摘 要
本文从研究矫直管机理入手,设计了一台11辊矫直机用的联合齿轮箱,并对联合齿轮箱进行结构设计,包括联合齿轮箱的传动比计算、各齿轮的参数计算、各传动轴的设计与校核计算。并完成总装图的绘制及零件图的绘制,并用机械制图软件绘制。在结构设计阶段,应牢固树立保证各级齿轮啮合良好的意识,采用适当的焊接箱体结构和轴系结构,合理确定轮齿旋向和齿轮旋转方向,重视润滑配管设计,以保证设计计算落到实处,减速机工艺性好,使用方便、可靠。
本课题主要是针对矫直机上的联合减速机进行设计。
关键词 矫直机、联合齿轮箱、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
