3. 长寿命：Hph3048采用高质量的滚珠和优化的润滑系统，具有很长的使用寿命和稳定的性能,此外，滚珠丝杠模组还采用了进口高精度滚珠，使得传动精度更高, 6. 长寿命：采用高精度的滚珠丝杠和直线滑轨，能够保证长期稳定的使用寿命,How to draw a ball screw in Taichung in English: 1. Start by drawing a horizontal line to represent the base or bed of the machine or equipment where the ball screw will be installed. 2. Draw a vertical line at the center of the base line to represent the axis or centerline of the ball screw. 3. Draw a circle at the top of the vertical line to represent the ball nut, which is the component that houses the balls that roll along the screw shaft. 4. Draw a screw thread around the vertical line, starting from the bottom and going up towards the ball nut. The screw thread should be spiraled around the vertical line and should have a constant pitch or distance between each thread. 5. Draw a set of balls inside the ball nut, arranged in a circular pattern and evenly spaced apart. The balls should be in contact with the screw thread and should be able to roll freely along the shaft. 6. Draw two end supports or bearings at each end of the ball screw, which are used to support and guide the screw shaft. The end supports should be cylindrical in shape and should have mounting holes for attaching to the machine frame. 7. Finally, add any additional details or features such as seals, lubrication ports, or covers to complete the drawing.,选择合适的螺母和垫圈要考虑以下几个因素： 1. 尺寸：螺母和垫圈的尺寸要与滚珠丝杠相匹配，确保配合良好,假设我们选择了6.35mm的滚珠，那么计算公式为： 转角 = π/4 × 滚珠直径 / 丝杠直径 = π/4 × 0.00635m / 0.004m ≈ 2.50 载荷 = 0.5 × 9.81N ≈ 4.91N 滚珠载荷能力 = 1.83 × 10^-3 × 滚珠直径^3 滚珠载荷能力 = 1.83 × 10^-3 × (0.00635m)^3 ≈ 1.67N 载荷 / 滚珠载荷能力 = 4.91N / 1.67N ≈ 2.94 动载荷系数 = 1.25 静载荷系数 = 3 滚珠直径 = (载荷 / (动载荷系数 × 静载荷系数))^(1/3) × 转角 × 丝杠直径 / π 滚珠直径 = (4.91N / (1.25 × 3))^(1/3) × 2.5 × 0.004m / π ≈ 6.94mm 因此，我们需要选择6.94mm的滚珠直径, 3. 优化滚珠丝杠的结构：优化滚珠丝杠的结构，如优化滚珠丝杠的导轨、改善滚珠丝杠的密封性等方式，可以提高滚珠丝杠的精度, 无刷电机是一种直流电机，通过无刷技术实现了换向器的无接触运作，具有高效率、低噪音、长寿命等优点, 2. 油润滑不足：滚珠丝杠需要润滑油来减少摩擦，如果油润滑不足，滚珠容易在丝杠上卡住,1. 准备工具和材料：托板滚珠丝杠、扳手、螺丝刀、润滑油等
