Custom maintenance-free toothed belt pulleys delivered in just 48 hours

igus reduces delivery time and makes online ordering of custom toothed belt pulleys particularly easy with its latest 3D-print offering

28 JULY 2022 – Motion plastics leader igus® announced it is expanding its 3D-print and online ordering offering to include custom format toothed belt pulleys.

Toothed belt pulleys are a common component in many machines and are widely used in linear drives of printers, robots, and packaging machines. However, if an individual variant is required, developing a custom component can take days or even weeks.

“The delivery times for such custom parts often amount to several weeks,” says Tom Krause, Head of Additive Manufacturing at igus. “To shorten delivery times for special-format belt pulleys, we now offer manufacturing by 3D printing, reducing delivery times from several weeks to just 48 hours.”

Tribo-plastics from igus ensure longer service life

In the igus in-house 3,800 square meter test laboratory, the high-performance polymer iglide® i3 competed against an injection-molded and a milled spur gear made of polyoxymethylene (POM) in a pivot test at a speed of 0.1m/s, a torque of 2.2Nm and an extreme temperature of 1,440°C (2,624°F). All spur gears had a width of 16mm and 30 teeth. The result: the milled spur gear failed after 12,500 cycles, and the injection-molded variant after 4,000 cycles. The 3D-printed gear made of iglide i3, on the other hand, withstood almost 20,000 cycles.

“In addition to iglide i3, we also offer the FDA-compliant version i6 for the food sector and the electrostatically dissipating variant i8 for explosive areas,” says Krause. “All high-performance plastics are robust and wear-resistant enough to be an economical and reliable alternative even to steel and aluminum belt pulleys.”  

Use the online configurator to place your order in just a few minutes

The production of toothed belt pulleys with flanged wheels is particularly complex and is difficult to produce from a single piece of metal using lathes and milling machines. However, the 3D-print service from igus speeds up manufacturing because the parts are printed in one piece, and the online configurator makes it easy to order.

Customers can upload a CAD model of their part via drag-and-drop on the website to determine a price immediately and place the order. If the customer doesn’t have a digital model, they can configure one within minutes using the belt pulley configurator. Users simply enter specifications such as belt profile and the number of teeth. The configurator then creates a STEP file that users can upload to the website.

“Calling back and forth or sending CAD models by e-mail are time-consuming steps that have become much easier thanks to the online configurator. This has enabled us to speed up the ordering process and give designers a further time advantage.”
