Performance Research And Test Equipment Development Of Cycloid Steel Ball Reducer

As a new type of precision planetary ball transmission,the cycloid steel ball reducer breaks through the limitations of the original conventional reducer design ideas,abandons the conventional design mode of using gears as an intermediate medium to transmit mechanical force to the terminal,and is openly selected.The steel ball realizes the rapid transmission of mechanical force through the steel ball,reduces the relative movement of the transmission medium,thereby reduces the time interval in the transmission process,and reduces the noise generated by the transmission.However,due to the late start of domestic research on planetary ball drive and cycloid steel ball reducer,and there is no performance test equipment specifically for cycloid steel ball reducer in the domestic market,the reducer is still in the state of research and development.This paper analyzes the transmission principle and main performance indicators of the cycloid steel ball reducer,and designs a comprehensive performance test system for the cycloid steel ball reducer with LABVIEW as the test platform,which provides testing for the research and development of the cycloid steel ball reducer.Platform,and through performance analysis and test data,optimize the structure and transmission efficiency of the cycloid steel ball reducer.This article first introduces the basic structure,transmission mode and generation of the cycloid steel ball reducer,and explains the composition and basic principles of the cycloid steel ball reducer.Secondly,according to the test principles of the hysteresis,transmission error,transmission efficiency and shaft stiffness of the cycloid steel ball reducer,a global outline design of the test equipment of the cycloid steel ball reducer is carried out.The test system is driven by a servo system and loaded with a magnetic powder brake.After the induction equipment collects various data signals required in the test experiment,the automatic debugging of the function of the cycloid steel ball reducer is completed.According to the relevant performance indicators of the test system,the overall design of the test system and the analysis of the system driving device,torque sensor module and circular grating signal acquisition module are completed.At the same time,according to the system test plan that has been determined,the composition of the test system sensor,test platform,drive controller,load speed change mechanism and load motor hardware is explained.Through the analysis of the main performance of the test and its test plan,using LABVIEW2013 as the development platform,the realization of the software function of the test equipment is completed from three parts: the main program design and implementation,the equipment management module and the test module.Based on the analysis of software development requirements,the overall framework structure of the software system is obtained,and the functions of data collection,storage and analysis of various main performance indicators are realized.Finally,combined with the analysis of the performance and test results of the cycloid steel ball reducer,the currently widely used multi-objective particle swarm optimization algorithm is selected to establish a dual-objective optimization mathematical model of the cycloid steel ball reducer transmission mechanism.Under the constraint conditions.Taking volume and efficiency as the objective function,adopting the method of reducing the eccentricity to optimize the design of structural parameters,and then optimize the volume and efficiency of the cycloid steel ball reducer,complete the relevant simulation and experimental verification,and expand Research on the performance of cycloid steel ball reducer.
