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。
Aiming at the difference of the working mechanism and the installation position of the brake of the traditional traction elevator, combining with the characteristics of the hydraulic brake and the electric disc brake, the article presents a follow-up linear brake structure suitable for the direct-drive elevator, The E-type electromagnetic drive mechanism is a brake driving source and amplifies the force by a force increasing mechanism. A finite element model of the driving mechanism is established. The magnetic circuit method is used to analyze the characteristics of the magnetic drive mechanism and the electromagnetic attraction force of the brake driving mechanism. Optimize the structural parameters of the drive mechanism. The results show that the optimized electromagnetism attraction force of the driving mechanism is obviously improved, which is of certain reference value to the research of electromagnetic brake of direct drive elevator.
