Description
Summary:In order to study the influence of various factors on the transmission error of an RV (rotate vector), the working principle and structure of reducer are analyzed, and the ratio is calculated. The mass-spring equivalent model is used to calculate the force, and the mathematical model of transmission error is established and combined with the translation-torsion coupling model. The transmission performance of the RV reducer was characterized using ADAMS and compared with the mathematical model. The effects of three different modification methods and load analysis techniques at different output terminals on the transmission error and frequency ratio are compared. Increasing the meshing clearance between cycloid gear and pin tooth will increase the error. An RV reducer test bench is established to compare the influence of different speeds and torques on transmission error. The analysis shows that the gap between the secondary cycloidal pin gear transmission and the crankshaft installation error is the main cause of the tooth gap. The simulation and experimental results verify the accuracy of the mathematical model.
