wheel balancing ?

[davecrowley]

I have found a static balance is as good as dynamic if done spot on.

You tell that to the young bloke's of Today, motorbikes were doing well over 100 mph before someone thought of dynamic balancing .

My BST's weren't balanced when I had new tires fitted. Didnt notice till after Phillip island doin 285+ but they were fine.

It's a bitch that the wheel rotates while you are riding. That is only the static balance good enough to get you to the shop and have it balanced dynamically. I would strongly recomend against riding even on the street without having wheels properly balanced, both of them. Otherwise it will affect your steering and cornering. You might not feel any shaking at all and there will be no warning. It will be just a classic case of "bike doing something unexpected", and after you dust yourself off (if you're lucky) you will be wondering what the hell just happened. Do not forget that even at 110km/h that wheel spins at 1000 rpm.And centripetal force is a square funcion of the velocity.

What a load of bunkum.

try more like 3000 rpm.
"static balance" is done with a wheel in the horizontal plane only and not able to spin.

rotating the wheel is the same wether done slowly or quick on a machine. a wheel properly done on a balance jig like this will seldom need further adjustment if checked on a machine. as others have said motorcycle wheels are not wide enough to be seriously effected by weight across the rim.

Your wheel spins at 3000 RPM at 110km/h? You are running a pram wheels on your bike? Suggest doing some simple maths.
I mentioned the rpm of the wheel so you could undertand the effect of little weight at high radial velocity. Your statement that the "static balance" is done with a wheel in the horizontal plane only and not able to spin." only indicates to me that you have no clue about the difference between the two. Yes, the motorbike wheels are narrower than cars and the effect is therefore lesser but the laws of physics are the same.

look up a dictionary "static" basicaly means still.!!!!(pertaining to or characterized by a fixed or stationary condition. )


a static balancer is used by picking the wheel up and placing it on an inverted cone on a needle point. in the horizontal plane. weights are then placed to make the wheel balance level. it dont turn. ie: it is static.
I have used more than a few of them.
Google it. plenty of pics around of the way it used to be done. for that matter it is only in the last 15-20 years that anybody even bothered doing bike wheels. got along just fine before that , if you were fussy you wrapped solder around the spokes. been riding bikes for better than 40 years now, picked up a thing or 2 along the way.

a dynamic balancer spins the wheel and indicates wether weights should be placed on the inside or outside edge of the rim. When was the last time you saw weights put anywhere but the centre of a bike rim?????? given that, even done by machine bike wheels are only simply balanced. it just aint wide enough to require dynamic balance.

I'l give you the rpm but it is still more than 1000 rpm.

110 kilometers per hour is better than 1800 meters a minute. wheel aint a whole lot more than a meter around. gotta mean more than 1000rpm.

1m would mean a circumference of around 320mm...... i would say most bike wheels (including tyres) would be around double that and have a circumference of around 1.8 to 1.9m.

RPM would be under 900rpm.

Absolutely nothing wrong with static balancing. I know for a fact that my home made balancer is accurate to within about 4 grams. I use clamp on weights in the centre of the bare rims to balance the bare rims. Then stick on weights to balance the difference with a new tyre. At 200 kph a front tyre that is out by 10-15 grams is quite noticable. If you are rarely running big speeds even 40 out on the rear is hard to pick. I aim for less than 5 out front and rear. Takes about 20 minutes per rim. Simple fact is you can run new tyres static balanced to within 5 grams as fast as your bus will run and it wont shake. Paul.

for fck sake this is a STATIC balancer



Anything else aint.


Static = dont bloody move

[Skidmarx]

Nothing like the static balancer i currently use for drag tyres :P

Not doubting its ability though

Keep ya shirt on. In recent times many people refer to the manual method of balancing a wheel on a centered spindle as static balancing.Lets call it manual balancing as opposed to powered balancing. Whatever you choose to call it, when done correctly it is a completely acceptable and accurate method especially on the most important end of the bike.

My point exactly. You are bloody well right, Manual and automatic. same result.

Tom.


some want it put on a machine and anything else is just not acceptable. many ways to skin the proverbial.

Mate, everything else aside, I am very curious how do you use that gizmo on your photo to balance the wheel?

There like a spirit level, gotta get the bubble in the middle

[tomrux]

post 21 mate. but yeah get the bubble in the middle. weight is only put on the outside rim. hence the leap forward when machines came in and indicated where, on the comparativley wide car wheel, the weight would be best put.
