地质钻机的卷筒广泛采用行星机构传动。这是一种比较成熟的结构,但还应进一步改进,以提高卷筒寿命,改善传动质量。一、问题的提出钻机卷筒传统结构如图1。卷筒受载后行星机构啮合状态如何,将直接影响传动质量。图2表示了受载后的卷筒主轴的变形及齿轮啮合情况。假定:
Geological rig reel widespread use of planetary gear. This is a more mature structure, but should be further improved to improve reel life and improve transmission quality. First, the question raised Drill drum traditional structure shown in Figure 1. After the reel is loaded, the meshing state of the planetary mechanism will directly affect the transmission quality. Figure 2 shows the deformation of the mandrel after loading and gear engagement. assumed:
