| Our country is a large agricultural country, with economic development, modern agricultural equipment to a stage of rapid development of much-needed degree of development of agricultural mechanization will directly affect the overall level of the entire agricultural development, while the rice is of relatively important food crop, can fully realize the full planting rice mechanization will be the realization of China’s agricultural modernization has great significance.The quality of the working conditions of the rear axle will directly affect the entire transplanter walking speed and quality of field operations. Kinetic of studies aim is to optimize the whole gear transmission, a more accurate grasp of dynamics in the process of gearing by simulating the dynamic equations, so as to optimize the design to improve gear carrying capacity and security to provide an effective theory reference. Based on a simple comparison of domestic and foreign rice transplanter analysis of the development process,the basis of principles of organization, theoretical analysis and simulation of a combination of methods, the overall structure of the rear axle and the optimized design of key components. The main contents and conclusions are as follows:(1) In the simplest analysis and comparison of the current domestic and international dynamics of gear based on the principle of using the Rayleigh method to derive formulas equivalent quality gear and shaft assembly time, and studies have investigated the Kinetics of of the process model Related parameters: the equivalent stiffness, equivalent damping.Finally, the calculation gives a matrix form of single-stage gear deputy kinetic model. For in-depth study of gear transmission. Rear axle gear transmission gears by ten, in order to ensure transmission reliability, a key part of the gear transmission Kinetics of were studied to analyze the large case load conditions force transmission, gear transmission system is designed to provide reliable the design basis.(2) Designed rear axle wheel deceleration clutch brake system, using the system to complete asynchronous brake wheel transplanter about to complete transplanter pivot turn,and when the field work can solve the problem of power shortage.(3) In this paper, the design of key components of the rear axle system was running three-dimensional modeling and virtual assembly, and rear axle gear drive system established kinematic simulation ADAMS, by analyzing the size of the gear meshing force between the levels of each angular velocity curve gear, the gear system calculated transmission efficiency, rationality rear axle gear transmission further validate the design.(4) To understand the transplanter rear axle gear during vibration gear, using ANSYS finite element analysis software transplanter rear axle gear transmission gear key modal analysis, by studying its natural frequency, and with the field transplanter the actual vibration when operating conditions compared to verify the feasibility of the pinion design,optimized design for the structure of the rear axle gear transmission gears provide a theoretical basis. |
