RV-N
Solid shaft component sets

Compact construction, reduced weight: ideal for robotics

We developed the gear sets of the RV-N series as very compact, lightweight and high-performance solid shaft gears. These gears are used in applications with limited space that require high torque performance. Perfect for robotics!

High shock load
(up to 5 times the rated torque)

Extremely precise and low-wear,
hysteresis loss < 1 arcmin, long service life

Finely graduated sizes,
rated torques of 245 Nm to 7,000 Nm

Unbelievably powerful with exceptional load capacity

RV-N cycloidal gears are very compact due to the main bearing with an integrated inner race. The reinforcement of the crankshaft bearing achieves very high power density. In addition, all gear components are FEM-optimized and are manufactured using state-of-the-art production processes.

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.
