In the modern industrial field, the performance of materials directly determines the service life, operational efficiency and overall cost of products. Among them, wear resistance, as an important indicator of a material's ability to resist wear and tear, is even more critical for gears, a key component in mechanical equipment. In recent years,
PEEK (polyether ether ketone) material for its excellent abrasion resistance, mechanical strength, chemical resistance and high temperature stability, in the selection of wear-resistant gears gradually come to the fore.
Why choose PEEK for gear manufacturing?
PEEK gears are gradually replacing traditional metal gears in today's applications due to their unique characteristics. Here are some of the reasons why PEEK gears are used:
1. Lightweight:
PEEK material has a low density (density 1.5) Compared with metal gears, it can significantly reduce the weight, thus reducing the load and inertia of the whole equipment, improving the efficiency and performance of the equipment.
Iron (Fe): 7.86 g/cm³.
Copper (Cu): 8.9 g/cm³.
Aluminum (Al): 2.702 g/cm³.
Gold (Au): 19.32 g/cm³.
Silver (Ag): 10.50 g/cm³.
Platinum (Pt): 21.45 g/cm³.
Tungsten (W): 19.35 g/cm³.
Lead (Pb): 11.34 g/cm³.
Mercury (Hg): 13.6 g/cm³.
In addition to this, there is information on the density of some other metals:
Osmium (Os): 22.59 g/cm³, the densest metal in the world.
Iridium (Ir): 22.65 g/cm³.
Palladium (Pd): 12.02 g/cm³.
2. High temperature resistance:
PEEK has good high-temperature resistance, can be operated for a long time in a high-temperature environment without deformation or failure, suitable for aerospace, automotive engines and other high-temperature applications
PEEK gears are gradually replacing traditional metal gears in today's applications due to their unique characteristics. The following are some of the reasons for the application of PEEK gears:
1. Self-lubricating properties:
PEEK material has excellent self-lubricating properties, can reduce friction and wear, reduce energy loss and noise, extend the life of the gear, reduce maintenance costs.
2.Corrosion resistance:
PEEK on a wide range of organic solvents, oils and greases, weak acids and weak bases have the ability to resist, in addition to concentrated sulfuric acid, almost insoluble in any other acid and alkali solutions and organic solvents.
3. High strength and rigidity:
PEEK has good mechanical strength and high rigidity in plastics, even in high temperature environment can maintain good mechanical properties.
Industrial technology continues to improve the optimization, PEEK material gradually to replace the metal material as gear applications, we understand the reasons for substitution from three perspectives:
1. Easy processing:
PEEK material is easy to process and molding, can meet the manufacturing needs of complex gears, and achieve high precision size and quality control.
2. Low noise:
PEEK gears run smoothly and operate quietly, making them suitable for noise-sensitive applications such as medical equipment and office machinery.
3.Innovative thinking:
The machinability of PEEK material allows engineers to be creative and realize complex gear designs, including internal structures and details.
As technology continues to be optimized and improved to meet people's needs for products, the proportion of demand for engineering plastics in the machining industry will only increase after that.
Currently, PEEK materials are widely used in the manufacture of wear-resistant gears in many industries, including automotive, aerospace, chemical, and food processing. For example, in automotive automatic transmissions, PEEK gears enhance transmission performance and driving experience with their excellent wear resistance and low noise characteristics. In chemical pumps and agitators, PEEK gears with its chemical resistance and high-temperature stability, to ensure the long-term stable operation of the equipment.
In the future, with the continuous progress of materials science and processing technology is increasingly perfect, PEEK materials in the wear gear manufacturing applications will be more widely used. At the same time, with the enhancement of environmental awareness and the promotion of energy conservation and emission reduction policies, PEEK materials as a green, efficient engineering materials, will play a more important role in sustainable development.
In summary, PEEK materials with its excellent wear resistance, mechanical strength, chemical resistance and high temperature stability, in the selection of wear-resistant gear material occupies an important position. The selection of PEEK materials to manufacture wear-resistant gears can not only enhance the performance and service life of the product, but also promote the green development of the industrial field and energy saving and emission reduction. Therefore, the application of PEEK materials in the manufacture of wear-resistant gears has a broad prospect and is worthy of further promotion and application.
