1.紧固螺母未拧紧。在安装飞轮上时,应一面向里敲击飞轮边缘,一面紧固飞轮螺母,拧紧后将锁紧垫片锁好。否则,飞轮将会由于振动而松动发生滚链。有的柴油机飞轮长期不拆卸会锈死,需要拆卸时非常困难。因此,有些机手怕将来难拆卸,安装时故意不安紧,这很容易造成飞轮松动而滚链。为防止飞轮锈死,安装时可以在曲轴锥面上涂一层机油,难拆时可以用加大的拉拔器外拉,并结合敲打振动飞轮边缘。
1. Tightening nut is not tightened. When installing the flywheel, one side of the flywheel should be hit in the edge, one side of the flywheel nut, tighten the lock washer lock. Otherwise, the flywheel will be loose due to vibration roller chain. Some diesel flywheel will not rust long-term disassembly, dismantling very difficult. Therefore, some aircraft are afraid of difficult to disassemble in the future, the installation of deliberately nervous, it is easy to cause the flywheel loose and roller chain. In order to prevent the rust of the flywheel, the engine can be coated with a layer of oil on the cone of the crankshaft during installation. When it is difficult to disassemble, it can be pulled by the extra puller and combined with the edge of the vibrating flywheel.
