《DB》双频供电机组有两种工作状态,当用油机驱动发电机时,需要将油机的主轴与电机轴联接起来,以便驱动发电机转动,如有市电供应时,则不需开动油机,由市电(工频)直接驱动电机发电,此时电机轴应与油机主辅脱开,为了实现油机主轴与电机轴既能自动结合又能自动脱开的机械联接,特采用单向自动离合器。这种机构和其他类型的离合器比较有以下优点:体积小,操作方便,工作可靠。在本文中,介绍单向自动离合器的工作原理,分析离合器在各种工作状态下的受力情况,以及传动力矩,传动功率的计算方法等。
“DB” dual-frequency power supply unit has two working states, when the oil machine to drive the generator, the need to oil the spindle and the motor shaft connected to drive the generator rotation, if the supply of electricity, you do not need Start the oil machine, the mains (power frequency) directly drives the motor to generate electricity. At this moment, the motor shaft should be separated from the main and auxiliary of the oil machine. In order to realize the mechanical connection that the oil machine main shaft and the motor shaft can both automatically and automatically disengage, Special use of one-way automatic clutch. This mechanism and other types of clutch has the following advantages: small size, easy operation, reliable work. In this paper, the working principle of one-way automatic clutch is introduced, the force condition of the clutch under various working conditions is analyzed, and the calculation method of transmission torque and transmission power are also analyzed.
