If you want CMM measurements contact Horsburgh & Scott in Cleveland. They are a gear company with a CMM machine with a 4 x 4 x 2 meter measurement envelope. Your 12 foot diameter gear would just fit. You can find pictures of it on their website. I don't know how close you are or how much it...
Create split lines on your surface that intersect where you want to apply your concentrated load. I don't know what program creates .cae files so I can't tell you how to create the split lines. If you create split lines on your surface most meshers will use them as boudaries and put a node at...
The link below is for an article which explains how to size welds using data derived from FEA.
See if it helps you.

Occupant: The involute profile is defined in the transverse plane. (The plane perpendicular to the axis of rotation). It is the path a point on a string takes as it is unwrapped from the base circle.
The involute profile in the transverse plane is swept in a spiral path to create a helical...
The surface of a helical tooth follows a spiral path around the axis of rotation. The pitch of this helical spiral is constant. It is called the lead. It is the distance a point on the profile travels in the axial direction if it were to extend 360°. This is why the helix angle is different at...
Your middle mouse button (MMB) may be bouncing or you mapped a single click to return a double click. You double click the MMB to put it in rotate about an entity mode. A single click would let you free rotate. Check how your buttons are mapped with your mouse driver or try another mouse.
If you want to save a drawing template you need to save as a .slddot format. What you did was save the sheet format which is the .slddrt file. The .slddrw format is the actual drawing.
The pinion and gear can be the same hardness but often the pinion is made harder than the gear because it is usually smaller and sees more cycles than the gear and making it harder help to balance rating between the pinion and gear.
You did not describe what mining application you are getting...
You have to talk to someone familiar with the torque-speed capabilities of the motor. Knowing this would help you determine if you need a gearbox in front of the motor and what ratio is required for the gearbox.
The power need to turn a shaft 80 rpm with 9000 in-lbs of torque is 11.42 HP. Some motors can take momentary overloads but usually not 6 times overload. So it is not possible to do this with a 2 HP motor.
Do the chatter marks coincide with tooth mesh frequency of any of the gears in the gearbox? It may be you have a dynamics problem which the tooth mesh frequency is exciting.
