细读了裘国华同志“自行车前后轴设计初探”一文,(见《自行车科技》1987年第2期)结合我厂在轴挡的球道半径对耐磨和灵敏度的影响的研究,提出自己的见解,为方便起见,本文的代号尽可能与自行车前后轴设计初探(以下简称初探)一文相同。由于轴碗的接触应力远较轴挡为小,本文仅分析轴挡的受力情况,但其原理是相通的。 Read the article on “Design of bicycle front and rear axles” by Comrade Qiu Guohua (See “Bicycle Technology”, No. 2 of 1987) Combined with the research on the influence of fairway radius on wear resistance and sensitivity of our factory, For convenience, this article’s code as possible with the bike before and after the shaft design (hereinafter referred to as the initial exploration) the same article. As the shaft bowl contact stress is much smaller than the shaft block, the paper only analyzes the axial block force situation, but its principle is the same.
