怎样安装高速精密角接触球轴

2017-12-18 16:59:58

高速精密角接触球轴承,主要用于载荷较轻的高速旋转场合,要求轴承高精度、高转速、低温升低振动和一定的使用寿命。常作高速电主轴的支承件成对安装使用,是内表面磨床高速电主轴的关键配套件。



主要技术指标:

1.轴承精度指标: 超过GB/307.1-94 P4级精度

2. 高速性能指标: dmN值 1.3~1.8x 106 /min

3. 使用寿命(平均): >1500 h



高速精密角接触球轴承使用寿命与安装有很大关系,应注意以下事项:

1. 轴承安装应在无尘,洁净的房间内进行,轴承要经过精心选配,轴承用隔圈要经过研磨,在保持内外圈隔圈等高的前提下,隔圈平行度应控制在1um以下;

2. 轴承安装前应清洗干净,清洗时内圈斜坡朝上,手感应灵活,无停滞感,晾干后,放入规定量油脂,如属油雾润滑应放入少量的油雾油;

3. 轴承安装应采用专门工具,受力均匀,严禁敲打;

4. 轴承存放应清洁通风,无腐蚀气体,相对湿度不超 过65%,长期保管应定期防锈。
