customized ASA sprocket tells: knowledge about improvement measures of sprocket!

(Summary description)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.

(Summary description)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.

Information

The service life of the sprocket is relatively 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 customized ASA sprocket editor to learn about it. !
1. 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 repairs, increase productivity, and reduce production costs;


2. The shape of the original sprocket sprocket socket is forged and directly formed, so that the size error is large, the surface is rough, and the wear resistance is also reduced. With the wide application of CNC machine tools and the reduction of their processing costs, it is recommended to leave a little margin after forging, and finish the finishing by milling to improve the dimensional accuracy and surface roughness, so as to achieve the purpose of improving wear resistance.
In summary, the editor of the customized ASA sprocket tells: a brief introduction to the relevant knowledge about the improvement measures of the sprocket.
