race ball 是什么意思

	1.	In the interest of adapting big size in radial direction , higher precision , higher angular rigidity , less moment of inertia , higher dynamic capability in the three - anxis simulation test turntable . researching the angular rigidity of the wire race ball bearings in axes direction , the adjustment mode and adjustment quantity to shafting , and analysing the contact stress of bearings in work is very necessity 为了适应某些仿真转台研制中关于刚度高,转动惯量尽量小,动态特性要求高等特殊要求,研究钢丝滚道球轴承的轴向支撑刚度,轴系调整方式及调整量,以及该轴承在工作中的受力及应力状况十分必要。
	2.	Foundation in to the steel wire race ball bearing contact theoretical analysis computation , and the steel wire race ball bearing main friction form analysis , gave the bearing several kind of main friction to have the form in the work process , and gave the corresponding theoretical calculation formula 在对钢丝滚道球轴承点接触理论分析计算的基础上,进行了对钢丝滚道球轴承的主要摩擦形式分析,给出了轴承在工作过程中几种主要的摩擦产生形式,并给出相应的理论计算公式。
