contra rotating prop gearbox 3d models

A second gear has been added to stabilize the shat gears and make the forward/revers rotation smother. 1.75 filament is use as guide pins to align the halves while gluing it together. 1.75 filament should be inserted in the 2 holes to secure the...

Props for supermarine Seagull flyingboat.

This is a mechanism to drive to transparent plastic colored discs as part of an art installation. ...The gears are SLS nylon.

contra rotating turbine on solid works

I've been working on a project with my kids to study aircraft with contra-rotating propellers, such as the  P51 Racer. I decided to also try and study how to CAD herringbone style gears. These are uncharted waters but I thought it worth sharing as is...

A contra-rotating propeller system consists of two propellers rotating in opposite directions co-axially. Not to be confused with counter-rotating propellers, which refers to two propellers rotating in opposite directions mounted on different...

Modeled in OnShape. I attached a small motor to make it spin. A small pin (cut from a toothpick or something similar) should be inserted to hold the middle gear in the tube. If you appreciate my designs and would like to support my work, consider...

You can add as many turbines as you like and set them to rotate in any direction you want. The included brackets are designed for 34mm pipes, but you can use zip-ties to attach the shaft to a pole. ... You can see it in action here: ...

Himax CR6320 Contra-rotating motor without added adapters and props.This assembly is equipped to drive two 21” propellers with each of its 240 KV motors https://www.maxxprod.com/mpi/mpi-266.html

... motor. ...This assembly contains two motors stacked atop each other that drive two separate propellers. It is built for 9" propellers or lower. 1300 KV motor (https://www.amazon.ca/Brushless-Contra-Rotating-CRM2413-Airplane-propellers/dp/B07D7SYPMK)

This gear is the handcrank gear which powers the whole contraption.place “gear no2” in the middle slot, the two gears should mesh.place “gear 3” in the leftmost slot (left being the side without rounded edges), this gear is the first one with an...

The contra rotating propellers minimize the torpedo's spin, making it travel farther and more efficiently. A pin (like part of a toothpick) is required to hold the middle gear in the casing. A small motor can fit inside, along with small batteries. ...

This contra-rotating spinner will create interesting geometric patterns and is just plain fun to play with. It is a fast print, with no support required, and a great conversation starter.  Print Settings: V2. STL and V2-Mirror.STl: Infill 30%,...

Himax CR3516 Contra-Rotating Electric Motor with 12x6 EP APC and 11x8 E APC Props. ...Accurately modeled in detail.

As closely modelled on the Hobby King contra rotating DC motors as possible, I need this for a design project and I don't actually have the real motors on hand (yet) so the dimensions and such are best guesses from what I could find online. In short,...

This is my second entry for the RASSOR challenge.The configuration consists of two sets of contra-rotating drums with helical shaped single scoops.The simmetric configuration makes the reaction forces between the ground and the scoops to completely...

The rear propeller for contra-rotating drives has a very large tapered hole, making user balancing difficult with most commercially available balancers. This spindle snaps into the hub with friction fit. I made mine with PLA on a .175 resolution...

I have this motor for my RC hovercraft. I'm currently 3d modelling it so that I might make some 3d printed parts. Not the motor but hovercraft. ...So far only no stator or windings.

Replacement for the small metal arm which rotates the barrel of Denix replica revolvers. Seems this part has a tendency to break but there are no replacement parts available. ... Feel free to remix or adjust as needed.

- Finally fished body - Gun is upgraded a lot and will shoot well if strong material is used - This is just the gearbox, the gun body will come soon, but this works by itself - I scratched the last one and just finished this one yesterday + yes i...
