ZXD4273香蕉筛振动筛的设计.doc

摘 要 本文主要是针对双轴等厚振动筛的设计进行的，从整体布局到个别零件的选用都进行了改良，包括筛箱，筛面的设计和固定，激振器的形状，支撑方案的设计等等，还包括轴，齿轮，带轮，偏心块等零件的设计。采用单电机带动，齿轮传动来使得两个偏心块同步，另一方面采用用了座式结构，淘汰了以往悬挂式的方式，使得结构更加安全，占地面积更小。 本产品为生产能力为640t/h 的大型振动筛，对于筛框的材料有比较高的要求，现采用高强度和高冲击韧性的钢材，不仅仅提高了筛框的耐用度，还减轻了整个结构的重量，对弹簧的选择等许多方面也带来了很多的方便。 设计中还包括对连接和固定件的选用，采用耐用的十字轴联轴器，并用螺栓和铆钉连接代替焊接，减小了焊接时应力对它的影响。还包括对产品的润滑，以及保养等日常维护措施。 关键词： 振动筛 激振器 偏心块 横梁 Abstract This article is carried out mainly according to the design of the two axle banana linear vibrating screen, from overall layout go to individual element choose to go on improving , include sifting the design of case and compass screen surface and the regular shape of vibrator , support the design of scheme and so on , still include the design of the elements such as axle, gear, belt and partial piece. Drive with single generator, positive drive makes two partial pieces synchronous, has adopted on the other hand to use type structure, have superseded the way of former overhead suspension, make structure more safe, it is less to cover an area of area. This design product has higher requirement, for the material of screen frame for productivity is the large scale vibrating separator of 640 t/h, has now not only raised the durability of screen frame with the high-strength and high steel material of impact tenacity, have still alleviated the weight of entire structure, for spring choose to have also brought many conveniences. In design still include for connection and regular choosing, with the durable shaft coupling of cross axle, replace welding with bolt connection, it is little to reduce welding stress for its influence. In this design, include the lubrication for product as well as the daily maintenance measures such as maintenance.
