| 摘 要： | 介绍一种新型水基薄膜润滑剂。仅利用该润滑剂对高强度螺栓连接副中的螺母表面进行润滑处理,即能够达到以下目的:处理后的磷化大六角头螺栓连接副,在0～60℃时,其扭矩系数及标准偏差均满足GB/T1231—2006《钢结构用高强度大六角头螺栓、大六角螺母、垫圈技术条件》的要求,且温度每变化10℃,扭矩系数的变化率仅为2.7%;处理后的磷化扭剪型螺栓连接副,在0～60℃时,其紧固轴力均满足相关标准要求,且其标准偏差远低于标准允许范围;处理后的达克罗大六角头螺栓连接副,其扭矩系数及标准偏差亦能够满足相关标准要求。 |
| 关 键 词： | 润滑剂 高强度螺栓连接副 扭矩系数 紧固轴力 标准偏差 |

| Abstract: | This paper presented a new water-based film lubricant , only by which the lubricating treatment of the nut of high strength bolting pair was implemented , and can the following objectives be achieved : The torque coefficient and standard deviation of the phosphating large hexagon head bolting pair can meet the requirements of GB / T 1231-2006from 0℃to 60℃ , and the torque coefficient changes only 2.7% when the temperature changes every 10 ℃ ; the fastening axial force of the torshear type bolting pair can meet the requirements of relative standards from 0℃to 60℃ , and the standard deviation is much lower than that of the allowable range ; the torque coefficient and standard deviation of the dacromet large hexagon head bolting pair can also meet the requirements of relative standards. |
| Keywords: | lubricant high strength bolting pair torque coefficient fastening axial force standard deviation |
