缠绕式垫片专用缠绕机的设计(含CAD图)(论文说明书12000字,CAD图12张)
摘 要
缠绕垫片属于金属与非金属材料复合平垫片,是用于机械密封的垫片之一,在炼油、化工、动力和原子能等工业部门得到广泛应用。引进的大型石油化工装备中,许多化工设备都使用缠绕式垫片,且规格、品种和形式众多。本文设计研制一台缠绕垫片专用缠绕机,能够生产DN80~DN400的缠绕式垫片,垫片尺寸可预置、绕制工艺参数(钢带的压紧力和拉紧力)可控、可调,自动化程度高、操作弹性大、调节性能好、操作简单、可靠。首先对缠绕机整体结构进行分析,其次对各个部分零件的设计进行详细计算。主要部分由电机带动皮带轮传动到齿轮箱,通过一个齿轮蜗杆减速器,减速器主轴突出,用于安装中心轮;机架部分通过一个恒定的气压使之上下运动,从而达到压紧的作用。由主机,进给系统、气源及控制系统组成,各个部分环环相扣,对零件的选择在精度,强度和耐磨性等方面都有很高的要求。本次设计的重点是工艺的可操作性和实用性,根据设计图纸的要求合理安排。

ABSTRACT
Spiral wound gasket belongs to metal and non-metallic materials flat composite gasket,it is one of the gasket is used for mechanical seal, in oil refining, chemical, power and nuclear power industries widely used. Introduction of large petrochemical equipment, many chemical equipment using spiral wound gasket, and many specifications, varieties and forms. This paper designed a special winding gasket winding machine, able to produce DN80~DN400 winding gasket.,gasket size can be preset, winding process parameters (compression force and tension force of the strip) controllable and adjustable, high automation, large elasticity of operation, good regulation performance, simple operation, and reliable. First of all to the winding machine overall structure are analyzed, next to the design of all parts in detail calculation. Main part driven by the motor pulley drive to the gearbox, through a gear reducer, reduction gear main shaft is used to install the center wheel; chassis parts through a constant air pressure to make it up and down, So that reach the role of compression.this winding gasket is made by the host, feeding system, air supply and control system, each part of the piece, the selection of parts in accuracy, strength and wear resistance, etc, have very high requirements. This design is the focus of the operability and practicability of the process, reasonable arrangement according to the requirements of design drawings. [资料来源:http://doc163.com]
