Gears made of iglidur® high-performance polymers enable lubrication-free and maintenance-free use.
Thanks to their special combination of base polymers, fibres, extenders and solid lubricants, they are extremely wear-resistant. Our gears have already successfully proven themselves in different applications.
iglidur® materials are thoroughly tested in our own Testlab.
In accordance with the predominant parameters in your application, we provide you with free, non-binding advice on the right materials and manufacturing and tool technology needed to form your individual gears (toothed component) in a reliable process.
You can place an order with igus with no minimum order quantity.
We will manufacture the right gears for you. Be it, e.g. with helical toothing, made of another material or specific dimensions?
We are happy to support and advise you and take care of your special solution.
The proportion of electronic and electromechanical components in vehicles has been growing continuously for years. The increased comfort and the growing safety requirements promote this development. The cable harness, which is responsible for supplying all these components, is the second-heaviest component in many motor vehicles, right after the engine. Actuators make up a large share of the elements to be supplied with power and signals.
E-bikes are becoming increasingly lighter and in addition very quiet. During operation, there are hardly any motor noises to be heard. However, resourceful inventors, such as Lars Hartmann from Reichshof, are not content with that. The bicycle chain's background noise was too loud and a thorn in his side. A metallic chain sprocket served as a guide roller for the chain to prevent it from colliding with the frame, but caused tremendous operating noise. In search of a remedy, he remembered the offer by
igus, which he had seen at a trade show: the 3D printing service , which manufactured individual components cost-effectively with a 3D printer.
Easelink, a company from Graz, has developed "Matrix Charging", a charging system consisting of two components. A charging pad connected to the mains is installed in the car park. A connector on the bottom of the e-car drops down when the car is parked over the pad. The charging process starts automatically, without the driver having to connect a cable - similar to inductive charging, but with up to ten times the charging power and with 99 per cent efficiency.
The on-site fire brigade of Fraport AG provides for fire safety at the airport in Frankfurt am Main. Its airport fire engines have roof-mounted water cannons which use a servomotor to change the angle of the spray nozzle. As this angle is also changed while water is being sprayed, the load on the servomotor is considerable. After being in use for ten years, the gears in the cannon have become worn and therefore the roof-mounted cannons must be repaired.
iglidur® gears have proven their worth in different gearboxes and have also been tested under realistic conditions of use in the igus test laboratory. For example, torque fluctuations, efficiency and backlash of the gearboxes with polymer gears are electrically measured and evaluated. The gathered empirical values allow for continuous optimisation of our gears and use in wear-intensive continuous application.
iglidur® gears are characterised by their special wear resistance in use. Due to their special material composition of base polymers, fibres, fillers and solid lubricants, they have very low wear properties and do not require additional lubricants. This extends maintenance intervals and reduces expensive downtime minutes.
A gear pinion is a round component that has uniformly distributed teeth around its circumference. It transfers force between two rotating gears or between a gear and a rack. Depending on the application, further types are used.
The most common kinds of gear pinions are:
• Spur gears (you can find them in our online shop)
• Worm gears
• Bevel gears
Different kinds of gear and toothing are often combined with each other in order to implement certain sequences of movement.
At igus, gears are made with the help of three manufacturing methods:
• Injection moulding with iglidur® granulate materials
• Mechanical processing with iglidur® bar stock as the material
• 3D printing with iglidur® SLS or FDM materials
Depending on the enquiry, we will advise you on manufacturing methods and work with you to find the best economical solution – free of charge, no strings attached.
Polymer gears are cost-effective, do not require external lubrication and are maintenance-free.
In contrast to metal gears, our polymer ones contain solid lubricants, which reduce friction.
Furthermore, certain fillers ensure an additional
improvement of the mechanical properties.
