摘要：我国的振动筛在运行和维修方面中存在着大量的问题。这些问题突出表现在筛箱断梁、裂帮原煤分级筛
,稀油润滑的箱式振动器漏油、齿轮打齿、轴承温升过高、噪声大等问题,同时伴有传动带跳带断带等故障。这类问题直接影响了振动筛的使用寿命,严重影响了生产。本文针对这些问题特设计了ZKB3660型直线振动筛，这类振动筛可以很好的解决此类问题，该系列振动筛是工矿企业普遍应用的筛分机械，用作物料的筛分、分级、洗涤、脱介、脱水之用。根据的是自同步原理，采用的是双电机直接驱动，代替强制同步式的齿轮传动，振动轨迹为直线。克服了以往振动筛由于单电机拖动，齿轮强迫传动引起的齿轮润滑，封闭问题，从而提高了整个振动筛的使用寿命。设计分析论述了设计方案，包括振动筛的分类与特点，对物料的运动分析，对振动筛的动力学分析及动力学参数计算，包括原始的设计参数，电机的设计与校核；进行了主要零部件的设计与计算，弹簧的设计计算，轴的强度计算，轴承的选择与计算，然后进行设备维修、安装的设计。最后进行了振动筛的的环保以及经济分析。 关键词： 直线振动筛； 块偏心式 ； 弹簧 ；电动机
Abstract
China since reform and opening, vibrating screen industry have seen significant development. In particular, the 21st century, exists in all walks of life in the shaker. However, vibrating screen career started late in China, rapid development, therefore, in the vibrating screen operation and maintenance, there are many problems. These problems highlight the performance of the sieve box off beam, crack help, dilute oil lubrication in the box vibrator oil spills, fight gear teeth, bearing temperature rise too high, noise, etc, and accompanied with a jump drive with a belt and other faults. These problems directly affect the life of a shaker, has seriously affected production. ZKB3660 linear vibrating screen can solve such problems, the series of vibrating screen is widely used in screening industrial and mining machinery, used as the material of the screening, grading, washing, using the two-motor direct drive, instead of mandatory synchronous gear drive, vibration track a straight line. Overcome in the past as a single shaker motor drag, caused by the gear drive gear forced lubrication, closed questions, thereby increasing the life of the shaker. Design and Analysis discusses the design, including the classification and characteristics of vibrating screen, the movement of materials analysis,
Dynamic analysis of shaker and kinetic parameters, including both the original design parameters, motor design and verification; for a major Parts of the design and calculation of spring design and calculation, shaft strength calculation, bearing selection and calculation, and then proceed to equipment maintenance, installation design. Finally, a vibrating screen of the environmental and economic analysis.
