A gear with Brusshless engines, Genuine outdoor gear and ine

[Edwin]

After I've got a couple questions about my drives and even a King Tiger tank build, for which I am just starting with the gear, I make a small building report it.

I build my bathtub always drives a brushless and with my larger pans and the performance of up to 450W per motor matched with functional outdoor gear transmissions. In this tank I build even further momentum masses which give a very realistic driving behavior of the vehicle as it can no electronics.

The gear cheeks and the outer housing of the gear I have previously milled

The gears of this are already there.

But first I build the engines. In both the drive shaft has at the other side.

http://up.picr.de/14828166ar.jpg

So that they are not ready yet. I still need the flywheels on the motors. These I cut two slices of a steel rod.

http://up.picr.de/14828167vq.jpg

These disks do I have to work on the lathe so that I get two identical and exactly matching the engines flywheels.

So I had to just shrink to the motors and gluing and so this siend now ready for installation.

Once I was at a meeting yesterday, it is today with the installation of the transmission cheeks further. First, the spacers for the cheeks of the two sides gear and let's see how they fit inside.

http://up.picr.de/14861037oa.jpg

Then there were the spacers between the gears and the fit of the cheeks in the corners, but then it sits.

http://up.picr.de/14861038lr.jpg

Then I busy myself with the first countershaft housings. Since I had a 30 times M1, 2 threads cut into the aluminum. A proper detention....

http://up.picr.de/14861039fu.jpg

Eventually this was done and then I could adjust the countershaft. By this, the transmission is so screwed to the inside of the tub and connected thereto.

http://up.picr.de/14861040xz.jpg

http://up.picr.de/14861041ov.jpg

So I get an absolutely stable and can withstand the forces of the stem and can transmit.

[Edwin]

Now that I completed the whole gearbox I can slowly build the proper gear and since I first screwed the two motors in the frame.

http://up.picr.de/14908205eg.jpg

Now I can successively build the individual gear stages. for the first two gears must be connected to a shaft. This requires the small sprocket strength on the axis drill out.

http://up.picr.de/14908206hr.jpg

I have to edit virtually anyway with my gears all gears before I compose a gear.
After soldering and cleaning the first stage now siht like that.

http://up.picr.de/14908207ep.jpg

and I can also install immediately and check for smooth operation.

http://up.picr.de/14908208yf.jpg

For the next steps I must first sleeving the larger gearwheels, so they fit on the waves. I drill them first to something bigger and then stick a brass insert into the hole because I turn off at the ends.

http://up.picr.de/14908209ue.jpg

http://up.picr.de/14908210gk.jpg

To get a clean round running gear I use a sharpened by me for brass drill, I then just zustelle in speed when drilling in that the metal comes out of the hole in spirals. How to access a virtually non-extending bore and about running gears
http://up.picr.de/14908214kn.jpg

http://up.picr.de/14908211ay.jpg

Now I have the holes and threads for two M3 set screws attach each only with the larger gears.

http://up.picr.de/14908212sm.jpg

The pinions of this stage are brazed already there because of the high torque, as solder may loosen and here is the final stage.

http://up.picr.de/14908213sm.jpg

http://up.picr.de/14908215rq.jpg

[Edwin]

And on it goes to the transmission.
I could now as I had already adapted into the tub and put the same even use the ball bearings in the countershaft.

http://up.picr.de/14918516jw.jpg

Now I can adjust the countershaft. In addition I have put the gears into the housing and nu see the supernatants.

http://up.picr.de/14918517cx.jpg

I rotate the pinion gear at first, so that the gear wheels fit into each other congruently.

http://up.picr.de/14918518kl.jpg

Now I have to solder the pinion still hard with the connecting shaft from the inner to the countershaft gear. The high torque make it necessary.

http://up.picr.de/14918523pw.jpg

http://up.picr.de/14918520sb.jpg

http://up.picr.de/14918521ch.jpg

Then the large output gear was adjusted. This holds also later found the drive axle in the countershaft.

Today we went first with the guide wheels on, so I can also set the track chain, especially at the drive wheels.

For this I must first make two axes, since the originals are soft iron and China have only 3mm.

I use 4mm silver steel.

http://up.picr.de/14944280qz.jpg

The stop I'm easily in the washer do I solder a little hard. I stretch to the axis standing in a vise, spend some flux and put the silver disc and a small section in the middle.

http://up.picr.de/14944276pj.jpg

That one must then only with a gas flame to heat up the solder melts and runs clean.

http://up.picr.de/14944277gt.jpg

After brushing, so I have two suitable axes and I can mount the idlers.

http://up.picr.de/14944278iy.jpg

http://up.picr.de/14944279vo.jpg

Then it's back to the drive axles on. The build is woder hardest part of the tub.
The axles do I feature 8mm silver steel I first ablänge plan and turn. Then comes in each axis at one end I cut a hole in the M4 thread.

http://up.picr.de/14944282fi.jpg

Thus, the drive wheels will fit on the axles I milled a flat on each.

http://up.picr.de/14944283cc.jpg

http://up.picr.de/14944285dw.jpg

Now I can stick the axle with a sprocket mounted to the bearing and align with the chain launched.

http://up.picr.de/14944284mn.jpg

http://up.picr.de/14944286ub.jpg

The position of the output gear I makiere loop and the point on the axis. In addition, I filed the hole of star-shaped.

http://up.picr.de/14944287rx.jpg

http://up.picr.de/14944288xd.jpg

http://up.picr.de/14944289nb.jpg

Provided with some flux I now address the axle and the gear on a fireproof surface from each other.

http://up.picr.de/14944290hl.jpg

So I can then solder the parts hard.

http://up.picr.de/14944291ld.jpg

After brushing, I now have a perfectly stable connection to the axle and gear.

Since I'm at the Experts' in Mainz at the weekend I also take there before the tub. That's why I'm doing for the sake of clarity only one side of the drive ready now and let the other countershaft still open.

In the page that I set finished, I fill the counter first with graphite grease and insert into the drive shaft so that the fat completely fills the housing behind the gear.

http://up.picr.de/14978676tn.jpg

At the front I cross the Overflowing fat back to the counter and fill it as far as it is possible to also. How do I stop without further seals the ingress of dirt and water. It works I could only see recently with my Panther. After several hours of running the filling was still ok. I then screw the cover to seal sufficient mass to well be anywhere.

http://up.picr.de/14978677ww.jpg

After cleaning, I have an extremely stable axis and a durable, maintenance-free reduction.

http://up.picr.de/14978678gt.jpg

Now I have only installed the chain and the Experts' can come.

A master at work, you must have one really nice workshop setup

[Edwin]

And on it goes.

Today was the first show after the second countershaft turn.
I have really nice again filled with grease and screwed the lid with sealing compound.

at the drive wheels I had to unscrew the screws on the back of imitations. It is supposed to block anything since later and can damage them. One can see them anyway when installed not.

After I installed everything I could install the electronics for a test drive. Here I am just programming the controller.

Then of course was a test drive ausgibige turn.

Since the pan is too easy, the suspension is a little too high and the necklace is a bit long, but otherwise everything was to my satisfaction.

Now it can go with other things at the sink further

Hu Edwin,
Simply stunning workmanship .....and I think that your 'No Electronics' method of inertia is by far the best idea
A 70 Ton tank weighs 70 Tons.....whether it is on a road, mud , grass or sand so it is perfect that the inertia is always present.
Keep up the good work

[Edwin]

Hi Dietrich,

yes, my method of mechanical inertia corresponds exactly to the behavior of an original can be registered that way. Some have to report the drive with their vehicle relearn and forced it to move, as the tanks were really as heavy as a large, especially on smooth surfaces because my laziness always adapts to the ground.....

I was at my time as a soldier and tank driver looking therefore must look exactly like the.....
