-mounted Bevel gear on the drive shaft can remove this problem too to.

and for synchronizing the belt whit out teeth doesn't need to it . our if small gear be able terne around itself a little bit (10 degrees) whit carve and small bumpy shape teeth
become solved the problems.

and for arms bending problem. It has tow solution whit antenna piston we can attach idlers center point to the mine shaft it doses limit it of the maximum increasing. But batter solution is vertical beam attached next to the arms they can slide between beam gap exactly.

Great visualization of not working transmission.

The arms with no contact would extend with the remaining oil pressure and the arms with contact would retract. Unless you put a solenoid valve on eache of the arms. Centrifugal forces would cause cavitation in your hydraulic fluid at higher rpms.

I like the core idea though.

The number one problem I see right off is, the driven pulley consisting of six little cogs is not round. You have a hexagon shaped pulley with rounded corners but overall it is not round. Vibration would be tremendous. I think the animation is great however. Nice job!

someone missed a few classes in Mech 101.

The input shaft and output shaft are constantly moving to and from each other as the planetary side expands and contracts. This means another gear set or cv joint is needed to give a fixed input/output.

0:21 ... just pulling some teeth from the rubber belt, it moves faster than the gears ...

[shredder]

We already tried tried this setup 2 years ago. It doesn't work properly on high speeds as the belt tends to vibrate extensively.

The tension on the tapered wheel hub will pressure one side of the star drive and lose the center by pulling on one direction, elliptical center, or center will have off center axis as hub wheel expands

[FlippDurch]

This is just a complex and heavy version of something every scooter has already. Also the different axle distance with different gearings seems unpractical.

No sé quién se le ocurre estas cosas fantásticas. Muy bueno

[Mroll]

idea works only on PC. all see in first second that belt don´t go on teeth correctly

[FrekkTime]

Надежность системы стремиться к нулю, а цена будет как у самолета.

Each of the small gears needs to be mounted on a worm gear that automatically rotates the small gear slightly to keep the teeth of the gear lined up with the cogs on the belt. As the arms extend, the worm gear will rotate the teeth on small gears, that way the belt doesn't skip.

no veo la aplicación practica si la polea que debe ser fija tiene que desplazar su eje hacia adelante en un avance a medida que la polea variable de agranda

The DAF variomatic solution is simpler and works perfectly.

А как быть с теми гидроцилиндрами, ролики которых не нагруженны веткой ремня? Давление жидкости будет стремится выдавить их на большее расстояние, чем те, которые нагруженны ремнем.

Чем сложнее конструкция, тем больше она ламучая.

[geo]

This is perfectly possible. A great practical idea. Enough angular play is necessary for idle rigid sprokets, but it is not shown in the animation.

[ebarbie]

The only solution to continues variable trans is no transmission at all. Just use a good electric motor with proper speed and torque control instead...
