The abnormal noise of the TPS200-63-4F worm gear reducer will directly accelerate the wear of internal components, destroy the normal transmission state, and significantly shorten the service life of the equipment. The specific impact mechanism and degree are as follows:
1. The relationship between the source of abnormal noise and life loss
If the abnormal sound is the worm gear meshing impact sound (clicking sound): it is mostly caused by excessive meshing clearance, uneven tooth surface wear, or excessive assembly coaxiality. Continuous impact will cause pitting corrosion on the tooth surface and accelerate the gluing speed. The worm gear pair originally designed to have a life of ≥10,000 hours may have teeth cracked within a few months, shortening its life by more than 60%.
If the abnormal sound is a sharp whistling or rustling sound from the bearing: it is caused by insufficient bearing lubrication, raceway wear or cage deformation. Abnormal bearing operation will generate high temperatures, leading to fatigue spalling of the raceways, and the bearing life will plummet from the designed 20,000 hours to 3,000-5,000 hours. At the same time, bearing damage will cause the worm shaft to move, further aggravating the worm gear meshing unbalanced load.
If the abnormal sound is box resonance: it is usually due to loose anchor bolts or non-concentric couplings. The vibration will be transmitted to worm gears, bearings and other components, causing loosening of the connecting parts, wear of the mating surfaces, and a decrease in the stability of the whole machine. Long-term resonance will cause cracks in the box, directly leading to the scrapping of the reducer.
If the abnormal sound is a dry friction sound caused by insufficient lubricating oil: there is no oil film protection on the metal contact surface, and the wear rate increases by more than 10 times, which will cause serious scratches on the worm gear tooth surface in a short period of time. At the same time, the bearing raceway will be sintered, and the equipment will completely lose its transmission function.
2. Life decay process of abnormal noise development
Initial abnormal noise (slight wear): only some parts have abnormal fit, and life loss is relatively controllable. After timely inspection and repair, it can be restored to 80%-90% of the original design life.
Mid-term abnormal noise (component damage): There is obvious wear on the tooth surface and bearings, and the transmission efficiency decreases. If not treated, the service life will be shortened to 40%-50% of the original design.
Later abnormal noise (fault worsening): cracks, deformation, and fractures occur in components, causing chain damage. The equipment life is only 10%-20% of the original design, or even directly scrapped.
3. Core conclusion
Abnormal noise is a 'fault warning signal' of the reducer and is not a normal operating phenomenon. Any continuous abnormal noise will directly reduce the service life. Locating and repairing the source of abnormal noise in time is the key to avoiding a sharp decline in service life.
