在 JB 2886-81《机床梯形螺纹丝杠、螺母精度》中,对丝杆规定了螺距、半角和中径公差。但是对螺母只在第12条规定:“螺母的螺距和半角公差由半径公差控制”。这句话含意不明确──螺母的螺距和半角误差引起的半径误差是在中径公差中控制呢?还是将螺母的螺距和半角误差引起的中
In JB 2886-81 “machine tool trapezoidal thread screw and nut precision”, the screw pitch, half-width and diameter tolerance. But for nuts only under Article 12: “The pitch and half-width tolerances of the nut are controlled by the radius tolerance”. The meaning of this sentence is not clear ─ ─ nut pitch and half-angle error caused by the radius error is controlled in the diameter tolerance it? Or the nut pitch and half-angle error caused by
