Adriaan, This is a "Helicon": Cheers,

Adriaan,(bithkits), That is a "HELICON"; the tapered worm was the "SPIROID"; Was itw division.Gear resembled a spiral bevel gear. HELICON series ranged from 1.500" OD Gear to 24.000" OD, the book listed 31:1/38:1/47:1 ratio's. One problem as I recall is none symmetrical pressure angle...

Matt, SAE J498 did not have the total range of spline pitches that ANSI B92.1 did. Also the internal only had one size the external was class1 & class2, B92.1-19xx had class 4,5,6 & 7 for both internal & external. SAE was only 30°PA, B92.1-19xx also covered 37½° & 45° splines, formerly 45°...

Jimmy, Here you go, the spiral data is included, as it's referenced by the hypoid equations. Cheers, Winston.http://files.engineering.com/getfile.aspx?folder=4dbccf8a-4b62-41a7-8caa-6e4876b96b80&file=NDHVOLII.pdf

Hi, The Timken equations differ significantly from my ancient "New Departure Handbook", that I used for many years. The NDH equations take Pinion Pressure Angle & spiral angle into account as well as pinion drop. These equations were for ball & double angular contact, but the forces from the...

Here you go, and, Lists full data wire size etc. Cheers,

galeblank, When the external is hobbed, it is involute form & accepted as it is so slight a deviation from straight. Dimensions listed are for the old SAE J500 straight serrations, 1/2-36.[About 1962]. I may have posted long ago on my Photo-bucket account I'll check & get back. Cheers,

Start making a note library, for different materials, Nitraloy, chrome-moly, and the different stainless groups, 17-4, 15-5 etc they do move differently, record before & after dim's, to obtain you own experience of fudge's of so much per in/in or mm/mm. AFM. Abrasive flow Machining was the way...

Hi friends, Can anyone tell me how do I draw spline tooth profile having modified tooth thickness (maximum actual). I have a LSP program but it draws the teeth with basic space width. I need to use this profile for checking broached components on a profile projector. But my problem with the...

Table 3, foot note (a) clearly states, class 5 tabulated value, other classes tabulated value times the various class multiplier. The profile & lead errors contribute to the effective fit of a spline set, when comparing actual and effective tooth/space sizes.

O, Fellows Shank cutter tapers: #1 morse, with 0.4750" Gage dia, by 1.000" long. #2 morse, with 0.7000" Gage dia, by 1.500" long. Fellows Short Taper, 1.0625" Gage dia, by 1.500" long. Fellows Long Taper, 1.0625" Gage dia, by 2.250" long. All with appopriate drawbar thread in the ends...

U, 1970 nfag data. Don't see your precise suffix, (old data), Possibly regreaseable & Phenolic cage? Cheers, Winston H.

M, you never did share your tooth data. Anyway, here is a 23 tooth, 32/64 DP 30deg PA, Fillet Root Side Fit Class 5, with one tooth cut away.

M, 19T,32-64 DP, 30 deg PA, Class 5: Flat Root Side Fit, (Min Minor 0.539"?) Fillet Root Side Fit? (Min Minor 0.519"? Min Fillet, 0.009"?)

Only 0.003" rad possible beyond given form dia, drawn with 0.19935"CSW. With mate equall to .006" B/Lash.?? Any additional data? How do I post a File? eg, a (.dxf)? Cheers WH.
