Drive line angles - Here's why they are critical

Recommended Posts

What wasn't shown was that at equal shaft angles and proper phasing, the driveshaft itself still oscillates dependent upon angle and as your suspension moves up and down, the driveshaft twists to accommodate the variation in angles and therefore speed at each end.

The point of the reference is that it is necessary to have the drive shafts in alignment when the axles are moved in singling so that the universals are only necessary for the variances in spring action and not constantly adjust for shaft misalignment.

 

That display was not necessary because that action of springs is understood.

It would be nice to find one like this for Constant Velocity joints to show why they are better (in some cases).

Just thought I'd stir the pot a bit for the more mechanically inclined or curious.

Stekay.....

 

Back in the stone-age I had a sharp kid ME only out of school a few years that had the bad luck of becoming involved in one of the "back-water-projects" I seemed to get wrapped around the axle with from time to time.........

 

The "kid-ME" loved complex linkages and grouser-wheel-wheerly-gig-thingy-ma-gigs.......so I had inherited the duty of loitering around the USSR prov at the Paris Airshow one year and was "befriended" by a Ruskee-engineer-geek" (ya right)......anyhow part of his "comrade-job" (cover) was to display the superior prowess of the high-level of mech-tech over the rest of the world.......so started my lowly life of........"trading-with-the-Ruskee".......the company I was hanging with at the Airshow had a booth in the U S prov and they were giving away penlights with the company on them........at that point in time the Ruskees were hell-bent on proving to the world that they had the biggest-of-whatever.....including flashlights.......but have you ever tried to work under the backside of a car dash with a flashlight the size of a basketball? So started my "life-of-Ruskee-tech-trading" this "Ruskee" offered to "trade" a complete 12 volume set of amazing mech-tech books for.........a couple cartons of penlights.......the books were never intended to be anything but bragging material to be waved in the face of us capitalists but this guy was so desperate to get rich in the black market back in the mother country he risk pretty bad juju for some give-away penlights.......pretty funny.....or sad when you ponder it.....

 

Anyhow as I recall few hundred pages of the Ruskee books involved complex drive lines and rotary joints as only a Ruskee-engineer could invent.......the funny thing is that as I recall some of these "concepts" found themselves into some "hardware" here in the free-zone.........who knows we just might have a few Ruskee-drive lines around us and not know it.....

 

The big-dogs got rich ( and life sentence) trading with the Ruskees........I got a hundred pounds of books that many engineers would need a lot of booze to decipher.......

 

Drive on.......(Keep those drive lines ........smooth)

Okay, I've resisted long enough. Has no one else noticed that the drive shaft in the video was improperly assembled. Duh. Any 12 year old farm kid knows better than that.

 

So, who can point out the error?

yokes are not clocked right

what do i win ??? :)

Good theoretical information!

 

Now for the practical information. Does anyone have a "link" that they can post to show how to verify drive line angles are correct, after singling (or during the singling process)?

 

I am in the process of stuffing a 1998 Yamaha V4 1200 cc VMAX motorcycle engine into my Yamaha Rhino. This is a new build. I have to align engine to divorced transfer case and then divorced transfer case to the front and rear differentials.

 

I will have to align the shafts in both the vertical and the horizontal axis. I have a precision machinist level for the vertical. I am stuck on the horizontal axis. I am thinking about using lasers (firearm laser sights) for horizontal axis alignment.

 

And, I am stuck

 

Although my project is for a Rhino, the process will be valuable to all HDT'ers who want to single their truck.

Turn the rhino on it side? Or how about a compass?

Jim,

 

Using TWO dial indicators common methods of shaft alignment are:

 

1. Reverse Dial method

2. Face rim method

3. Double radial method

 

Many industrial general machine installation refs will describe the above methods in detail.

 

If you have access to a Ipad you might want to use a Ap called iAlignCalc by Motonics LLC ( At theApple Aps store) I have the Motionics Vibration equipment and bearing and gear and single & two plane balance software that has worked well for me for the last few years.

 

If you have a industrial electrical motor repair shop nearby they likely have a computer laser alignment unit that will make short work of the alignment task that you need.

 

Take a peek at: https://www.myodesie.com/wiki/index/returnEntry/id/2955

 

Drive on.....(Align with care.....)

Only 35 minutes from the time I post the question and RB nails it. One ATTA-BOY for RB!

 

Hooking up various pto driven equipment over the past 50 years make me wanna scream when I see silly misteaks like that. And that video was supposedly done by enjinears?
