Abstract

The invention discloses a gear machining process. The gear machining process comprises the following steps that raw materials for making a gear are prepared and comprise, by weight, 9-12 parts of C, 4-6 parts of Cr, 900-1000 parts of Fe, 20-25 parts of Mo, 5-7 parts of Ni, 25-30 parts of Ti, 12-16 parts of Nb, 3-6 parts of Be, 3-6 parts of Ta, 3-6 parts of Zr, 3-6 parts of V, 3-6 parts of W, 3-6 parts of aluminium nitride, 4-7 parts of rare earth element, 4-7 parts of nanometer zirconium dioxide, 15-20 parts of surface treating agent and 50-80 parts of nitrogen, and mixed powder raw materialsA are put into a gear mold to be pressed and formed under pressure of 600-620 Mpa. The powder is made into the gear, the efficiency is high, a finished product is good, and the gear machining processis suitable for being popularized.

Description

Technical field [0001] The invention relates to the technical field of gear processing, in particular to a gear processing technology. Background technique [0002] Gear refers to a mechanical element with gears on the rim that continuously meshes to transmit movement and power. The application of gears in transmission appeared very early. At the end of the 19th century, the principle of the generative gear cutting method and the special machine tools and tools that used this principle to cut gear appeared one after another. With the development of production, the smoothness of gear operation was paid attention to. [0003] Powder metallurgy technology can produce parts that require high dimensional accuracy and complex shapes in a shape that is very similar to the shape of the product, and can greatly reduce cutting costs. Therefore, powder metallurgy products are used in many ways as parts of various machines and devices. [0004] The existing gear has a single material, low str...
