我厂生产的WH型蛙式打夯机原设计支腿与底盘连接部分见图1。使用过程中,由于打夯机使用频繁,冲击力大,用不了多久,轴1与轴架2就会严重磨损,继而轴承3也被破坏。维修时须将轴,轴架、轴承全部换掉,浪费人力物力。现在我们采用了轴与轴架锥度连接(见图2)。把轴3的一端制成1∶5锥度,另一端为M16螺纹。轴架5两 The WH-type frog-type tamping machine produced by our factory is shown in Fig. 1. During use, due to frequent use of tampers, impact force, take a long time, the shaft 1 and the shaft frame 2 will be severely worn, and then the bearing 3 is also destroyed. Repair shaft, shaft frame, bearings all replaced, a waste of manpower and resources. Now we have a taper connection between the shaft and the shaft (see Figure 2). One end of shaft 3 is made 1: 5 taper and the other end is M16 thread. Pedestal 5 two
