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.,它广泛应用于汽车、机械、电子、航空航天等领域，可加工各种螺纹，如内螺纹、外螺纹、螺母等,如果滚珠丝杠拧不下来，可能是由于以下原因： 1. 滚珠丝杠过紧：这可能是因为杠杆或扳手力度过大而导致滚珠丝杠过紧, 5. 螺纹孔：螺纹孔通常用于固定轴承座和滚珠丝杠轴之间的连接, 5. 轴向基准：即螺母的轴向偏差，通常以公差等级来控制精度，如IT10、IT11等,大头通常是由钢材或铸铁制成，它的形状和大小取决于所连接的设备的要求,滚珠丝杠的制造材料主要包括以下几种： 1. 钢：滚珠丝杠的滚珠和螺杆一般采用高强度的合金钢或不锈钢材料制造, 2. 检查滚珠丝杠的滚珠是否存在磨损、缺失、变形等现象，如有需要更换滚珠,在手动旋转时，由于滚珠丝杠的螺旋形状，滑块沿着螺旋线移动，从而实现线性运动, 滚珠丝杠防尘套通常由橡胶、塑料或金属材料制成，其形状和大小根据滚珠丝杠的尺寸和形态而定
