Title The Three-dimensional Design Of High-speed Rotating Experimental Platform

Abstract

A high-speed rotating experimental platform is used to implement the relative motion inside high-speed  rotating parts , simulate its real motion . The high-speed rotating consists of two structures: the base and the head, and the two parts have relative rotation. wherein the head part is rotated by a low-speed motor, the base part is rotated by a high-speed motor. Entire experimental platform mainly consists of low-speed motor, high-speed motor,low-speed transmission,high-speed transmission, the experimental platform, the base .

Based on what I have learned and access the relevant information, Combined with the existing experimental platform body,the above  structure of the main components of the high-speed rotation experiment platform are designed , the chosen of the motor, shaft component design, gear selection ,and the installation and fixation of the experimental platform .some problems should be considered in the high-speed rotation experimental platform are analyzed,solutions are proposed,and the relevant two-dimensional and three-dimensional pictures are drew.
