Incorrect velocity of gears in Gearbox

Hi everyone,
So I'm a building a single stage gearbox as depicted in the figure below in Simulink.
Gear 1 (N = 17 teeth) is given a constant torque of 1000 Nm and meshed with gear 2 (53 teeth).
When I run the simulation I get a ridiculously high velocity profile for either gear that keeps increasing as time passes. Should this value not remain constant? What am I missing that could possibly cause this?
Any help is appreciated!

The simulation results you have plotted are correct. You are applying a constant torque to both gears. Applying a constant torque to a rotational system with no damping will result in a system that just keeps accelerating (Torque = Inertia* Acceleration). If you want it to settle at a constant speed, you need to do one of the following:
