装载机实现变速的重要部件之一就是变速箱的箱体。通过将发动机中产生的动力在变速箱的箱体中实现变速,然后再传送到输出部位进行输出。在箱体内,有传动轴,齿轮,轴承等零部件,相互间的配合和合理的变速比,以及合理的空间位置关系,才能使个零部件在箱体内正常安全的运行。因此这需要箱体的加工有着较高的质量,加工质量越高,会变速箱的工作效率也会相应提高,从而延长使用寿命,反之,就会影响整个变速箱的使用性能和使用寿命。
本文的研究课题主要是对于变速箱的加工工艺的研究以及总体的精镗组合机床的设计。首先,要对箱体的结构以及各个孔、面的的精度要求进行初步的了解和研究。并对此进行合理的分析,从而制定加工工艺的路线。在满足各个工序技术要求的基础上选择工序的切削刀具、切削用量以及夹具等,并确定切削的用量与时间的定额。然后再依据箱体的加工内容、零件结构特点和精度要求,确定机床配置形式,描绘出总体的机床设计“三图一卡”。最后是分析和设计组合机床以及机床的电气控制方面。
Gear-Box is an important part of loader to achieve speed change.The power from the engine to achieve transmission in the gear-box , and then spread to out location. In the box body, there are drive shafts, gear, Bearing and other parts,and cooperation reasonable speed ratio between each other,and reasonable spatial position relation,in order to make the normal and safe operation of the parts in the box body.Therefore, there is a high demand for the processing quality of the box. Relatively high processing quality,It will improve the efficiency of the gearbox,and extended service life.On the contrary,It will affect the performance and life of gear-box .
This topic is the study of gearboxes processing technology,and the overall design of precision boring combination machine.First of all, learn the basic structure of the box and the accuracy of each hole, surface.Reasonable analysis on this basis,and then develop the process route.Then according to the technical requirements of the process, the choice of cutting parameters and selection of cutting tools, fixtures, etc.Then determine the cutting quantity and time quota.Secondly, according to the structural characteristics of the processed parts, the processing content and accuracy requirements,to determine the configuration form of the machine, drawing the overall design of the machine - three charts and one card. Finally, through the combination of machine tool design, and then the electrical control part of the machine analysis and design.
