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

The key to preventing motor damage of the BW18-43 cycloidal pinwheel reducer lies in the synergy of matching, load optimization, regular maintenance and protection devices. The following are specific measures: 1. Selection and matching ‌power and torque‌: Select a motor with sufficient rated power and rated torque according to the actual load demand to ensure that the motor can easily drive the load. For example, for shock loads, a motor with a higher overload capacity should be selected. ‌Voltage matching‌: Ensure that the rated voltage of the motor matches the actual power supply voltage, and the deviation should be within the allowable range (generally ±5%). If the voltage deviation is too large, it will affect the performance of the motor and increase the risk of overload. 2. Optimize load operation and avoid full-load operation: the actual operating load of the motor should not exceed 80%-90% of the rated load, and a certain power margin should be reserved. ‌Load Scheduling‌: Reasonably schedule and manage the load to avoid a sudden increase in load. For example, in production Read More

Install BW13-87 correctly The core of the motor supporting the cycloidal pinwheel reducer is to ensure the coaxiality accuracy of the motor and the reducer, the connection parts are fastened reliably, and the stress is uniform, so as to avoid vibration, bearing damage or motor burnout during operation. The specific installation steps and operating points are as follows: 1. Preparation before installation Prepare tools for inspection: Prepare torque wrench (20~100N·m), Allen wrench (4~8mm), dial indicator and gauge base, rubber hammer, level, feeler gauge and other tools; prepare elastic couplings (such as plum blossom couplings), lock washers, positioning pins and other accessories. Component inspection: Clean the surface oil stains and burrs on the motor shaft extension end and reducer input end flange, check whether the motor shaft keyway matches the reducer input shaft keyway, and whether the key block is intact and without deformation; check whether the motor anchor bolt hole corresponds to the bolt hole position of the installation foundation, and whether the reducer output end is firmly fixed. Foundation leveling: Make sure to install the foundation (bottom Read More

To determine whether the YTC902-220-11KW shaft-mounted gear reducer needs maintenance, it is necessary to combine appearance inspection, dimensional measurement, operating status observation and safety and economic evaluation. The following are the specific methods: 1. Appearance inspection (off state) ‌Tooth surface wear‌: ‌Uniform wear‌: The tooth surface loses its luster, presents a uniform 'frosted feel', and the edges of the tooth top and tooth root appear rounded. The tooth thickness wear of hard tooth surface gears exceeds 15% of the original tooth thickness, and the tooth thickness wear of soft tooth surface gears exceeds 20%. ‌Local wear‌: 'step-like' wear occurs locally on the tooth top, tooth root or tooth surface, resulting in a reduction of more than 50% in the meshing contact area. ‌Pitting corrosion‌: Dense pits (diameter >0.5mm) appear on the tooth surface, and the pitting area exceeds 30% of the total tooth surface area. ‌Gluing/scratching‌: Strip or block-shaped damage appears on the tooth surface along the sliding direction, and in severe cases, the metal falls off. ‌Tooth root wear‌: Local wear occurs at the transition fillet of the tooth root, which may be accompanied by micro cracks Read More
