After the standard heat treatment of the drive wheel blank of our sprocket, the hardness of the substrate reaches above HB235, and the drive teeth are subjected to medium frequency induction hardening and low temperature tempering. The surface hardness can reach HRC48-54, and the hardening depth is higher than 5-10mm (HRC45). It not only provides accurate power under harsh working conditions, but also has excellent wear resistance and has the effect of extending product life and reducing customer costs.

How to avoid tooth breakage in sprocket
The protective measures reasonably determine the design parameters. When optimizing the design of the sprocket parameters, in order to improve the bending strength of the sprocket, a larger sprocket modulus should be selected within the range permitted by the conditions. Considering that during the use of the equipment, due to the increase in output, equipment aging, Factors such as product changes cause the sprocket load to increase, and the safety factor should be greater than the critical value.
Improve the machining accuracy and installation accuracy of the sprocket. Increasing the radius of curvature of the fillet at the transition of the tooth root to eliminate machining tool marks there. Pay attention to the detection and elimination of internal material defects. Increase the rigidity of the shaft and support, improve the installation accuracy, and avoid large vibrations and eccentric loads.
Reasonable choice of materials and heat treatment methods. Eliminate fine cracks and residual stresses during processing and heat treatment, especially when grinding sprocket wheels, properly select the material, hardness and grinding process parameters of the grinding wheel to avoid grinding cracks.
Use equipment properly, maintain good lubrication, avoid frequent starting and reversing during running-in period, do not overspeed, underload, check regularly, choose a lubricant of appropriate viscosity, and replace the lubricant regularly to avoid tooth breakage due to wear.
