摘 要
减速器是机械工业中应用最多的既能够提供动力又能够减速,增加输出扭矩的装置,在各行各业的机械设备中都有用到,随着机械工业的越来越强大,各种类型的减速器将会陆续地出现在一些机械设备工厂,从而来满足不同工况的不同需求。本篇毕业设计主要是针对一级直齿圆柱齿轮减速器的介绍,对一级直齿圆柱齿轮减速器中的各个重要零件,例如传动轴,齿轮等等进行分析和设计,从而设计出参数合理,运行可靠平稳的一级直齿圆柱齿轮减速器。
关键词: 减速器、齿轮、传动轴
ABSTRACT
This paper starts from the study of the governing mechanism, combined gear box with a 11 roller straightening machine straightening the design, and structure design of the combined gear box, calculation, calculation, design and checking calculation of parameters of each gear of the transmission shaft of the transmission gear box comprises a joint. And complete the drawing and parts drawing assembly diagram, and mechanical drawing software rendering.
In the stage of structural design, should firmly establish the assurance levels of gear meshing good sense, welded body structure and the shafting structure suitable, reasonably determine the gear rotation direction and rotation direction of attention gear, lubrication piping design, to ensure that the design and calculation of implement, deceleration machine art is good, easy to use, reliable.
This topic is mainly combined speed reducer for straightening machine of design.
Key words: Straightening machine, gear box, transmission shaft
