On the basis of the RV-E series, Nabtesco has prepared extremely compact, light and strong gears dedicated to industrial robots - the RV-N series.
They are used in applications where high transitions are required and the installation space is limited. The compact design is possible thanks to the main bearing, which is integrated in the inner ring.
Strengthening the axis of eccentricity allows for the production of high power density. In addition, all the elements of the gear have been optimized with the help of the finite element method and subjected to a special heat treatment.
An efficiency ratio of up to 85 %, shock resistance of 5 times the rated torque and extreme precision make the eccentric gears of the RV-N series an outstanding choice for diverse robotic applications. Robots benefit from excellent load conditions due to the reduced weight and lower mass inertia. The RV-N series is also used in medical technology, in machine tools and in positioning applications.
