Iglidur I3 in 3D printing
Quiet e-bikes: sprocket comes out of the printer
In order for e-bikes to run as quietly as possible, both the drives and the installed components must be optimized accordingly. Igus offers individually manufactured drive elements such as sprockets made from high-performance plastics using the 3D printing process. The special solutions are lubrication- and maintenance-free and reduce the noise level.
Growth rates in the sale of e-bikes have been high for years - 605,000 e-bikes were sold in Germany alone in 2016, which corresponds to an increase of 13 percent. In order to be able to grow with the market as a drive manufacturer, continuous further developments are necessary. This is why the motors for the 2018 e-bike model year are around 25 percent smaller than their predecessors, weighing around three kilos and making less noise while riding. However, e-bike tinkerers like Lars Hartmann from Reichshof are not satisfied with this. The excessive noise of the bicycle chain was a thorn in his side. A metal sprocket acted as a pulley on the chain to prevent it from colliding with the frame. However, the metal sprocket caused immense running noises.
In search of a remedy, Lars Hartmann turned to the 3D printing service from Igus. He sent the CAD data of the desired sprocket to the company and received the custom-made special solution within a few days. The perfect solution for the hobbyist: "The standard metal sprocket made a lot of running noise. I drew it out and had it printed from Iglidur I3 at Igus," explains the tinkerer. "The process was quick and easy. With the 3D printing service, the relevant data could be uploaded as a STEP file, the material selected and the desired quantity ordered." The sprockets have been in use in two bikes for two months now - and the background noise has been significantly minimized, Hartmann is pleased to report.
Optimum wear values and strength
The material used, Iglidur I3, is also suitable for industrial and small-series applications. Igus refers to the good wear values and high strength and the processing is carried out using selective laser sintering (SLS). In addition, the manufactured parts can be used directly. In the test laboratory, plain bearings made from the material have already been compared with the most commonly used materials for selective laser sintering. The parts were at least three times more abrasion-resistant than standard materials in swivel, rotational and linear motion. as
