Abstract

The invention belongs to the field of numerical control machining of gears and relates to a seven-shaft and six-linkage opposite angle roll cutting method for a non-circular gear. In the implementation process of the method, three fundamental frequency shafts, another three shafts linked with the three fundamental frequency shafts and an independent numerical control shaft are applied; a hobbing cutter also continuously moves along the axis of the hobbing cutter while vertically feeding; and a linkage mathematical model is disclosed. According to the seven-shaft and six-linkage opposite angle roll cutting method disclosed by the invention, all blades of the hobbing cutter can be fully and effectively utilized; cutter tooth wear is uniformly distributed; the durability of the cutter is improved; the tooth profile shape precision and the surface roughness can be improved; and the independent numerical control shaft can automatically adjust a mounting angel of the hobbing cutter, and compared with a mechanical structure, the independent numerical control shaft has the advantages of higher automatic degree, higher adjustment precision and lower labor intensity of workers. The seven-shaft and six-linkage opposite angle roll cutting method disclosed by the invention can be used for numerical control gear hobbing of non-circular spur gears, non-circular helical gears, elliptical spur gears and elliptical helical gears.

Description

technical field [0001] The invention belongs to the field of manufacturing gears or racks, in particular to the field of manufacturing gears on wheels with varying working radii, and relates to a seven-axis and six-linkage diagonal hobbing method for cutting convex curve non-circular gears. Background technique [0002] Non-circular gears include elliptical gears, oval gears, high-order elliptical gears, and deformed (sexual) elliptical gears. The (angular) velocity and (angular) acceleration become severe over time, making it difficult to process and difficult to guarantee accuracy. At present, manufacturing technology is the bottleneck restricting the popularization and application of non-circular gears, and wire cutting technology is mostly used in industry for realization. Wire cutting is not only extremely inefficient, but also powerless for helical gears. [0003] Hobbing is a high-efficiency processing method. The article "Non-circular Helical Gear Hobbing Machining...
