【 摘 要 】

Surface roughness is a key measurement index of the surface quality of the cold roll-beating forming rack, which directly affects the contact conditions, fatigue strength, wear resistance and corrosion resistance of the gear parts when engaging. In view of the surface quality problem of cold roll-beating forming rack, the influence of process parameters on the surface roughness of the tooth wall is analyzed, and the mathematical calculation model of surface roughness is established. The forming test is carried out on the self-designed cold roll-beating equipment to measure the roughness of the sidewall of the forming rack, and the correctness of the calculation model is verified.
