椭圆振动筛的设计(含CAD零件图装配图)(论文说明书20000字,CAD图6张)
摘  要
椭圆振动筛是矿业生产中广泛使用的机械之一，它是进行矿物筛选的关键设备，自19世纪第一台椭圆筛选及问世以来，椭圆振动筛就一直被广泛的应用于矿业中。因此，无论是设计阶段对椭圆振动筛的选择还是矿山企业在生产阶段对椭圆振动筛的管理都十分重视。同时许多椭圆振动筛的设计研究单位和生产厂家也对椭圆振动筛进行了很多研究工作，取得了很大进展，出现了多方面的研究方向。     
最近几年，椭圆振动筛在外部系统方面取得的较为突出的成果。主要有减速传动装置的发展。原有的边缘传动出现了结构更加紧凑的紧密传动方式。
因为传动的工作性能直接影响着椭圆振动筛的性能和成本，有的甚至起决定性作用，传动装置在整个椭圆振动筛中占有十分重要的地位，所有本次设计主要以TDLS 3090 椭圆振动筛设计为基础。对椭圆振动筛各基本参数计算，电机的选择及计算,弹簧的设计及校核，振动器轴的设计，轴承计算选择，对带传动系统设计。对椭圆等厚冷矿振动筛进行评价与比较，确定合理的设计方案。

ABSTRACT
The elliptical vibrating screen is one of the widely used machinery in mining production, and it is a key equipment for mineral screening. Since the first elliptical screening machine was introduced in the 19th century, the elliptical vibrating screen has been widely used in mining. Therefore, both the selection of elliptical vibrating screens during the design phase and the management of elliptical vibrating screens by mining enterprises during the production phase are highly valued. At the same time, many design and research units and manufacturers of elliptical vibrating screens have also conducted a lot of research work on elliptical vibrating screens, and have made great progress, resulting in various research directions.
In recent years, elliptical vibrating screens have achieved outstanding results in external systems. The main development is the reduction transmission device. The original edge drive has introduced a more compact compact compact transmission method.
Because the working performance of the transmission directly affects the performance and cost of the elliptical vibrating screen, and some even play a decisive role, the transmission device plays a very important role in the entire elliptical vibrating screen. All of this design is mainly based on the TDLS 3090 elliptical vibrating screen design. Calculation of basic parameters of elliptical vibrating screen, selection and calculation of motor, design and verification of spring, design of vibrator shaft, selection of bearing calculation, and design of belt transmission system. Evaluate and compare the elliptical and equal thickness cold ore vibrating screen to determine a reasonable design plan.
Keywords: elliptical vibrating screen, design, verification
