    You need to flip one of the drive gears over to get all 3 banks timed perfectly. If each gear is off by 1.5 degrees, say clockwise, then flipping one gear over would make it 1.5 degrees off counterclockwise. A drivve gear mounted backwards would cancel out the timing offset.

      Nah man, you're mixing stuff up with wet sump and dry sump engines. On wet sump engines you have a pcv system that creates a vacuum in the engine by attaching a hose from the intake plenum to the crank case (or valve train area, which has a direct connection to the crank case). On a dry sump engine you create that vacuum with the dry sump oil pump and you don't have a pcv system.

    At 13:25 A lot is being made of the 3 degrees timing misalignment of those gears, but the gear to shaft interface is splined.

  • @Rayjedi

    To solve the 3* timing offset in the gearing, would it be beneficial to have another custom gear made with the inner spline for the shaft to account for the 3* offset? seems like you might be tinkering with that idea already from the marks you made on the inner spline circumference. anyways pls throw this 12 rotor in that boat of a Lincoln lol!

    Just a quick comment on the teeth timing issue.

I hope I explained that well enough! :-)

    • @peejay1981

    • @SuperBrainAK
      @SuperBrainAK Год назад +4

      Yes I think I am thinking of the same thing.
      Do not worry about the teeth of the gear being 3 degrees off. Compensate for that offset by changing the clocking of the e-shaft to the gear to accomodate for that tooth to valley offset.
      TDC on the center should have the tooth down, at the same time the left gear that is in direct contact with the center should have it's TDC at a valley pointed down.
      So yea, change the clocking of the splines to the teeth of the gear.

    This motor must have torque up the butt.... since it's firing 2 rotors at a time!! This is going to be a neat build indeed, thanks Rob and crew!!

    Rob is the saviour of all rotaries, can't imagine him doing all this several years ago but I'm happy Rob chooses this path, cause honestly no rotary shops are ever gonna give this level of details to their customers, let alone on RUclips. Just keep doing you Rob and share what else you know on the engine, looking forward to the firing up on the 12 rotor!!! ❤

    19:21 a potential solution would be to either have bolts, bolting it down to the aluminium all the way around the inner lip, machined flat with the item installed and sunk from the face by a fraction of a mm. The rotor shouldn't care. OR an intermediate plate that sits on the inside of the aluminium, is bolted and has a machined thread that accepts a ring, which itself is threaded and meant to suck the plate in.

    You're right in that the first thing I thought when I heard about this engine was, "How do you remove all that heat?". And, since I want to see this thing powering a classic Chevy muscle car, I'm still asking that question.

    Rob,
    I know you have dial indicator. Not trying to tell you to do anything, but I would mount a mag-base. Then you can see how much spring you get back.
    Seriously brother. I cant wait to see this motor run. If there is anyone that can do this, it has to be you. Great job explaining everything. To be as 100% technically correct, and bring it to layman's terms.
    GOOD LUCK!!!

  • @0to100_RealQuick

    For the oil draining issue for the center rotor, could you have a timed valve that would alternate and let each side alternate vacuum to pull the oil? The valve could even be incorporated into the bronze air screens on the top of the left and right rotors. Love your videos.

    A 24 rotor powered boat would be incredible. Even if each rotor only managed 110hp the boat would make as much as 6 mercury 450Rs with probably 1/3 the weight.

    An interesting way to look at the way that eshaft is setup would be much like batteries, 2x2 rotors in parallel with 2 in series, or 4 rotors in series like the 4 rotor.

    Rob - with the gearing that drives all 3 rows of rotors. Set the centre gear to zero degrees and also the set the gear which is driven by the idler gear to zero degree. With the gear which is half a tooth out (or 3 degree as you say) modify the inside of the Original gear so it sits on the inside of a stub which has a bolt pattern joining both parts together and that is also slotted (a little like slotting cam sprockets).
    This will allow you to index your rotor shaft to zero deg and help you hide the 3 deg timing run out you have found in the gearing.
    Hope the above makes sense and may be of some use to you. Very informative videos and love to watch them 😎👍. Dave.

    As for your bearing issue, tapered roller bearings might be a solution? The can take axial loads, and skf generally makes them with high enough max rpm ratings (though I don’t know if they have the exact size you need).
