The sprocket B type triplex manufacturer tells you that the service life of the sprocket is short, which is far from meeting the requirements of production practice. According to the use status, processing status and manufacturing technology of the sprocket, some improvement measures are proposed for the sprocket:
(1) The design material of the original sprocket is 40Cr, the overall quenching and tempering hardness is HB220~250, and the teeth are quenched HRC48~52. This method basically cannot improve the wear resistance of the sprocket wheel because of the limited quenching hardness of the teeth. It is suggested to change the sprocket material to 20CrMnTi, carburized and quenched, the hardness of the chain nest can reach above HRC60, and its wear resistance is more than 2.5 times that of 40Cr material. The sprocket B type triplex manufacturer tells you that this can greatly increase the service life of the sprocket, reduce the frequency of repairs, increase productivity, and reduce production costs;
(2) The shape of the original sprocket chain socket is directly formed by forging, which has a large dimensional error and rough surface, which also reduces wear resistance. The manufacturer of sprocket B type triplex tells you that with the wide application of CNC machine tools and the reduction of processing costs, it is recommended to leave a small margin after forging and finish machining by digital milling to improve dimensional accuracy and surface roughness, so as to achieve improved durability. abrasive purpose.
