• Expand and introduce the box structure of WS150-16-1 worm gear reducer

  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

• What factors affect the transmission efficiency of WS300-23.5-II worm gear reducer

  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

• Introduction to a cause of the failure of the WB100-D-23-0.55KW miniature cycloid reducer

  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.

• What are the disadvantages of arc gears compared to involute gears in high-speed transmission

  The main disadvantages of arc gears in high-speed transmission: 1. It is difficult to process and has a higher cost. The tooth profile accuracy of arc gears has a great impact on high-speed performance, but its processing technology is much more complicated than involute gears: Special equipment depends on: special arc gear milling cutters and grinders (such as Y3180 arc gear milling machine), and processing equipment cannot be used for involute gears, and the equipment investment cost increases by 50% to 100%. Strict accuracy control: The arc tooth profile 'tooth arc radius''tooth drum volume' of the arc tooth profile needs to be strictly matched (small deviation at high speed will cause a sudden increase in contact stress), the processing tolerance needs to be controlled at IT5~IT6 levels (the high-speed stage of involute gears is usually IT6~IT7 levels), the machining working hours increase by 30%~60%, and the final gear manufacturing cost is 40%~80% higher than that of involute gears. 2. Installation requirements are extremely high for neutrality and poor fault tolerance. The installation deviation of gears in high-speed transmission (

• What are the differences in the installation methods of output shafts of cycloid pin wheel reducer of different models

  The installation method of the output shaft of the cycloid pin wheel reducer of different models may have the following differences: installation method and alignment requirements for horizontal installation: such as XWD/BWD series horizontal cycloid pin wheel reducer, the output shaft is parallel to the ground, and it must be installed on a horizontal basis without vibration and solidity during installation. The inclination of the axis line shall not be greater than ±15°. During installation, it is necessary to ensure that the output shaft is consistent with the axis of the driven mechanical equipment. It is usually necessary to connect with a coupling, which requires high centering requirements, otherwise it may lead to reduced transmission efficiency or equipment damage. Vertical installation: Some models are flange vertical cycloid pin wheel reducer, with the output shaft vertically downward and can be installed horizontally, but if the output shaft needs to be installed upward, special instructions are required when ordering. This installation method requires high sealing of lubricating oil to avoid leakage. Special installation: Some reducer models with torque arms, such as FA47/T, output shaft through torque arms with drive and load

• What should I pay attention to when adding lubricating oil for different types of cycloid pin wheel reducers?

  Special precautions for different types of cycloid pin wheel reducers need to be adjusted in a targeted manner according to the differences in installation methods and structural characteristics to avoid adaptation problems caused by 'general operation': 1. The fuel tank of the horizontal cycloid pin wheel reducer (most common, such as X and B series) is 'side-mounted', and the oil level is greatly affected by the installation level. The core attention is 'horizontal degree and oil level': Installation level check: Before refueling, you need to use a level to detect the level of the fuselage (required ≤0.1mm/m). If the fuselage is inclined (such as one side is high and the other side is low), it will cause the oil level in the fuel tank to 'one side is high and one side is low'. The base gasket must be adjusted first to ensure level before refueling; oil outlet anti-blocking: The oil outlet of the horizontal model (connected to the lubricating oil pump) is located at the bottom of the oil tank. If impurities are mixed during refueling, it is easy to block the oil outlet, causing the lubricating system to break oil- It is recommended to run for 5 minutes after refueling and observe the bearing seat temperature (

• Comparison of service life of hard tooth surface and soft tooth surface reducer

  The service life difference between the hard tooth surface reducer and the soft tooth surface reducer is due to the essential difference between the tooth surface hardness, load-bearing capacity, and wear resistance/fatigue resistance. It is also affected by external factors such as working conditions and maintenance level. Essential difference: The hard tooth surface achieves higher load-bearing capacity and failure resistance through surface hardening process, which is the core reason for its longer life; life comparison: Under the same working conditions, the life of the hard tooth surface is 1.5-2 times that of the soft tooth surface, and the advantages are more significant under heavy/hard working conditions; key premise: The life advantage of the hard tooth surface depends on 'correct Selection (match load), standardized installation (guaranteed centering), high-quality lubrication (cleaning adaptation)', otherwise the life may be shortened due to bearing failure, tooth breakage and other problems; Selection Logic: Life expectancy requirement >10 years, complex working conditions → hard tooth surface; life expectancy requirement 5-8 years, simple working conditions → soft tooth surface, balance cost and performance.

• How to determine whether the alignment of the multi-stage reducer is good

  To determine whether the centering of the multi-stage reducer is the core of detecting the relative position deviation of the axis of the input shaft, intermediate shafts at each stage, and output shaft (including parallelism and coaxiality), as well as the neutrality between the shaft and the coupling (or motor shaft). Poor centering will lead to gear bias load, bearing overheating, and vibration abnormalities, which will shorten the life in the long run. The following are three aspects: 'Basic inspection (quick judgment)''Professional inspection (accurate quantization)''''Centering bad characteristics' provide ground-based judgment methods, covering on-site operation and professional tool application scenarios: 1. Basic inspection: No professional tools are required, quickly identify obvious bad centering bad is suitable for daily inspection or preliminary investigation. Through 'see, listen, touch, and test' to judge abnormalities, low operating threshold: 1. Observe the appearance and component status Gear meshing traces: Open the reducer observation hole (need to shut down and power off), and check the meshing contact spots of gears at all levels (can be applied to assist in observation): Good centering: Connect
