起重机回转减速机制动器设计研究

Study on Brake Design for Crane Rotary Reducer

以起重机回转减速机制动器为对象,首先阐述了制动器的结构类型及制动原理,并根据回转减速机制动扭矩、制动器开启压力范围等参数,计算出了制动器摩擦片尺寸参数、制动弹簧参数、制动行程、活塞面积等。经现场调试及校核验证,制动器参数设计合理,能满足减速机制动要求。

Take the crane rotary speed reducer as the object,firstly,the structure type and braking principle of brake are introduced. Based on the parameters of the torque and brake opening pressure range, the parameters of brake disc size, brake spring parameters, braking stroke and piston area are calculated. After re can meet the speed peated commissioning and verification, the brake parameter design is reasonable and reduction mechanism.
