3. 运行时间：如果需要长时间运行，需要选择功率更高的电机以确保电机不会过热,其特点是可靠性高、寿命长、精度稳定、运行平稳等, 6. 将两次读数之差即为滚珠丝杠螺纹的长度,此外，它们还经过特殊的润滑处理，以减少摩擦和磨损，从而延长滚珠丝杠的使用寿命,滚珠丝杠连接电机的过程包括以下几个步骤： 1. 选择合适的滚珠丝杠：根据需要传递的力矩和转速等要求，选择合适长度、直径和螺距的滚珠丝杠, 6. 封闭部件：用于保护滚珠丝杠内部免受污染和损坏，常见的封闭方式有盖板、防护罩等, 4. 长度要求：根据需要确定模组长度, 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. Keywords: ball screw; lifting machine; transmission efficiency; load capacity; dynamic response,在选择SKF滚珠丝杠产品时，建议选择SKF滚珠丝杠授权经销商以获得更好的产品和服务保障,在实际应用中，如果要达到更高的重复定位精度，可以采取一些措施，如增加丝杠的预紧力、加装防抖装置等
