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

If the WBE1510-WD731-750 cycloidal reducer motor overcuts and trips, follow this process for quick troubleshooting: 1. Immediate power outage and preliminary judgment ‌Emergency treatment‌: Cut off the power immediately after tripping, touch the motor and reducer housing to determine whether the temperature is abnormal. ‌Manual turning‌: Check whether the transmission system is stuck. ‌Preliminary measurement‌: Use a multimeter to measure the three-phase current and voltage of the motor to initially distinguish whether it is an electrical fault or a mechanical fault. 2. Sub-module inspection‌ 1. Electrical system inspection‌: ‌Insulation detection‌: Use a 500V megger to measure the insulation resistance of the motor winding to ground. The normal value should be >0.5MΩ. ‌Three-phase balance test‌: Use a clamp ammeter to measure the operating current. The three-phase unbalance should be <10%. ‌Protective device inspection‌: Check whether the circuit breaker, fuse, and thermal relay are normal. ‌2. Mechanical system inspection‌: ‌Load end inspection‌: Remove the load and test run. If the no-load condition is normal, check the pump. Read More

WBE128-LD-187 micro cycloid reducer output shaft movement solution, details are as follows: 1. Shut down safety preparations, immediately cut off the power supply, wait until the reducer completely stops and the temperature drops to room temperature. Clean the surface and surrounding debris of the reducer, and mark the assembly of each component to prevent misalignment. Prepare tools: wrench, screwdriver, dial indicator, feeler gauge, new bearing/retaining ring/seal ring, thread glue, lithium-based grease. 2. Detect the amount of movement and locate the root cause of the fault 2.1 Use a dial indicator to attach to the reducer casing, place the probe at the center of the end face of the output shaft, manually push and pull the output shaft axially, and record the movement value; the normal axial movement of this type of reducer should be ≤0.15mm, if it exceeds it, it will be judged as a fault. 2.2 Locating the root cause of the fault: If the movement is accompanied by shaking of the shaft end, it is most likely that the output shaft bearing is damaged, the bearing clearance is too large, or the bearing seat is worn. If there is no shaking but the stroke is large, it is mostly the output shaft. Read More
