Last up to 5 times longer than regular plastic gears
Tested and proven: gears made of iglidur have a considerably longer service life than machined or injection-moulded gears made of regular plastics.
What material is better for what type of gear?
The Formula Student Team from Weingarten near Ravensburg needed, amongst other things, customised polymer pinions to construct their racing cars. The pinions were used as chain tensioners in the chain drive, so they had to be especially robust. Unfortunately, pinions in special sizes have long delivery times, and classic production by means of milling is time-consuming. The igus® 3D printing service allowed polymer pinions to be delivered and tested in less than 72 hours. The material used was iglidur I6, which is especially wear-resistant – it was still fully functional after one million cycles in laboratory tests – and was ideal for use in racing cars. In this case, the special parts from additive manufacturing were not only available much faster, but were more robust and economical.
For constructing e-bikes it is especially important that the components used are light and quiet. Lars Hartmann from the VMA Getzmann GmbH, which produces stirring, dispersing and fine-grinding systems, tested sprockets printed in 3D made of iglidur I3 as replacement for metal sprockets and was enthusiastic:
"The standard metal pinion generates a lot of noise when in use. We drew it and had it printed by igus® from iglidur I3. The way to the part was simple and fast. We used the 3D printing service to upload the corresponding data, chose the material and ordered the quantity."
Easelink, a company from Graz, has developed "Matrix Charging", a charging system that automatically connects the bottoms of electric cars with the power supply when they are parked. To design the system to be both economical and high-quality, the designers have chosen gear prototypes made of iglidur polymers with additive manufacturing. The igus® 3D printing service allowed sample components to be quickly ordered, tested and adjusted until the ideal solution was reached. iglidur I6, an especially wear-resistant, self-lubricating laser sintering powder, is ideally suited to the design of gears, pinions and other heavily stressed components that usually must be regularly lubricated and maintained, and which frequently require replacement.
