Description

Technical Field

[0001] The utility model relates to the technical field of gear milling machines, in particular to a large-scale thrust combined gear milling machine. Background Art

[0002] Gear processing is a specialized field in mechanical processing. Traditionally, gear milling is performed by various types of gear hobbing machines, gear hobbing cutters, and finger milling cutters as conventional tools. Compared with other processing fields (turning, milling, boring, and drilling), the production efficiency has been greatly improved due to the use of a large number of advanced tools. However, the gear processing tools have not changed much, resulting in little improvement in production efficiency. This is mainly because the tool material for gear milling is mostly high-speed steel, which is more suitable for grinding involute surfaces. However, because of the use of high-speed steel, the cutting speed is much lower than that of hard metal, and a large amount of lubricating coolant is required to improve the durability of the tool. Short service life, low cutting efficiency, and high tool manufacturing cost are the common characteristics of gear processing tools. The gear hobbing machine for processing external cylindrical gears is a kind of machine tool with a transmission mechanism connected to each other, and the transmission coefficient and transmission accuracy requirements are very high. The price of machine tools, especially large gear milling machine tools, is relatively expensive, so general mechanical processing plants, except for special reducers and gear machine professional factories, will not be equipped with many gear hobbing machines, and the production capacity is limited. If mass production of gears occurs, it becomes urgent to improve the gear processing efficiency, or first solve the problem of fast rough milling of gears.
