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.
