@2testtest2 Жыл бұрын
There are free plugins for fusion for helical gears. I'm not sure they would be a good fit for this application though, as they also create a side load, which would case the frame and gears to flex depending on how much torque is applied, possibly causing them to disengage in flight. By involute gears I'm assuming you mean straight cut gears? Involute gears can be straight or helical, and is the most common type in machinery today, and are suitable for all speed ranges.

Some things I noticed - a shorter screw in the gears could help remove the centrifugal imbalance which is impeding the gyroscopic stabilization you should be getting from the rotor mast, also adding a guide flange to both sides of your small 3D printed gear will help it maintain the interface with the larger gear and not allow it to have so much play in it. Beyond that - y'all are not only insanely clever, but also extremely good at making entertaining videos.

@lubricatedgoat Жыл бұрын
With the rotor, motor and gears all spinning on the same axis the gyroscopic forces were pretty huge. If the motor is mounted horizontally, then there would be gyroscopic forces on 3 axis. There also wouldn't be such a huge lever-arm hanging under the rotor, so the controls would be more responsive. Or maybe I'm missing something simple.

A belt and pulleys would be much lighter and more efficient at transmitting power than plastic gears
@hamhouke Жыл бұрын
I don’t know about lighter, because you add the belt. But it is a LOT more forgiving of slippage and sudden increases or decreases of motor RPM. I think they are inducing a whole lot of shock and vibration because the gear teeth will momentarily disengage when it flexes. A belt would soak up some of that difference in interface angle between the large and small pulleys. Also, when you take off, you really have to surge it to get it airborne. That is when the flex is worse and the gear slippage is the most detrimental.
@wowonice1 Жыл бұрын
@@hamhouke I think a belt would allow both pulleys to be a smaller diameter than gears for the same reduction, reducing width therefore weight, creating space between them allowing use of a smaller belt and reducing the weight of the support structure around it

@@wowonice1 Maybe, but that drive gear is pretty small already. If he made it smaller, that 22K RPM motor might burn though it due to the reduced surface area in contact with the belt. Of course, they could make the belt wider, but you would gain the weight right back. There might be enough torque with that motor to reduce the blade pulley diameter and get a bit more RPM to the rotors without bogging it down. Under load, the RPM of that motor is likely to be a lot less than 22K. I think that’s it rating if free spinning the spindle.
