[Abstract]:Long arm centrifuge is an important equipment to test the performance of key parts under centrifugal field. The movable leveling system is used to realize the automatic and accurate balancing of centrifuge and to reduce the unbalanced force produced in the process of operation. It is the key component to ensure the normal and reliable operation of the centrifuge. According to the working condition of the centrifuge, a movable leveling system is designed, which is composed of motor, synchronous belt, gear, wire rod and nut, guide rail slider and force sensor. The working mechanism of the system is expounded, the design parameters of the main parts are determined, and the mechanical analysis of the key parts is carried out. The results show that the movable leveling system can effectively improve the working conditions of the centrifuge and meet the requirements of the leveling.
