Finite element analysis of the gear bearing body（Low speed shaft, planet carrier）

Abstract Now in the process of economic development, each country of the underground coal mining to the development direction of the comprehensive mechanized coal mining equipment。 Coal mining mechanical gear support (low speed shaft and the planet carrier) research has great significance。 This design using 3D software (SolidWorks) planetary frame and the establishment of a three-dimensional model of the low speed shaft, at the same time, the three-dimensional model is imported into ANSYS to establish the finite element model, stress obtained by finite element analysis of force and deformation cloud cloud, and the latter can be optimized, inspection plan。 Finally, modal analysis, loading and solution model。 Modeling in modal analysis similar neutralizes the static analysis process, Choose appropriate modal extraction method, of planetary gear and shaft applied displacement constraints, multiple expansion set solving。 Through modal analysis, find out the frequency and gives some corresponding conclusions。 The correct selection of the structure size of the planetary gear and shaft and can improve the accuracy of the work, working stiffness and wear resistance; reduce the quality of equipment, metal material saving。 Finally, in light of the suitable materials for manufacturing, which for mechanical production and has great reference value。

There are 44 figures, 5 tables and 15 references in this paper。
