摘 要

曲轴是汽车发动机的关键零件之一,其性能好坏直接影响到汽车发动机的质量和寿命.曲轴在发动机中承担最大负荷和全部功率,承受着强大的方向不断变化的弯矩及扭矩,同时经受着长时间高速运转的磨损,因此要求曲轴材质具有较高的刚性、疲劳强度和良好的耐磨性能。发动机曲轴的作用是将活塞的往复直线运动通过连杆转化为旋转运动,从而实现发动机由化学能转变为机械能的输出。

本课题是柴油机曲轴的加工工艺的分析与设计进行探讨。工艺路线的拟定是工艺规程制订中的关键阶段,是工艺规程制订的总体设计。所撰写的工艺路线合理与否,不但影响加工质量和生产率,而且影响到工人、设备、工艺装备及生产场地等的合理利用,从而影响生产成本。

所以,本次设计是在仔细分析曲轴零件加工技术要求及加工精度后,合理确定毛坯类型,经过查阅相关参考书、手册、图表、标准等技术资料,确定各工序的定位基准、机械加工余量、工序尺寸及公差,最终制定出曲轴零件的加工工序卡片。

Abstract

The car engine crankshaft is one of the key parts and its direct influence on the performance of the quality of life and the car engine crankshaft in engine. For maximum load and power, with all of the changes direction, bending and torque through long run, so the crankshaft material wear high rigidity, fatigue strength and wear resistance. Engine crankshaft role of piston is reciprocal linear motion through the link into the rotary motion, thus realize engine by chemical energy into mechanical energy output.

This topic is only diesel engine crankshaft process analysis and design are discussed. The process route plan is the key stage procedure formulation of regulations, is the overall design process. Which route reasonable or not, not only influence processing quality and productivity, and affect worker, equipment, and process equipment and production sites, which affect the reasonable utilization of production cost.

Therefore, the design is in the careful analysis of the crankshaft parts processing technical requirements and machining precision, reasonably determine the blank type, after consulting relevant reference, manuals, charts, standards, technical data to determine the locating datum, mechanical process and procedure limits.but dimensions and tolerances, eventually developing a crank parts processing process card.
