The main factors affecting the heat treatment hardness of the gear reducer are as follows: Material factors Carbon content: Carbon content is the main factor determining the hardness of steel. The higher the carbon content, the higher the hardness of the steel, and the higher the hardness after quenching. The carbon content of steel from different manufacturers and batches may vary, which will affect the hardness after heat treatment. Alloy elements: Almost all alloy elements can improve the strength and hardness of steel to varying degrees, such as Si, Mn, Ni and other elements have significant strengthening effects; Ti, Mo, Cr, Mn, W, V and other elements can combine with carbon to form carbides. When distributed uniformly, the hardness and wear resistance of steel can be significantly improved. Tissue grains: The raw material structure is severely uneven and some grains are too coarse, which will directly affect the uniformity of hardness after quenching or the hardenability of the material, resulting in uneven hardness. Decarbonization layer: If there is a decarbonization layer, oxide scale on the surface of raw materials or forgings, or Read More

Normalization and tempering treatment have different effects on the performance of ZLY250-11.2-2 gear reducer, as follows: The impact of normalization treatment eliminates stress: Normalization treatment can eliminate excessive stress inside the gear, reduce the risk of deformation or cracking caused by internal stress during use, and improve the dimensional stability of the gear. Increase toughness: Normalization can increase the toughness of the gear, so that the gears are not prone to brittle fracture when they bear a certain impact load. For some working scenarios with small impact loads, normalized gears can meet the usage requirements. Improve cutting performance: Normalization can improve the cutting performance of gear materials, make subsequent cutting processing smoother, improve processing efficiency, and reduce tool wear. The hardness of normalized gears is generally in HB163-217, which is conducive to cutting and processing. Refining grains: Normalizing the grains can be refined and evenly organized by heating the gears to a suitable temperature and cooling them in the air. Read More

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.

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 Read More

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 Read More

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 Read More
