Cim-u-lator Gearbox

[Feroz1325]

Our team is thinking of direct driving a 2 of these gearboxes (powered by 775-18V) on 2 wheels to get a two wheel (horizontal plane) shooter. However we are trying to find some CAD drawings or measurements or even pictures!
Does anyone have CAD drawings of these gearboxes?
PS: On a side note, if anyone has any previous experience with the CIM-u-later gearboxes and want to share them....all opinions are welcome .
Thanks!

See attached CIM-U-LATOR photos.

I really don't know what Banebots is thinking. It has been out there a year and still know photos on their website. I am confident they'd sell many more if folks could see what they look like.

There is a lot to like about these little guys.

I purchased both versions from Banebots this past fall. I also purchased the AndyMark CIM-sim.

There is a lot to like about the CIM-sim too.

Things not to like too (e.g. I don't like AndyMark's use of clinch studs -- one came out in the sample I purchased. I don't like the low 2.7:1 ratio on the CIM-U-LATOR I don't like that both block the vent holes on the front of the motor - but lots of folks do this, including my own dang self often in the past).

I have just uploaded a bunch of photos of both these gearboxes to Dropbox -- here is a link to the gallery

Good luck.

Does anyone know if you can mount RS-550's on the CIM-Sim's as well? It says series 500 motors, but I do not want to assume.

Thank you so much CD-community!!! You guys rock!
I was just wondering...from the CAD and pictures it seems as if the output shaft isnt keyed! Can someone please confirm or deny this?
Also the 2.7:1 ratio might be good for this years shooter, more rpm under equal compression should equal a higher distance.
Again Thanks!!!

The output shaft is definitely keyed. As it turns out, all my blurry pathetic pictures don't show it very well. You can barely see it in one picture in the gallery though -- attached.

Dr.Joe your pictures are nowhere near pathetic....seeing as before your pictures my team and I had no idea what the CIM-U-LATOR looked like (our teacher sponsor even thought it was a scam ). Thank you very much, how has your experience with the gearboxes been? Any hints, pointers or things to look out for?

I haven't put them to use as I found a way to do what I want without them. I've never put power to them.

And yet, they have a surprisingly high quality feel to them. I think that for what they do, they are could be pretty good.

Cim-u-lator (550 comments),

I used the Banebots $30 coupon to offset the of purchase 2 - 550 motors and the 550 cim-u-lator gearbox. I hand assembled the unit and thought it went together well.

If you are planning on using 2 motors in your Cim-u-lator like I had planned you should be aware that you are missing some components. You will need a 2nd pinion gear that Banebots sells (PN missng here) as well as 2 small machine screws and lock washers (PN??) to mount the unit. The unit comes equipped to mount just one motor.

If I had to do it again, I might have used my Bane Bucks to get the 775 Cimulator and a 775 18 volt rated motor and try to use this configuration in a belt driven application for the shooter which would keep all 4 CIM motors available for traction/propulsion

Joe,

Do you have an opinion on the quality of the Cim-sim?
It has bad reviews on AM and I am mostly just curious.

We received a 500-type CIM-U-LATOR today in the mail, and I took a few pictures.

So far I really like it, according to my calculations based on the RS550 spec sheet, it should have an rpm of 7100 and a stall torque of 370 oz-in.
Compare to the CIM motor's 5310 rpm and 340 oz-in of torque.

Only downfall I see is that it requires two motor controllers.

Anyway, my two cents.

We have had some trouble with a dual CIM-u-lator using 2 550s. For some reason the motors overheat extremely fast. We mounted this on our test shooter and instantly had smoke coming out of them. The only way we could run them was to put the big cooling fan blowing down on top. Even with that, the motors toasted after some test runs and case shorted.

Have you had any success with yours?

We have decided to stick with the single CIM-u-lator using the 775-18V with cooling. The final design will have cooling fins installed on the motor.
