小型柴油机飞轮滚键后,把键棱角滚去,而且飞轮与曲轴上的键槽都要不同程度地受到损害。严重的曲轴与飞轮都会断裂。因此,对滚键应以防为主,发生滚键后要及时发现、及时解决。滚键的原因有以下几点: 1.螺母未上紧在安装飞轮时,应该一面向里敲击飞轮边缘,一面紧固飞轮螺母。可加长扳手手柄,上紧后将锁紧垫片锁好。否则,柴油机工作时,飞轮会松动滚键。有的柴油机飞轮长期不拆卸会锈死,待需要拆卸时非常困难。因此,有人怕将来难拆卸,就故意不装紧。这很容易造成飞轮松动,这种办法是不可取的。为解决这个问题,安装时可在曲轴锥面上涂
After the small diesel engine flywheel rolls, the keys and corners roll off, and the flywheel and the keyway on the crankshaft should be damaged in varying degrees. Serious crankshaft and flywheel will be broken. Therefore, the rolling key should be based on prevention, after the rolling key should be found in time, resolved in time. Rolling keys for the following reasons: 1. The nut is not tight When installing the flywheel, it should be one side inwardly flywheel edge, one side of the flywheel nut. Can be extended wrench handle, tighten the lock washer lock. Otherwise, when the diesel engine is working, the flywheel will loose the rolling key. Some long-term diesel engine flywheel rust will die, to be dismantled very difficult. Therefore, some people are afraid of being disassembled in the future. This is very easy to cause loose flywheel, this approach is not desirable. To solve this problem, the installation can be coated on the crankshaft cone
