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 28,000 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-optimised 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.
RV-2800N: The biggest precision gear in the world
The RV-2800N achieves a rated torque of 28,000 Nm, which makes it the biggest precision gear in the world. A robust and compact design, together with high precision, makes the gear suitable for the most demanding applications. Even entire vehicles can be moved effortlessly with the component sets. The extra large gear is designed for use in applications that require precise positioning of large loads. Such applications include robotics, automotive construction, the glass industry, shipbuilding, mining and cranes. A powerful and efficient alternative to hydraulic applications.
