摘　　要：超大型轴承因为尺寸大、质量大,导致在钻孔过程中轴承容易调整不灵活,定位也不准确,针对上述情况设计了一种钻孔用的可旋转支撑装置。此装置针对超大型轴承套圈的特性,提供一个可完成旋转、支撑的工作台,有效地解决了大兆瓦轴承套圈安装孔的倒角和攻丝的加工问题,提高了工作效率。Due to the large size and heavy mass of ultra large bearings,the bearing adjustment is not flexible,meanwhile,the positioning is not accurate during the drilling process.In response to the above situation,a rotatable support device for drilling has been designed.This device provides a workbench that can complete rotation and support based on the characteristics of ultra large bearing rings,effectively solving the problems of chamfering and tapping machining of installation holes for large megawatt bearing rings,and improving work efficiency.
