Mechanical Brakes

that looks like a good idea, id like one as well if he makes some ,lmk , if not i could use some aluminum and make a spacer to allow me to gear back to a 16 tooth pinion or smaller , which gives me better motor temps


thanks

heres one more pic to show the clearence



ill have to get a measurement on the thickness of the adapter, to clear the brake pad bolts, and then use a long shaft pinion

I got a response from Mike today. He said he would try and make a couple of the spacers I posted sometime this week. It should be pretty easy for him to do with just a couple tweeks to his program for the front motor cover.

I'll post up some pictures when I get it and install it.

sounds great, if it would fit the motor i have id take one as well, but i dont plan on running this motor forever, just need some $$$$$$$$

[jhautz]

It should fit any motor that has a standard bolt pattern. If its the 9xl you are running it will fit.

Just send Mike a note and tell him you want one of the motor spacers he is making for Jeff. I'm sure its no sweat to make another one once he is set up and machining them.

ok i just sent mike an email....

i mocked up to check .... and it should work sweet, i used spacers i had and i think its about 4mm thick so that is right, and i will have to dremal a very little on the outside brake pad (1mm) and will also trim a small amount off the heatsink/motor clamp to ensure the brake disk wont hit .. heres some pics from my mockup, oh and i have plenty of shaft for pinion mounting, i used a 15 tooth in mockup but i should be able to use less as well

Could Mike possibly add the 4mm to the front of the heatsink/motor clamp during machining? That would take care of two problems at the same time, and you could free up a mm or so by combining the two. That would maximize the motor shaft available length. Just a thought...

[jhautz]

Yea linc. That would work for sure, but I dont think Mike makes those motor heat sinks in house any more and changing a big part like that is sure to be alot harder to do than just making the simple adapter plate, but its definitly worth asking him about if you want it.

I personally am not planning to use a motor that requires an clamp/heatsink so it woulnt work for me.

Entjoles, The plate I asked him to make for me was thicker than 4mm. I think I will need 6.35mm (1/4") to clear the whole brake mechanism. Thats what I asked him to make for me.

ok thanks, ill shot him another email

i also trimmed off part of the hs/clamp and got lots of room

it will accept a 14 that i have and maybe a 13 if i dremal the brake pad plate

so i could just use a neu adapter plate with part of it cut off right?

this is the size i will need when i get a diff. motor w/o the heatsink clamp

my 4mm + the hs.clamp of 2mm = pretty close to what you came up with

i wish i had a caliper

I used a spacer for a while, but it was a hassle to line up the spacer, motor and mounting holes. I glued the spacer to the motor to hold it but the glue never held for long. If you can get Mike to add a few milimeters to his mounts or the heatsink that would be prefect. Another idea I had was making a spacer, and using the unused holes on the motor you could bolt it to the motor. If you countersink the holes and use short screws you should be able to use the extra holes on the motor can to secure the spacer to the motor, basically making it one piece. I will dig out my old spacer and try it out.

Thats a cool little part to allow mechanical brakes. I'm just afraid that the shaft wouldn't stick out far enough for the pinion gear...

[jhautz]

With the Neu motors there is no problem at all, they have unusually long shafts. The Lehners and Feigaos are starting to get to the end of the shaft, but its no problem. The shaft on my 1940 doesn't quite stick out the other side of the pinion gear, but it in there plenty that there should be no problem.

Could you possibly flip the CD around? Or would that make the spur too close?

I think he us using the tekno clutch thingy on this xray. It would fit fine the other way around, using a std pinion.
