Question

In a gearbox, there was a growling noise indicating a broken or dented tooth. The gearbox has a reduction ratio of 1.3 with a 72 teeth driver rotating at 4000 rpm. Calculate the frequency of this hunting tooth.

00:02 Hello guys in this problem we have the angular speed or the speed of the motor gear omega a is 1500 revolutions per minute the number of teeth in the gear motor gear that is t a equals 60 now we have the number of teeth in the driven gear t b equals 40 we need to find out the speed of driven gear omega b for a gear system we defined omega a times t a equals omega b or from this we get the speed of the driven gear equals the speed of the driver into the number of teeth in driver over the number of teeth in the driven gear...
