Will the inclination angle of the oil tank affect the noise level of the gear reducer

Yes, the inclination angle of the oil tank will significantly affect the noise level of the gear reducer.

This impact is not direct, but rather triggers a series of chain reactions by damaging the lubrication and mechanical structure inside the gearbox, ultimately leading to increased noise and vibration.

How tilting can cause an increase in noise, as follows:

1. Uneven lubrication and failure

Oil level imbalance: Gearboxes usually use oil pool lubrication, and are designed assuming they are in a horizontal state. Once tilted, lubricating oil will accumulate on one side of the oil pool due to gravity.

Partial oil shortage: Gears and bearings located at high positions may not be fully immersed in lubricating oil, resulting in insufficient lubrication or even dry wear. The direct contact between these metals can cause severe friction, wear, and abnormal noise.

Increased oil stirring resistance: Gears located at low positions may be immersed too deeply in the oil, resulting in a sharp increase in the resistance to stirring the lubricating oil during rotation. This not only causes energy loss and oil temperature rise, but also generates additional vibration and noise.

2. Abnormal force on mechanical components

Deterioration of gear meshing: Tilted installation may cause slight force deformation of the gearbox housing, resulting in deviation of the center distance of the gears. This will disrupt the ideal meshing clearance between gears, leading to increased meshing impact and resulting in greater vibration and noise.

Shortened bearing life: Tilting can cause the shaft system to bear additional loads beyond the design range. For example, data shows that for every 1 degree tilt of the axis of a planetary gearbox, the bearing life may plummet from the designed 30000 hours to less than 8000 hours, and bearing damage is one of the main sources of vibration and noise.
