主轴部件的刚度对机床的工作性能有重大影响。影响主轴部件刚度的因素很多,其中支承跨距对其刚度的影响局势复杂,是双向的,有一合理值,设计过大、过小都会使其刚度降低,从而影响传动件的工作状态和机床的加工效率和精度。要找到合理值,传统的办法是先计算出η=EJ/k1a3值,然后查图表,再计算。由于图表的中的图线有限,计算既麻烦,又无法精确。本文介绍的优化设计方法,可以既快又精确的计算出主轴部件支承跨距的合理值,有较高的实用价值。
The stiffness of the spindle components has a significant impact on the performance of the machine tool. There are many factors affecting the rigidity of the spindle components, including the impact of the span of the support stiffness of its situation is complex, is a two-way, there is a reasonable value, the design is too large, too small will reduce its rigidity, thus affecting the transmission parts of the working conditions and machine tools Processing efficiency and accuracy. To find a reasonable value, the traditional approach is to first calculate η = EJ / k1a3 value, and then check chart, recalculate. Due to the limited chart lines in the chart, calculations are cumbersome and inaccurate. This article describes the optimal design method, you can quickly and accurately calculate the spindle component support span of the reasonable value, with high practical value.
