一、在万工显上测量齿轮R值首先将齿轮安装在<1∶50000的锥度心轴或无锥度的光滑心轴上(心轴的径向跳动不得大于0.003mm),然后将其顶在万工显两顶尖间(图1)。把测量刀架放在纵向滑台的丁字槽内,并安装一把高度为5毫米的测量刀,拼研从纵向滑台表面到测量刀上表面高度的量块。此高度就是其顶尖联线的中心高(图2)。在物 First, the measured value of all workers in the gear R value First gear installed in the <1: 50000 taper mandrel or taperless smooth mandrel (mandrel radial runout shall not be greater than 0.003mm), and then top Million workers showed two top (Figure 1). Put the measuring tool holder in the T-slot of the longitudinal slide and install a measuring knife with a height of 5 mm to work out the measuring block from the surface of the longitudinal slide to the height of the upper surface of the measuring knife. This height is the center of the top line (Figure 2). In the matter
