瑞士Fássle rAG 公司专事齿轮珩磨精加工,该公司采用了一种独特的珩齿方法珩磨普通正齿轮和外螺旋齿轮,珩磨头实际上是一个大的内齿轮。这种珩磨工艺是在该公司的D—250机床上进行的。待精珩的工件齿轮支承在机床的前后顶尖上,穿过具有内齿的珩磨环并与之啮合,珩磨环由机床带动进而驱动工件齿轮。该机床可用来精珩两个串列齿轮组中较小的一个齿轮,珩磨环的齿顶圆较大,不致与串列齿轮组中的大齿轮齿顶发生干扰。
Fássle rAG, Switzerland, specializes in gear honing finishing. The company employs a unique honing method to hone ordinary spur gears and external helical gears, which are actually large internal gears. This honing process is carried out on the company’s D-250 machine. The workpiece gear to be machined is supported on the front and back apex of the machine tool, passes through and meshes with a honing ring having internal teeth, and the honing ring is driven by the machine tool to drive the workpiece gear. The machine can be used to fine-tune the smaller one of the two tandem gear sets, which has a larger addendum circle and does not interfere with the large gear tip in the tandem gear set.
