【摘要】：针对传统曳引式电梯的工作机理及制动器安装位置的不同,结合液压制动器和车用电磁盘式制动器的特点,文章提出了一种适用于直驱电梯的随动直线式制动器结构,以新型双E型电磁驱动机构为制动器驱动源并通过增力机构将力放大;建立了驱动机构的有限元模型,采用磁路法分析制动器驱动机构的磁密和电磁吸力等特性,并利用有限元的方法对驱动机构的结构参数进行优化。结果表明,优化后驱动机构的电磁吸力得到显著提高,对直驱电梯电磁制动器的研究具有一定的参考价值。
[Abstract]:In view of the working mechanism of traditional traction elevator and the different installation position of brake, combined with the characteristics of hydraulic brake and electromagnetic disc brake, this paper puts forward a kind of servo linear brake structure suitable for direct-drive elevator. The new double E electromagnetic drive mechanism is used as the brake driver source and the force is amplified by the force increasing mechanism, the finite element model of the drive mechanism is established, and the magnetic density and electromagnetic suction characteristics of the brake drive mechanism are analyzed by the magnetic circuit method. The structural parameters of the drive mechanism are optimized by finite element method. The results show that the electromagnetic suction of the drive mechanism is greatly improved after the optimization, which has a certain reference value for the study of direct-drive elevator electromagnetic brake.
