ball diameter
spherical diameter
Examples
- Kuroda uses : oversized bal preload for light to medium loading applications , and double nut ( pin method ) for medium and higher loading applications
对于轻度以及中度载荷应用场合，黑田采用增大钢球直径的办法实现预压加载；对于高负载场合，则采用双螺母方式。 - The strength of extension of low carbon ductile cast iron can reach 750mpa in casting state , the impact ductility can reach 20j / cm2 . the diameter of graphite nodule is 5 - 20 ( am , the base body is consisted of pearlite -
低碳球铁在铸态下的抗拉强度可达750mpa ，冲击韧性可达20j cm ~ 2 ，其中石墨球直径在5 20 m ，基体以珠光体为主，有少量的铁素体与渗碳体。 - The result of study indicated preliminarily that as for the bal cage patterned constant speed universal joint , while the number of steel ball increased from 6 to 8 , on account of the reduction of steel ball diameter , not only its outside dimension may cut down 12 % , its weight could get a reduction of nearly 20 % , but also the load bearing capacity of universal joint on the contrary could gain somewhat enhancement
研究结果初步表明，对于球笼式等速万向节，当钢球数量由6增加为8时，由于钢球直径的减小，不但其外形尺寸可以减小12 % 、质量可以减少近20 % ，而且万向节的承载能力反而可以得到少许提高。 - As both the meshing point and ball ' s center are on the given cylinder , a general method for developing the cam ' s profile is studied . it is proved that the profile of positive and negative transmission is unique if the face gear , the difference between face tooth number and ball number and the diameter of ball are the same . the concrete expression of meshing cam on given spatial cycloid profile , and the characteristics of the profiles are discussed
论文的主要工作包括： 1 、根据啮合点和钢球中心轨迹均在同一圆柱面上的特点，研究了给定端齿齿廓条件下求解凸轮齿廓的一般方法；论证了在给定端齿、齿差数和钢球直径相同的条件下，正负齿差啮合齿廓的唯一性；讨论了端齿为球面摆线时，凸轮齿廓的具体表达式，并研究了该齿廓的性质。
