摘要
工业风扇及同类型超薄转子(转子直径D与厚度H的比在8～16倍)一般为悬臂安装,其剩余不平衡量严重影响系统的振动和噪声大小,以及运转的平稳性。现有的动不平衡检测装置不能满足该类转子的平衡工艺技术要求,必须寻求一种新的方法和装置,使静不平衡与偶不平衡分离,进而达到动不平衡检测及校正的目的。本文根据该类转子的特点,运用平扭复合杆、弯摆复合杆、空心悬臂安装传感器等建立的振动模型,研究开发出了高分离比静、偶动不平衡检测装置及动平衡机。
The installation of industrial fan and the same type of ultrathin rotor, whose diameter D is 8--16 times more than its thickness, is commonly cantilever mounting. Their residual unbal- ance seriously influences the vibration, noise and stability of the whole system. The existing dy- namic unbalance detection equipment couldn＇t satisfy the balancing technical requirements of the rotor described before. It is necessary to find a new way to separate static unbalance and couple unbalance so that dynamic unbalance can be monitored and corrected. This paper establishes vi- bration model based on the property of the rotor as before. Also, a new static-couple dynamic un- balance detection equipment and dynamic balancing machine of high separation ratio is developed.
