滑块式万向接轴广泛用于各类机械传动中,以往其扁头的强度计算多采用密诺维奇的经验公式,它是假定滑块和开口扁头间的接触压力呈三角形分布。经验公式法有一定的实用价值,但有许多不足之处,有些问题尚待进一步探讨:(1)经验公式所算出的是扁头的最大计算应力值,但未确定出最大计算应力的所在部位;(2)不能得到扁头体应力变化规律;(3)所算出的最大
Sliding universal joints are widely used in various types of mechanical transmission, the past calculation of the strength of the flat head to use more Mi Nuoweiqi empirical formula, it is assumed that the contact pressure between the slider and the opening triangular distribution. Empirical formula method has some practical value, but there are many shortcomings, some of the issues to be further explored: (1) empirical formula calculated is the maximum calculated stress of flat head, but did not determine the location where the maximum calculated stress ; (2) can not get the head body stress changes; (3) the calculated maximum
