BLEY5527-289-15KW Oil leakage at the sealing of the cycloid pin wheel reducer can be quickly solved by the following methods: Use sealant or leak plugging agent: If it is a slight oil leakage, apply an appropriate amount of high-temperature resistant sealant to the sealing surface or bolt connection to enhance the sealing effect. Special lubricant leak plugging agent can also be added. This additive can form a temporary sealing film at the oil leakage point, which plays an emergency leak plugging role. Adjust the oil level: Check the oil level of the reducer. If the oil level is too high, excess lubricating oil must be released through the oil drain hole to keep the oil level at the center line of the oil standard to reduce oil leakage caused by excessive oil level. Clean the vent holes: Blockage of the vent holes will increase the pressure inside the reducer, causing oil to seep out of the seal. Therefore, the ventilation holes should be cleaned in time to ensure that they are unobstructed, so that the internal pressure of the reducer is balanced with the external pressure. Tightening bolts: Check whether the bolts at the seal are loose. If they are loose, they need to be twisted evenly in multiple diagonal orders. Read More

The sealing device of the output shaft of the cycloid pin wheel reducer mainly prevents lubricating oil leakage through the following methods: Oil seal seal: Usually a skeleton oil seal is used, and its cross-sectional shape is J-shaped. It uses the elasticity of the lip-shaped structural part and the clamping force of the coil spring coil to make the lip-shaped part close to the shaft surface. The sealing ring is equipped with a metal frame, which achieves axial fixation by the cooperation of the periphery and the hole. If it is mainly for oil sealing, the sealing lip should face the bearing, thereby preventing the lubricant from leaking out of the gap between the output shaft and the end cap. Oil return tank design: A oil return tank tilted into the machine in the center of the lower tile of the bearing seat, and a notch is also made at the straight opening of the end cover, which faces the oil return tank. In this way, the excess lubricant that is thrown by the gear on the bearing will flow back to the oil tank in a certain direction through the notch and the oil return tank to avoid the accumulation of lubricant at the shaft seal, thereby reducing the possibility of leakage. Sealant auxiliary: on the end cover and box of the reducer Read More

Methods for detecting the settlement of the base of the NGW-L122-90 planetary reducer 1. Preparation work before settlement detection Tool preparation requires the use of a laser level (accuracy ≥0.02mm/m) or a precision level to measure in the longitudinal and transverse direction of the base (the spacing between measurement points ≤500mm). Prepare a feeler gauge (0.02-1mm specification) and a dial meter for measuring local gaps and deformations‌. ‌Confirm the status of the base to remove oil stains and rust on the base surface, ensure that the measurement surface is clean, and check whether the anchor bolts are loose or deformed. 2. Settlement detection steps ‌static flatness measurement‌. Place the level in the four corners and center area of ​​the base to record the horizontal error. If it exceeds 0.1mm/m (high-precision scenarios are recommended to ≤0.05mm/m), it needs to be adjusted or repaired. Use a feeler gauge to check the fitting gap between the reducer base and the base. The insertion depth of the feeler gauge on all fitting surfaces shall not exceed 10mm and 0.05. Read More

Material selection for improving the bearing capacity of the NBD710-35.5 planetary reducer base 1. ‌Plate material optimization‌‌ Ductile iron (QT500-7/QT600-3): Ductile iron has high strength (tentic strength 500-700MPa) and excellent shock absorption performance (shock coefficient ≥0.15), which can effectively reduce the impact of gear meshing vibration on the base, and is suitable for heavy-load conditions. Advantages: Good casting performance, cost 30%-50% lower than cast steel, and can further improve rigidity through reinforcement design. ‌Casted steel (such as ZG270-500): Suitable for extreme heavy load or impact conditions, with tensile strength ≥500MPa, but attention should be paid to stress relief treatment after welding or machining. 2. Reinforced key connector material‌‌ anchor bolts and connection bolts‌: High-strength alloy steel (such as 40Cr or 42CrMo) is used, and tempered (quenching + high-temperature tempering) Read More

WS150-16-1 The box structure of the worm gear reducer has the following characteristics: the overall structure: a split structure consisting of the upper box cover and the lower box seat, and the split surface is driven by the axis of the worm gear. This structure facilitates the installation and disassembly of shaft system components. During installation, components such as worm gear, worm, shaft and bearing can be assembled on the box seat, and then cover the box cover and fasten the box cover and the box seat together with bolts. Material selection: Gray cast iron is usually used as the material of the box, such as HT250 or HT300 wait. Gray cast iron has good casting properties and can be easily cast into various complex shapes, meeting the structural requirements of the box. At the same time, it also has excellent shock absorption performance, which can effectively absorb the vibration and noise generated by the reducer during operation, ensuring the smooth operation of the reducer. In addition, the cutting performance of gray cast iron is also good, making it easier to fit the box Read More

WS300-23.5-II The transmission efficiency of the worm gear reducer is affected by a variety of factors, as follows: Worm lead angle: The larger the lead angle, the smaller the sliding friction between the worm and the worm gear tooth surface, and the higher the transmission efficiency. Generally speaking, the lead angle is Between 3.5°-33°, if it exceeds 30°. Although the efficiency will be further improved in theory, the processing difficulty will increase significantly. In addition, the lead angle of the multi-head worm is larger than that of the single-head worm, so under the same conditions, the transmission efficiency of the multi-head worm (such as double-head and triple-head) is higher, but the transmission ratio will be reduced accordingly. Material pairing and friction coefficient: Usually the worm is made of steel, such as medium carbon steel or medium carbon alloy steel, while the worm gear is made of bronze, such as cast tin bronze or cast aluminum bronze. This combination of steel worm and bronze worm gear can effectively reduce the coefficient of friction, reduce wear, and thus improve transmission efficiency. In addition, the worm is inserted into Read More
