The F1 gearbox model is available on printables.com under indeterminate design. I don't know how well this would adapt to a motor cycle. It would be quite expensive to manufacture a custom gearbox like this and the control electronics would need to be much stronger. The disadvantage of this gearbox is that if anything goes wrong you will engage two gears and lock everything up. Check out this gearbox, it's based off the Honda MotoGP gearbox and is probably a lot better suited to a motor cycle. Unfortunately it will still be very expensive to reproduce in metal. kzbin.info/www/bejne/Znito3eJbZKhmKc

Hello ! I have no knowledge about hydrolics or robotics. But when I see the system I don't understand the advantages of going for hydrolics instead of electric actuator. As the power source is an electric motor, I think that the hydrolics are just a inefficient gearbox. What am I missing ?
@IndeterminateDesign
@IndeterminateDesign 7 күн бұрын
In many ways it is just a gearbox. The biggest reason is power density. It’s very easy with hydraulics to achieve a massive mechanical advantage by just changing the area ratios between components. This allows for actuators that are much more compact and lighter than a comparable gearbox. Additionally, a single pump can service multiple actuators. And typically all the actuators aren’t using the full bandwidth of the pump so you have less redundancy.

“Reverse is very rarely used in F1” Well, if you’re allowed 6 gearboxes for the season, I’d guess that means you can reverse no more than 6 times for the entire season. They don’t seem to like being used twice, from what little we see of drivers attempting to use reverse.

Great project! At some time I was going to try something like this too. Similarly, my idea would be to 3d print the channels and blocks but size the prints so they could be contained in stock profile metal sections. Doing this might help increase the working psi as the pressures could be transmitted from the fluid, through the print to the outer metal casing. Also, research might be needed into which hydraulic fluids can be used which won't erode the 3d print materials. Simple veg/sunflower oil might be all that is needed. My idea was to incorporate 3d printed channels for a hydraulic spool for controls and a hydraulic 360` rotating turntable junction such as used on an excavator but contained in stock metal sections.

Yeah. I think something like vegetable oil would be even better. The CHF11 I used is plant based but really thin compared to a vegetable oil. That’s an interesting idea about encasing the 3D print in metal. What kind of pressures were you trying to achieve? The passage ways in my setup are just 3mm or 1/8” and based on the strength figures for the resin that should handle close to 1000psi. But it probably doesn’t do that in the real world.

@@IndeterminateDesign resin as liquid in tested in a hydraulic press might achieve that sort of pressure. However, solid resin uncontained, is still likely to fail on the layer lines. My project still hasn't even started! However, I'm not expecting large pressures. You might find that you can indeed lift 1kg or more with the identical set up that you have but substitute a much larger bore cylinder. Lifting the load will take more time and more fluid but the system should cope. Possibly the "best" type of pump would be like an internal combustion engine in reverse - as used in construction cement pumps. Such pumps can generate huge pressures and hold the load when the pump is stopped

In addition to tolerances that floating side plates address, those standard herringbone gear shapes will allow a leakage path that effectively joins suction to pressure. If you study commercially available helical gear pumps, you will observe that much like on a screw compressor the geometries are designed with care to minimise the leakage path at the meshing point.

If you clean it with isopropyl it tends to be a slightly frosted look, but now they have special resin washes as well as water washable resins that allow you to keep a crystal clear print. You can also just dip the alchahol cleaned print back in the resin and then cure it. The added layer fills in the frosted surface to return it back to clear. I use clear things for stuff like LED lighted things etc.
