摘要
介绍了一种双轴平动椭圆振动筛设计时力心的确定法,分析了激振器轴的变形及其对振动筛的运动参数、抛掷指数、筛箱强度及激振器滚动轴承寿命影响。设计实践表明:力心的确定方法简单易行、准确可靠;激振器轴刚度较小时,设计中应当考虑其变形对振动筛产生的影响,特别应考虑对激振器滚动轴承寿命的影响。
This paper describes the calculation method of the vibrating force center of two-axle elliptical vibrating screen and analyzes the deformation of the exciter shaft and its influence on motion parameters, throwing cocfficient,strength of screen box, and service life of the rolling bearing of exciter.The designing practice shows that the method is simple and practical, and accurate and reliable. A consideration should be given to the influence of the shaft deformation on the vibrating screen when the rigidity of exciter shaft is smaller, specially on the service life of rolling bearing of exciter.
