Single Tooth Roll Crusher Teeth Fatigue Research And Equal Life Optimization

Single tooth roll crusher mainly responsible for coal and rock primary crushing task, theworking environment is very bad, the broken tooth and high hardness coal and rock the relativemotion between, tooth wear and root fracture is very serious, which directly influences the singletooth roll crusher of crushing effect and stability. At the same time，frequent stop repairproduction greatly affected. Crusher work continuously， the broken tooth tooth head and coaland rock repeated contact between，fatigue failure of the machine service life plays a key role. Inthe crushing process， especially in in order to improve the efficiency， charging rate under thecondition of excessive. Make broken tooth fatigue failure of the main form of tooth wear fatiguefailure and tooth root bending fatigue failure. This topic first through the theoretical calculationto get broken tooth tooth wear and the relationship between the tooth root bending expression,again through the virtual prototype of the research,first using PROE to establish broken tooth rollentity model, and then through the ANSYS finite element analysis in the process of get brokenbroken tooth to tooth wear and tooth root bending, the relationship between the MATBALthrough with theory expression and ANSYS simulation the result that come out as a targetfunction, the broken tooth optimization and improvement, the main parameters of theoptimization for the broken tooth materials, inclination Angle, tooth, tooth length, root sectionalarea, and finally into ANSYS for fatigue analysis to verify whether the optimization is expectedto reach.
