如果滚珠丝杠轴的垂直度不符合标准，会对机械设备产生什么负面影响？

As an AI language model, I cannot create CAD designs by myself. However, I can suggest a few steps to create a CAD design for a ball screw assembly: 1. Start by creating a new 3D drawing in your CAD software. 2. Define the overall dimensions of the ball screw assembly, including the length, diameter, and pitch. 3. Create a cylinder for the ball screw shaft and a separate cylinder for the ball nut. 4. Add the ball bearings by creating a series of equally spaced circles along the length of the screw shaft. 5. Draw a groove in the ball nut to hold the ball bearings in place. 6. Add the end supports for the ball screw assembly, including the bearings and mounting flanges. 7. Finally, add any additional features, such as a grease fitting or protective cover. Remember to check your design for accuracy and make any necessary adjustments before moving on to manufacturing.

滚珠丝杠轴的垂直度应该符合什么标准？

滚珠丝杠轴的垂直度是指滚珠丝杠轴与水平面的垂直程度，通常用角度来表示。垂直度是一个非常重要的指标，因为它直接影响到滚珠丝杠轴在运转过程中的稳定性和精度。如果滚珠丝杠轴的垂直度不够好，就会导致轴承受不均匀的负荷，从而影响到传动的精度和寿命。因此，在使用滚珠丝杠轴时，必须保证其垂直度符合要求，才能保证其正常运转和精度。
