“How long will my printed gear last?” New igus online tool predicts lead time
Published on: 23rd April 2019
Free online expert provides concrete statements on the service life of wear-resistant 3D-manufactured gears
How long will my gear last? To answer this question, igus has now developed the gear service life calculator for its 3D-printed gears made of the laser sintering high-performance plastic iglidur I3. With the new online tool, the user receives a concrete statement in a few seconds about the service life of the wear-resistant part.Get the precise service life in just three steps
In step 1, the user must first enter the number of teeth, the width and the tooth module of the gear pairing again. Here the customer can choose between iglidur I3 gears, a metal or another plastic. In step 2, the tool asks for the speed and torque of the large or small gear, depending on the which gear’s values are available. Step 3 is to determine the duty cycle of the printed gear, the mode of operation, the ambient temperature and the safety factor. Based on the specified parameters, the new online tool can determine the service life of the 3D printed gear in seconds. This makes maintenance predictable in advance.
Printed gears convince in the pivot test
The high-performance plastic iglidur I3 has been specially developed for the production of wear-resistant parts such as gears in the laser sintering process. The material is abrasion-resistant and durable, as shown by an experiment in the company’s own 3,800 square metre test laboratory. Here, the gear made of iglidur I3 took on a POM injection-moulded gear and a POM machined gear in a pivot test at 1440°C at a speed of 0.1 m/s and a torque of 2.2 Nm. All gears had 30 teeth and a width of 16mm. While the injection-moulded gear made of POM failed after just 4,000 cycles and the machined POM gear broke down after 12,500 cycles, the iglidur I3 gear withstood almost 20,000 cycles.
