Guys how do you make sure your gears do not fall off if they are not connected to the motor or the axel for a car robot

Help this project is due in a few days and I’m the only one in my class doing it this way

@Kritarsh Sorry for the late reply. Hope you were able to find a solution. If not, you’d need to provide a lot more detail. Normally the gear connected to the output shaft of a motor is either press fit, or screwed into place. The gears on the other axles are also either press fit / loose fit, or secured using set screws and/or shaft collars / lock rings.
