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

Clean up BW27-29 For impurities inside the cycloidal pinwheel reducer case, the standardized process of 'draining old oil → dismantling and cleaning → rinsing and drying → inspection and re-inspection' must be followed, focusing on removing impurities such as metal abrasives, seal debris, and lubricating oil oxidation deposits generated by gear meshing to avoid impurities from exacerbating tooth surface wear and If the bearing fails, the specific operating steps and precautions are as follows: 1. Preliminary preparation and oil discharge operation, shutdown and cooling: ensure that the reducer is completely shut down, and wait until the lubricating oil temperature drops below 40°C before operating to prevent burns from high-temperature oil, and to avoid incomplete discharge caused by suspended impurities when hot oil is discharged. Clean the outside: Wipe the dust and oil on the surface of the box, oil drain port, observation hole and other parts to prevent external impurities from entering the inside of the box during disassembly. Complete oil drain: Unscrew the oil drain plug to completely drain the old oil in the box; if the oil drain port is located high, you can unscrew the upper oil level screw plug or the observation hole cover to speed up the oil drain. For when using Read More

To confirm whether the modified ZD50-3.55-III reducer meets the performance requirements, four core links need to be passed: parameter verification, no-load test, load test, and durability verification. The details are as follows: 1. Check the modification parameter compliance and compare it with the original technical manual to review the key parameters after modification: ① Whether the transmission ratio is consistent with the design value of 3.55; ② Whether the rated torque and speed of the input/output shaft are within the allowable range; ③ Whether the installation dimensions (shaft diameter, center height, flange specifications) match the load equipment; ④ Whether the lubrication circuit and sealing structure are adapted to the new working conditions to prevent the risk of poor lubrication or oil leakage. 2. No-load trial run test (1) Add the designated brand of lubricating oil, control the oil level at the center line of the oil window, and manually turn the engine for 3 to 5 turns to confirm that there is no sticking or abnormal noise. (1) Start the reducer by jogging the motor and observe whether the running direction is correct; run continuously for 2~4 hours without load and record every 30 minutes. Read More

ZD15-2.5-2 reducer lubrication system faults need to first locate the fault type and then deal with it. The specific steps can be implemented directly: 1. Oil level abnormality troubleshooting The oil level is too low: stop the machine and cool it to room temperature, add the lubricating oil specified in the instruction manual to the center line of the oil window; check the oil seal and flange seal for oil leakage, replace damaged seals, and tighten loose bolts; if there is sandhole leakage in the shell, repair or replace the shell with oil-resistant sealant. The oil level is too high: drain excess lubricating oil to the standard oil level; check whether it is caused by water intrusion or excessive refueling. If water intrusion occurs, the lubricating oil must be completely replaced and the breather plug must be checked to see if it is blocked. 2. Oil quality deterioration troubleshooting If the oil turns black and contains impurities: drain the old oil immediately, flush the oil tank and oil circuit with kerosene or special cleaning agent; disassemble and inspect the filter, clean the impurities on the filter screen or replace the filter element; add new oil after reinstallation, and replace it again after the first 50 hours of operation to ensure that the oil circuit is clean. Oil emulsification: replace all oil Read More
