摘 要
为了提高农业机械化耕作的水平，加快实现农业现代化的步伐，根据现有某拖拉机离合器的工作情况及使用性能，完成某拖拉机离合器的设计。通过离合器的设计，使整车的性能更加优良。在设计离合器时首先应根据车型的类别、使用要求等合理选择离合器型式，并合理选择储备系数、压紧力、摩擦片尺寸等主要参数的具体值。之后进行离合器验算（主要进行磨损、滑磨功及发热验算）和对主要零件的强度计算，并完成了装配图和一些零件图的绘制。实现了离合器的良好使用性和结构工艺性。

Abstract
In order to increase the level of agricultural mechanization in farming, to accelerate the pace of agricultural modernization, according to the existing clutch of a tractor and use of the performance of the work to complete the design of the clutch of a tractor. Through the design of the clutch, so that more excellent performance vehicle. When the first clutch in the design should be based on the type of model, requirements for a reasonable choice to use the clutch type, and a reasonable choice reserve coefficient, compaction, and friction, such as chip size of the specific value of the main parameters. Checked after the clutch (mainly for wear, sliding wear and heat checking Gong) and the main parts of the strength calculation, and the completion of the assembly drawing and mapping a number of parts. To achieve good use of the clutch
and the structure of technology.
Key words : Tractor Clutch Reserve coefficient Pressed power
