1.忌“宁紧勿松” 在汽车修理中,由于受“配合间隙宁紧勿松,螺丝扭力宁大勿小”的习惯做法的影响,在调整各部间隙时,不按修理规范要求调整,往往间隙贪偏小,降低了机械效率,有时甚至造成机械故障。在拧紧各部螺丝时,习惯于拧得越紧越好,不使用扭力扳手,致使一些安装螺丝受过大的拉力,在机械工作时断裂或脱扣(有时甚至在拧紧过程中当即扭断),而且易引起零部件配合面的变形。
1. Bogey “Ning tightness not loose” In the car repair, due to “with the gap not tight tight, screw torsion bigger than the small” the impact of the practice, when adjusting the gap between the ministries, do not press the repair specification requirements adjustment, Often gap smaller, reducing the mechanical efficiency, and sometimes even cause mechanical failure. When tightening the various screws, it is customary to tighten as tight as possible without using a torque wrench, causing some mounting screws to be subjected to excessive pulling forces, to rupture or to trip (sometimes even to tighten during tightening) during mechanical work, and Easily lead to parts with the deformation of the surface.
