引言回转球体是现代一些导航陀螺、伺服装置等器仪表仪常用的核心零件,它的回转精度直接影响产品的性能好坏。一般加工好的球体零件都存在不同程度的不平衡量,回转零件的不平衡量是造成回转精度降低的主要因素之一。因此,研究球体平衡,提高球体平衡精度是一个十分重要的问题。本文提出:用气体静压支撑球体进行平衡的方法,并作了一些试验工作。这一方法主法主要优点:无接触平衡,平衡精度较高。操作简单、便于定量。缺点:平衡装置加工精度要求高,不能通用。此方法也可以用于D/L>5(D——回转零件直径,L——回转零件宽度)的回转零件的静平衡。
Introduction Rotating sphere is the core part commonly used in some modern gyroscopes, servo devices and other instrumentation. Its slewing accuracy directly affects the performance of the product. Generally processed ball parts have different levels of imbalance, the amount of unbalance of rotary parts is one of the main factors that reduce the accuracy of rotation. Therefore, it is a very important issue to study the balance of the sphere and improve the balance accuracy of the sphere. In this paper, we propose a method to balance the sphere with gas static pressure and make some experimental work. The main advantages of this method of the main law: no contact with the balance, high precision balance. Simple operation, easy to quantify. Disadvantages: Balance precision machining equipment requirements, can not be universal. This method can also be used for static balance of rotary parts with D / L> 5 (D - diameter of rotary part, L - width of rotary part).
