Based on the multi-body dynamics theory, paper builds the virtue prototype of the RV reducer with Adams software. By apply the cycloid gear equation with modification to create the backlash between cycloid gear and the pin gear. Build the backlash model between eccentric shaft and bearing with definition of constraint and function method. By using the MNF file to consider the deformation of the cycloid, pin gear and planet carrier. The dynamic flexible-rigid model of the coupled RV reducer was established. Then output curves of rotation rate, acceleration, force and angle inaccuracy were conducted. Then change the value of the backlash and to study its effect on the transmission error.The simulation results of the RV reducer provides the foundation for the further study of the precision analysis.

“…e performance parameters of the reducer generally include the no-load friction torque, torsional stiffness, and transmission efficiency [3,7,8]. Many scholars have extensively studied the optimization of the internal parts [9], overall structure [10], and dynamic performance of the reducer [11,12]. However, these studies are limited by measurement means and equipment, which severely hinders the improvements to the reducer performance.…”

The measurement of input and output torque of a precision reducer, the core component of an industrial robot, plays a vital role in evaluating the robot's performance. The TMSIS and TMSOS of a vertical cylindrical high-precision reducer detector were designed and investigated in this study to realize the accurate measurement of input and output torque of the reducer. Because a transmission chain connects the torque transducer and the reducer, the characteristics of the inevitable additional torque are analyzed in detail. A torque calibration device is developed to realize the calibration of the torque measurement system. The readings of the torque calibration device are compared with the data of the instrument’s torque measurement system to realize the instrument's torque calibration. The improved particle swarm optimization and Levenberg–Marquardt algorithm-based radial basis function neural network is used to compensate for the error of the torque measurement system. The parameters of the RBF neural network are settled according to the characteristics of the additional torque and the torque calibration results. The experimental results show that the torque measurement accuracy of the torque measurement system can reach 0.1% FS after torque calibration and error compensation.

The input and output torque testing is crucial for improving the quality of Industry robot reducers. In this study, the TMMISR and TMMOSR for a vertical-type robot reducer detector were designed. The length of measurement chain between the torque transducer and the tested reducer was shorten. The overall stiffness of this instrument has been improved through structural optimization. The characteristics of the two main parts of the torque-measurement errors were also analyzed. A high precision torque calibrator with a standard torque output is used to handle the torque calibration process. An error compensation method based on a backpropagation neural network was adopted for the error compensation process in this study. After error compensation, torque-measurement precision of 0.1% can be achieved by the reducer detector over the full torque measurement scale, and the instrument can be used for both static and dynamic measurements.
