曳引机盘式制动器优化设计

Optimization Design of Disc Brake Used for Traction Machine

针对电梯曳引机盘式制动器各功能性元件构型不合理,以及微动开关机构稳定性差等问题,研究了盘式制动器和微动开关的结构和工作原理,设计了一种新型盘式制动器,该制动器构型合理,性能优良。通过实验,对比现有结构和优化结构,结果表明,新型制动器制动响应时间更短,微动开关稳定性更好,使用寿命长。

For the unreasonable configuration of functional parts of disc brake and the poor stability of microswitch mechanism occurred in traction machine of electric elevator,the structures and working principles of disc brake and microswitch had been studied,and a new type of disc brake with reasonable configuration and excellent performance had been designed.Through experimental comparison between the traditional and optimal structures,the results show that the new type of disc brake has the advantages of shorter braking response time,better microswitch stability and longer service life.
