Sergei Mishin’s research paper and accompanying video show a unique gearbox design using 3D printed parts alongside brass rollers that can be used to create a compact right-angled gearbox.
The advantage of this design is that it enables the use of a 3D printed complex crown gear, whilst utilising the strength and precision of the brass rollers, rather than having two plastic parts meshing.
The potential drawbacks are that labelling the design as “zero backlash” may be ambitious, and the design relies on 3D printing, which is not as readily accessible as more traditional methods.
However, this design provides another potential solution for makers to create interesting and unique mechatronic projects that require angular gearboxes.
