西德采煤机无链牵引传动系统的布置如图1。在图中,驱动轮是安装在行星减速器的输出轴上,而齿轨轮的轴则是固定在底托架上,圆柱销轨道则在运输机一侧沿工作面水平铺设。因为驱动轮和齿轨轮都是摆线齿形,是标准的齿形曲线之一,它们之间的传动特性无需再研究了。但普通的摆线齿轮和圆柱销齿轨的啮合怎样?它能否满足齿轮传动的基本定理?运行速度平稳么?为什么圆柱销齿轨有两种节距(125毫米和126毫米)?本文从推导齿轨轮的理论齿形出发,求证该传动装置特性的数学公式,试图对上述问题作出回答。
West Shearer chainless traction drive system layout shown in Figure 1. In the figure, the drive wheel is mounted on the output shaft of the planetary gear unit, while the pinion shaft is fixed on the bottom bracket. The cylindrical pin track is laid horizontally along the work surface on the conveyor side. Because the drive wheel and the rack and pinion are cycloidal, one of the standard tooth profiles, the transmission characteristics between them need not be studied any further. But what about the ordinary meshing of the cycloidal gear and the cylindrical pin gear? Can it meet the basic theorem of gear transmission? Is the running speed stable? Why are there two pitches (125mm and 126mm) for the cylindrical pin gear? Departure of the theoretical tooth profile of the toothed wheel and the mathematical formula to verify the characteristics of the transmission try to answer the above questions.
