Description

PDF

    A Educational Gearbox setup for kids or students passionate of mechanics and engineering. Its a good demonstration of a 2 stage planetary gearbox used for high torque applications with a 16:1 reduction gear ration.

    The model takes some skill to make and is not a very easy one but the result is worth it and you will increase your printing skills and mechanical understandings. The design can work without lubrification but I highly suggest putting some if its possible.

    In conclusion if you want a educational project to understand mechanics better or just something fun to have on your desk, this is the one.
