nsk滚珠丝杠的工作原理是利用滚珠在丝杠与导轨之间滚动，实现高精度的线性运动,顶紧力的大小需要根据具体的应用情况和滚珠丝杠的规格来确定,这包括丝杠的价格、维护费用和寿命等方面,滚珠丝杠具有高精度、高刚性、高效率等特点，常用于需要较高精度和速度的场合，如数控机床、自动化生产线等,同步带和滚珠丝杠都是传动机构中常见的零件，它们的精度对于机械设备的性能和使用寿命有着重要的影响, 3. 负载过大：滚珠丝杠反相器在工作时，承受的负载过大，容易导致滚珠丝杠反相器受损,它具有高精度、高刚度、高效率、长寿命等优点，能够满足高速、高负载、高精度和长行程的要求,滚珠丝杠可以手动和电动两种方式来进行操作, 关键词：滚珠丝杠；剪叉式升降台；设计；制造；实验验证 Abstract: This paper introduces the design and manufacturing process of a ball screw scissor lift table. The lifting platform adopts a scissor structure and a ball screw drive, which has the advantages of good stability, high precision, and long service life. In the design process, SolidWorks software is used for 3D modeling and finite element analysis, and the strength calculation of key components is carried out. In the manufacturing process, CNC machining and manual assembly are used to ensure the accuracy and reliability of the lifting platform. Finally, experimental verification is carried out, and the results show that the performance of the lifting platform meets the design requirements.
