How to determine the fault of XWE63-1849-1.5KW horizontal cycloid pinwheel reducerThe method to judge the failure of XWE63-1849-1.5KW horizontal cycloid pin wheel reducer is as follows: Vibration abnormality: Phenomenon: The shell shakes significantly, and the associated equipment vibrates significantly. Cause: It may be that the installation foundation is unstable, such as the soft foundation or the installation surface is uneven; the eccentric sleeve bearing is worn, resulting in unstable operation; the cycloid wheel has broken teeth, affecting the transmission accuracy; the coupling centering error exceeds the limit, causing a deviation in power transmission. Inspection method: Use a level to check the installation base to see if its horizontal error is within the range of ≤0.02mm; for bearings and cycloid wheels, wear and breaking conditions can be checked through disassembly; use professional tools to detect the centering of the coupling. The temperature rise is too high: phenomenon: During the operation of the reducer, the oil temperature exceeds 85℃. Cause: Lubricating oil Selection is incorrect, not suitable for the current working environment and load; the equipment is overloaded and is in a high load state for a long time; the heat dissipation system is blocked, such as heat dissipation

Common XWE74-121-7.5KW cycloid reducer faults and treatment methodsThe common faults and treatment methods of XWE74-121-7.5KW cycloid reducer are as follows: Noise abnormality: Cause: Bearing wear, causing unstable operation to produce noise; poor lubrication, causing friction between parts to increase and noise; improper assembly, the gap between parts does not meet the standards, and collides with each other during operation. Treatment method: Check the bearing and its lubricating status, and replace the bearings with severe wear in a timely manner; adjust the assembly relationship to ensure that the gap between each component meets the standard requirements. The temperature is too high: Cause: insufficient cooling, the heat dissipation system fails, and the heat dissipation system cannot be effectively dissipated; the lubricating oil fails, and the lubricating performance decreases, resulting in increased frictional heat generation; the mechanical load is too large, exceeding the rated load of the reducer. Treatment method: Check whether the cooling system is working normally, add an appropriate amount of coolant if necessary; change the lubricant regularly to ensure its lubricating effect; for excessive load, appropriately reduce the load so that it is at the rated negative

Things to note when adjusting the gap between the hard tooth surface reducer in ZSC600-37.9-IWhen adjusting the clearance of the ZSC600 - 37.9 - I, the following precautions are given: Check the information in advance: Read the instruction manual or technical manual of the reducer in detail, and clarify the specific methods, parameter requirements and related precautions for adjusting the clearance of this model reducer. Different models of reducers may have differences in structure and adjustment methods, and following the instructions is the basis for ensuring correct adjustment. Ensure safe operation: Be sure to cut off the power supply of the reducer before adjustment and take reliable power-off measures, such as listing warnings, locking power switches, etc., to prevent accidental power-on-operated during the adjustment process and cause safety accidents. Do a good job of cleaning: Before disassembling the reducer shell or performing internal operations, clean the dirt and debris on the surface of the reducer to prevent these impurities from entering the interior during the adjustment process, affecting the gear meshing or aggravating component wear. Check the status of components: comprehensively check the gears, bearings, shafts and other related components.

Specific steps to adjust the gap between the hard tooth surface reducer in ZSC(A)500-33.1-4The following are the general specific steps for adjusting the clearance of ZSC (A) 500 - 33.1 - 4: Preparation: Check the instruction manual of the reducer to clarify the relevant requirements and precautions for adjusting the clearance of this model reducer. Cut off the power supply of the reducer and take safety measures, such as a warning for listing to prevent accidental power-on. Prepare the required tools such as a gauge, a dial, a vernier caliper, a wrench, a screwdriver, etc., as well as possible adjustment gaskets and other components. Clean the dirt and debris on the surface of the reducer and keep the working area clean. Measure the original clearance: You can use a feeler gauge to measure the gap between the two teeth, install the gear according to actual use, fix one of the gears so that it cannot rotate, use the feeler gauge to plug the tooth profile gap from the end face (the other gear can be rotated). The maximum reading of the feeler gauge that can be inserted is the tooth side clearance. You can also use a dial meter to measure the head in the middle section of the tooth profile of the movable gear.

What are the specific steps for replacing the lubricating oil of RF57-157-2.2KW reducerThe following are the specific steps for replacing the lubricant of RF57-157-2.2KW reducer: Preparation: Make sure the reducer has completely stopped running and the power is cut off, and prepare lubricant, oil connection container, wrench, funnel, filter, cleaning cloth and other tools suitable for the reducer. Oil drain: Place an oil-connecting container under the oil drain screw plug of the reducer, open the ventilator on the top of the reducer case, and then open the oil screw plug to allow lubricating oil to flow into the container. If the reducer has a magnetic plug on the oil drainage block, it needs to be removed and cleaned. Rinse (optional): After the old oil is basically discharged, a small amount of new lubricating oil can be used to rinse the inside of the reducer to remove sediment, metal particles and residual old lubricating oil in the box. The rinsed oil is also discharged through the oil drain port. Cleaning: Wipe the inside of the oil tank and oil pan with a cleaning cloth or filter to ensure that there are no impurities and dirt residues. If conditions permit, you can also use a special cleaning agent to clean it, but be careful to leave the cleaning agent residue after cleaning.

What range should the oil level of the BLD4-11-7.5KW cycloid reducer be maintained?The oil level of the BLD4-11-7.5KW cycloid pin wheel reducer should usually be kept in the centerline of the oil viewing window. A reducer with oil windows horizontally placed, when the machine is stationary, the oil level reaches 2/3 of the oil mirror can also be considered normal. This is because the cycloid reducer generally uses oil pool lubrication. The appropriate oil level can ensure that the transmission components such as gears are fully lubricated, and can also avoid excessive heat generated during operation due to excessive oil level, increased risk of oil leakage, or damage to components due to poor lubrication caused by too low oil level. If the reducer does not have an oil window, refuel when placed horizontally, remove the upper observation cover and insert it vertically into the bottom of the box with a dipstick. The oil level height is generally 55mm−65mm. However, reducers produced by different manufacturers may vary. It is recommended to refer to the equipment's instruction manual to determine the exact oil level range.

What are the manifestations of insufficient lubricating oil in BLD5-35-18.5KW cycloid reducerBLD5-35-18.5KW When the lubricant oil of the cycloid reducer is insufficient, the following may occur: abnormal temperature rise: During normal operation, the oil temperature of the reducer is generally maintained at 60℃-80℃. Insufficient lubricant will reduce the heat dissipation area and reduce the heat dissipation efficiency, and the oil temperature may rise to 90℃ or even higher. Long-term high temperature will accelerate the aging and deformation of the seal, resulting in oil leakage, which will make the lubricant oil even less and form a vicious cycle. Increased noise and vibration: lack of protection from lubricating oil, the friction between gears, bearings and other components increases, and the friction sound will be more obvious. At the same time, abnormal vibration may occur, affecting the smooth operation of the reducer. Intensified wear: insufficient lubricating oil cannot form a good oil film on the surface of the component. The contact surfaces of key components such as gears and bearings directly rub against each other, and the friction coefficient increases. For example, the friction coefficient between gears may increase from normal 0.05-0.1 to 0.2 or even higher.
