| Abstract: | In view of the problem in the design of the present new-style star wheel loading mechanism, this article has confirmed the relationship between rotating speed and parameters of star wheel structure and the lowest rotating speed of it under the circumstance of unjamming according to the movement characteristics of the star wheel loading mechanism and the operating performance of the road-header as well as the mechanics analysis of the star wheel loading mechanism. This article has also worked out the critical rotating speed of the star wheel according to examples so that it provides the theoretical basis for the research and design of the star wheel loading mechanism. |
