“双体式”万向联轴器的设计与应用
Design and Application of “Two-Body” Universal Coupling

为提高GDX2000、GDX500型包装机中存在的透明纸美容器需要维修、油箱漏油等需要将双联轴器脱开才能修理的修理效率，并降低因拆装联轴器的操作难度和劳动强度，避免因拆装联轴器而移动设备存在的安全隐患，本次研究针对卷烟包装机的双万向联轴器进行设计改进。该装置为左右两个联轴器通过联轴器中轴及两个定位销、锁紧螺栓连接成一个双万向联轴器。该联轴器一端连接小盒透明纸包装机的动力输出轴，另一端连接CT条盒包装机动力输入轴。以GDX500包装机为例，所述双体式万向联轴器在拆卸中仅需要拆除中轴后，即可将左万向联轴器、右万向联轴器在不需要整体移动CT条盒包装机的情况下拆除。
In order to improve the repair efficiency of the transparent paper beauty device in the GDX2000 and GDX500 packaging machines that needs to be repaired, the oil tank leaks, etc., the double coupling can only be repaired by disengaging it, and reduce the difficulty and labor intensity of the operation due to the disassembly and assembly of the coupling, to avoid the potential safety hazard of moving the equipment due to the disassembly and assembly of the coupling. This research is aimed at improving the design of the double universal coupling of the cigarette packaging machine. In the device, the left and right couplings are connected to form a double universal coupling through the coupling center shaft, two positioning pins and locking bolts. One end of the coupling is connected to the power output shaft of the small box transparent paper packaging machine, and the other end is connected to the power input shaft of the CT box packaging machine. Taking the GDX500 packaging machine as an example, the double-body universal coupling only needs to remove the central shaft during disassembly, and then the left and right universal couplings can be assembled without moving the CT box as a whole. Remove the case of the packaging machine.
