6. 对刀具进行质量检验，确保其满足设计要求，如尺寸精度、刀齿形状等, 4. 将滚珠逐个放入滚道内，注意不要让滚珠滚落, 3. 在矫直过程中，应将滚珠丝杠的两端支撑好，以避免矫直力度不均导致滚珠丝杠进一步变形, 4. 环境要求：根据设备的工作环境，选择耐高温、耐腐蚀等特殊性能的冷轧滚珠丝杠型号,其结构主要包括电机、减速器、滚珠丝杠、导轨以及外壳等组成部分, 一般来说，滚珠丝杠的圆弧偏心量越小，其精度和稳定性就越高，但生产成本也会相应提高,具体价格需要根据具体需求进行询价, 2. 选择合适的滚珠丝杠型号和规格，根据滚珠丝杠的外径、螺纹间距、螺距等参数计算出滚珠丝杠的基本参数, 关键词：滚珠丝杠；升降机；传动效率；负载能力；动态响应 Abstract: This paper mainly introduces the structure and working principle of the ball screw lifting mechanism, and analyzes and evaluates its performance. Firstly, the basic principle and classification of the lifting machine are introduced, and then the structure and working principle of the ball screw lifting mechanism are introduced in detail, including the ball screw, guide rail, motor and other components. Then, the performance of the ball screw lifting mechanism is analyzed and evaluated, mainly including transmission efficiency, load capacity, dynamic response and other aspects. Finally, the advantages and disadvantages of the ball screw lifting mechanism are discussed, and some improvement measures and application prospects are put forward.
