3D PRINTED DIFFERENTIAL TRANSMISSION FOR RC CAR | HOW A SIMPLE DIFFERENTIAL TRANSMISSION WORKS ??

Ok, these are the parts which i have removed from the base and done a bit of sanding and polishing for the smooth movement of the gears, so let’s check each part individually. So this is the side gear. This is the gear onto which is the transmission, or the power from the gearbox is delivered with the help of a shaft. This is the shaft and, kao što možete vidjeti, the hall here is printed in a square format, so we can very easily lock the shaft into this hole and transfer the power very smoothly to the differential system. This is the ring gear. Kao što možete vidjeti, there is a ring around this gear. We are going to place four gears inside this ring which work as the differential mechanism. These are the four gears which we are going to place Music inside this ring. Two of them are called carrier gears. So these are the carrier gears. These are the two pinion case, so these four gears, which we are going to place in a cross alignment format inside this ring gear before that let’s check how the principle of differential mechanism work. Kao što možete vidjeti, these two gears, the side gear and the ring gear, it has got a very smooth surface, that is the height of the teeth height and the width of the teeth is very small compared to the other set of gears. So when it is connected, when these gears are connected in a relative motion, the priority of movement or the ease of movement will be always to this smooth.

Yes, this small, deep small and large number of teeth compared to this one, which are small in number and the teeth is deep. So the this movement or the gear of the movement of the gear will start only if the movement of the ring gets blocked. When the ring get blocked, when there is no way out these gears came into action, i can demonstrate it, but i will demonstrate it once the assembly is complete, so let’s start with the assembly. First of all, we have to place it to carrier vs. Along this side. I have 3d printed shaft for the side, gas, also, but being so small, small, tiny in size. This was not proven to be effective, so i have to cut out some shafts with the help of these pins, Ok, friends. So our gears are in place. We were planning to fix this gears with the help of two pins independent pins, but it was not successful and i wasn’t able to place it firmly onto position. So there is a small change of plan. I just inserted an m2 screw with its heads removed and made a series connection between these two gears, because the gears which are here we are going to place it perpendicular to these two gears are not connected to each other. They are guided by independent shafts. So the track is clear, so just plan to place a single shaft so that the connection is more secure.

So just continue with the assembly. Hajde. First of all, let’s insert the side gear and glue it up here is inserted let’s glue it up Music. We need to close this yes carefully, because if the idol zip touches between the gear and the case, then the gear will get sticked into the bay in the box. For the case, and for that it will be very difficult to remove because we are using a super strong glue to fix it. So let’s drop a few drops of glue here with the help of some pointers. Let it dry Music, so side here is fixed. Now let’s place the ring here and complete the assembly with the help of this connecting rods. Kao što možete vidjeti, it just eases into position. Music let’s complete the assembly just by placing these gears into position and clocking, it fix it permanently with the help of glue. Kao što možete vidjeti, the glue is very carefully dropped into the shaft head so that you won’t touch now mistakes or no spill of glue. Ok, now just wait for a few seconds so that the glue of this shaft will dried up quickly, because we need to invert the gearbox for the case and if the glue is not set completely, may drop down and spoil our whole assembly. So just wait for few seconds. Ok, i think the glue is set so now now let’s place the other gear and complete the differential assembly.

So you can see this here is Music with the help for some glue. Usually, this glue is only doing the job of securing the position of the shaft so very little glue and also do the job good friends. The assembly of our differential system is almost complete. The only thing left is to place the cover of the case and seal. The assembly before that let’s check how it is working see this is the road which is being connected to the drive shaft from the gearbox, and these are the rods going towards the axle going from the axle towards the tires it’s going to go to one time And this one go to the other time so once the driveshaft is powered, so this is how it works first, as a driveshaft rotates. Both these shafts will rotate let’s, see what happens if one of our wheels gets stuck mud or some hard object. In that case, the total power will be transferred to the other wheel, and the shaft will rotate the other side same with this side. Također, the ears are too small need a bit of wear and tear and polishing to work it smoothly, and the material is also pla. Unlike the metal, the edges are not that much sharp that’s. Why it’s getting stuck that’s, not an issue? It will become battery smooth as it rotates for some time. For an example, you can see this one it’s a miniature version of the same differential, gearbox, it’s working so smoothly without any problem.

So you can see the inner yes as well as the outer gears are working without any problem, so this one, which i have completed for my rc car, will also get smooth as it rotates for some time so that’s all for today guys. So this is a gap of our differential and it’s ready to go to a rc car. This driveshaft from the gearbox connected to this end and the axle being mounted to both the sides.
