How to secure drill motors?

Hi

could someone tell me the best way to secure drill mototrs to the base? but it cant be anything big i have limited space

cheers alex

Hi alex.

there are 2 drill mounts that i know of. Theres doms and the Robo Challenge ones that we do. i can send you an email with some specs and pics on if you like.

cheers
James
Robo Challenge

i sell doms mounts at £8 per pair

yeh james c could you email me, coul;d you give some more info on the ones you sell james b

thanks alex

Just take the housing the drill motors come in, drill a couple of holes in the bottom and bolt them down with 4 mm bolts. A third bolt through the side of the plastic housing will stop it from wobbling. If you use the drill casing as your mount it saves money and gives you armour around your motors.

could i use something like http://www.active-robots.com/products/motorsandwheels/easy-roller.shtmlhttp://www.active-robots.com/product...-roller.shtml? (right at the bottom)


thanks alex

As Ive told you on email Alex if you can make something like that up yourself go for it (though rear support on the motor would also be advisable).

If youre looking for a premade solution check out the mounts Robo Challenge offer, theyre nice and robust single-piece units that are very compact, ideal for your needs most likely.

they are cncd plastic mounts for the front of the gearbox and rear of the motor. The plastic is fairly soft, so doesnt break.
They work really well at absorbing the shocks to the drive.
The steel ones on that website will bend and jam up your wheels, if you weld cross braces to stop this, they will be too stiff and youll break the drills.
Up to you, but I strongly recommend either plastic mounts, or soft bouncy wheels, to keep your drills in one piece when you get flipped or hit.

Haveing made many mounts for drill motors and out of many different materials we found that it all depends on where the motor is supported as to how it will cope with impacts. at the end of the day drill motors are made very cheaply so if you get hit by little spinner the force is so great that it would be better to put a sturdy mount in that will support your motor at the right points. soft mounts will flex a little which will then try and bend the motor/gearbox. As its the motor thats keeping the mount in place rather than the mount solidly supporting the motor. In all cases its best to use as soft a wheel as possible or rubber mount the drill mounts. This way the mount will absorb the shock but wont let the motor take the strain.

can you send me some info on the ones you do james c thanks alex

Please send me info too James,I need some mounts :)

i dont wnow if you havent yet been able to send the pics and specs on the mounts to me james, but i dont seem to have them?

thanks alex

James has been working for the last few days and more an likely hasnt had access to his computer. I will be talking to him today so I will ask him to get some pictures for you.

thanks, thought it might be down to something like that

cheers

Alex, sorry about the delay - James is snowbaording in the Alps at the moment so he hasnt been on the computer for a bit now.

I have attached a picture of the mounts on my profile, very simple to understand. If i remeber correctly i think the threads attached to them are 60mm apart. I will double check later and give you more info if you need.

image wont upload, ill just e-mail it you tonight.

Grant Im interested , send me the picture as well

Im also interested, so could I possibly ditto Alis request please?

Cheers :)

I am also interested, could you please send me the pictures as well

thanks

Will

Grant, There is now a size limit of 800x600 pixels for profile pictures, to save disk space.

Im also interested.Cotld you send it to me aswell please?
Sorry for any inconvinience :S

see my profile for pic of my mounts.
Ive never had a motor break using these, or gearbox, other than through putting too much power through and breaking the gears.

all i can say is beauty has these james I had no problems untill mario got his hands on beauty :)

i have broken 6 g/boxes in the last 8 fights

Johnno an I think my problems the ram fireing so i blame Mario but we are working on it daily!!

together we will get there or goto bosches

hi john,
can i offer 2 suggestions to help preserve your gearboxes, I assume it is the plastic rear plate on the gearbox that holds the motor on that is your problem??

1- use a second, or move your current, large hole mount (the one for the rear of the motor) to the other side of the ferrite ring (you need to slide this off the motor and replace later) which gives more support at this point. use screww/bolts and thin ali or steel tube as a long washer to brace this area for extra rigidity.

2- drill holes in your wheels tire. assuming they are solid rubber, putting holes across the tread creates squishy spokes in the rubber. these can be tuned with a little trial and error to give support running normally, but under the high loads of flipping, will deform and allow your chassis to rest on the ground, taking the loads away from your gearbox.

hope this helps
james

hmm well its on 10mm poly floor atm and ive moved the second mount where johnos just bolts a perspex 10mm plate on to gear box as i say we wre working on it

the metal 3 prong bit keeps snapping and locks g/box up but in for another test tom at Robots live

Hi James b

could you give the dimensions of the motor mounts that you sell,

cheers alex

John, Beauty came a long way. And youll keep upgrading her untill nothing breaks anymore.

From a bufferless 25mm bore ram to a buffered 60mm bore ram.... (not a ram build by me, but by Inventor)
That means you came from 250 kg of slow force to 1412 kg of faster action. And that all for less weigth.
I wonder why things break?

Mario beauty2 is only half made

but yes all your fault :)

ps shes good now :)
