How much influence does magnetic anomaly have on the service life of H3SH14 industrial gearbox?

The impact of magnetic anomalies on the service life of the H3SH14 industrial gearbox is difficult to accurately quantify, but it may shorten its service life by 20%-50% or more, which mainly depends on the type and severity of the magnetic anomaly, the working environment of the gearbox and other factors. Magnetic anomalies usually affect the service life of gearboxes in the following ways:

• Leading to increased component wear : Magnetic components inside the gearbox (such as gears, bearings, etc.) may have residual magnetism during processing or testing. If magnetic abnormalities lead to residual magnetism on the gear surface, magnetic particles such as iron filings in the oil will be absorbed. These particles act like abrasives and will intensify the wear of the gear tooth surfaces and bearing raceways. For example, under normal circumstances, the gears of a gearbox can be used for 5 years. However, if magnetic abnormalities are not handled in time, serious tooth surface wear may occur in 2-3 years, leading to gear failure.

• Causing increased vibration and noise : Magnetic anomalies may cause uneven distribution of the magnetic field inside the gearbox, thereby generating additional electromagnetic force and causing increased vibration and noise of the gear. This vibration will not only affect the normal operation of the equipment, but also loosen the connecting parts of the gearbox, accelerate the damage of gears, bearings and other components, thereby shortening the service life. For example, a gearbox whose noise is originally within the normal range may experience significant increase in vibration noise due to magnetic anomalies, which may lead to bearing damage and reduced gear meshing accuracy within 1-2 years. Under normal circumstances, these components can be used for 3-4 years.

• Affecting the lubrication effect : Magnetic anomalies may cause the accumulation of magnetic particles in the lubricating oil, change the performance of the lubricating oil, and reduce the lubricating effect. When the lubrication performance of lubricating oil deteriorates, it cannot form a good lubricating film on the surfaces of components such as gears and bearings, which will cause the friction between components to increase, generate more heat, further accelerate the wear and aging of components, and thereby shorten the service life of the gearbox.

In order to reduce the impact of magnetic anomalies on the service life of the H3SH14 industrial gearbox, magnetic testing of the gearbox should be carried out regularly to detect and deal with magnetic anomalies in a timely manner. At the same time, the monitoring and maintenance of the oil should be strengthened to ensure that the gearbox is in good operating condition.
