Kinetic Analysis And Research Horizontal Spindle Key Components Of The Intermediate Shaft System

With Xinjiang cotton industry’s continuous development and its advantage’s gradual establishment,mechanized harvesting is an important part for achieving full mechanization of cotton production. Atpresent, domestic cotton picker had filled up the domestic blank and began mass production, but the coretechnology is monopolized by foreign countries, while the domestic cotton picker decreased gradually inthe possession of Xinjiang. Therefore, accelerating the pace of research and localization of domestic cottonpicker has a positive effect on improving the efficiency and the performance reliability of domestic cottonpicker.Domestic cotton picker’s unstable performance can easily damage the pick ingot or the intermediateshaft. Intermediate shaft’s damage may be due to the alternating load. As the main working parts ofintermediate shaft system, intermediate shaft’s structure has a significant impact on the working state of theentire system. Therefore, optimizing the structure of the intermediate shaft system is very important. In thispaper, the theoretical mechanics and the finite element modal analysis technology were used to research theforces of the intermediate shaft in working conditions, and the ADAMS software was used to simulate theworking status. The research results can provide basic data for intermediate shaft system’s optimization andthe experimental study, and they have some theoretical and practical value. The main researches are asfollows:(1) Structural characteristics and operating conditions of cotton picker intermediate shaft system wereanalyzed; power distribution transmission and power transmission line of cotton picker cotton picker headwere analyzed; according to the aviation field research by the number of teeth of cotton picker transfer boxshaft speed range and picking head of each gear, speed range of level ingots, picking roller and doffing diskwere calculated. The knowledge of theoretical mechanics was used to analyze the strength and stiffness ofthe intermediate shaft in the normal operating condition, and test whether it meets the design requirements.(2) Some key components’ three-dimensional solid model of the intermediate shaft system were builtby Solidworks software. Because the Solidworks gear modeling function is weak, so interpolation methodand spline curves are used to generate gear involute and three kinds of modeling method of gear arediscussed. And the intermediate shaft system’s virtual assembly and interference inspection were carriedout.(3) The ADAMS software was used to simulate the working conditions of intermediate shaft system,then clutch connection plate’s displacement changes and the pressure spring’s force changes were analyzed.(4) Intermediate shaft system’s statics characterization were analyzed by the finite element softwareANSYS-Workbench, and the intermediate shaft’s equivalent stress, strain and displacement parameterstime course when the cotton picker is stable were got. Because there was more contact between gears in theentire transmission system, the force of a gear pair in contact was analyzed by ANSYS Workbench, and theresult of simulation is analyzed for the follow-up transient stress analysis of gear pair as a foundation.
