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.

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

BWD45-87-7.5KW The output shaft of the cycloid reducer may be caused by the following overload conditions: Selection improper results in long-term overload: If various factors in actual work are not fully considered at Selection, the rated output torque of the selected reducer does not match the actual required torque, it may cause the reducer to be in a long-term overload state. For example, in some working scenarios where frequent start, braking or large impact loads are present, if only the conventional average load is Selection and sufficient torque margin is not reserved, then even under normal working loads, the reducer may fail the output shaft due to the inability to withstand these additional impacts. Equipment failure causes sudden increase in load: During operation, some failures may occur, resulting in sudden increase in load of reducer, exceeding its ability to withstand. For example, the mechanical components of the driven equipment are stuck or stuck, causing the output shaft of the reducer to rotate when the output shaft of the reducer is rotated. Read More

To determine whether the output shaft break of the cycloid reducer is caused by overload, you can start from the following aspects: Check the fracture shape: Plastic deformation characteristics: If the output shaft material is a plastic material, there will generally be obvious plastic deformation when overloaded and broken, such as the diameter of the shaft may become partially thinner and there will be necking near the fracture. Fracture texture: brittle fracture caused by overload, the fracture roughness is relatively consistent, there are obvious marks on the surface, and the marks point to the origin of the damage; if the plastic material is under very rapid and severe overload, it may also show a failure mode similar to the brittle material, the crack may show a 45° inclination, and the keyways are significantly deformed. Analyze the operation records and working conditions: Load changes: Check the equipment operation records to understand whether the load borne by the reducer suddenly increases and exceeds the rated load before the output shaft breaks, such as whether additional heavy objects are suddenly added to the transmission system, or working resistance Read More
