The specific property of motion is determined. And the negative effect of the skating motion of ball on this drive is discussed. It provides theory basis for force analysis and parameters designing of the tooth flank structure.

• 通过对滚珠环面蜗杆副滚珠的运动速度、运动轨迹的分析,得到该型传动副的传动特性,同时确定了滚珠的滑移运动方向及其对传动效率和承载能力的负面影响,为滚珠蜗杆副承载能力分析及齿面滚道参数设计提供了理论依据
