1．引言
耕作机是一种用于农业水稻中的小型机动设备，努力减少耕作机的尺寸和重量是优化变速箱设计的重点，一些发表的论文中也谈到这个主题。但是，这种研究往往忽视齿轮润滑。本文介绍了变速箱的优化设计的数学模型包括以下因素：接触疲劳强度模型，弯曲疲劳强度，不干预和边界条件，润滑膜厚度比。这将为优化设计的一个圆柱齿轮减速箱提供有用的参考。





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.
