ABSTRACT: Since the profile of guide roller for tapered roller through-feed superfinishing is a complex helical surface, the profile grinding of the guide roller is a complex issue. The analytical expression of grinded guide roller profile was established based on principle of conjugation surface. The features of axial sectional shape of grinded guide roller profile were characterized by two parameters including roll contour taper angle and roll contour concavity. Through numerical calculation, it analyzed the influences of grinding machine-related parameters on grinded guide roller profile, and results show that roll contour taper angle is most affected by grinding wheel angle, while slightly affected by grinding wheel diameter and grinding-wheel-rack vertical pendulum angle; On the other hand, roll contour concavity is most affected by grinding-wheel-rack vertical pendulum angle most, more affected by grinding wheel diameter, and merely affected by grinding wheel angle. With a guide roller of special structure, it measured the roll contour concavity of grinded guide roller profile and obtained the outcome results which were in consistence with numerical calculation results.
