XLD22-71-2.2KW Common damage forms of the output shaft of the cycloid pin wheel reducer are as follows: Wear bearing position wear: The part where the output shaft and the bearing are fitted will wear due to long-term operation, poor lubrication, improper matching clearance, etc., resulting in a decrease in the matching accuracy, affecting the performance of the reducer, causing problems such as jumping and vibration during operation of the output shaft. Keyway wear: Keyway is used to connect the output shaft to external loads, such as couplings, gears, etc. During the torque transmission process, the friction and impact between the keyways will gradually wear out, and the keyway width will increase, resulting in loose fit between the keyways and the keyways and inability to effectively transmit torque. Deformation Bending Deformation: When the radial force that the output shaft of the reducer is subjected to is too large, such as the concentricity deviation between the output shaft and the load during installation, and the load has a large eccentricity, etc., the output shaft will be bending and deformed. The output shaft after bending and deformation can aggravate the wear of the bearing and even cause gear meshing. Read More

The wear of the output shaft of the XLD27-59-3KW cycloid pin wheel reducer can be repaired in the following ways: Analyzing and determining the wear part: first remove the relevant components, such as removing the output shaft end cover, coupling, etc., take the output shaft out of the reducer, carefully check the wear of the output shaft, clarify whether it is the wear of the bearing position, the keyway or other parts, measure the size and degree of the wear, and provide a basis for subsequent maintenance. After-welding processing of bearing positions: If the wear is not too serious, the repair welding method can be used. First clean, remove oil and rust the wear parts, then repair welding with appropriate welding rods, and then turn, grind and other processing to restore the size of the bearing position to the specified accuracy, and the surface roughness must also meet the requirements. Brush plating or spraying: For situations where the wear amount is small, brush plating is a better method. It can coat a layer of metal on the worn surface to restore size and accuracy. Thermal spraying technology can also be used to transfer metal or Read More

The impact of the application of gear shape refining technology on reducer cost is relatively complex, and it needs to be considered in a variety of factors, as follows: Material cost: Under normal circumstances, gear shape refining technology itself will not directly lead to an increase in material cost. However, in order to better exert the effect of shape-touching technology, there may be higher requirements for material performance, such as the need to use steel with higher strength and toughness, or stricter standards for the heat treatment process of the material, which may increase material costs. But from another perspective, the shape-touching technology can improve the gear load-bearing capacity, so that the reducer may use smaller gears to achieve the same transmission function under the same working conditions, thereby reducing the amount of material and reducing material costs. Processing cost: Equipment and process cost: Gear shape modification requires the use of special processing equipment and processes, such as high-precision grinders, honing machines, etc., and the purchase and maintenance costs of these equipment are relatively high. And repair Read More

The selection criteria for cylindrical gear reducer lubricating grease mainly consider the following aspects: 1. Load pressure: Select based on the actual working load and pressure of the gear. For heavy-load cylindrical gear reducers, greases with high base oil viscosity and high thickener content should be selected, and greases containing extreme pressure additives or fillers (such as molybdenum disulfide or graphite) should also be selected; for gears with medium and low loads, greases with short fiber structure of No. 2 consistency soap fibers and medium viscosity base oil should be generally selected. 2. Temperature characteristics: High temperature environment: If the reducer works in a high temperature environment, the grease must have high temperature resistance. You should choose greases with high drop point, good oxidation resistance and small evaporation losses, such as composite lithium-based grease, polyurea grease, etc. Generally speaking, the maximum service temperature should be lower than the drop point by 10-20℃ (mineral oil-based grease) or 20-30℃ (synthetic grease). Low temperature environment: In low temperature environment, good low temperature fluidity and start-up should be selected. Read More

The price gap between hard tooth surface and soft tooth surface reducer is mainly affected by the following factors: Material cost Gear material: The gears of hard tooth surface reducer usually use high-quality alloy steel, such as 20CrMnMo, 20CrNiMo, etc. These materials have high strength, high wear resistance and good heat treatment performance. The gears of soft-tooth surface reducers are commonly made of ordinary steel such as 45 steel and 35SiMn, and the material price is relatively low. Box material: Because the hard-toothed reducer needs to withstand high load and impact force, the box is often forged with cast iron or high-strength cast steel. The box material of the soft-toothed reducer is generally ordinary cast iron, and the former has higher material costs. Manufacturing process processing accuracy: The hard tooth surface reducer requires high-precision processing to ensure accuracy indicators such as tooth shape and tooth direction. Advanced processing equipment and precision processes are required, such as grinding teeth, shaving teeth, etc., and the processing cost is high. The machining accuracy requirements for soft tooth surface reduction machine are relatively low, and conventional processes such as hobbing and tooth insertion are adopted. Read More

The maintenance costs of hard-tooth surface reducers and soft-tooth surface reducers are as follows: Maintenance cycle: The gears of the hard-tooth surface reducers have high hardness and good wear resistance. Under normal working conditions, their wear speed is relatively slow and the maintenance cycle is long. Generally, it can run for a long time before a comprehensive inspection and maintenance is required. Because the tooth surface of soft tooth surface is softer, it is more likely to cause wear and other problems. In order to ensure its performance and service life, inspections and maintenance are required more frequently. For example, inspections may be required every short time (such as several months), while hard tooth surface reducers may need to be inspected to the same level for one year or more. Component replacement cost: The gears and other key components of the hard-toothed reducer use high-quality alloy steel and undergoes complex heat treatment processes, which is costly. Therefore, once the gears and other components need to be replaced, the cost is relatively expensive. However, due to its good durability, the replacement frequency of parts is relatively high under normal use. Read More
