摘 要 本次设计的取力器是与EQ1181型载货汽车DF6S850Abstract This design requires access edge with transmission DF6S850 of EQ1181 Truck matching, Request： the maximum output torque transmission 850Nm，get maximum output torque of Power 450Nm; to meet the strength and stiffness requirements; high transmission efficiency; good processing process and assembly process of. The devices take power from the power form of power transmission from the left side of cover, and the overall structure of the form of a two-axis, taking power from the device to a dedicated power transfer between the devices can be used mechanical transmission. First of all, the EQ1181-type vehicle in accordance with engine and transmission parameters and a dedicated device used to determine the parameters of Power from the transmission ratio, determined in accordance with the assembly of space inside edge from the center distance of two gear range, under the power transmission gear parameters taken from the two gear power devices module, pressure angle, tooth width and other parameters. After the shaft, gear and keys to check to verify the reliability of the components. Then, check our complete device assembly drawing and components drawing. Finally, the preparation of parts of the processing process. Analysis by calculating the force from a reasonable structure design, manufacturing process is simple, the basic can be used in actual production and use, meet the design requirements. Key words：truck;transmission; power take off; design;technology. 目 录 第一章 绪 论 1 1.1取力器简介 1 1.2取力器分类 1 第二章 取力器方案设计及论证 2 2.1取力器设计要求 2 2.2取力器方案论证 2 2.2.1已知东风EQ1181发动机、变速器及专用装置参数： 2 2.2.2方案论证 3 第三章 取力器参数设计计算 5 3.1 取力器传动比及齿轮齿数的确定 5 3.1.1取力器传动比的确定 5 3.1.2取力器齿轮齿数的确定 5 3.2取力器中心距 7 3.3取力器齿轮计算与校核 8 3.4取力器轴计算与校核 14 3.4.1 取力器一轴的设计过程： 14 3.4.2取力器二轴设计过程： 18 3.5取力器轴承的选用 22 3.5.1取力器一轴轴承 22 3.5.2取力器二轴轴承 23 3.6取力器键连接设计 25 3.6.1取力器一轴平键 25 3.6.2取力器二轴滑移花键 25 3.6.3取力器二轴法兰花键 26 3.6.4取力器齿轮2齿圈 26 第四章 主要零件加工工艺过程 28 4.1取力器二轴的加工工艺过程 28 4.1.1取力器二轴加工工艺 28 4.1.2二轴中间花
