roller chain wheel sprocket (1)
The service life of the sprocket is short, which is far from meeting the requirements of production practice. According to the use condition of the sprocket, processing status, and manufacturing technology, some improvement measures have been proposed for the sprocket. Follow the editor of the roller chain wheel sprocket to understand Right!
The original sprocket design material is 40Cr, the overall quenching and tempering hardness is HB220~250, and the tooth part is quenched HRC48~52. This method basically cannot improve the wear resistance of the sprocket due to the limited hardness of the tooth quenching. It is recommended to change the sprocket material to 20CrMnTi, carburizing and quenching treatment, the chain socket hardness can reach HRC60 or more, and its wear resistance is more than 2.5 times that of 40Cr material. This can greatly increase the service life of the sprocket, reduce the frequency of machine repairs, increase productivity, and reduce production costs;
