Induction Hardening of Engineering Machinery Parts

Common Induction Hardened Engineering Machinery Parts

Gears: After induction hardening, the gears in engineering machinery have improved tooth surface hardness, wear resistance and fatigue resistance, can withstand greater loads, and extend service life. For example, the gearbox gears of loaders can adapt to harsh working environments after induction hardening.

Shaft parts: such as the drive shaft of excavators and the drum shaft of winches, induction hardening can improve the hardness and wear resistance of the journal surface, enhance its wear resistance and fatigue resistance, and ensure the transmission accuracy and reliability of the shaft.

Track shoes: The track shoes of engineering machinery such as bulldozers and excavators can improve the surface hardness and wear resistance through induction hardening, especially the pitch part and pin hole surface of the track shoes, which can effectively resist the wear of soil, rocks, etc., increase the service life of the track shoes, and reduce maintenance costs.

Sprocket: Sprockets for construction machinery such as bulldozers and excavators

Through induction quenching, the hardness of the sprocket tooth surface can be greatly improved, generally up to HRC55-62, thereby enhancing the wear resistance of the tooth surface, resisting the wear when the chain and sprocket mesh, and extending the service life of the sprocket.

Induction quenching forms a hardened layer of a certain depth on the sprocket tooth surface, so that the tooth surface has a high residual compressive stress, which can effectively improve the fatigue strength of the sprocket, withstand frequent impact loads, and reduce the occurrence of fatigue cracks.

According to the working requirements of the sprocket, the parameters of induction quenching can be accurately controlled to achieve a hardened layer distribution with a specific shape and depth on the tooth surface, such as obtaining a suitable hardened layer depth at key locations such as the tooth top and tooth root, and improving the overall performance of the sprocket.
