How to judge whether the cycloidal wheel of XWDY8095-29-0.37KW reducer needs straighteningTo determine whether the cycloidal wheel of the XWDY8095-29-0.37KW reducer needs to be straightened, it mainly depends on whether the deformation exceeds the allowable range, and is comprehensively evaluated based on the operating status and detection data. The following are the specific judgment methods and steps: 1. Deformation detection and standards 1. Straightness measurement Use a dial indicator or laser interferometer to measure the straightness of the cycloidal wheel tooth surface. The allowable deviation is usually ≤0.01mm/m. If the deformation is out of tolerance (such as >0.02mm/m), straightening is required. 2. Coaxiality measurement: Use a table method or a three-dimensional coordinate measuring machine to measure the coaxiality of the meshing surface between the cycloid wheel and the pin teeth. The allowable deviation is generally ≤0.01mm. If the coaxiality is out of tolerance (such as >0.015mm), straightening is required. 2. Observation of operating status 1. Vibration and noise If the equipment vibrates obviously or the noise increases during operation, it may be that the deformation of the cycloid wheel causes poor meshing. 2. Transmission efficiencyTransmission efficiency decreases (such as output speed fluctuation >5

Which one is more commonly used, hard tooth surface reducer or soft tooth surface reducer?In the overall market, hard-tooth surface reducers are more commonly used, and the segmented scenarios are different. Hard-tooth surface is the mainstream for heavy-duty/industrial core scenarios, while soft-tooth surface is still used in light-load/low-cost simple scenarios. It is divided into six points to clearly sort out: 1. Overall market usage: hard tooth surface rolling properties are more commonly used. In the current industrial reducer market, hard tooth surfaces account for about 55%-60%, soft tooth surfaces only 20%-25%, and the remainder are other types such as planetary and worm gears. The core reason is that under industrial upgrading, heavy load, continuous operation, and high stability requirements have become mainstream, and hard tooth surfaces have stronger adaptability and are gradually replacing soft tooth surfaces. 2. Industrial core scenes: Hardened tooth surfaces are absolutely commonly used as standard in heavy industrial scenarios such as metallurgy, mining, lifting, ports, cement, and chemicals. Hardened tooth surfaces are 100% common choice, almost no soft tooth surface applications. This type of scenario requires 24-hour continuous operation, heavy load impact resistance, and insufficient durability of the soft tooth surface. Use 1-3

What is the difference between the working principles of hard tooth surface reducer and soft tooth surface reducer?The core working principles of hard-tooth surface reducers and soft-tooth surface reducers are exactly the same. They both rely on gear meshing to reduce speed and increase torque. The only difference is only in the hardness of the gear tooth surface (different processing techniques), which does not change the nature of the transmission. Let’s explain the core logic and subtle connections in points: 1. Core working principle (the two are completely the same, no difference). Regardless of the hard tooth surface or the soft tooth surface, they are essentially gear transmission reducers and follow the same core principle: ① Deceleration logic: Using the meshing transmission of large and small gears, the small gear drives the large gear, and the output speed is reduced through the gear ratio. The larger the gear ratio, the higher the reduction ratio, and the lower the output speed; ② Torque increase logic: Under the premise of energy conservation, while the speed is reduced, the output torque is increased proportionally (deducting transmission losses) to meet the transmission needs of low-speed and heavy-load equipment; ③ Transmission form: The mainstream ones are helical gears, cylindrical gears, and bevel gears. The transmission paths and power transmission methods are exactly the same. For example, horizontal reducers are all

The specific measures are as follows: 1. Strictly control the intrusion of external moisture and eliminate water intrusion from the source (the primary cause of emulsification). Check the sealing system regularly. The bearing end cover skeleton oil seal of this model is every 6-month inspection 1 First, focus on checking that the lip is not damaged or aged, and that the outer ring is tightly fitted. If the lip is hard or cracked, replace it immediately. Reassembly must strictly follow the specifications to ensure the direction and coaxiality to prevent water seepage in the gap between the shaft and the oil seal. The seals on the upper and lower joint surfaces of the box and the end cover joint surface are inspected every year. If they are aged or degummed, replace them in a timely manner. The bolts are evenly tightened diagonally and there is no loose gap. Maintain the breathing valve. The breathing valve is the key to moisture prevention. Clean the filter element every 3 months to remove dust.

How to judge the emulsification degree of WPA200-40-A worm gear reducerTo judge the emulsification degree of the WPA200-40-A worm gear reducer, it mainly depends on the oil status, operating performance and testing data, as follows: 1. Oil status inspection, color and transparency: Normal oil is transparent or light amber, and after emulsification, it will become turbid, white or milky yellow, like batter. Impurities and precipitation: Take an oil sample and drop it on the filter paper. If there are metal debris or floc, it means serious emulsification. 2. Operating status monitoring Temperature: Use an infrared thermometer to measure the oil temperature. Normally it does not exceed 80℃. If it suddenly rises by more than 10℃, it may cause poor lubrication due to emulsification. Noise and Vibration: If there is a hissing or periodic friction sound during operation, it may be dry friction caused by emulsification; you also need to be vigilant if the vibration value exceeds the ISO 10816 standard (such as >8.5m/s²). 3. Oil performance testingviscosity: Use a viscometer to measure. If the viscosity drops by more than 15% or rises by more than 10%, you can

What are the causes of premature failure of the lubrication finger of the RX67-2.7-132B5 helical gear reducer?The core reasons for the premature failure of the grease of the RX67-2.7-132B5 helical gear reducer can be attributed to the following five categories: improper grease operation, excessive temperature, mechanical shear force, oxidative deterioration, and pollution intrusion. Let me help you break it down in detail: 1. Improper grease Selection and mismatched base oil type: For example, ordinary mineral oil is used in high-temperature environments, which oxidizes quickly and has a short life. It is recommended to choose synthetic oil (such as PAO or ester). Improper consistency: If the speed is high, but too thick fat is used, it is easy to be thrown out; if the speed is low, too thin is used, and it is easy to drain. The consistency grade must be selected according to the equipment operating conditions. Insufficient additives: Insufficient extreme pressure anti-wear agent, the tooth surface is easy to glue; insufficient antioxidants, the grease deteriorates quickly at high temperatures. 2. The temperature is too high and friction generates heat: gear meshing and bearing friction will increase the temperature. After the base oil evaporates, the grease becomes hard and the lubrication performance decreases. Environmental high temperature: For example, equipment near metallurgical furnaces with temperatures exceeding

How to deal with the emergency after the grease of RX97-2.64-22KW-M1 reducer failsRX97-2.64-22KW-M1 emergency treatment steps for reducer grease failure, core principles: first stop the machine to stop damage and prevent the fault from expanding, then perform emergency measures to ensure temporary operation, and finally make thorough rectifications to prevent recurrence, adapting to on-site sudden lubrication failure handling. 1. Immediately stop the machine and stop the loss (the first step is to prevent core components from being scrapped) 1. Emergency shutdown and power outage, hang 'No closing' Warning sign to prevent mis-starting; if accompanied by abnormal noise, high temperature, or stuck, forced start and stop is strictly prohibited to avoid broken gear teeth and bearing sintering. 2. Let it cool down until the temperature of the reducer shell drops below 40°C (to prevent hot oil burns and oil splashing) before carrying out subsequent operations. High temperature conditions Disassembly is strictly prohibited 3. Preliminary inspection of failure symptoms: observe whether there is oil or grease leakage, whether there are cracks in the casing, whether the feet are loose, listen to see if the cranking is stuck after stopping, record the fault phenomenon (abnormal noise, temperature, vibration) to provide a basis for subsequent processing 2.
