Cycloidal gearboxes for high end applications

It was the proven track record of RA Rodriguez as high precision gearbox solution provider that resulted in Nabtesco choosing the company as the sole distributor of its products in the UK. “RA Rodriguez offers a comprehensive range of solutions for high-end applications which makes it a perfect partner for Nabtesco in the UK,” commented Daniel Obladen, head of sales for general industries at Nabtesco Precision Europe. “We greatly value the technical expertise and applications knowledge the company brings to our partnership.”

It is for applications where backlash and positioning accuracy are critically important that Nabtesco has the greatest potential. They are highly robust products with a very long service life. The increase in backlash in cycloidal gears is very low over extended periods and they also enable reduction in ratios from 30:1 to more than 300:1 without additional pre-stages that are necessary in standard planetary gears.

Cycloidal gears are also more compact – around 50% shorter than their planetary counterparts – and are also lighter. In addition, they offer 500% higher overload protection. Nabtesco cycloidal gearheads owe these properties to their special design principle. The gear teeth need no gear in the output stage and are not subjected to shear forces, making them exceptionally efficient, precise and robust. The power transmission, via pins and rollers, ensures high efficiency and long life and extremely low backlash. And virtually complete contact within the cycloidal pin construction and the even force distribution enable a high load-bearing capacity.
