文档介绍：锻锤三缸镗缸机的研制—镗轴组件设计
摘要本课题研究的是专门用于镗削加工C41-2000型空气锤的三个气门孔的专用镗床,设计对主传动系统的设计部分与镗轴的设计部分作了详细说明,对一些辅助装置也作了相应的描述。
设计从总体布局开始引出,通过认真研究、分析了设计任务书后,针对任务书的要求进行了课题调研和现场考察,提出了传动设计方案。确定电动机的功率,分析各种传动下的主轴的转速,转矩以及所消耗的功率。确定传动过程和传动装置,选择合理的齿轮传动,选择了齿轮的齿数及齿宽,最后对齿轮的齿数和模数的校核。在主轴的设计中,初选结构参数,确定组件的布局,然后在已确定主轴结构尺寸的基础上,进行主轴的强度和刚度的校核。正确选择轴承,并对轴承进行校核验算。
本文将重点叙述主变速传动设计部分和镗轴的设计部分。主变速系统设计进行中,这些部分将以工作缸镗轴变速箱输入轴为主要设计和校验对象,在此基础上尽量扩大轴的尺寸,以满足其它各轴的设计要求,轴径大小与长度的选择、轴的轴向定位、周向定位、轴的强度校核为本章的主要内容。镗轴设计中,以镗轴的组件的设计为重点,以镗轴的悬伸量选择,跨度计算和刚度的计算展开,并对镗轴的性能和基本要求等做了粗略介绍。

Forging hammer three-cylinder boring lathe development
—boring axis module design
Abstract What this topic research is uses in processing the C41-2000 air hammer pneumatic hammer's three valve port special-purpose boring lathes boring specially, designed has given the detailed explanation to the master drive system's design part and the boring axis design part, has also made the corresponding description on some auxiliary units.
The design starts from the entire distribution to draw out, after studies, has analyzed the design project description earnestly, in view of the project description request has carried on the topic investigation and study and the scene inspection, proposed the transmission design proposal. The definite electric motor's power, analyzes under each transmission main axle's rotational speed, the power which the torque as well as consumes. The definite transmission process and the transmission device, choose the reasonable gear drive, has chosen gear's number of teeth and the tooth width, finally counter gear's number of teeth and modulus examination. In main axle's design, primary election design parameter, definite module's layout, then, determined that the main axle structure size in the foundation, carries on main axle's intensity and the rigidity examination. Chooses the bearing correctly, and carries on the examination checking calculation to the bearing.
This article will narrate the main variable transmis
