Under what circumstances may cause the output shaft of the BLD16-17-18.5KW cycloid reducer to deformThe following are some cases that may cause the output shaft of the BLD16-17-18.5KW cycloid reducer to deform: Overload operation: Excessive torque, such as sudden load change, start-up impact, overload protection failure, etc., which will cause the torsional stress of the output shaft to exceed the yield strength of the material, resulting in the shaft bending or deformation. For example, when the equipment driven by the reducer suddenly becomes stuck and the motor continues to output power, it may cause the output bearing to be subjected to excessive torque. Installation concentricity error: The motor and reducer are not assembled, and the output shaft will bear radial forces from the input end of the reducer. This radial force will force the output shaft to bend and deform for a long time, and the bending direction will continue to change as the output shaft rotates. The greater the concentricity error, the faster the output shaft will deform. Frequent start and stop: During acceleration and deceleration, if the instantaneous torque of the reducer output shaft exceeds 2 times its rated output torque, and this

How to prevent the deformation of the output shaft of the BLD13-35-3KW cycloid pin wheel reducerTo prevent the output shaft of the BLD13-35-3KW cycloid pin wheel reducer deformation, you can start from the following aspects: Reasonable Selection and correct installation Selection: Select the appropriate reducer according to the actual load conditions to ensure that the rated output torque of the selected reducer is greater than the actual maximum working torque required. Generally speaking, the maximum operating torque required by the user should be less than 2 times the rated output torque of the reducer. Accurate installation: During installation, it is necessary to ensure that the output shaft of the reducer is consistent with the shaft of the driven equipment, and calibrate professional tools such as laser centering instruments. The concentricity error should be controlled within 0.05mm/m. At the same time, it is strictly forbidden to use hammers to hit the output shaft of the reducer to prevent excessive axial or radial forces from damaging the bearings or gears. Control operating conditions to avoid overload operation: operate strictly according to the rated load of the reducer, avoid excessive load during startup, stop and operation, and prevent excessive output shaft from being caused.

What are the differences in the requirements for lubricating oil quantity of worm gear reducers of different modelsThe requirements for lubricating oil quantity of different models of worm gear reducers are mainly affected by factors such as center distance, power, etc. There are generally the following differences: According to the center distance: ordinary cylindrical worm gear reducers with a center distance of 50-100mm, the oil filling amount of oil tank lubrication is 0.3-0.8L. When the center distance is 100-160mm, the oil injection volume is 0.8-2L. When the center distance is 160-250mm, the oil injection volume is 2-5L. When the center distance is 250-400mm, the oil injection volume is 5-10L. For arc cylindrical worm reducer, when the center distance is 80-125mm, the oil injection volume is about 0.5-1.5L. When the center distance is 125-200mm, the oil injection volume is 1.5-3L. When the center distance is 200-315mm, the oil injection volume is 3-8L. Estimation by power: For single-stage transmission reducers, you can refer to each transmission

How to determine the working environment temperature of WPA250-50-C worm gear reducerThe method of judging the working environment temperature of WPA250 - 50 - C Worm gear reducer is as follows: View the equipment manual: Refer to the product manual or technical information of the reducer, the recommended working environment temperature range will usually be clearly given. Generally, the working environment temperature of WPA series Worm gear reducer is -40℃ to 40℃. Measure with a thermometer: near the reducer installation position, select several representative points, such as close to the reducer body, vents, etc., and use an ordinary thermometer or electronic thermometer to measure to obtain the approximate value of the ambient temperature. Observe the environmental conditions: If there is a clear heat source in the surrounding environment, such as close to a furnace, heating equipment, etc., or in direct sunlight, the working environment temperature may be higher; if it is in a cold outdoors and no heating measures, the temperature may be lower. At the same time, pay attention to the ventilation of the environment. Good ventilation helps heat dissipation, which can make the ambient temperature relatively low and stable

Introduction to the maintenance method of the CFD250 cooling tower fan reducerThe maintenance methods of CFD250 cooling tower fan reducer are as follows: Maintenance of lubrication system. Check the oil level regularly: Check the oil level at least once a week to ensure that the oil level is around 1/2 of the oil standard. If the oil level is found to be too low, you should add N320 industrial gear oil or No. 0 lithium-based grease gear oil that meets the requirements in time. Change oil by cycle: new reducer runs After the run-in period of 150 - 300 hours (7 - 14 days) new oil needs to be replaced, and a second oil change is performed after use until 3 months. After that, the reducer that has been continuously working for a long time can be 6-8 Change the oil once a month, and change the oil once a month if the reducer works for no more than 8 hours a day. When changing oil, it should be carried out at the operating temperature of the reducer to facilitate the discharge of old oil. Oil product inspection: Before refueling or changing oil, check the quality of the oil. If the oil is turbid, impurities, discoloration or odor, it means that the oil has deteriorated.

How much impact does the reducer stage have on transmission accuracy and stability?The number of stages of reducers has the following impact on transmission accuracy and stability: The impact on transmission accuracy Error transmission and accumulation: Theoretically, the more stages, the longer the transmission chain, the more links of error transmission, and the more likely it is to lead to a decrease in accuracy. Because each stage of gear transmission will have certain manufacturing errors, installation errors, and gear meshing clearance, etc., these errors will gradually accumulate in multi-stage transmission. For example, if the accuracy of a single-stage reducer can be achieved If the error is within 1 arc minute, the accuracy of the two-stage reducer may drop to within 3 arc minutes due to the superposition of errors. Error Average and Compensation: In some high-precision reducer designs, the transmission error can be averaged and compensated by reasonably designing the parameters and accuracy levels of multi-stage gears. For example, when using a multi-stage planetary reducer, by optimizing the distribution of planetary wheels and gear parameters at each level, the errors at each level can be offset to a certain extent, which can improve the transmission accuracy and satisfy the needs of precision machine tools and machinery.

What are the common damage forms of the output shaft of XLD22-71-2.2KW cycloid pin wheel reducerXLD22-71-2.2KW 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.

How to repair the output shaft of XLD27-59-3KW cycloid pin wheel reducer if it is wornThe 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

How much impact does the application of gear shape modification technology have on the cost of reducers?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

Selection standards for single-stage hard toothed ZDY series cylindrical gear reducer lubricating greaseThe 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.
