never take this video off TH-cam as i need it for when i get the money and start the build on a rc tank of the 1/10 scale also plus its educational as well
Thanks for the excellent video...just a question..when it comes to speed calculations, its clear but when it comes to torque, while turning, we have a torque from the axle (i.,e) blue sun gear which drives the planet gear and also a torque on the planet carrier (from the steering motor) which drives the violet satellite gear, so we have two torques propelling the violet satellite gear(one from planet of blue sun gear & another from planet carrier) so what will be the torque on green shaft?
N0: velocity of the engine N1, N2: velocities of the green output shafts For a car differential: 2*N0 = N1 + N2 T0: power of the engine T1, T2: powers on the green output shafts If the losses due to friction are ignored, the relation between the torques is: T0*N0 = T1*N1 + T2*N2
Hi. Nice video. May I ask a question? Motor M, the pink one, how much power is required here relative to the main motor. One minute I think it only needs to overcome the friction in the drive train, than, once I think I have it, I begin to believe that it needs a significant amount of power. Thank you for the help,
Nice design. couple of questions though, the drive torque output is equal on the steering planetary gears housing? Meaning, the steering planetary gears housing will not rotate in the event if drive input / output torque increases. and incase of drive input stationary, does the steering when it on move motion will rotate the drive input? I've been searching for a while for a double diff steering design that will cancel / equalize the torque on the steering input. As you know, regular double diff steering will force the steering input to rotate incase of torque increased, which can be fixed by worm gear steering on the diff housing, which is not practical. Thanks.
thanks for the great video, do you have any recommendations on where i can learn how to analyse the speed and power outputs of each shaft? basically i am trying to calculate what kind of power i need the steering motor to have when compared to the engine i.e how does the ratio of power between the main motor and steering motor effect turning?
@donza W did you find any lead on finding the power of motors for the shafts? For one shaft I am using engine as input while I just need the details for motor which I am unable to find up till now. If you find and update on it do let me know here.
@@muhammadhamza5702 I haven't as of yet done any calculations, I think it's possible to use kinematics to make a free body diagram of the gear system, then use some more kinematics to determine the effect on the steering radius.its a pretty complex question, but based on a uni course I did I think it's possible, it's worth looking into machine dynamics. I'm actually making a 3d printed model of this gear system for an remote control tank, might be able to calculate it from that.
1. In the Assembly file, assemble the two gears onto their bearings using the Insert tool. Each gear must have a sketch of its pitch circle. 2. In Environments, Dynamic Simulation, Insert Joint: set joint “Rolling: Cylinder on Cylinder” between the two gears by clicking on their pitch circles. 3. In Standard Joints, click the mouse right button on Revolution of the driving gear, click on Properties and assign motion to the driving gear. 4. In Simulation Player click Run
So how are the green gears stopping or how could I make them stop? I'm trying to design a chassis for a robot by using only one motor and could really use the help
If engine is rear, for turn left, "M" must be can change rotation direction. That is problem, if engine "M" is mechanical. I think that have electro motor and mechanical engine. Electro motor must be have so many force, but for brushless motor that is not problem.
Yeahhhhhh my invention would cost too much to make it work. I thought it'd be more simple until I drew a sketch and did some research. Back to the drawing board.
罗梦宇 yup I have tank project too and I used 2 motors in pair of sprocket and I used two motor speed controller and I'm planning to make h bridge circuit using 2 relay
Cela s'appelle des différentiels asservis....... inversion du sens de rotation sans perte de puissance, sans usure, sans friction...... connu depuis 150 ans..... sorry my writting!!...
This has the clearest explanation of how this system works. Thanks very much. I’ve subscribed.
Me too
That is a lot of work there. Thanks for sharing.

Ya it helped me a lot in designing a tank drive system.
So have you looked into the Voith-Schneider propeller system yet? It would be interesting to see how it works in a computer simulation.
I will try.
Please see

Thank you for your request.
Thank you sir for taking the time to make this video! Much appreciated!

N0: velocity of the engine
N1, N2: velocities of the green output shafts
For a car differential:
2*N0 = N1 + N2
T0: power of the engine
T1, T2: powers on the green output shafts
If the losses due to friction are ignored, the relation between the torques is:
T0*N0 = T1*N1 + T2*N2
@@thang010146 Thank you
Thank you. Very good animation. :)
Just confirming: The 2 yellow spur gears are of unequal size? So they acheive the same ratio with the respective annulus?
Numbers of yellow spur gears: 16 and 20.
Number of annulus gears: 64 and 80.

Sorry, I don't have the information you need.
Nice animation! What would power the yellow gears though?
Motor M.
Should we use a warm gear under the M motor if we don't want different surfaces under each side to cause a turn unexpectedly?
Yes. Thank you for a good suggestion.
I think this could give a smooth turn curve on road. like the output of differential.

Sorry, I don't have the answer. Because it takes a lot of time to study the problem.
It's called the Gleasman system.

Very good video.
I count 21 gears total, is that correct? Man how complicated just for steering!
Yes. It is for steering vehicles of continuous tracks.
I haven't seen a simpler mechanism.
What should I do if I want to operate the gear in Autodesk Inventor?
1. In the Assembly file, assemble the two gears onto their bearings using the Insert tool. Each gear must have a sketch of its pitch circle.
2. In Environments, Dynamic Simulation, Insert Joint: set joint “Rolling: Cylinder on Cylinder” between the two gears by clicking on their pitch circles.

Two brakes are needed.
One for the for the blue shaft, one for the yellow shaft.
Or
Two for both green shafts.
Nice👏👏
¿What would be the power of the orange motor with respect to that of the drive motor?
It's smaller but I don't know how much.
It must be determined by calculation.
I built one of these with meccano a few years ago
What would M be then?
Steering motor
What software is this with?
Love the content
It's Autodesk Inventor.
If engine is rear, for turn left, "M" must be can change rotation direction. That is problem, if engine "M" is mechanical. I think that have electro motor and mechanical engine. Electro motor must be have so many force, but for brushless motor that is not problem.
Yes, M is an electric or hydraulic motor that can change rotary direction.

Wow

Hydrostatic drives suffer from low top speed and mechanical efficiency.
How to build a tank!
罗梦宇 RC tank or real size battle tank???
This is too complicated for an RC model tank and over-simplified for a real tank.
