Abstract: Abstract: the article to SSC1150 sizing crusher deceleration pause as the background, in view of the finite element analysis software for complex geometry structure, cannot be comprehensive and accurate to the disadvantages of its load of modeling, through one-way combination of discrete element and finite element method, based on maximum stress index, on the strength of the tooth roll under different nominal transmission ratio is analyzed and compared. The results show that under the same strength load, the position and value of the maximum stress on the tooth roller are different when the nominal transmission ratio is different. At the same time, it can be seen from the cloud chart of maximum stress suffered by the toothed roller that the maximum stress value suffered by the toothed roller can be effectively reduced if the nominal transmission ratio of SSC1150 sizing crusher is 20 in the selection.
