Roller is widely used in road construction railway construction etc. everywhere construction roller and other similar volume is relatively small but roller function is same road construction necessary machine if road construction if long time use will not vibrate this is what question?

I don't know if you don't understand how roller works? Vibration mode mainly adopts vibration mode including electromagnetic mechanical mode clutch and block vibration mainly caused by eccentricity caused by block on roller. Therefore once roller failure does not vibrate it is likely that supporting block shaft exists problems. Small roller models are mainly due to carelessness during welding, so simple repair. It's okay. In the second case, electromagnetic clutch may fail. The third case is that road roller fault occurs, roller causes roller fault.
