Introduction to two common gear processing principles

The gear processing process roughly goes through the stages of blank heat treatment, gear blank processing, tooth profile processing, tooth edge processing, tooth surface heat treatment, fine datum correction and gear profile finishing. There are two common gear processing principles. It is a modeling process, a model research process and a model analysis process. The gear processing process roughly goes through the stages of blank heat treatment, gear blank processing, tooth profile processing, tooth edge processing, tooth surface heat treatment, fine datum correction and gear profile finishing.

The first stage of gear processing is when the tooth plaque from gear processing first enters the processing stage. The main factors that determine the gear transmission accuracy of gear machining are the accuracy of tooth profile and the uniformity of pitch distribution, which is directly related to the accuracy of gear grinding (using condenser) positioning standard. Next, prepare the accuracy standard. The basic accuracy of tooth hole and feed machining needs to use the specified technology. In addition to machining the base in the first stage of gear machining, in the second half of this stage, as much machining is carried out on the second surface as possible in addition to the tooth profile.

Gear processing the second stage of gear processing is tooth profile processing. For the gear processing that we do not need quenching, we must be able to process the gear that does not match the pattern completely through this step. The gear that needs to be quenched by processing enterprises must be improved to meet the tooth profile accuracy required for trimming the tooth profile at this development stage, which is an important research step to ensure the technical accuracy of gear processing. You must pay special attention to yourself. The three stages of treatment are heat treatment. In gear machining, the main problem is to harden the tooth surface at this basic stage so that the tooth surface has a predetermined hardness. The stage of gear machining is the stage of tooth profile finishing. At this stage, the tooth profile deformation caused by gear quenching is corrected, the tooth profile accuracy is further improved, the surface roughness is reduced, and the accuracy requirements are met.

At this stage, first prepare the reference surface (hole and end face), but due to the quenching deformation of the inner hole and end face of the gear, the tooth profile finishing based on the hole and end face requires the gear accuracy. It is difficult to maintain the original state after quenching. In order to achieve the purpose of gear processing, make the gear processing positioning accurate and reliable, and the gear processing distribution more uniform.
