文档介绍：摘要
选煤厂的筛分机数量很多,所以对筛分机的要求也越来越高。不但要求它具有较高的生产率、较好的筛分效率或脱水效果、较低的动力消耗;而且还要具备结构简单、制造容易、安装维修方便等机械性能。由于滚轴筛、圆筒筛上述性能较差,在使用上受到了限制,逐渐被工艺效果好、构造简单、维修方便的振动筛所代替。
自同步振动筛是一种广泛用于散体物料分级的设备。在选煤等工业领域,用于分级、脱水、脱泥和脱介。其筛分性能尤其重要。
本文系统地阐述了双电机自同步振动筛的应用现状和发展趋势,论述了设计高效双电机自同步振动筛的必要性;同时对双电机自同步振动筛的原理进行了分析,计算了振动筛的动力学参数、运动学参数,设计计算了激振器的轴、偏振块的参数和结构,减震装置,筛框的设计,并进行联轴器的选型等。
关键词:双电机;自同步振动筛;激振器
Abstract
The large number of Washery screening machine. so the demands on the screening machine also getting higher and higher. It is not only demand higher productivity. better screening efficiency or effectiveness dehydration. low power consumption. but also with simple structure. easy to manufacture. installation and maintenance convenient mechanical properties. As roller sieve. sieve cylinder of the poor. by the use of restrictions have been gradually effect of good. simple structure and easy maintenance replaced by the shaker.
In this paper. systematically expounded the two-synchronous motor shaker since the application status and trends on the design of highly efficient dual-synchronous motor shaker since the necessity of the dual-motor while simultaneously shaker since the principle of the analysis. calculate the shaker The parameters. parameters of kinematics. design and calculation of the axis of the exciter. the parameters and polarization block structure. damping device. the screen box design and coupling the selection.
Key words:double motor;self-synchronous motor;shaker vibrator
