Is low gearing more torgue high gearing is more top speed

Question by chevy62    |  last reply


Hello! Convolution is almost done being taken apart, and I will be sorting it and counting it this weekend. Meanwhile, I've started on a new project. As of now, I only have a compact gearbox. I won't say what it does or how it works just yet, to make things interesting... :P For those of you who know, please do not spoil anything. Expect a full update around Christmas.

Gear design

Hello there, I was wondering if you could help me: I need a simple program to design a basic gear, a pair of twin wheels. I need to set the number of cogs and the diameter of the wheels; this mechanism has to be as tight as possible. The idea is to print the wheels on paper and then cut a metal sheet accordingly; can you tell me a way to transfer the image directly on the metal? That would be of great help... Thanks.

Gear Study

The last Friday of the month is a build day around Instructables HQ. I've been meaning to create some art involving gears of different pitches, so I took part of my build day to do a study in gears. These are two laser-cut acrylic gears I made on our Epilog 36EXT that are half 10 in pitch diameter and half 20 in pitch diameter. I advanced the 20 pitch side about one-half of a pitch. The gears were designed in OMAX Layout, which just happens to have a nice gear profile generator. I'm hopeful about putting together a set that gradually change pitch diameter.There's a bit of slop between the gears, and I'm taking advantage of it (at least in this set) to keep the teeth from colliding at the transition. They only rotate freely in one direction; in the other they bind.

Trademark Gear

Just think it's about time I make another forum topic. So yeah, do you guys have a trademark gear? Something that you wear all the time? Something that some friends even use to characterize or define you? (e.g. oh John? He's the guy with the headphones). My trademark gear are these MDISK MD-66 headphones. I wear them all the time and some of my newer friends doesn't even recognize me without these on because I wear them not only to hear music but so I can wear my hair differently. So, what's your trademark gear? Armbands, headphones, custom garskin-embed iPod, you name it!

Gear seeking?

 Hi all instructables dudes,  I have a scanner made by Pimax (model name Profi 9600) drived by a SCSI adapter. Is old model (1999) but is very good and reliable too. The problem now is i have a broken plastic gear that drives the belt for doing the passes during the scanning. Without this small gear the belt is dead and the scanner too. Has anyone this small gear from his old and non using scanner? If not please inform how can i reuse this scanner because everything else on it works fine. Can i modified it to a manual shifted scanner? This scanner is ONE pass so can I put any external case hand gear to move the lamp? Please give some ideas.....anyone is acceptable.... thank you all in advance! Agis

Question about gearing

Hi everyone. I've been a long time lurker, and I love the site. I've learned so much just by coming here. I've just registered to say you have inspired me to take on a project of my own. I've sort of hit a bump in the road, though. I have an idea for a clock. I want to do a steam-punk flavored wall or desktop clock with exposed brass gears and various and sundry bits I have laying around. I want to tack the numbers directly onto the gears and use them instead of hands. So one large gear on the left with the numbers 1-12 in place of an hour hand, one large gear on the right with 00-55 by fives for the minute hand and a gear under the two that counts off the seconds. So, if I can get a motor downgeared to 1 rpm to drive the "second gear" I'd need a 60:1 gear ratio to make the "minute gear" accurate, and then 12:1 off of that to do the "hour gear." I know I can't drive them all directly off each other, because that would make the "Second Gear" tiny and the "Hour Gear" huge. Where I'm stuck, aside from my poor math skills, is how to get the ratios right and size of each intermediate step and number of teeth, etc. I don't know enough to tell if I'm in over my head, but it seems "do-able" from my perspective. I'd appreciate any feedback you all could give, even if it's just a link to a tutorial that will get me started. I'm not on a deadline or anything, I just found the urge to make something cool. I have a bit of a budget if I need to have something custom fabricated, but I'd prefer to do as much of it as I can. I wouldn't mind using off the shelf stuff like bicycle gears or similar, because I could always have them engraved and plated and made to look cool. So, any help or nudges in the right direction would be appreciated. Thanks in advance, and thank you for such a wonderful site/community. Iggy **edited to add*** Of course I'd be delighted to write an instructable about it when It was done. It would only be polite. ;)

Ideal Gear ratio?

Hello i am competing in a design challenge at school. were were each given a 9v 12000 Rpm Motor, the object of the challenge is to build a land vehicle that can go 10m as fast as possible. we will be holding a race on november 3rd to see who has designed the fastest vehicle. anyway my question for the community is using a 12000 rpm electric motor what would be the best gear ratio to use between the motor and the axle to optomise take off speed as well as having a high top speed. (if the gear ratio is to high then the car wont accelerate fast enough to low then the car wont have a fast enough top end) so basicly im looking for that perfect med ground. if anyone here has had much experience with gears and help would be great thanks (PS the vehicle cant be any biger then a vhs case but can be as tall as i want it)

K'nex Gear Ratios

What Ratios Do the K'nex Gears Produce? I have noticed there have been a lot of questions about gears for k'nex models and in particular, engines but there have been no documents or information on what the different gear combinations actually convert the input speed to. On the document attached there are the worked out combinations and what the speed produced is, but you will notice that the combinations only go up to three gears; this is because if you have only three different gears, you will have to repeat atleast one gear therefore the ratio would be able to be created using less gears as intended.  The new file has now been uploaded. I hope this helps. MattJoeP

Gears for Servos and Steppers

Hey guys (and gals), I've been researching this a lot, but I still haven't the solution.  When you are working on a project and you need a gear for your stepper or servo, where do you acquire it?  For example I work a lot with TowerPro 996 servos, but I haven't found any third parties selling gears for them.   Same thing for motors.  If you are using a stepper motor, like a NEMA or something where do you find a gear that attaches to it?

Force an automatic transmission into a gear?

Is it possible in the technological day and age to force a computer controlled automatic transmission to start in a higher gear like second.  About 90% of people will never need this, however out on the farm in a big diesel truck with 800lbs of torque you need it.  By starting in a higher gear it allows us to get through snow much better and this becomes extremely difficult with an automatic transmission.  Sure we can set the highest gear it will go into, but we can't lug through the snow and mud like we would like to.  Do any of you know of a chip out there already, or one you can make that will let you pick and chose your lowest gear.

Attaching a Spur Gear onto a Motor

I want to attach a spur gear with a bore diameter of 6mm onto the shaft of this motor (6mm diameter shaft). How would I go about doing this? From what I see, the shaft is smooth so is my only option to find a gear with a set screw? Or is it sufficient to attach a gear with no set screw and simply rely on the friction of the bore? The torques will be low. Are there any websites that one would recommend for finding gears like this? I'm finding it impossible to find gears with a module of 1.0, bore diam. of 6mm, 12 teeth, and a thickness of less than 20mm to fit onto the shaft.Any help would be greatly appreciated.

Which Low RPM Gear Motor?

I am working on a robot that will have a grabbing claw, of sorts, and I'm not sure what gear motors to use to actuate the claw.  It needs to have significant gripping power, so the gear motor must be low-RPM and high torque.  The two best options I have found so far are these: 1. 12VDC Gear Motor, 7 Rpm 2-7/16" x 1-5/16" Dia. 2.  Tamiya 70110 4-Speed Crank-Axle Gearbox Kit   If I used the Tamiya gearbox, I would also have to buy higher voltage motors, so the cost of the two is approximately equal.  Because of its layout, I think the Tamiya would be easier to use, but I'm worried about stripping the plastic gears.  Also, I have a smaller Tamiya gearbox, and the axle has some play in it and is extremely noisy. The 12V gear motor, on the other hand, appears to be more robust and probably has metal internal gears, but it would make my robot a bit larger. Does anyone have experience with Tamiya gearboxes?  How do they handle high loads?  If anyone has any input on these two choices, or other motors you think would be even better, I'd really appreciate the help.  Thanks!

Looking for a Gear Set for 3D printing

A little over a decade ago I spent a large amount of time playing with lego technics. These mechanical legos had a set of gears with them that you could arrange in infinite variations and I loved them (still do.) What I would really like is file with a standard set of small gears that I could easily place into a 3D model and design around just like building something out of technics. The difference being that I get to design the parts connecting the gears instead of using lego bricks. These gears would ideally range in size from 5mm to 30mm diameter and would ultimately be used to make 8 inch or smaller robot things. Now, the obvious solution is to just make them, Inventor has a generator and they can be drawn in almost any program. The thing is that, well, it is over my head. I've used a lot of Sketchup, but am just getting into Inventor and 123D. Also, it turns out gears are incredibly complicated. I've looked at the diagrams and between the pitch diameters and diameter pitches and pressure angles I get lost, I'm not even sure where to start. On top of that, in my research I haven't found any kind of standard like there are with screws and electrical components; one can't just call the robot store and say "gimme some A5 gears good sir." So my questions are: 1. Is there a simple standard for gears? Specifically small plastic gears like those found in toys and clocks. 2. Do you have any advice on how I could go about creating my own "standard" set of small gears, like most important factors or common pitfalls, a magic button? 3. Am I going about this in a weird, round-about, wrong way? I'm learning as I go with 3D modeling/printing and I often fall down rabbit holes, this may be one. How would a professional engineer who is designing a toy go about choosing or creating his gears? Thanks in advance for any insight you can lend. These are the lego technic gears that are so dear to my heart
