滚珠丝杠传动螺母的螺纹表面相对于外径的偏摆参数可看成是 h 或 H 量的变化(图1)。由于螺母内螺纹中有椭圆形的滚珠回程槽,因此,测量仪的测头必须按照螺距严格地对准表面螺旋线,并且当测头或测头与引导元件一起进入螺纹缺口时,必须消除测头沿螺距方向上的自身运动。根据设计要求,这样测 H 值的变化是比较方便的。 The deflection of the threaded surface of the ball screw drive nut relative to the outside diameter can be taken as a change in h or H (Figure 1). Due to the oval ball return groove in the nut internal thread, the measuring probe must be aligned with the surface helix strictly in line with the pitch and must be removed when the probe or probe is brought into the threaded notch with the guiding element Head moves in the direction of the pitch. According to the design requirements, this change in H value is more convenient.
