Gear processing technology

Release time:2024-06-20

Gear ring tooth processing is the core of the entire gear processing. Gear processing has many processes, these are for the tooth processing services, the purpose is to obtain the final accuracy of the gear.

According to the processing principle, the tooth profile can be divided into forming method and expansion method. In addition, in the non-standard design will also be used in line cutting and powder metallurgy for gear processing, which powder metallurgy on the application of pinion processing is more extensive.

Forming method is a method of cutting the tooth surface with a forming tool that is consistent with the shape of the tooth groove of the cut gear, such as milling teeth, pulling teeth and forming grinding teeth.

The spawning method is a method for the gear cutter and the workpiece to cut out the tooth surface according to the meshing relationship of the gear pair, such as gear hobbing, gear cutting, gear shaving, gear grinding and gear honing.

The choice of tooth profile processing scheme mainly depends on the accuracy grade, structure shape, production type and production conditions of the gear,

8 precision below gear, quenched and tempered gear with hobbing or gear can meet the requirements. For hardened gears, the processing scheme of rolling (inserting) teeth one tooth end processing one quenching one correction hole can be adopted. However, the machining accuracy of tooth profile before quenching should be improved by one level.

Grade 6~7 precision gears can be used for hardened gears, coarse gear hobbing, fine gear hobbing, tooth end processing, fine gear shaving, surface quenching, correction reference, gear honing.
