If I have a gear system that consist of 2 gears that are meshed together
the first has 16 teeth which is the driver and the 2nd has 36 teeths which is the follower,
power transmitted by the driver equal to 5 kw and the driver is rotating at 30 rps and has a known diameter, the usual way to find the tangential force that is acting on both gears is :
Ft=Power/Vdriver , Vdriver = 3.14xDiameter of the driver x 30 rps.
what confuse me is that the driver as well as the follower are rotating at cosntant velocity but at the same time they have a net torque on each one :
Net torque on the driver = FtxRadius of driver
Net torqe on the follower =FtxRadius of follower
Though we know that when a disk is rotating at constant speed the net torque exerted should be equal to 0 , but it is not the case in Gear systems , please explain .
p.s : is there any other forces that should be taken into consideration in the following gears that if multiplied by their radius will cancel the torque and the net torque of each one of the gears will become "0" ?
Thank you
