  • Off-Set motor mounting for access to Hollow Shaft
  • Very compact with high torsional rigidity
  • Component version for more design flexibility
  • Integrated Angular bearings for large thrust & overhung moment capacity
  • High Ratio availability (up to 400:1) without increasing gearbox size
  • Torque capacity up to 5X rated torque (E-Stop)
  • The RV-C Hollow Shaft reducer provides a cent
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).


DESIGN BENEFITS

Integrated Angular Support Bearings increase reducer rigidity as well as provide the reducer with the ability to support large external moments. Thus eliminating the need for external support devices, reducing the number of components required and increasing reliability and reducing overall cost.
 
100% Continuous Contact of the cycloidal pin & gear teeth design provides high shock load capacity and very low backlash since forces are distributed throughout the reducer.
 
The Patented 2-Stage Reduction Mechanism reduces vibration due to the lower speed rotation of the two cycloidal gears while the reduced input coupling size lowers inertia. A wide variety of ratios are possible by simply changing the first stage spur gear combinations.
 
The use of Rolling Contact Elements throughout the reducer helps to provide an excellent starting efficiency; low wear with long life expectancy, and low backlash.


HIGH POSITIONING ACCURACY
 


The angular transmission accuracy between the input and output shaft is described by the transmission error. The test result beside exemplarily shows the superior precision of these gears.
 
Measurement: With the input gear fixed, the rated torque is applied to the output shaft in both directions and the elasticity is measured. At zero load (dead center), the distance delta-phi between upper and lower boundary graph of the hysteresis area is maximum 1 arc min.
