小型外圆磨床的工作台手摇机构是根据下述分析对比后设计的。 一、 J4-001工作台手摇机构 这是一种外啮合行星传动机构(图1),两档变速。当中心手把2向外拉出,齿轮Z10进入转体1的内齿轮中成为一体时,工作台可实现快速运动。手轮转一转,工作台的行程为18.55 mm。 当中心手把2向内 Small cylindrical grinder table hand crank mechanism is based on the following analysis of contrast design. First, J4-001 worktable hand crank mechanism This is an external meshing planetary gear (Figure 1), two gear shift. When the center handle 2 is pulled outwards and the gear Z10 is integrated into the internal gear of the swivel 1, the worktable can realize fast movement. Handwheel rotation, work table travel is 18.55 mm. When the center hand 2 inward
