中型船式拖拉機(jī)（機(jī)耕船）傳動(dòng)系統(tǒng)設(shè)計(jì)
摘 要
　　　本文分析了本課題研究的目的及意義，對(duì)機(jī)耕船傳動(dòng)系統(tǒng)的發(fā)展現(xiàn)狀與研究趨勢(shì)進(jìn)行了初步探討。在對(duì)機(jī)耕船的作業(yè)環(huán)境以及農(nóng)藝需求進(jìn)行研究分析之后，進(jìn)行了離合器的選型和動(dòng)力輸出方式的選擇。在此基礎(chǔ)上選擇機(jī)耕船四驅(qū)傳動(dòng)系統(tǒng)中變速器與分動(dòng)器的結(jié)構(gòu)形式并確定了傳動(dòng)方案。依照所確定的傳動(dòng)方案，展開變速器與分動(dòng)器具體結(jié)構(gòu)以及內(nèi)部零部件的設(shè)計(jì)計(jì)算，包括傳動(dòng)齒輪、軸以及換擋裝置的設(shè)計(jì)。該四驅(qū)傳動(dòng)系統(tǒng)主要根據(jù)我國(guó)目前機(jī)耕船的發(fā)展現(xiàn)狀而設(shè)計(jì)，為改善目前主要生產(chǎn)的后輪驅(qū)動(dòng)三輪式機(jī)耕船，加大了牽引功率，四驅(qū)系統(tǒng)對(duì)深泥腳水田以及旱田的農(nóng)藝適應(yīng)性更強(qiáng)，提高勞動(dòng)生產(chǎn)率，有利于減輕勞動(dòng)強(qiáng)度。四輪驅(qū)動(dòng)機(jī)耕船是今后機(jī)耕船的發(fā)展趨勢(shì)。

ABSTRACT
　　　This paper analyzes the purpose and significance of researching this project, and gives a preliminary discussion on the current development and research trends of transmission system of boat tractor. After analyzing the operating environment and the agronomic needs of the boat tractor, this paper shows the selection of clutch and the form of Power Take Off. On these basis, choosing the structure of gearbox and Sub-actuator in system of the boat tractor to determine the transmission scheme. According to the determined transmission scheme, expand the design of gearbox and Sub-actuator and the internal parts in them, including the design of the transmission gears, shaft and shifting device. This design of the four-wheel drive transmission system is primarily based on the current development status of the boat tractor in our Country, to improve the rear-wheel drive three-wheel boat tractor which is now being mainly produced. In this new transmission system, the traction power is increased and it enhances the tractor’s adaptability in the working environment, which can increase labor productivity and reduce labor intensity. The four-wheel drive boat tractor will be the trend of development in this field.
