Are you building a new gearbox, upgrading old trusty to shoot a little faste/ hotter, or perhaps you just turned your gear set into a pile of metal shavings, it’s time to start thinking of new gears. There are so many options on the market claiming to be hi speed or super torque, but what does all that gibberish about ratios mean really. It’s time to tuck into the meat and potatoes of the Aeg the gear set.
What is a ratio?
Well a ratio is simply the relationship that a set of gears have to each other as well as the input and output of the system. For example a 16:1 ratio, commonly seen in gearboxes means that the input turns 16 times to the output’s 1 turn. But why? The electric motor that powers this system does not have enough power to both fit in the gun and move the piston back without some help. So the motor will turn 16 times for one turn of the sector gear (the gear that picks up the piston, amongst other things) . This will dictate ROF (rate of fire). Example your stock Aeg is shooting 10 Rps( rounds per second) and has a ratio of 16:1 essentially your motor is spinning at 9,600 rpm. How did I solve this
Simple formula:
Rof= (rpm of motor / gear ratio) /60
However this a very loose formula and does not take into account the spring fighting against the motor.
Example: a stock G&p shoots at about 20 rps with an m120 motor and 16:1 ratio. Which the motor is turning at 19,200 rpm, compared to is specs of 33000 rpm.
We will dig in deeper with this at later time.
So remember with the right motor you can increase Rof with lower ratio sets (13:1) and increase torque with higher ratio (18:1)
