Industrial Speed Reduction Ratios Nabtesco Cycloidal Gearbox Reducer RV-40E
Among the total cost of industrial robots, the proportion of core
components is close to 70%, and the proportion of reducers, servo
motors and controllers is 32%, 22% and 12% respectively.
The technical barrier of the reducer is the highest among the core
components. In a precision - fitted system, small deviations in
clearance or interference fit can cause multiple differences in
contact stiffness / engagement stiffness, which in turn can cause
changes in motion parameters.
The application of reducer in industrial robots. For multi - joint
industrial robots, the type of reducer may vary depending on the
load, but a precision reducer is required for each joint.
Therefore, the number of reducers required for a general - purpose
robot is 4 - 6 sets. In addition, for the existing industrial
robots, the reducer itself has a rated working life and needs to be
replaced periodically; while the working life of the industrial
robot is generally 8 - 10 years, during which the reducer acts as a
transmission and load - bearing component, and wear is inevitable.
Therefore, a large number of reducers are required for the
maintenance and repair of industrial robots.
Based on the comprehensive import performance of Zhenkang RV
gearbox, its market competitiveness lies in reasonable prices. With
higher cost performance, the same quality and installation
interchangeability, it has won widespread recognition in the
market. Since 2012, more than 30,000 RV gearboxes have been put on
the market, and user feedback has been good. At the same time, in
2018, Zhenkang RV gearbox has a production capacity of 30,000
units, and has been favored by more and more robot manufacturers
with its short delivery time, high cost performance and stable
quality. On December 18, 2016, the 25,000 square meter factory
building of Nantong Zhenkang Welding Robot Industrial Park has been
basically completed. After the project is fully put into operation,
the park's development goal is to produce 200,000 RV gearboxes and
10,000 welding robots.
