Here's the car at competition in Lincoln, Nebraska last year. This was the first year our university brought a car to competition. A very happy day for all of us.
We are upgrading our rear diff this year to a Drexlar unit, saving us a lot of weight and helping us put our power down a lot...
Cheers gearcutter, thank you on behalf of my FSAE team and myself!
Any chance you can generate DXFs of the internal spline, so I can get the sprocket wire EDM cut?
I'm reading the following:
38.47mm on the hub OD
28.20mm on from spline root to root (Sorry I forgot you asked for root to tip)
4.05mm tooth root to hub OD
6.16mm tooth tip to hub OD
I was able to take some measurements today as you described. I used pins that were 3.564mm, and measured 32.837mm across the two pins.
This came from imperial measurements at:
0.1404in Pin Dia
1.2928in Across Pins
gearcutter: I measured the BTL across the teeth as follows:
2 teeth: 10.20mm
3 teeth: 16.00mm
4 teeth: 21.38mm
I would say the error on these measurements is +/- 0.02mm. This was done with a digital vernier caliper, I can try to use a micrometer with the proper tips if necessary.
Thank you everyone for the feedback. Unfortunately the school is closed today and I can't access the pieces to check the measurements you provided. I have a photo that I took of the pieces mated together that shows a large clearance between the major diameters, which is what initially let me...
I'm trying to identify the spline that comes on a Honda CBR600RR transmission output shaft in order to produce a custom tooth sprocket for my school's FSAE team.
I have both the transmission output shaft and a new sprocket to measure, but I don't have access to measurement pins or any sort of...
