Sergii Gordieiev, creator of Youtube channel “The Q,” has developed a working chainless bicycle utilizing a sequence of 3D printed plastic gears. The system consists of 1 giant gear related to 4 smaller gears that switch rotational movement from the pedals to the rear wheel.
The gear system requires exact alignment and measurements to operate correctly. If one gear slips out of place, your entire drivetrain fails to function. Gordieiev painted the initially white plastic gears orange to make them extra seen when driving the bicycle.
In his YouTube video, Gordieiev demonstrates the development course of, together with constructing the body modifications wanted to mount the gear system. He first examined the gears on a wood floor earlier than putting in them within the place sometimes occupied by a bicycle chain. The ultimate small gear connects on to the rear wheel’s hub, finishing the mechanical linkage.
The undertaking showcases how 3D printing can create customized bicycle elements at dwelling. Customers can doubtlessly change broken gears with out visiting a motorcycle store, utilizing commonplace 3D printing filaments. Whereas at the moment solely the gears are 3D printed, the strategy might prolong to different bicycle components for additional customization.
