在工程机械中广泛应用着各种类型的摩擦离合器。如一台单原动机驅动的单斗挖掘机,就有大小离合器6～8个。实践証明,摩擦离合器对整个机器的性能和可靠性有着直接的影响。摩擦离合器在运轉接合过程中,由于主动与从动部分之間有相对滑动,由摩擦功轉变成的热量,使离合器的温度升高。如果温度超过一定的限度,会使摩擦系数降低,离合器所能传递的扭矩发生波动,并将加速摩擦衬的磨损。严重时甚至使摩擦衬燃烧(冒烟),从而使整个离合器失去效用。因此,要設計一个完善的摩擦离合器,就必須进行离合器的溫升計算。本文从叙述离合器的接合过程开始,討論摩擦离合器的温升計算方法。这些方法,在原則上也适用于摩擦制动器的温升計算。
In construction machinery widely used in various types of friction clutch. If a single prime mover driven single bucket excavator, there are 6 to 8 size clutch. Practice has proved that the friction clutch on the performance and reliability of the machine has a direct impact. Friction clutch in the operation of the bonding process, due to the relative movement between the active and driven parts, the frictional heat into the clutch, so that the temperature rise. If the temperature exceeds a certain limit, the friction coefficient will be reduced, the clutch can transfer torque fluctuations, and will accelerate the friction lining wear. Even in severe cases friction lining burn (smoke), so that the entire clutch lost its effectiveness. Therefore, to design a perfect friction clutch, it is necessary to calculate the temperature rise of the clutch. This article starts with the description of clutch engagement process and discusses the calculation method of temperature rise of friction clutch. These methods, in principle, also apply to the calculation of the temperature rise of friction brakes.
