I have a problem. Coming out....

[plovett]

I have a problem.  I have a "thing" for ring and pinions.

I have a 3.00, 3.07, 3.13, 3.15, 3.25, 3.33, 3.64, 3.75, 3.82, 3.89, 4.11, 4.22, and 4.33 gears.

I am fascinated by them in perhaps an unhealthy way?  I like having the perfect gear ratio for starters.  Second, I am fascinated by the differences in them.  The ones with more teeth have straighter gears which I think are more efficient.  And the pinion is especially affected by this.  The pinions with fewer teeth have a large "swirl" to them as the fewer teeth still have to encompass 360 degrees.  I think that makes them less efficient?  And the pinion itself is physically smaller which has to affect strength at some point.

My 3.13 gear has 47 teeth on the ring and 15 teeth on the pinion.  My best one in that respect.

My worst might be my 3.89 gear with 35 teeth on the ring and 9 on the pinion.   Numerically higher ratios get even worse.  Some only have 6 or 7 teeth on the pinion.

Can anybody help me?

Also, some of my ring and pinions are REM polished which is supposed to reduce friction and temperatures.  And some of them are lightened by removing "extra" material on the ring.  Who knew they could be so fascinating?

I don't see anything wrong with you.

Thanks, man!

You are sick. When you are put into an Old Farts Home (next couple months), you will be fondling gears in amazement, much like wide-eyed Hillary mesmerized by the overhead lights. And you worry about pinions that have 6 or 7 teeth? That's more teeth than I have in my whole mouth.

Things could be worse. You could be addicted to...uh...hmmm. OK, never mind, things can't be worse. You are screwed.

I named my 3.13 ring gear, "my precious".  Don't be jealous.  You can't have it!!!!

Ah. A Gear Gollum. It's worse than I thought.

Have never seen that ratio, but I know the roundy-rounders have every combo possible. There is a set of 2.47's in a parts car here, slated for my '72 N-code Gran Sport with 521 Blue Thunder 8V. I have NOS 160 MPH speedo in box. I'll race you to Hell.

I am imagining shifting into 2nd at 80 mph and into 3rd at 130 mph.  Yeah, you'll get there first.  Plus, cruising with "regular" traffic at 2000 rpm!  Overdrive?  HELL no!

Hold on a sec.....your 2.47 gear has 47 ring gear teeth and 19(!) pinion gear teeth?    I see what you're doing now. 

[FElony]

I have no idea about tooth count on the 2.47's. Still in car. '79 Ranchero GT with 351M. I got the car for 100 bucks with dead C6. Door tag says 2.47. If you saw what I "did" there, let me in on it.

The 2.47 gear has more ring teeth and more pinion teeth than any other Ford 9 inch gear, as far as I know.

Pinion envy, who knew?  I'm a 3:89 guy myself. Maybe because I have a soft spot for Ponchos. While I don't have a rear gear fetish, I do like the smell of well used gear oil & stale gasoline. Goes back to my childhood memory of exploring the neighborhood junk yard.

Hey, it's 2018 and if I like big pinions, no one can stop me!
