摘　　要：立式离心机是运用高速旋转离心原理实现固液分离的装置,本文按照设计要求设计了一套含制动装置、转鼓、转盘、主轴、电机、带传动装置、轴承等零部件的离心机装置。按照制动行程为17 mm左右、制动时间为12 s的设计要求,设计了含弹簧箱的柔性制动装置,并对弹簧箱中的碟形弹簧进行选择和计算。对所设计制动装置分别施加5,10,15,17.5 mm 4种制动行程后,进行离心机制动仿真。仿真结果表明,制动行程为17.5 mm时,可以保障离心机在12 s内停机。所设计立式离心机及制动装置能够满足各项设计要求。Vertical centrifuge is a device that uses high-speed rotary centrifuge to achieve solid-liquid separation.A set of centrifuge device including brake device,drum,turntable,spindle,motor,belt drive and bearings is designed.According to the design requirements of braking stroke of about 17 mm and braking time of 12 s,a flexible braking device with a spring box was designed,and the disc springs in the spring box were selected and calculated.After the four brake strokes of 5 mm,10 mm,15 mm and 17.5 mm were respectively applied to the designed braking device,the centrifuge brake was simulated.The simulation results show that when the braking stroke was 17.5 mm,the centrifuge could be stopped within 12 s.The designed vertical centrifuge and braking device can meet all design requirements.
