Wear-resistant, high-temperature resistant and noise-reducing, Mercedes-Benz can use this PEEK to replace metal gears

Evonik has recently developed a PEEK molding compound with very good friction properties and high durability.
Gears made from it can meet the harsh application environment of internal combustion engines and replace metal gears
.

It is understood that there is a component in the internal combustion engine called the mass balancer, which ensures the smooth operation of the internal combustion engine by reducing the vibration caused by the piston on the surrounding structure
.
Mass balancer gears are usually made of metal due to their constant contact with engine oil and exposure to high temperatures of up to 130°C
.

VESTAKEEP PEEK can now be used to manufacture low-wear outer ring gears for plastic gears in mass balancers
.
This series of components is produced by IMS Gear SE & Co KGaA and used in various models by Mercedes-Benz AG

According to reports, VESTAKEEP PEEK 5000 G is a wear-resistant high-performance material
.
Plastic gears made of it have lower friction losses and are very quiet in operation compared to metal gears
.
These plastic gears also save energy due to their light weight and can be manufactured cost-effectively by injection molding, avoiding the need for extensive rework adjustments like when using metal
.

Evonik is advancing the development of this material in close cooperation with customers through its own gear testing platform
.
“We can generate material-specific data that can be used to optimally design inch wheels made of high-performance PEEK
.
We can also test at temperatures ranging from -20°C to 260°C, both in dry conditions and in The tests can be performed under lubricated conditions,
