摘　　要：对MoS2干膜润滑和航空润滑油润滑的凹口螺栓进行了施加扭力时的预紧力测试,试验结果表明:施加相同扭力时MoS2干膜润滑凹口螺栓较航空润滑油润滑凹口螺栓的预紧力大,亦拧紧螺栓时施加较小的力矩可获得较大的预紧力,这是很有工程价值的现象。The mechanical properties of notch bolt are tested under MoS2 dry-film lubrication and aviation lubricating-oil under pretightening force when we have brought torque to bear on notch bolt . The experimental results indicate that the pretightening force under MoS2 dry-film lubrication is larger than that under aviation lubricating-oil. In other words,when a notch bolt is fixed,less torque can make larger pretightening force. This is a very valuable engineering phenomenon.
