality craftsmanship make sure that low-backlash gearboxes will deliver years of dependable performance. The housings are manufactured from black anodized aluminum, with 303 stainless gears and shafts. These components exhibit outstanding corrosion level of resistance, making SRX Series low backlash gearboxes ideal for harsh working environments.

low-backlash planetary gearboxes – compact and highly precise
The new planetary gearbox series from Ever-power includes the high-end gearbox lines GSD (flange gear), GSB (inline) and GSBL (angle gear) and also the high-end economy GSN and GFE lines. Particularly ideal applications for the brand new range are those that place the highest demands on positioning precision, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are designed to meet the highest creation requirements – all lines include precision ground helical gearing, single-piece planetary carriers and complete needle bearings.
The EP high-end gearbox lines are constructed in a space-optimized, two-stage style. Due to the lower torque values, the input stage can be dimensionally smaller compared to the result stage. Its short design makes the GSD series the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD range makes it an ideal fit for highly powerful applications where highest positioning and swiftness accuracy is required. The flange result creates highest torsional rigidity. For the lodging of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or more. The GSB line means high performance in combination with low backlash and high precision. Its robust, one-piece housing allows for a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL collection provide same advantages as the EP line; the right angle shape makes the GSBL line the perfect match for all powerful applications where space is bound.
The high-end economy lines combine high performance with economic efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing offers been especially designed to reach high torques that beat the competition for units of the same size. All planetary carriers are manufactured as a cage made from solid material. This increases noiseless operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing band ensures maximum dirt and splash water protection in accordance with protection class IP65 in all lines.
