针对目前国内机械压力机摩擦离合器制动器工作能力极限评价指标所存在的缺陷,通过深入分析导致摩擦材料失效的主要因素,认为采用摩擦极限功和摩擦极限功率即功能许用极限作为评价摩擦离合器制动器工作能力极限指标更为合理,并且推导建立了摩擦离合器制动器工作中摩擦功与摩擦功率的计算公式,建立了评价摩擦离合器制动器工作能力极限的新方法,实验证明,新方法是正确的。
Aiming at the shortcomings of the ultimate evaluation index of the working ability of the friction clutch brakes in domestic mechanical press, the friction limit work and the friction limit power, which is the function allowable limit, are considered as the evaluation of the friction clutch brake work through in-depth analysis of the main factors leading to the failure of the friction material. The ability limit index is more reasonable, and the calculation formula of frictional power and frictional power in frictional clutch brake work is deduced. A new method to evaluate the working ability of frictional clutch brake is established. The experiment proves that the new method is correct.
