Study on the Design of Composite Transmission System for Crawler Type Full-Feeding Combine Harvester

Abstract:

Transmission system is an important part of combine harvester, and is the main indicator to measure the level of technology. This paper presents the design of a composite hydraulic mechanical transmission system for combine harvester. The system consists of engine, variable pump, quantitative hydraulic motor, planetary reducer, driving wheel, crawler etc. Author analyzes the continuous variable speed regulation characteristics of transmission; determines selection method of hydraulic components and mechanical parameters. Composite transmission system can make the engine is close to full load operation, improve combine harvester productivity and fuel economy. By optimizing the transmission system, combine harvester can reduce speed, increases the torque, realizes continuous variable speed. Practice has proved: this dynamic composite transmission system with fast response, high efficiency, and reliable, low failure rate. At the same time, combine harvester has the advantages of simple operation, forward, backward or turning without shifting, greatly reduce the labor intensity of the operator.
