There are various reasons for the noise generated by electric winch reducers, including gears, bearings, lubrication, installation, loads, and foreign objects. The specific reasons are as follows:

Gear problem:

Poor gear meshing: Gear wear, tooth surface damage, excessive or insufficient tooth clearance, tooth profile errors, etc. can cause impact and vibration during the meshing process, resulting in noise.

Gear manufacturing accuracy: The bending strength, contact accuracy, motion accuracy, manufacturing accuracy, and working stability accuracy of gears all have an impact on the noise of reducers. Errors can cause intense pile foundation and vibration during the meshing process of gears, resulting in high-frequency impact sounds.

Bearing issues:

Bearing wear or damage: After long-term use, bearings may experience wear, fatigue, or damage, resulting in increased clearance between components and abnormal noise.

Inappropriate bearing clearance: Excessive or insufficient bearing clearance may cause abnormal rotation noise. For example, if there is a loud noise when lowering an empty load and a small noise when lifting a heavy load, it may be a sign of excessive bearing clearance.

Insufficient lubrication of bearings: Insufficient or inferior lubricating oil can cause increased friction in bearings, resulting in noise.

Lubrication issues:

Insufficient or deteriorated lubricating oil: Insufficient or deteriorated lubricating oil can cause direct friction between the metal surfaces of gears and bearings, producing a "rustling" or sharp "squeaking" sound similar to sandpaper friction.

Improper lubrication method: Unreasonable lubrication methods, such as insufficient or excessive injection of lubricating oil, may also lead to the generation of noise.

Installation issues:

Installation errors: Misalignment of input and output shafts, loosening of foundation bolts, unstable fixation of the box, and other installation errors can cause vibration and noise transmission during operation.

Loose components: Loose connections such as bolts, gears, bearing covers, etc. may also cause vibration and noise.

Load issue:

Excessive load: If the load borne by the gearbox exceeds the rated bearing capacity of the bearings, it may cause overload and overheating, resulting in noise.

Excessive load fluctuation: Excessive load fluctuation may also cause additional impact on gears and bearings, resulting in noise.

Foreign objects entering:

Metal debris, sand particles and other foreign objects: falling into the reducer can cause irregular "clicking" sounds and may exacerbate part wear.

Failure to clean iron filings during assembly may also cause gear jamming and noise.
