摘要
对2YAC2460超重型振动筛进行虚拟设计,进行运动学动力学模拟与仿真,研制了可摆动电机座,解决了振动筛在启动和停机发生共振时大幅度的摆动损坏电机座的问题,延长了皮带和电机座的寿命;对2YAC2460超重型振动筛筛框进行有限元分析,设计了一种振动筛筛架型材联接方法,用法兰盘与筛框和侧板连接,解决了原整体筛框焊接应力大、易产生裂纹问题,延长了筛框及整机使用寿命。
Virtual design of the ultra-heavy vibrating screen 2YAC2460 is completed, with kinematical simulation and dynamics analysis done as well. Oscillating motor set is innovatively developed, which could avoid damaging the motor set when the machine starts or stops and thus prolongs the service life of belt and motor set. Finite element analysis of screen frame of the ultra-heavy vibrating screen 2YAC2460 is done. A kind of connecting mode of vibrating screen frame is innovatively developed, which uses flange to connect the screen box and side plates, and the problems of cracks in screen box caused by the great welding stress is solved. Both the service life of the whole machine and the screen box are prolonged accordingly.
