PEEK Gears

Polyetheretherketone peek gears is a engineering plastics peek precision injection molding plastic gears, can be used in automotive transmissions, the peek gear has high temperature resistance, friction resistance, can withstand the harsh working conditions of the internal combustion engine species, peek gears can be reduced to a certain extent to the piston in the surrounding structure of the shock caused by the internal combustion engine to ensure the smooth operation of the temperature can be 130 ℃ for a long period of time in the continuous work, compared with metal Compared with metal gears, it can effectively reduce the noise by 40%.

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.

Applications

PEEK gears are used to work in the realm of automotive transmissions, electric vehicle (EV) drive, and auxiliary systems because they resist high temperatures, minimise noise and decrease weight. As examples, they are employed on mass-balance transmissions, oil pumps, AdBlue pumps, differentials, and electric engines. In practise, PEEK gears in a motorised transmission can run in engine oil up to 130°C and exhibit noise reduction over metal gears. Information indicates a maximum of 70 percent weight reduction and as much as 50 percent noise reduction and 80 percent reduction in the moment of inertia compared to metal solutions, improving NVH (noise, vibration, harshness) of powertrains.

PEEK gears are used in the aerospace sector in actuators, landing gear and flight control mechanisms due to thermal stability and ability to resist fatigue. The material enables high-torque, high-speed and high-temperature material usage and opens the possibilities of plastic gears usage beyond the limits. Fatigue measurements demonstrate the applicability of PEEK in long-lasting parts, with research on additive-manufactured PEEK gears demonstrating an improved operation by means of reinforcement such as graphite fibres and aramid fibres.

PEEK gears are used in medical devices including minimally invasive surgical devices, pumps, and diagnostic devices, and are advantaged by being biocompatible and chemically inert. Medical industry is on the forefront of its use, as PEEK facilitates lightweight mechanisms with accuracy. PEEK gears with contact fatigue life predictions, with models such as CTAB-GAN, exhibit longer life in cyclic loading conditions, typical in the medical industry.

In oil and gas mining, turbines and other energy systems, PEEK gears with extreme pressure, temperature, and corrosive conditions are resistant. They find applications in downhole tools, pumps and gearboxes in renewable energy. The results of durability tests of steel PEEK gear pairs indicate efficient coefficients of friction and temperature control, which allow one to perform under severe conditions. PEEK chemical resistance also renders it applicable to fibre optics and energy applications.

PEEK gears are found in robotics and conveyor belts in the industrial environment as well as in precision machines due to their wear resistance and self-lubricating characteristics. They are used in place of metal in planetary gearboxes and have tight tolerances and repeatability. PEEK gear fatigue strength measurements in robots indicate that high stress cycles are favourable, and options such as PEEK offer better life span. In spur gear trains, wear analysis shows that PEEK is dimensionally stable although variations can be present in the manufacturing.
