I use 2010 so not exactly sure if it is the same in 2013.

Terry,
A good reference for lead modifications can be found in AGMA 927:A01. It has some good examples and demonstration spreadsheets and computer flow diagram.

It would appear that you need to "normalize" the following
dimensions: (Cr, Ro1, Ro2) per the second paragraph of section 3. BASIC GEAR GEOMETRY
This would then give these as:
Cr = 78
Ro1 = 11.5
Ro2 = 68.5
Rb1 = 9.866
Rb2 = 63.429
using these would calculate
Rm1 = 10.5
p1 = 2.955
p2 = 23.722...
RPM from 460 to 1600 on input at 6,000 kW, helical gear design with Spherical roller bearings. Oil Spray not Splash lube, will probably be using 460 grade oil. Application is heavy industrial.
I have an engineer designing a new gearbox. Typically when we design a gearbox we are fitting into an existing system. this time we are designing a new gearbox for a new system. How do we specify the correct oil pressure for the central lube system?
The standard normal tooth thickness (without backlash) for these gears would be 1.57mm (0.062"). Backlash is typically chosen by application, I typically use a backlash of approx 1% of the normal thickness for a new design so 0.016mm (0.0006") per gear which equals 0.032mm (0.0013") backlash in...
This sounds like it is really a coupling design more than a simple spline design, is there a requirement for this coupling to accept any angularity. I would suggest using some standard geared couplings (flex/rigid combination).
Regards Chris.
I would suggest trying to reduce the Specific sliding (Slip) ratio of the gearset. I am assuming since you do not state the center distance that the gear and pinion operate at 4.833" centers (Standard Centers) this would gives slip ratio on the pinion of 3.184 and 1.609 on the gear.
