Gear processing methods include forming method and generating method. The forming method is to mill the tooth Valley directly with the gear forming milling cutter. The advantage is that the gear can be obtained on the milling machine. When the equipment is limited, many disadvantages should be considered. In order to reduce the number of tools, the number of teeth is divided into segments, and one cutter is used for each segment of teeth. In this way, the tooth profile will bring systematic error.

The generating method is to use the generating motion formed between the cutter and the gear to process and the gear. There are mainly hobbing and gear shaping. Hobbing is processed by simulating the meshing of worm gear. Gear shaping is processed by simulating the meshing of two gears. Gear hobbing is mostly used because the tooth profile of the gear hobbing hob is linear and convenient for processing, while the gear shaper tool is such a shovel backed gear, and the tooth profile is involute, which is not convenient for processing. However, gear shaper can be used in some positions where hobbing cannot be processed, such as internal gear and double or multiple gear with too short tool withdrawal distance. In the finishing of gears, there are shaving and grinding

Gear hobbing machine gear hobbing machine can process oblique teeth with 8 dies or less; Milling machine milling teeth: can process straight rack; Slotting machine gear: it can process internal teeth; Gear beating of cold beating machine: it can be processed without chips; Gear planer: it can process 16 module large gears; Precision cast teeth and low-cost pinion can be manufactured in large quantities; Gear grinding machine: it can process the gear on the precision host; Casting teeth of die casting machine: most of them process non-ferrous metal gears; Gear shaving machine: it is a kind of metal cutting for finishing gear.

The above is an introduction to gear processing methods and product classification. If you need gear processing, please consult IHF Hefa gear manufacturer.
