Im doing a project for one on my classes anaylizing the winch on a tow truck. We are using the Ramsey DC-200 RamLock. It has a couple gears in it and we need the tooth counts. We called Ramsey and they wont give us the information. Does anyone know of a source for this info?
Thanks Casey
 
count them?
 
Being worm drive and planetary reduction ( to the tune of 470:1 ) you'd be good to tear down and do some tooth counting, maybe even consider the pitch of the worm gear teeth and such. Oh, don't forget motor RPM while yer at it ;)
 
We have the worm gear and one of the other gears on hand but we dont have the other three gears or I would just count them. Also we couldnt find the horsepower of that exact motor but from other ones they all had 4.5 hp. Does that seem reasonable?

Also we are looking at the motor. I understand the basic concept of an electric motor but can anyone give more insite on how it works. What exactly does the solenoid do?
Thanks Casey
 
Just what sort of class is this ? and the basis/scope of the project ?

It's not that I don't wanna help, but maybe you should do your homework ?
 
Maybe I mislead you but I have done research on it and Im still not completely sure how it works. I was just looking for some first hand experience on winches being that I have never used one or messed with one.
It is a mechanical design mechanical engineering class. We are looking at the forces in the winch and forces in the cable. We are looking how the electrical power is converted to mechanical work and the gearing it uses.
Im a senior and Im not looking for the easy way out just trying to ask someone who had more knowledge of the subject than I do.
 
Uh.... how the fawk did you get to be a senior in the ME program if you don't know how an electric motor works? Did you take Rocks for Jock 1001 rather than physics? How's that happen?
 
To be honest, to answer all of your questions would take a long time. It's not as simple as a two or three sentence answer. To be honest, it's more of a very long term paper if not a book.
I will answer one of the simple questions though.
What is a solenoid?
A solenoid is simply a electro magnetic relay. It has continuous power to it. It is activated by another power source that is switch activated. When activated, the electro magnet raises a piece of metal(usually copper) to make contact with the constant power source. It will also contact the opposite side of the relay, sending power to the device( ie the winch motor, lights, or anything electronic device). A winch solenoid is as said before, a relay. Very much like the one for your starter.
Hope this helps
 
Isn't the ME program the same one that does the mini-baja and the other little racecar?

Anyone else ever build a very basic electric motor with a nail, some wire, and a magnet? We did it in my 6th grade science class, man that was fun..
 
We built an electro-magnet that way in grade school. How did you get a motor out of that. And yes I Know how a motor works.:shaking:

oh wait we used a battery not a magnet.

Click to expand...

As I remember, when we had the fixed magnets near the windings and gave the nail a kick start, it would keep rotating.. it had some sort of crude brush system...

I'm surprised you know how a nail works, Greg.. :flipoff2:
