Wheelchair motors

**Anttazz** · 26th March 2011, 16:42

I'm trying to remove the shaft from an old set of wheelchair motors to take the mount that fits onto the robot perfectly and attach it to a new set of motors Jonny kindly sold me. I'm a bit stuck with this, has anyone any idea as to how I should do it?

Your trying to remove the wheel from the shaft of an old set of wheelchair motors?

OR from the gearbox of an old set of wheelchair motors?

I'll get some photos up soon to try to help me explain. The shaft seems to be holding on the mounting plate so I was trying to remove it or remove part of it to get the the plate. It looks to me as though it would simple screw on to the new motors.

As promised, some photos to help explain what I mean.

Motor on the right has the mount on it, left one does not but I want to change it onto that one.

You want the silver plate off?

Looks like the bearing will need to slide up the shaft.

Clean the shaft remove all rust ,dings and burrs then lightly oil..

It might be possible to just lever it off.

Failing that it's scientific application of a big hammer.

Try and find a way to support behind the silver plate ...e.g. across some open vice jaws.

If you don't want to damage the shaft place a lump of Ali on the shaft end and hit with big hammer....

You might need another pair of hands to support the motor whilst whacking the shaft.

Yeah its the silver plate I am trying to get off.

I will give it a bash (no pun intended) and get back to you on it.

Thanks Woody

Another problem I have noticed is that the shaft on the new motors is considerably wider than that of the old motors. Is there any way to change these over and just use the whole output shaft of the old motor in the new one? The gearboxes are roughly the same size, maybe I just have to take that larger shaft off of the new motor somehow and it will be the same as the old motors, is that likely?

Sorry for the vague questions, I realise they may be almost impossible to answer or even understand
