Torsional deflection in spur gear pinion?

Many years ago, the final drive for the M55, a 50 ton 500 horse power tracked vehicle, was redesigned and still failed. The cross drive transmission has splines that drive the pinions that drive bull gears that are on the same shaft as the sprockets that drive the tracks. An old man wants to know if there are now pre twisted spur gear pinions so, when highly loaded, a gear will be twisted straight. TIA

Chuckle!

You're kidding, right?

Once metal heat treated metal, as gears should be, has reached its yield point, it's not exactly reliable. I may be mistaken, but I think that's called broken teeth. Lets see what gear experts have to say.

OK- I think this time it may make more sense-----I should read what I post before doing so!

One problem with this type of system is what I believe is called recirculating horsepower. Although the engine might be able to provide

500hp to move the vehicle al> Many years ago, the final drive for the M55, a 50 ton 500 horse power

I think you are confusing horsepower with torque...
