Description

technical field [0001] The invention relates to the field of casting materials for mechanical parts, in particular to an alloy material for casting reducer gears and a production method thereof. Background technique [0002] Metal casting is the process of smelting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling and cleaning, a casting with a predetermined shape, size and performance is obtained. With the continuous development of modern technology, electronics, machinery The demand for high-strength materials in fields such as automobiles and automobiles is increasing. It is required to reduce weight and cost as much as possible on the basis of ensuring a certain strength, so as to obtain better strength and longer service life. It is imminent to use alloy metals for casting. . [0003] Alloy is a kind of multi-performance material that helps to reduce the weight of mechanical parts. By adjusting the composition of various elem...

Problems solved by technology

[0003] Alloy is a kind of multi-performance material that helps to reduce the weight of mechanical parts. By adjusting the composition of various elements, the alloy can have high strength, wear resistance, high yield strength, high tensile strength, corrosion resistance, high Different properties such as toughness and high hardness are widely used in the casting field of mechanical parts. At present, materials with a single performance cannot meet the needs of mechanical parts. Especially in reducers, the casting of gears has higher and higher requirements for materials. Especially when the gear is working, the gear casted by traditional materials has a lot of noise and vibration, which affects the work efficiency and shortens the service life of the gear.
