滚珠丝杠副受外载荷作用时滚珠的受力是比较复杂的,但目前在研究滚珠丝杠副滚珠受力时都是简单地按照均载来分析,这与实际的载荷分布情况有较大的偏差。建立一个变形协调条件下的滚珠丝杠副载荷分布的模型,并分析了几何误差对滚珠受载的影响。
滾珠絲槓副受外載荷作用時滾珠的受力是比較複雜的,但目前在研究滾珠絲槓副滾珠受力時都是簡單地按照均載來分析,這與實際的載荷分佈情況有較大的偏差。建立一箇變形協調條件下的滾珠絲槓副載荷分佈的模型,併分析瞭幾何誤差對滾珠受載的影響。

The stress of the bal is complicated when the bal screw is loaded by external force.However, the bal load is analyzed simply according to the average load distribution when its load distribution is researched on. This is large different from the actual load distribution. A model is developed to analyze its load distribution and geometry errors which have influence on its load disfribution.
