可采用对研的方法精加工大型螺旋锥齿轮。采用这种方法时,虽然齿轮的材料经过选择,并且质量经过检查,但是仍然不能完全消除由于热处理所产生的误差。然而,用硬质合金刀盘可以精切经过粗加工后表面淬火的螺旋锥齿轮,并能用很短的时间切除淬火变形而完成齿轮的精加工。齿轮的表面和精度相当于磨过的相同规格的圆柱齿轮,齿面粗糙度在3至5微米之间,切齿精度达到DIN39655级。由 Research methods can be used to finish large spiral bevel gear. With this method, although the material of the gear is selected and the quality checked, the error due to heat treatment can not be completely eliminated. However, the use of hard alloy cutter can be precise after roughing surface quenched spiral bevel gear, and can be quenched in a very short period of time to complete the gear deformation and finishing. The surface and accuracy of the gear is equivalent to the same cylindrical gear with the same specification. The tooth surface roughness is between 3 and 5 microns, and the precision of gear cutting reaches DIN39655 level. by
