The 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 Read More

The 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 Read More

The 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. Read More

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.

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
