Additive frequencies
Additive frequencies
(OP)
Is it possible to have a gearbox with a 30Hz input and 35Hz output shaft speed cause a 65Hz vibration frequency response? We have a machine with repeat bearing failures which has a dominant frequency of vibration at 65Hz which lines up to nothing else except the addition of the input and output shaft speeds??

Just a thought. One of many ways for modulation to occur.
