I am referred to a gear (helical) rattle under both unloaded and loaded (?) condition. The gear box is that of a screw compressor (positive displacement). I can understand rattle under unloaded condition, due to a probable higher dynamic torque, which would aid in the separation of the gear contact. But rattling with full load is a bit misleading. The vibration levels measured in the gear housing shows higher amplitudes at gear meshing frequency. Is there any other possibilites for gears to rattle under load?
