New gear series also in enclosed version

This ready-to-install version simplifies assembly, allowing fast, easy integration of the compact and powerful gear heads in the drive train.

Nabtesco Precision Europe comments that applications such as robotics, rotary tables, machine tools and others require high torques, but offer only limited installation space. In addition, very fast and precise positioning movements have to be carried out with high payloads, and without backlash. This, according to Nabtesco, is exactly where the RV-N series shows its strengths: it is especially lightweight and compact, yet has a heavy-duty construction, which makes it suitable for new applications.

The compact design is achieved by means of a main bearing with an integrated inner race. High power density is achieved among other things by reinforcement of the eccentric shaft bearing.

The dimensions of the new gear are much more compact than the previous series – the power data remains at a comparable level with an average reduction by one size. Reduction of the weight by 40% reduces the mass inertia and improves the load conditions. Special heat treatment of all components during the production process ensures high thermal stability of the gears and a long service life. The series is available in diverse sizes with rated torques from 245 to 7000Nm.
