Research On Material Removal Strategy Of Auto Dynamic Balancing Machine

With the rapid development of modern industry, the status of electromotor industry is becoming more and more important. The demand of quantity and quality of motor becomes higher and higher. And to limit the liberation of electromotor, dynamic balancing is very necessary .So to develop auto balance equipments in order to improve the efficiency and precision of balance turns into a new emphasis of dynamic balance field. On the basis of abundant research on technology and products about dynamic balance, we develop a hard bearing ,rigid rotor auto dynamic balancing machine for miniature electromotor rotor. At the same time, some key problems about material removal system design are discussed in the paper. The main contents are included as following:Briefly introduces the principle and sense of dynamic balance theory and the developing conditions of dynamic balancing machine at home and abroad. According to the question that more research about present auto balance machine is focused on the precision increasing of measure part than material removal part such as the model establishing and tool choosing, the meaning and content of this thesis are raised.Detailedly studies the principle of unbalance measure, the relationship between amplitude, phase and unbalance, fixed coordinate component, balance precision and the demands for remaining unbalance. The content above is the theoretic foundation of material removal part design and error decrease.On the basis of the analyses of unbalance correction method and the generated cause and resolvent of correction error, a material removal strategy for our machine by mill is chosen. Furthermore, we modify correction mass model, theoretically eliminating radial error and avoiding the randomicity of axial error. In view of many factors such as balance precision, work efficiency, describe how to chose the parameters of tool and calculate the corresponding cutting force and power.Some details about material removal system design are introduced includingdesign idea, design rule, overall arrangement, flowhsheet and the design details of subsections. Then the algorithm of material removal is introduced in pseudo code and the infection of rotor parameter and unbalance variable on parameter selection is summarized.
