Gears

[JammyONE]

I'm looking for gears that are the same as DB5 used. My robot is similar in design, I know there's gears in Technobots but I don't have a clue what to go for. The motor I'm using is Speed 900's.

Re: Gears

Gears For what drive to wheels or weapon drive?

Re: Gears

The wheels.

Re: Gears

what gear ratio are you looking for?

Re: Gears

If I knew that then I won't be asking.

Re: Gears

So what exactly are you looking for? A gear ratio? What MOD of gears to go for? Your initial question is quite vague. It wouldn't be hard for someone to assume you already know what ratio you're using based on what little information you've provided.

If it's a ratio you want to know, work out what you want to aim for in terms of top speed of your robot, then use the statistics of your drive motors to work out how fast they'll be spinning at the voltage you intend on running them at. Apply a bit of basic mathematics to calculate how much of a ratio you'll need to drop the speed of the motor to a suitable speed at the wheel. Then decide on what number of teeth your gears will need and take it from there.

Re: Gears

Go mod 1 gears and minimum ratio 6:1 ive ran 5:1 and its hard to control and not the best speed for a small arena id say 7:1 or 8:1 is a nice ratio to try. You could try a 1 stage but if your going 7 or 8:1 might want to do a simple 2 stage

Re: Gears

8:1 2 stage sound good.

Re: Gears

It really depends how big wheels you're planning on using. I've gone for single stage 4.5:1 reduction with 75mm wheels

Re: Gears

8:1 would give you a nice mix of speed and power with 100mm wheels at 24v

Re: Gears

I've got 4 100mm wheels and I'm running at 12v.

[jonny]

Re: Gears

Ah I see, I'm planning to run on 13.2v Which is why I'm going for a lower ratio

[team_mayhem]

Re: Gears

12v id run 5:1 still fast and will have fair bit of push nice and controllable aswel as being single stage so easier and cheaper to make

Re: Gears

Little bit of advice, don't be a snippy little so and so if I ask a simple question to get some background on an exceptionally general question. If you want help then a little manners goes a long way

Re: Gears

Sorry I didn't mean to sound rude. But just to show you what my knowledge of gears is like. 8:1 may sound good to me but at the end it's just a number, I know what stage mean but that's it.
