How to confirm whether the modified ZD50-3.55-III reducer can meet the performance requirementsTo 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.

What to do if the lubrication system of the ZD15-2.5-2 reducer failsZD15-2.5-2 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

How to reduce the load of WPS40-60-B reducer worm gear boxTo reduce the load on the worm gear box of the WPS40-60-B worm gear reducer, it is necessary to follow the idea of 'source load reduction → transmission optimization → operation control → protection pocket', combined with the characteristics of this type of reducer (small, large reduction ratio, low rated torque), priority is given to low-cost, easy-to-implement solutions. The specific measures are as follows: 1. Source load reduction: Reduce the actual resistance at the load end. This is the most direct method of load reduction. It starts with the load itself to reduce the output torque demand of the reducer. It is suitable for scenarios where there is additional resistance at the load end. 1. Clean load stagnation and frictional resistance. Check the moving parts of load equipment (such as conveyor belts, valves, small robotic arms), remove dust, debris, and rust on guide rails, gears, and bearings to reduce mechanical stagnation; add grease (such as lithium-based grease) to the sliding parts of the load end to reduce the sliding friction coefficient and reduce the static friction and dynamic friction that the reducer needs to overcome; if the load is fluid equipment (such as a small pump body)

How to prevent overload of WPS50-50-A worm gear reducerThe key to preventing overload of the WPS50-0-A reducer is to work together in four aspects: material optimization, lubrication upgrade, load control and regular maintenance. The specific measures are as follows: 1. Material and design optimization Worm Strengthening: Use 40Cr alloy steel and quench to HRC45-55 to improve the wear resistance of the tooth surface. Worm gear adaptation: Made of tin bronze (ZCuSn10Pb1), hardness HB80-120, forming a 'hard + soft' pairing with the worm to reduce adhesive wear. Parameter adjustment: Increase the worm gear displacement coefficient, increase tooth thickness and contact area, and reduce single tooth load. 2. Lubrication system upgrade Oil selection: Normal working conditions: ISO VG 320/460 mineral oil or worm gear special oil. Heavy-duty working conditions: synthetic lubricating oil (such as PAO), high temperature resistance (flash point ≥ 240°C). Forced lubrication: When the speed is >1500r/min, the oil pump is used to circulate oil, and the cooling

How to judge whether the FA107-YVPEJ11-4P-58.12-M1 reducer bearing seal is installed correctlyTo determine whether the FA107-YVPEJ11-4P-58.12-M1 reducer bearing seal is installed correctly, the core is to look at the sealing performance, operating status and installation accuracy. 1. Sealing inspection static inspection : After installation, first observe whether the contact surface between the seal and the shaft and bearing seat fits evenly without distortion or flanging. Gently pull the sealing lip with your hand, and it should rebound, indicating that the spring holding force is normal. Dynamic verification: Run the reducer without load and observe whether there is oil leakage at the shaft end. If the oil stain spreads along the shaft diameter, it may be that the sealing lip is worn or the spring has fallen off; if the oil leakage on the joint surface is linear, check whether the bolts are loose or the sealing gasket is aged. 2. Operating status monitoring Abnormal noise and vibration : If there is a hissing or periodic friction sound at the shaft end during operation, it may be that the seal is installed incorrectly, causing dry friction. Use a vibration meter to detect the vibration value. If it exceeds the equipment manual standard (such as ≤4.5mm/s), check whether the seal is wrong.

How to avoid damaging the seals when cleaning the F77-Y3KW-4P-NA80-M4 reducer bearing sealsWhen cleaning the F77-Y3KW-4P-NA80-M4 reducer bearing seal, the key to avoid damage is to select the right cleaning agent, control the cleaning intensity, and standardize the operating process. The specific operating points are as follows: 1. Selection and use of cleaning agents. Avoid strongly corrosive solvents: give priority to kerosene, gasoline or special metal cleaning agents. Grease containing solid additives is prohibited to prevent the seal material from being corroded or accelerated aging. Pay attention to compatibility: If you need to replace the cleaning agent, be sure to confirm its compatibility with the old lubricant first to avoid chemical residues that may cause seal deformation. 2. Cleaning operation specifications Gentle treatment : Use a soft brush or cotton gauze to remove surface oil stains to avoid scratching the sealing lip with the metal brush. Control the soaking time: Operate according to the instructions of the cleaning agent to avoid expansion or deformation of the seal caused by long-term soaking. Rinse thoroughly: After cleaning, rinse away the residue with clean water or compressed air to prevent chemicals from corroding the seals. three,

Does the WHS200-50-10 worm gear reducer need to be re-run-in after replacing the bearings?WHS200-50-10 worm gear reducer needs to be re-run-in after replacing the bearings, and must be carried out no-load+ in accordance with the specifications The core is to make the new bearing fit in a step-by-step manner under load. The core is to make the new bearing fit closely with the journal and seat hole, and at the same time adapt the meshing state of the worm gear to avoid early wear of the new bearing. The specific requirements are as follows: 1. Core conclusion: The bearing must be run-in after replacement. This model is a medium-to-large, low-speed and high-torque machine. There is a microscopic fit gap between the new bearing and the journal and seat hole. Running-in can eliminate the fit deviation and allow lubrication. Evenly adhering the film and checking for assembly hazards are key steps to ensure the life of the bearing and cannot be omitted. 2. General principles of running-in: first no-load and then load, first low speed and then rated speed, step-by-step loading, monitor temperature rise, abnormal noise, and vibration throughout the process. Stop the machine immediately for troubleshooting if abnormalities occur. Direct full-load operation is strictly prohibited. 3. Step 1: No-load running-in (essential foundation, cannot be skipped) 3.1 Prerequisite for running-in: after replacing the bearing, add sufficient worm gear
