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

There are many reasons why the WB100-D-23-0.55KW micro cycloid reducer may fail. The following are some common factors: 1. Lubrication problem Inadequate lubrication: Insufficient lubricating oil will increase friction between parts and parts, which will not be well protected and heat dissipated, thereby accelerating wear and causing failures, such as gear wear, bearing damage, etc. Poor oil quality: The lubricant used is of poor quality, or the lubricant has not been replaced for a long time, and contains impurities, moisture, etc., which will reduce the lubricating effect, increase the wear of parts, and may also cause lubricating system to be blocked. Lubricant oil Selection error: If the selected lubricant does not meet the requirements of the reducer, such as inappropriate viscosity, and cannot form a good lubricant film on the surface of the parts, it will also affect the normal operation of the reducer. 2. Overload operation: When the load borne by the reducer exceeds its rated load, internal gears, bearings and other components will bear excessive pressure. Read More

There are usually some common standards for the grease replacement cycle and method of micro cycloid reducers, but please refer to the product manual for details. The following is the relevant content about grease replacement for WB1285-LD-2065-0.37KW/4 micro cycloid reducer: Replacement cycle General situation: According to the common cycloid reducer usage specifications, the newly purchased reducer should undergo the first grease replacement after initial operation of 300-600 hours. After that, under normal use conditions, that is, working for no more than 10 hours a day and the ambient temperature and other conditions are more suitable, it is recommended to replace the grease every 6-12 months. Special circumstances: If the reducer runs more than every day 10 hours, or the working environment temperature is higher (more than 40℃), lower (less than - 15℃), and in harsh environments such as high dust and high humidity, the replacement cycle of grease should be shortened.
