Introduction
Powder metallurgy is a developing technology widely used in various industries. It has been widely used in the production of parts such as powder metallurgy gears, bearing retainers, connecting rods and seals. With the development of powder metallurgy technology and the improvement of powder metallurgy products, powder metallurgy double sided gear is one of the important parts of powder metallurgy.
Development history
The development of powder metallurgy double-sided gear has a long history. The earliest powder metallurgy double-sided gear appeared in the 1950s, and has been widely used in various fields since the 1960s. At first, the production of powder metallurgy double-sided gear was mainly concentrated in Europe and the United States. With the rapid development of powder metallurgy technology, this technology has also been introduced to China, and the production of powder metallurgy double-sided gear has been further enriched in terms of materials, varieties and applications.
Structure of powder metallurgy double-sided gear
The structure of the powder metallurgy double-sided gear is composed of a gear body, a gear shaft and a bearing. The material of the gear body is generally a kind of soft metal, such as aluminum alloy or iron, and the material of the gear shaft is usually made of stainless steel or chrome steel. Both the gear body and the gear shaft are usually treated with surface finish such as anodizing and electroplating.
Advantages of powder metallurgy double-sided gear
The advantages of powder metallurgy double-sided gear are mainly reflected in the following aspects:
1. Powder metallurgy double-sided gear has good strength and wear resistance. The hardening process makes the gear have a hard and wear-resistant surface and core, thus greatly improving the surface wear resistance and service life.
2. Powder metallurgy double-sided gear has good heat dissipation and oil retention properties. The combination of heat treatment and lubrication makes the heat dissipation rate and oil retention ability of the product improved, thus providing a more favorable working environment.
3. Powder metallurgy double-sided gear has good impact resistance and high precision. The surface hardness and core hardness of the gear can reach m151hb, and the gear surface and core are both heat treated and quenched, thus improving the impact resistance and precision of the gear.
Limitations of powder metallurgy
Although powder metallurgy has been widely used and developed, it still has certain deficiencies in material selection, processing and product quality.
1. Material selection deficiencies. At present, powder metallurgy is mainly used for the production of some small parts, and the choice of materials is limited to some soft metals. However, for some large components, such as automotive shaft, the material selection of powder metallurgy is still very limited.
2. Processing defect. Due to the limitation of the main equipment, powder metallurgy can only realize certain processing technologies, and can not be applied to some complicated processes.
3. Product quality defect. The precision and accuracy of the products made by powder metallurgy are also limited, which affects the use effect of the products.
Development prospects and future development direction
In the future, powder metallurgy double-sided gear will still be the focus of powder metallurgy industry. At present, new materials, refinement and processing technologies are needed to make powder metallurgy technology play a greater role. For example, through the selection of special materials and the combination of two processing technologies, the precision and performance of powder metallurgy double-sided gear can be improved, so as to meet the needs of more industries. At the same time, with the in-depth application of powder metallurgy technology, new powder metallurgy processing technologies will gradually mature. Through the combination of these processing technologies, the processing range, precision and accuracy of powder metallurgy double-sided gear will be improved, thus providing better products for the development of powder metallurgy.
Conclusion
Powder metallurgy double-sided gear is a new trend for powder metallurgy technology to develop new products. The development of powder metallurgy double-sided gear has a long history and is widely used in various fields. Powder metallurgy double-sided gear has the advantages of good strength and wear resistance, heat dissipation and oil storage, impact resistance and high precision. Although there are some limitations in material selection, processing and product quality, new materials, refinement and processing technologies can be applied to make powder metallurgy technology play a greater role. In the future, powder metallurgy technology will make continuous progress and provide better services for the industry.
