文档介绍：哈尔滨理工大学学士学位论文-I- 塑料挤出机 CAD 摘要本文旨在研究塑料挤出机的结构形式,及工作原理。挤出成型在塑料制品成型加工工业中占有很重要的地位。据统计,在塑料制品成型加工中, 挤出成型制品的产量居首位。因此,塑料挤出成型机械无论是现在还是将来,都是塑料加工行业中得到广泛应用的机种之一。本设计通过对塑料挤出机结构的了解,从而熟悉它的工作原理,经过推敲,选择合理传动系统总体布置形式,螺杆,机筒,减速器选择及轴承布置形式等,分离型螺杆与摆线针轮减速器的选用是本文要点,本文主要参考 JB/T8061-96 《单螺杆塑料挤出机》进行选择螺杆及机筒材料,公差,装配精度及冷却等方面进行选择与较核,并逐步确定一些设备及零部件的型号及尺寸等参数,画出实验装置的原理图、装配图,并进行必要的校核,并最终确定零部件的型号及尺寸等参数。本说明书可以进一步加深读者对本装置的理解和认识。同时本装置具有结构相对紧凑、性能可靠、价格相对便宜、完全具有自主知识产权的特点,因此非常适合大中小型塑料加工成型的厂家生产或购买。关键词轴承布置;分离型螺杆;摆线针轮减速器哈尔滨理工大学学士学位论文- II- single-screw plastic extruder CAD Abstract This article aims to study the structure of plastic extruder frame form, and working principle. Extrusion molding in plastic products processing industry occupies an important position. According to statistics, in the molding of plastic products processing, extrusion products output ranked first . Therefore, plastic extrusion molding machinery either now or in the future, plastic processing industry is widely applied in the model. T hrough the design of plastic extruder understanding of the structure, thus familiar with its working principles, passes through deliberates carefully, a reasonable choice of the overall layout and Transmission System , Screw, barrel, bearing reducer selection and layout form, separation of screw-cycloid reducer and the main points of this article is optional, Also, the mechanical inertia and relevant parameter is calculated according to JB/T8061-96 《S ingle S crew Extruder 》 choice of screw and barrel, tolerance, the assembly of precision and cooling, and other aspects of the nuclear option and more, t hen the assembling drawing pleted, and the necessary checking is also finished, so the partial mode number and size parameter is ultimately found. The specification can deepen prehension of readers about the testing set. The device is characterized pact structure, reliability, low cost, and independent intellectual property. This is rather appropriate for the Plastic molding factory processing of small scale and
