摘要
由于磁粉离合器处于滑差工作状态时,产生大量摩擦热,从而使它的应用受其散热功率的限制。因此,提高散热功率是研究磁粉离合器(制动器)的关键。本文从磁粉离合器损失功率出发,通过四种运行方式进行热力学讨论,并用数学关系式论证了其温升与各变量的关系。亦提出了增大散热功率的几种设计方法及选用原则。最后通过实例进行了验证。
The use of the magnetic particle clutch is limited by its heat dissipated power as a quantity of friction heat is generated when it is in the slip operating mode. So, one of the key problems in the research of the magnetic particle clutch is to increase its heat dissipated power. In the article, the thermodynamics in four operating modes is discussed proceeded from the wasted power of the magnetic particle clutch, the relation between the temperature rise and various variables is demonstrated by the mathematical formulation, several design procedures and their selective principle of increasing heat dissipating power are put forward, and, at last, they are verified by the examples.
