Models We Love

We enjoyed being able to bring some incredible new content to you last week with our new series featuring the coolest, most detailed models on GrabCAD.

This week we look at three models in the automotive and machine design category. Beautiful models with strong attention to detail and some interesting stories behind them. Take a look and let us know what your favorite is!

Planetary Gearbox

by Simon M
Machine Design
STEP/IGES

As Simon says, “this is a project we did in team for an engineering class of machine elements. This is a planetary gearbox to drive an openable stadium roof. This gearbox is composed of 4 planetary stages wich brings the the ratio to 215:1. The output torque wich it was design for is about 10000 lbs*ft @ 2 RPMIt ain’t fully engineered, there’s a lot of guesswork and rules of the thumb in the design. But every shafts, bearings, gears, keyways and splines have been engineered.”

Firewood Processor

by Mezo Sandor
Machine Design
STEP/IGES

This model is an actual product being developed by the company Mezo works for. It’s about 70% complete, but even at this stage it has som much detail and some many interesting parts to it that it would be a shame to pass up a look at this model.

Mecanum Wheel

by Nesher Amir
Machine design
Solid Edge ST4 / SpaceClaim

We have a lot of Mecanum wheel models on GrabCAD, but this one has got to be one of the most detailed of the bunch. That said, it’s missing a lot of little components as Nesher points out in the comments. Stop on over and encourage Nesher to finish it up!
