• 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。
• Thirdly , through assaying the error generated during measuring data , the result manifests : 1 ) the location installed of the transducer and the point thumped affects the experiment result to some extent . if surface - opening cracks is deeper , the location of the transducers installed and the point thumped should be further away from the location of surface - opening cracks . 2 ) when the depth of surface - opening cracks is near to 50mm , it is very difficult to measure the depth of surface - opening cracks because the depth of r _ wave conveying in concrete plates from the different small ball bringing forth exceeds 50mm . 3 ) it is clear from the experiment result , the influence is n ' t big for the diameters of small balls to measure the data while the time interval between two transducers touched firstly has very big influence on the result
  其次，对测量数据进行了误差分析，结果表明： ( 1 )传感器及敲击点的位置对实验结果有一定的影响，当开口裂纹的深度较深时，传感器和敲击点的位置应该离裂纹较远； ( 2 )当开口裂纹深度接近50毫米时，由于实验中所使用的小球产生的r波传播深度均超过50毫米，故很难测量出其开口裂纹的深度； ( 3 )实验发现，小钢球直径的大小对裂纹深度的测量结果影响并不是很大，但是，波的开始上升和下降点的测量精度(即两信号的时间延迟) ，对测量的结果有很大的影响。
