Suppress the gear mate, rotate a gear to align it, suppress the gear mate.

If the gear teeth start off aligned and become misaligned as the gears are rotated, you may have a different sized teeth on each gear. Check the 'module' of the gear.

there will be lack of confinement of the gears, to prevent misalignment, after gear mates, sketch a circle on the hub of both gears and then mate these sketches with your gears as concentric. Maybe your problem get resolved.

Good luck!
