发动机的连杆螺栓在工作中承受着巨大的冲击和交变载荷,一旦断裂,将发生打烂机体和活塞、撞坏连杆和曲轴等重大事故,所以必须谨慎加以维护。 1.连杆螺栓必须完好无损。当发现有断丝、滑扣、弯曲、伸长或裂纹等,应及时更换新件;完好的连杆螺钉一般能用手拧入一半以上的螺纹深度。 2.从连杆上拆下连杆螺栓后,应及时将原螺母拧上;如果是螺钉,也要拧入原来那个螺孔内,以免配合位置错乱。 The connecting rod bolt of the engine is subjected to huge impact and alternating load at work. Once it breaks, major accidents such as breaking the body and the piston, crashing the connecting rod and the crankshaft will occur, so care must be taken to maintain it. 1. Connecting rod bolts must be intact. When a broken wire, sliding buckle, bending, elongation or cracks, etc., should be promptly replaced with new pieces; intact rod screw can generally be screwed into more than half the depth of the thread. 2. Remove the connecting rod bolt from the connecting rod, the original nut should be promptly screwed on; if it is a screw, but also screwed into the original screw hole, so as to avoid confused with the location.
