High Load Reduction Gear RV E, Cycloidal Pinwheel Reducer Nabtesco RV-450E​

 


Globally, the precision reducers used in the robot industry can be divided into Cycloidal Gear reducer, harmonic reducers and SPINEA reducers. The market share of the three is about 40%, 40%, 20%. Among them, RV gearbox and harmonic reducer are the most mainstream precision reducers for industrial robots.


The RV gearbox has the characteristics of large transmission ratio, high transmission efficiency, high motion precision, small backlash, low vibration, high rigidity and high reliability. In the articulated robot, the RV gearbox is generally placed at a heavy load such as the base, the boom, and the shoulder.

 

In the production process, industrial robots usually perform repeated actions to complete the same process.

In order to ensure that industrial robots can reliably complete process tasks in production and ensure process quality, the positioning accuracy and repeat positioning accuracy of industrial robots are very high demanding.

Therefore, in order to improve and ensure the accuracy of industrial robots, it is necessary to use a reducer.

Generally, the robot joint reducer requires short transmission chain, small volume, high power, light weight and easy control.

Currently widely used robot reducers mainly include RV reducers and harmonic reducers.


For 20 years, Nantong Zhenkang has been focusing on the development and production of the core components of precision robots, precision motors and precision reducers, from the beginning of the printing motor, to the later wire feeders and automated welding trolleys, to the current RV reducers. In 2010, it developed the RV reduction gear for industrial robot transmission core components and series AC servo motors, which have been put into mass production.

 

 

Working principle of Cycloidal Gear reducer

 

  1. The RV drive is a new type of transmission developed on the basis of cycloidal pinwheel drives.
  2. The RV reducer consists of an involute cylindrical gear planetary reduction mechanism and a cycloidal pinion planetary reduction mechanism.
  3. The involute planetary gear is integrated with the crankshaft as an input to the cycloidal pinion drive section.
  4. The crankshaft drives the cycloidal wheel for eccentric motion.
  5. The crank rotates clockwise clockwise for 1 week and the cycloidal wheel moves 1 tooth counterclockwise.
  6. The core components of the RV reducer are the pin housing, the crank shaft and the cycloidal wheel.

Structure principle of Cycloidal Gear reducer

 

High Load Reduction Gear RV E, Cycloidal Pinwheel Reducer Nabtesco RV-450E 0

  • Input shaft/planetary gear

Form the'1st stage planetary gear reduction, realizing different gear reduction ratio through the changing of the gear

 

  • Pin shell/pin/cycloid gear

Form the 2nd stage gear reduction, achieving high rigidity and high accuracy through the cycloid meshing rate higher than 80% and the nearly zero - backlash quality fit.

  • Crank shaft/output shaft

Realizing the transmmision and output of the torque by connection the 1st and 2nd stage gear reduction mechanism.

  • Support bearing

Provides extremely high bending moments and load bearing capacity.

 


* Please refer to the installation drawing for the actual mounting.
