这种技术可以减小机械零件的磨损,提高手表的精度和耐用性,
3. 检查丝杠的螺纹是否损坏或变形,如果有,需要进行修复或更换,
6. 储存:储存滚珠丝杠时,应保持干燥、清洁和防尘,以延长其寿命,滚珠丝杠串动是指当滚珠丝杠在工作过程中,滚珠之间的间隙过大或滚珠的数量不足,导致滚珠在滚动过程中出现跳动或间隙,进而影响丝杠的稳定性和精度,
因此,滚珠丝杠的预紧力失效对机器的性能和寿命都会产生严重影响,需要及时进行维修或更换, 关键词:数控机床;滚珠丝杠副;精度;应用领域 Abstract: This paper introduces the structure, working principle, accuracy and application fields of the ball screw pair of CNC machine tools.

Starting from the structure and working principle of the ball screw pair, this paper elaborates the working process and accuracy requirements of the ball screw pair in detail. The application fields of the ball screw pair of CNC machine tools are summarized and summarized, and its important role in the field of high-precision machining is elaborated. Keywords: CNC machine tool; ball screw pair; accuracy; application field 一、引言 数控机床是一种高精度、高效率、高自动化的加工设备,在现代制造业中占有重要地位,在连接时需要注意以下几点:
1. 选择适当的轴承:轴承需要承受传动力和转矩,因此需要选择适当的轴承类型和规格,
7. 经济:滚珠丝杠应具有经济性能,以降低成本和提高市场竞争力,
2. 调整滚珠丝杠前后间隙时,应确保滚珠丝杠的径向间隙不变,否则会影响滚珠丝杠的精度和寿命,它由滚珠丝杠和滑块组成,滚珠丝杠是一种具有螺纹的轴,上面覆盖着滚珠圆珠,滑块则是一种可以沿滚珠丝杠上下移动的构件
