PEEK material properties and its role in gears

• PEEK is a special engineering plastic with excellent performance, high temperature resistance, excellent mechanical properties, good self-lubrication, chemical corrosion resistance, flame retardant, peel resistance, irradiation resistance, insulation stability, hydrolysis resistance and easy processing characteristics.
• Long-term operating temperature range from -100 ℃ to +250 ℃, at the same time with thermoset plastics heat resistance, chemical stability and thermoplastic molding processability.
• PEEK's long-term use temperature is about 260-280 ℃, short-term use temperature can reach 330 ℃, and high pressure resistance up to 30MPa, is a good material for high-temperature gears.
• PEEK also has good self-lubrication, easy processing, insulation stability, hydrolysis resistance and other excellent properties.

Gear engineers are under pressure to improve reliability, increase efficiency, and reduce vibration, noise, and acoustic roughness, while striving to achieve smaller components and minimize overall system costs. This presents an excellent opportunity for PEEK materials, which are particularly well suited for high-performance gear applications, replacing the role of traditional metals in gears.

Types of PEEK GEARS:

• PEEK Spur gears:

Spur gears, by combining different numbers of teeth and modules, can be varied in size, strength, and so on. In addition, the accuracy of gears is mainly affected by factors such as the presence or absence of tooth grinding, while the hardness of gears is affected by factors such as material variations, heat treatment and the presence or absence of shafts.

• PEEK Helical gears:

The components of a helical gear are mainly the helix angle, helix direction, and the gear reference surface. As in the case of spur gears, the size, accuracy and hardness of the gears vary with the number of teeth, module, lapping or non-lapping, material and heat treatment, respectively.

• PEEK Internal gears:

Internal gears have teeth on the inner circle and are usually used in planetary gear mechanisms. As a toothed ring, it meshes with the planetary pinion. If the number of teeth of the internal gear and the planetary gear does not meet certain conditions, problems such as involute curve interference, hypoid interference and shear interference often occur.

• PEEK Rack and pinion:

Rack and pinion is a gear with teeth distributed on a strip. It meshes with a pinion gear to convert rotation into movement. A rack can be thought of as a cylindrical gear with an infinite indexing radius. For this reason, it is often used in machine tools and automatic operating systems. A helical rack is a rack with an inclined tooth line

• PEEK Equal Bevel Gear:

Equal Bevel Gear is a type of bevel gear. When used in pairs, two bevel gears are usually required to have the same number of teeth and the angle between the shafts of the two gears is 90 degrees. As with general bevel gears, there are two types of bevel gears: helical and straight. In addition, there is also a kind of helical cross equal diameter bevel gears, their shaft angle is usually not 90 degrees.

• PEEK Bevel Gear:

Bevel gears (bevel gears) are gears with a conical shape. It is generally used to transmit motion and power between two intersecting axes, and is divided into two types: arc-toothed bevel gears and straight-toothed bevel gears.

• PEEK Spiral Gear:

Staggered shaft helical gears are helical gears (cylindrical) in which the center axes of the two gears are neither intersecting nor parallel. Since staggered shaft helical gears transmit power by sliding of the meshing teeth, they are not suitable for high loads and require adequate lubrication.
