The RV-C Hollow Shaft reducer provides a center thru-hole with a component type configuration for more system design flexibility and greater space saving options. The unit incorporates rolling contact elements to provide high efficiency, long life and extremely low backlash as well as an off-center second stage reduction designed to limit vibration and inertia while increasing ratio options. The reducer also incorporates a set of large, internal angular support bearings that provide large moment capacities and negate the need for external support devices - reducing design time and installation costs.
The RV-C Hollow Shaft is also available in Right Angle configurations for greater space saving capabilities. Please Contact Nabtesco for further information.
LONG LIFETIME AND RELIABILITY
The Nabtesco Reducer consists of a patented two-stage cycloidal design that provides large torque, high-ratio and significant shock-load capabilities with extreme precision and excellent quality. The RV utilizes rolling contact elements to reduce wear, extend life and lower backlash with the unique pin and gear structure of the cycloidal design providing higher shock resistance than traditional reducers and further reducing backlash. The reducer also incorporates a set of large, internal angular support bearings that provide large moment capacities and negate the need for external support devices.
The virtually symmetrical gear design and the support of all shafts by roller bearings guarantee a constant performance during the lifetime and allow short time peak loads
of up to 5 times the given rated torque (i.e. for emergency stops).
