[0002] The working condition of engine crankshaft is complex, and it bears bending-torsional fatigue load, torsional vibration and wear during operation. Strengthening the surface of the crankshaft by using glow ion nitriding method is very important to improve the service life of the crankshaft. The crankshaft is the most important component in the engine. It bears the force transmitted by the connecting rod and converts it into torque to drive other accessories in the engine. The crankshaft is subjected to the combined action of centrifugal force of rotating mass, periodic variation of gas inertia force and reciprocating inertia force, so it bears bending-torsional load. Therefore, the crankshaft requires sufficient strength and stiffness, and the journal surface needs to be wear-resistant, uniform in operation and good in balance.

[0003] Currently, glow ion nitriding is carried out at a certain temperature, and the nitriding time is long. The crankshaft is easy to bend and deform, which will make the straightness of the crankshaft exceed the tolerance range and be scrapped. The crankshaft produces bending and torsional deformation, which is often caused by excessive impact load on the crankshaft. When the engine is in use, serious knock or sudden start will cause the crankshaft to bear a large impact load. Especially when the engine has accidents such as burning tile and shaft seizure, the crankshaft is easy to bend and twist. Therefore, a crankshaft protection device for ion nitriding is needed to improve the above problems. UTILITY MODEL CONTENTS
