Title : Design and Analysis of Crawler Combine Harvester Gearbox

Abstract :

For the current combine harvester cutting width, feeding capacity and the whole machine quality are gradually increasing, resulting in gearboxes with glued teeth, brake housing rupture and brake pad burning phenomenon due to insufficient load-bearing capacity. In this paper, a crawler combine harvester gearbox is designed. Firstly, the gearbox is modeled by theoretical design calculations and using SolidWorks 3D drawing software. Then using ANSYS software, stress analysis and modal analysis are performed on the driveline to verify the feasibility of the gearbox. Finally, the gearbox is manufactured and installed on the combine harvester chassis. And designing tests to verify the transmission performance and load carrying capacity of the gearbox. The results show that when the combine harvester is fully loaded (7t) at high speed (2m/s) on a wet and soft mud field, the gearbox output half-shaft is subjected to the maximum torque with a peak torque of 2238.5N-m. And when the harvester is fully loaded and steering in the field in second gear (1.5m/s), the peak torque of the gearbox output half-shaft reaches 2760.2N-m, both of which meet the rated torque value of the gearbox. The matching power of the gearbox designed in this paper reaches 85~95kW, which can meet the continuous and stable operation of combine harvester under heavy load. This study provides a method and reference for the design and development of combine harvester gearboxes.
