一些看似简单的维修小工艺,往往会给你带来不小的便利,如能掌握下面介绍的小经验,则将事半功倍。1.巧卸螺检经常会碰到一些直径较大的螺栓拆卸困难,这是因为当初拧紧螺栓时,在螺纹的工作面上已经产生了较大的摩擦力;随着使用时间的延长,由于螺纹之间金属的“咬蚀”和锈蚀,摩擦力进一步增大,即使用加长杆扳手拆卸,螺栓仍无松动。此时用锤子猛击螺栓六角头数次,使螺栓轴向产生振动,导致其螺纹间出现“裂痕”,边击边卸,这样即可将螺栓拆卸下来(见图1a)。对有螺母的螺栓,可用刷子、汽油先清洗掉裸露螺纹上的油污、锈蚀等,锤击螺母后再拆卸(见图1b)。
Some seemingly simple maintenance of small craft, often bring you no small convenience, if you can grasp the small experience described below, it will be more effective. 1. QMU often encounter some large diameter bolt disassembly difficulties, because the original tighten the bolt, the screw face has produced a large friction; as the use of time, due to the extension of time, due to Thread between the metal “bite corrosion” and corrosion, further increased friction, even with the extended lever wrench disassembly, the bolt is still loose. At this point, the hexagon head of the bolt is punched with a hammer several times, causing the bolt to vibrate in the axial direction, resulting in a “crack” between the threads of the bolt, which can be disassembled and disassembled so that the bolt can be disassembled (see FIG. 1a). For bolts with nuts, use a brush and gasoline to clean the grease, rust, etc. on the exposed threads, and then remove the nuts by hammering them (Figure 1b).
