1．引言
耕作機(jī)是一種用于農(nóng)業(yè)水稻中的小型機(jī)動(dòng)設(shè)備，努力減少耕作機(jī)的尺寸和重量是優(yōu)化變速箱設(shè)計(jì)的重點(diǎn)，一些發(fā)表的論文中也談到這個(gè)主題。但是，這種研究往往忽視齒輪潤滑。本文介紹了變速箱的優(yōu)化設(shè)計(jì)的數(shù)學(xué)模型包括以下因素：接觸疲勞強(qiáng)度模型，彎曲疲勞強(qiáng)度，不干預(yù)和邊界條件，潤滑膜厚度比。這將為優(yōu)化設(shè)計(jì)的一個(gè)圓柱齒輪減速箱提供有用的參考。





1. Introduction
A tillage machine is a small motorized device used in rice agriculture. Efforts to reduce the size and weight of tillage machine shave focused on optimizing the design of the reduction gearbox。these have been the subject of several published reports. However，this research has tended to ignore the gear lubrication. This paper describes a mathematical model of an optimal gearbox design, Including the following factors: contact fatigue strength, bending fatigue strength, nonintervention and boundary conditions, and lubricant film thickness ratio. This will provide a useful reference for the optimizing the design of the cylindrical gear-speed reducer.
