it is the minimum clearance space intended between mating parts and represents the condition of tightest permissible fit.
它是配合零件之间最小的预期间隙空间,代表着允许的最紧配合条件。
fretting damage exists on tightly mating parts at large, which is one of the disaster reason making components and parts fail.
微动损伤普遍存在于紧密配合部件中,是造成零部件失效的主要祸患之一。
secondly, it is used as a method of obtaining very close fits between mating parts such as pistons and cylinders.
其次,它能用作获得像活塞与气缸之类配件间过盈配合的方法。
in mass production, where mating parts must be interchangeable, unilateral tolerances are customary.
大规模生产中配合零件必须能互换,单向公差是经常遇到的。
the heat-transfer effects between the mating parts and the fluids including the sealed fluid and air were studied.
对机械密封与试验介质间和大气间的传热效应作了一定深度的研究。
proper torquing avoids elastic separation of the mating parts under load and resists gradual loosening over time.
扭矩正确,就能防止配合部件在负荷作用下出现弹性分离,并防止部件在长期运转过程中逐渐松动。
friction alone between the mating parts of the assembly shall not be acceptable as a means to prevent turning.
利用两配合部件之间的摩擦来作为防止扭转的一种方式是不能接受的。
