毕业论文外文摘要
Casting technics design of planetary gear bush
Abstract
I analyze the technical conditions of the parts to clear the material composition and performance requirements of parts,analyze the casting process of the part structure to clear the structural features of parts. Secondly, According to structural characteristics of parts, technical requirements, production requirements, production volume, productions conditions I choose methods of casting and modeling. According to the structural characteristics of components, I develop a variety of pouring and parting programmes, analyze comprehensively and comparatively, choose the best pouring position and parting plan and develop a detailed programme of casting process. design feeding system and pouring system of the casting ,map out the casting process plans. Finally, I design the casting process equipment, including the templates and core-boxes and draw the assembly plans of template and core-box .
