On the basis of the RV-E series Nabtesco has with the RV-N series once again developed more compact, lighter and more powerful precision gears. The compact design is ensured by a main bearing with integrated inner ring. The high power density can be achieved, inter alia, by reinforcing the eccentric shaft bearing. There are various sizes with nominal torques from 245 to 7000 Nm.
In applications such as robotics, but also in turntables, machine tools and many other applications, although high torque capabilities are required, but there is often little space available. Furthermore, very fast and precise positioning movements with high loads without ringing must be implemented. This is exactly where the new RV-N series comes into its own: It is particularly lightweight, compact and yet powerfully engineered to offer new applications.
Compared to the predecessor series, the dimensions of the gearboxes are significantly more compact - with comparable performance data, they could be reduced by an average of one size. A reduced 40% weight ensures lower inertia and thus improved load conditions. Due to a special heat treatment of all components within the production process, a high temperature resistance and a significantly extended service life of the gear units are guaranteed.
