循环球式汽车转向器在汽车工业生产中应用愈来愈广泛,其结构也日臻完善。而此种转向器中的转向螺母通常采用双圆弧滚道螺旋副。由于其结构的特点,在实际生产中给有关参数的测定带来了一定的困难。本文就其双圆弧滚道螺母钢球中心距 D_o 的检验值 M_0的确定及修正作初步的分析与探讨。一、问题的提出钢球中心距 D_0是双圆弧滚道螺母(以下简称滚道)的主要参数之一。D_0的精度直接决定螺杆、螺母、螺旋副的传动效率及总成
Recycling ball car steering gear in the automotive industry is more and more widely used, its structure is also improving. The steering gear in the steering nut is usually double arcuate raceway helix. Due to the characteristics of its structure, in the actual production to the determination of the parameters has brought some difficulties. In this paper, the determination and correction of the test value M_0 of the center distance D_o of the double arc raceway nut are analyzed and discussed. First, the question raised Ball center distance D_0 is double arc raceway nut (hereinafter referred to as the raceway) one of the main parameters. D_0 accuracy directly determines the screw, nut, screw pair transmission efficiency and assembly
