摘　　要：针对现有反应堆压力容器(RPV)主螺栓孔润滑存在的问题,提出了一种采用小口径出油管供油、阵列排布的刷毛旋转涂刷的涂覆方法,详细设计和研制了主螺栓孔抗咬合剂涂覆设备。该设备的试验验证结果表明,螺孔涂覆设备可将抗咬合剂均匀、完整地涂覆在主螺栓孔的螺纹表面,可有效增加螺纹副之间的润滑,降低螺纹损伤的风险。Aiming at the existing problem in the lubrication of reactor pressure vessel （RPV） stud holes, this paper puts forward an effective method which adopts array bristles and small caliber oil outlet to brush anti-seize lubricant on the surface of stud holes, and gives out the detailed design of RPV stud holes lubricating equipment. The equipment has been developed and verified by testing, and the results show that it can accomplish the uniform and complete coating on the surface of stud holes. The equipment can effectively increase the lubrication of thread pairs, and reduce the incidence and risk of thread damages.
