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

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
