• What are the effects of temperature change on the performance of JZQ500-23.34-1 soft tooth surface reducer

  Temperature changes have many effects on the performance of JZQ500-23.34-1 Soft tooth surface reducer, as follows: Influence on lubricating effect: Temperature changes will change the viscosity of the lubricating oil. At low temperatures, the lubricating oil will become too viscous and deteriorate in fluidity, making it difficult to form a good lubricating film on the surfaces of components such as gears and bearings, resulting in a decrease in lubricating effect and increasing friction and wear between components. At high temperatures, the viscosity of the lubricant oil will decrease, which will become too thin, and will also not be effectively lubricated, which will also aggravate wear. Influence on component size and gap: Metal components have the characteristics of thermal expansion and contraction. When the temperature rises, metal parts such as gears, shafts, and other metal parts inside the reducer will expand, which may cause the fitting gap between the components to become smaller, affecting the transmission accuracy, and in severe cases, it may even cause the components to be stuck. When the temperature drops, the components shrink and the gap may increase, which will cause shock and vibration to occur during operation, reduce the smoothness of the transmission, and accelerate the gears.

• What are the effects of temperature change on the lubrication effect of ZQ650-25-2S soft-tooth surface gear reducer

  Temperature changes mainly affect the lubrication effect of ZQ650-25-2S soft-tooth surface gear reducer: Influence in low-temperature environment: lubricating oil becomes thicker and fluidity weakened: At low temperature, ordinary lubricating oil will become thicker and fluidity will become worse. This may cause difficulty in starting the reducer. If it is started frequently, it will aggravate the wear of the gears and bearings, and even make the reducer unable to work properly. Lubrication delay: The increased viscosity of the lubricant oil will delay the time it reaches the lubricating part, making the gears and bearings not lubricated in time, thereby increasing friction and wear. This will seriously affect the transmission efficiency and life of the reducer in the long run. Increased operating resistance: Lubricating oil with poor low-temperature fluidity will increase the resistance during the reducer operation, resulting in an increase in energy loss, which will not only affect the efficiency of the reducer, but also increase energy consumption and operating costs. Influences of high temperature environment: oxidation and deterioration of lubricating oil: When the ambient temperature is higher than 40℃, lubricating oil is prone to deterioration due to high temperature oxidation and viscosity

• What aspects should be paid attention to when checking the operating status of the NGW122-40 planetary gear reducer

  In addition to conventional inspection items, the operation status inspection of NGW122-40 planetary gear reducer also needs to pay attention to the following aspects: Temperature condition: Oil temperature is an important indicator. If the oil temperature rises above 80℃ or the oil pool temperature exceeds 100℃ and is accompanied by abnormal noise, it may be caused by increased friction between internal parts, poor lubrication or clutch failure, and the machine needs to be shut down for inspection. Vibration and Noise: Use a noise detector and vibration detector to detect the noise and vibration levels of the reducer. Abnormal noise and vibration may be caused by wear of gears, damage to bearings or poor assembly. Lubrication system: Regularly analyze the oil in the reducer and detect the oil pollution degree, moisture content, viscosity and other indicators to judge the health status of the reducer. If the oil is obviously turbid or does not meet the indicator requirements, it should be replaced as soon as possible. Connecting parts: Check regularly whether the fastening parts such as connecting bolts, nuts, etc. are loose. If there is any looseness, tighten them in time to prevent them from being

• What are the dangers of problems with the installation foundation of NGW113-400 planetary reducer

  NGW113-400 If there is a problem with the installation foundation of the planetary reducer, it may cause the following hazards: the vibration and noise increase: the installation foundation is unstable or unstable, and the reducer will vibrate significantly during operation, accompanied by noise. This is because the instability of the foundation causes the reducer to generate additional shaking and impact during operation, causing vibration and noise. Accelerating wear of parts: Vibration and instability caused by basic problems will cause parts such as bearings and gears to bear additional load and impact forces, causing the wear of bearings and gears to accelerate, shorten their service life. Impact transmission accuracy: Inaccurate installation foundation may affect the meshing accuracy of the gears inside the reducer and poor gear meshing, which will cause errors during the transmission process, affecting the transmission accuracy and operating stability of the equipment. A possible shaft breakage accident: If the installation foundation problem causes the concentricity of the reducer output shaft and the driven part of the shaft

• List some heat treatment processes that can reduce the noise of the DFY630 gear reducer

  The following are some heat treatment processes that can reduce the noise of the DFY630 gear reducer: Normalization: The tooth blank is roughly processed into a fine forging and normalization. The purpose is to soften the steel parts for cutting, eliminate residual stress, refine grains, improve the tissue to improve the mechanical properties of the steel, and prepare tissue for the final heat treatment. During normalization treatment, the furnace temperature must be kept uniform, and station equipment should be used to heat and cool the workpieces evenly. It is strictly forbidden to stack them together. Tempering and tempering: This is also a commonly used preparatory heat treatment process, which can obtain good comprehensive mechanical properties, make the gear core part have sufficient toughness, and at the same time eliminate residual stress, reduce the deformation of the gear during subsequent processing and use, which helps reduce noise. High-frequency quenching of the tooth surface: The final heat treatment of the gear can be made using high-frequency quenching of the tooth surface. This process can make the tooth surface have high strength, hardness, wear resistance and fatigue limits, while the core remains sufficient.

• How to choose gear material suitable for hard toothed DFY710 gear reducer

  When choosing gear materials suitable for hard tooth surface DFY710 gear reducer, multiple factors need to be considered comprehensively. The following are the specific selection points: considering load conditions, light load, low speed or medium speed, low impact force, and low accuracy: medium carbon steel can be selected, such as Q235, Q275, 40, 45, 50, 50Mn, etc., and soft tooth surface gears are often made by heat treatment such as normalizing or tempering. Normalizing hardness HBS160-200, and general tempering hardness HBS200-280. In the case of medium load, medium speed, withstand certain impact loads and relatively stable movement: medium carbon steel or alloy tempered steel, such as 45, 50Mn, 40Cr, 42SiMn, etc., low-hardenable steel such as 55Tid and 60Tid can also be used. Hard toothed gears are made through high-frequency or medium-frequency quenching and low-temperature tempering, and the toothed surface hardness can reach HRC50-55. Heavy load, high speed or medium speed, and relatively

• How to avoid damage to parts when cleaning DCY250-31.5-4 gear reducer

  When cleaning the DCY250-31.5-4 gear reducer, damage to the parts can be avoided by: Selecting and using a cleaner correctly: Use cleaners compatible with gears and other components materials, such as gasoline, diesel or special gear cleaners, to avoid using abrasive cleaners or solvents that can corrode or wear the surface of the part. Reasonably disassemble parts: disassemble from the output end to the input end according to the transmission level to avoid damage to parts due to incorrect sequence. For parts that fit with the shaft interference, such as worm gear, it needs to be removed with a pulling horse or hydraulic tools. If the gear is stuck, inject penetration lubricant (such as WD-40) before soaking before operation. For corroded bolts, a combination of 'loosening agent + hot air gun' can be used to avoid forcibly breaking. Avoid knocking damage: It is prohibited to use an iron hammer to directly hit precision parts such as gears and shaft heads, and instead use a copper rod or nylon hammer. If you need to tap on the contact surface, you can use copper plate to buffer. Prevent parts

• How to determine whether the parts of DCY280-48.87-IIS hard-toothed gear reducer need to be replaced

  To determine whether the parts of the DCY280-48.87-IIS Hard-tooth surface gear reducer need to be replaced, you can use the following methods: Gear judgment method Appearance inspection: Disassemble the reducer housing and check whether there are scratches, pitting, peeling, broken teeth on the surface of the gear. The normal tooth surface should be smooth. If metallic luster wear marks or black sludge adheres, it may be abnormal wear. Dimension measurement: Use a tooth thickness caliper and a dial gauge to measure the wear amount of tooth thickness. The standard tooth thickness tolerance is usually ±0.05mm. It can also be judged by the engagement gap. The normal engagement gap is generally 0.1-0.3mm, depending on the model. If the tooth thickness wear exceeds 10% of the original thickness, or the meshing gap exceeds 50% of the standard value, replacement should be considered. Operating status monitoring: When starting the computer, monitor for abnormal noise, such as sharp friction sounds and periodic impact sounds. At the same time, the bearing temperature is detected. Under normal circumstances, the bearing temperature is ≤70℃, if it exceeds 8

• How to determine whether the dual-stage NGW121 planetary gear reducer needs repair or replacement

  To determine whether the double-stage NGW121 planetary gear reducer needs to be repaired or replaced, you can start from the following aspects: Appearance inspection: Check whether the reducer shell has cracks, deformation or damage. If these situations exist, it may affect the stability of its internal structure and needs to be repaired or replaced. Check whether the connection parts, such as bolts, nuts, etc. are loose. Loose connections may cause vibration and abnormal noise during operation. They need to be tightened in time. If the connecting parts are damaged, they need to be replaced. In addition, it is necessary to observe whether there is any oil leakage. If lubricating oil leaks in the oil seal, end cap, etc., it may be that the seal is aging or damaged, and the seal needs to be replaced. Sound judgment: The sound of the reducer in normal operation is stable. If there is a harsh, sharp, impactful or irregular sound during operation, it may be caused by gear wear, poor meshing, bearing damage, etc. It is necessary to further check the internal components and determine whether to repair or replace according to the degree of damage. Temperature inspection

• What are the common installation errors that affect the normal operation of the NGW42-35.5-7.5KW planetary reducer

  The following are some common installation errors that affect the normal operation of the NGW42-35.5-7.5KW planet reducer: Coaxiality difference: The centering deviation between the motor and reducer coupling is too large, and the radial deviation is > 0.1mm Or the angle deviation is >0.05mm When the input bearing is subjected to additional bending moment. In addition, if special tooling is not used during installation, knocking the bearing will cause loose fit between the inner ring and the shaft journal, and the interference amount is less than <0.003mm, which will cause minor wear. These situations may affect the normal operation of the reducer, resulting in the appearance of the outer ring raceway of the bearing 'False Brunch indentation', uneven wear of gears along the tooth width direction. Improper adjustment of meshing clearance: The gear meshing gap is too small, and the teeth surface will be adhered and worn due to compression under load; the side gap is too large, and impact load will be generated during startup or reversing, causing the teeth surface to peel off. Data show that for every 0.02mm reduction in side gap, the contact stress of the tooth surface increases.
