Abnormal noise in the PU250-31.5 worm gear reducer is a direct signal of abnormality in the internal transmission system, lubrication system or assembly structure. If not handled in time, it will cause chain consequences such as increased component damage, transmission performance failure, and scrapping of the entire machine. The details are as follows: 1. Serious wear and failure of the worm gear pair. If the abnormal noise is continuous 'gnawing teeth' Sound is usually caused by excessive meshing clearance of the worm gear, uneven tooth surface wear, or poor tooth profile accuracy. Continuous operation will lead to gluing, pitting, and spalling on the tooth surface. In severe cases, the teeth will break, and the worm gear pair will completely lose its transmission capability. If the abnormal sound is accompanied by periodic metal impact sounds, it may be due to axial movement of the worm or loose positioning of the worm gear. Long-term impact will cause the fit between the worm gear hub and the shaft to loosen, the keyway to deform and shear, and eventually the transmission to become stuck. 2. When the bearing component is damaged or the shaft system fails and the abnormal sound is a sharp 'buzzing' sound or a 'rustling' sound, it is usually caused by insufficient bearing lubrication and raceway wear.

The abnormal sound 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 sound 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 operation of the bearing 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 Read More

JZQ750-40.17-I gear reducer is a medium and large transmission equipment. During the trial operation (no load/load), it is necessary to focus on preventing risks such as mechanical injury, electrical failure, oil leakage, etc. The safety precautions must cover the entire process before trial operation, during operation, and after shutdown. The details are as follows: 1. Safety preparation before trial operation 1. Regional safety isolation: Demarcate the exclusive safety area for the reducer trial operation, set warning signs (such as 'No entry during equipment trial operation'), and prohibit entry by unrelated personnel. Clean all debris, tools, and flammable objects in the area, and ensure that there is at least 1.5m of operating space around the reducer to facilitate observation and emergency treatment. 2. Personnel qualifications and protection Operators participating in the trial operation must receive professional training and be familiar with the reducer structure, operating procedures and emergency response procedures. Unlicensed personnel are strictly prohibited from operating. Operators must wear protective gloves, anti-impact goggles, non-slip safety shoes, and long hair must be Read More

The JZQ500-15.75-1F gear reducer no-load trial operation abnormality handling method is as follows: 1. General pre-processing process 1.1 Emergency stop: If any abnormality such as abnormal noise, excessive temperature rise, severe vibration, oil leakage, etc. occurs, immediately press the emergency stop button or cut off the power supply. Operation with faults is strictly prohibited. 1.2 Safety isolation: After shutdown, hang a 'No closing for equipment maintenance' warning sign on the electrical control box, wait until the reducer completely stops inertial rotation and naturally cools to room temperature (forced cooling is prohibited) before conducting inspections. 1.3 Record information: record abnormal phenomena (type of abnormal noise, temperature value, vibration position, oil leakage location), occurrence time, and trial operation stage in detail to provide basis for troubleshooting. 2. Common abnormal phenomena and targeted treatment plans 2.1 Abnormal noise treatment 2.1.1 Metal impact sound: Possible causes are excessive gear meshing clearance/tooth surface damage, broken bearing balls, Read More

The rated reduction ratio of WB120-LD-17-0.55KW micro cycloid reducer is 17. The core causes of abnormal output shaft speed (shown as low speed, speed fluctuation, and no output speed) are transmission connection failure, meshing component wear, poor lubrication status, and mismatch between load and working conditions. It needs to be checked and solved in the order of first external then internal, first easy and then difficult. The specific operation steps are as follows: 1. Prioritize troubleshooting of external transmission and connection faults (no need to disassemble, quick positioning) 1. Check the connection reliability of the motor and reducer Operation: shut down the power, remove the connecting flange of the motor and reducer, check whether the input shaft flat key/spline is loose, whether the keyway is deformed or worn; use a dial indicator to detect the coaxiality of the motor shaft and the reducer input shaft, the required deviation is ≤0.05mm. Solution: If the flat key is loose, replace the flat key with the same specification and apply thread locking agent; if the coaxiality exceeds the standard, adjust the positioning screw of the motor mounting base.

When encountering the problem of excessive temperature rise of the WB85-WD-11-180W reducer, we can quickly solve it in three steps: first stop the machine for troubleshooting, then deal with it in a targeted manner, and finally strengthen prevention. The specific plan is as follows: 1. Stop the machine immediately for inspection‌Safety first‌: Cut off the power supply to avoid burns on high-temperature parts. ‌Preliminary Observation‌: Check whether the lubricating oil is turbid, whether the oil level is normal, and listen for abnormal noises. 2. Core Problem Troubleshooting and Treatment 1. ‌Lubricating system problems‌‌Abnormal oil level‌: If the oil level is too high, it will increase the oil stirring resistance, and if it is too low, there will be insufficient lubrication. After stopping the machine to cool down, adjust the oil level to the middle position of the oil level gauge. ‌Oil product problem‌: If the oil is oxidized and deteriorated or mixed with impurities, the old oil needs to be completely drained, and the inside of the gear box should be flushed 2 to 3 times with new oil of the same type and then refilled. 2. ‌Load and installation issues‌‌Overload operation‌: Check the load conditions and reduce the operating load to within 80% of the rated load. ‌Installation deviation‌: Read More
