带式输送机高速托辊的应用研究

Study on application of high-speed idlers of conveyors

通过对带式输送机及托辊的应用现状进行分析,提出了研发带式输送机高速托辊的必要性。通过对托辊主轴、轴承、筒体、密封结构和轴承座等各部分结构进行研究,探讨了高速托辊在径向圆跳动、旋转阻力和使用寿命等方面要解决的关键技术,为高速托辊以及高速带式输送机的设计应用提供理论基础。

After analyzing the application status of the belt conveyor and the idler, the necessity of developing high-speed idlers is proposed. Based on the study of such components as idler shaft, bearing, sealings and bearing pedestal, such key issues of high-speed idlers as radial run-out, rotary resistance and employment lifespan are discussed, which offers theoretical basis for the design and application of the high-speed idler and the high-speed belt conveyor.
