Sintered Metal Planetary Gear
Sintered metal planetary gears are a type of planetary gear manufactured using powder metallurgy technology. It is widely used in many industrial fields and is an indispensable basic component for the development of various industrial products such as automobiles, home appliances, audio equipment, office equipment, agricultural machinery, precision machinery, etc.
- Product Introduction
Advantages of sintered metal planetary gears
1.High load-bearing capacity: After gear precision cutting, quenching, surface quenching or carburizing quenching treatment will be carried out to improve hardness and enhance load-bearing capacity.
2.Good self-lubricating performance: By utilizing the porous nature of the sintered body, it is immersed in 10% -40% (volume fraction) lubricating oil, which can be used in a self supplied state. During operation, the temperature of the liner increases. Due to the larger expansion coefficient of oil compared to metal, the oil will automatically enter the lubricating surface to lubricate the liner. Adding oil once can last for a long time and is commonly used in situations where refueling is inconvenient.
3. Low cost: Compared to gears manufactured by some traditional processing methods, sintered metal planetary gears have lower manufacturing costs.
4.High precision: Although gears inevitably deform during heat treatment, processes such as grinding, grinding, or precision cutting are carried out after heat treatment to eliminate errors caused by deformation and improve gear accuracy.

FAQ
Surface treatment methods for sintered metal planetary gears
1.Heat treatment and subsequent processing
To improve hardness, sintered metal planetary gears are usually subjected to heat treatments such as quenching, surface quenching, or carburizing quenching after gear precision cutting. However, in heat treatment, gears inevitably undergo deformation, so grinding, grinding, or precision cutting must be carried out after heat treatment to eliminate errors caused by deformation and improve the accuracy of gears.
2.Immersion lubricant treatment
By utilizing the porosity of sintered bodies, sintered metal planetary gears can be impregnated with 10% -40% (volume fraction) lubricating oil, allowing them to be used in a self supplied state. During operation, the temperature of the liner increases, and due to the larger expansion coefficient of oil compared to metal, it automatically enters the lubrication surface to lubricate the liner. Powder liners can be used for a long time after adding oil once, and are commonly used in situations where refueling is inconvenient.
3.Surface polishing treatment
Precision gear chain mirror polishing machines and other equipment can be used to perform surface treatment on sintered metal planetary gears, for removing burrs, machining tool marks, chamfering, mirror polishing, precision polishing, and other operations. It is suitable for surface processing of various precision small parts, gears, etc.
