轻型货车循环球式转向器设计
摘要
循环球式转向器是由螺母与丝杠传动副以及齿扇轴与螺母传动副二个部分组成。螺母与丝杠传动副是由里面的钢珠联系起来的，而齿扇轴与螺母传动副则是通过齿之间的啮合联系的，最终完成了力的传递。
本文首先对汽车转向器目前研究的概况和发展趋势做出了阐述说明，研究BJ2020车型汽车转向系统，整理出汽车转向系统的设计要求，然后根据汽车的类型、汽车的前后轴的负荷以及汽车的用途选择了初步的转向器类型，随后进行汽车转向器选型分析并完成总结，完成循环球式转向器各项主要参数的选择，并根据循环球式转向器的角传动比、传动效率以及使用用途并参考以往的成功车的型号对循环球式向器的强度和具体参数进行了计算，再进行循环球式转向器性能分析最后完成设计图纸以及设计说明书。最后用建模的方式画出了转向器的三维设计图，从立体的角度反映了转向器的结构功能。还有零件图，画出了循环球式转向器零件的尺寸。装配图画出了各个零件之间的配合，更全面反映了循环球式转向器的结构。受力分析则清晰的展现了循环球式转向器的各种受力情况。
设计最后完成了BJ2020转向器从结构形式的初步选择到制造工艺最后布置的所有设计，所有设计合乎标准。

ABSTRACT
Ecirculating ball type steering gear is composed of the nut and screw transmission gear and shaft and nut transmission of two parts. The nut and the screw pair is composed of a link inside the ball, and the gear shaft and nut transmission pair is linked through the meshing be- tween the final completion of the transfer of power.
Firstly, the steering situation and trend of current study to make an exposition of BJ2020 models of automobile steering system, sorting out the system design requirements for autom-
otive steering, then according to the type of car, use the car front and rear axle load and vehic- le selection of the steering type preliminary, followed by steering gear the selection and anal- ysis of the complete summary, complete the circulating ball type main parameters for the ste- ering and steering angle, gear ratio according to the circulating ball type, transmission efficie- ncy and use of reference and the model of successful car cycling ball strength and device spe- cific parameters are calculated, then the recirculating ball type steering the performance anal- ysis is finally complete the design drawings and design specification. Finally, by using the w- ay of modeling drawing to three-dimensional design, from three-dimensional angle reflects the shift The structure and function of device. And part drawing, draw the size of the recircul- ating ball type steering gear assembly drawing parts. Coordination between the various parts, more comprehensively reflect the circulating ball type steering gear structure. The stress anal- ysis show the recirculating ball steering the force.
At the end of the article, all the designs of the BJ2020 redirector from the initial selection of structural form to the final layout of the manufacturing process are completed, and the des- ign is up to standard.
Keywords:Recirculating ball steering; Process arrangement;Force analysis
