Technical Field

[0001] The invention relates to the technical field of gear grinding devices, and in particular to a tooth groove grinding device for agricultural machinery gears. Background Art

[0002] Gears are important transmission parts widely used in machines and instruments. There are many types of gears, and the tooth shapes are also different. The most widely used is the involute gear. Gear tooth processing is often divided into chipless processing and chip processing. Chip processing is more widely used. According to its processing principle, it can be divided into two types: forming method and developing method. The forming method is a method of directly cutting out the tooth shape with a tool profile that is the same or similar to the tooth groove profile of the cut gear. Milling, planing, and pulling belong to this method. The developing method is a method of cutting out the tooth shape by using the meshing movement of the gear tool and the cut gear. Hobbing, shaping, shaving, etc. belong to the developing method. Milling gear processing is generally a method of directly cutting out the gear tooth shape by using a dividing head on an ordinary milling machine, using a forming disc milling cutter and a finger milling cutter with the same shape as the gear tooth groove. It belongs to the forming method.
