How to reduce the price of heavy truck gear products quenching cracking and deformation?

First of all, it is necessary to correctly select the material price of the heavy truck gear and reasonably design the tooth shape. Secondly, it is necessary to correctly prepare heat treatment and casting. The blank should obtain satisfactory organization through appropriate preparatory heat treatment, such as normalization, annealing, tempering treatment, etc., to adapt to the requirements of mechanical processing and heat treatment. When casting heavy truck gear blanks, it is necessary to minimize casting defects, which are easy to cause cracking and deformation of the gear during quenching. And the price of heavy truck gear should adopt reasonable heat treatment process. When heating, try to heat evenly to reduce the thermal stress during heating; For large heavy truck gear prices, preheating should be used. Choose the appropriate quenching temperature, in general, try to choose the lower limit of quenching temperature. Correct selection of quenching medium and cooling method, under the premise of meeting the performance requirements, should choose a more moderate quenching medium, or use fractional quenching, isothermal quenching and other methods.
