# 小型便携清雪机主轴设计Design of the Spindle of a Small Portable Snow Cleaning Machine

Abstract: Based on the requirements of snow clearance in cold regions such as northeast region in China, a new type of small portable snow blower is developed. Spindle is the key part of snow cleaning machine, and its strength and stiffness directly affect the working of the main machine. In this pa-per, the main parameters of the spindle are determined according to the requirements of the work of the snow cleaning machine and the design theory of the shaft. Then the three-dimensional model of the spindle is established by using PRO/Engineer. Finally, the static analysis and modal analysis of the spindle are carried out with ANSYS.
