ZSC400-49.86-2 is a coaxial soft tooth surface reducer. The tilted oil pool design is its core design to adapt to the structural characteristics and working conditions requirements, which is in line with ZSC The gear and shaft system layout of the series coaxial transmission is optimized for the core needs of soft tooth surface gear lubrication, sealing, oil drainage, etc. Compared with the flat oil pool design, it has significant advantages in lubrication effect, oil drainage and cleaning, seal protection, space adaptation, operation stability, etc., and is suitable for the installation and working conditions of this model. The specific advantages are as follows: 1. Optimize the gear meshing lubrication effect and adapt to the coaxial transmission layout. This model has a coaxial structure, input/ The output shaft is coaxially arranged, and the gears are distributed in a stepped manner. The tilted oil pool can accurately adjust the oil level, so that gears of different diameters can be immersed in appropriate oil depths (large gears are slightly immersed in oil, and small gears are moderately immersed in oil). This prevents some gears from being immersed in oil too deeply due to a single oil level in the flat oil pool (oil churning loss). Read More

If an abnormality occurs during the trial operation of the ZQ250-31.5-4 gear reducer, it should be stopped immediately for investigation. The root cause of the problem should be systematically diagnosed according to the principle of 'from outside to inside, from simple to complex' and dealt with in a targeted manner to avoid equipment damage or safety accidents. 1. Immediate safety measures: Cut off the power supply: Cut off the power supply to the motor and control system immediately, and hang a 'no closing' warning sign to prevent misstarting. ‌Release energy‌: Confirm that the brake has been powered off and released, the inverter has completed discharge, and the equipment is completely stationary. ‌Record Phenomenon‌: Record abnormal phenomena (such as abnormal noise, vibration, temperature rise, stuck, etc.) in detail to facilitate subsequent analysis. 2. Common exception types and processing steps 1. Possible causes of abnormal noise or abnormal noise include poor gear meshing, bearing damage, impurities in the lubricating oil, or improper gear clearance. Check the condition of the lubricating oil: take a sample to see if metal shavings, moisture or impurities are mixed in, and replace the gear with one that meets the standard if necessary. Read More

Professional tools are required to replace the bearings of the TY125-40-4KW shaft-mounted reducer to ensure the accuracy and safety of disassembly and assembly, and to avoid damage to the shaft and bearing seat. The following is a list of recommended tools and operating points: 1. Core disassembly and installation tools ‌Hydraulic puller (three-claw or four-claw) ‌ is used to safely disassemble bearings with interference fit. It is recommended to use a hydraulic puller with a pressure gauge, which can control the pulling force within a reasonable range and prevent damage to the shaft end. For the shaft diameter of TY125 model (usually Φ50-Φ70mm), specifications above 10 tons are recommended. ‌Induction heater‌When installing a new bearing, an induction heater is used to heat the inner ring of the bearing to 80–120°C. The principle of thermal expansion and contraction is used to achieve stress-free assembly and avoid knocking damage to the raceway. ‌Torque wrench (accuracy ±3%)‌Used to tighten end cover bolts and lock nuts to ensure that the specified torque value is reached (for example, M24 bolts require 320N·m) to prevent loosening or overload damage to the nuts.

After replacing the seals of the FAF47-36.34-1.5KW gear reducer, it is recommended to perform a moderate running-in operation to ensure the stability of the cooperation between the sealing system and the moving parts and reduce the risk of leakage. Although the main purpose of running-in is usually for transmission components such as gear pairs and bearings, after the seal is replaced, the surface contact state between the seal ring and the shaft changes, resulting in microscopic misfit. Short-term low-load operation can help the seal gradually adapt to the rotation state of the shaft and improve the sealing effect, which is especially critical under high temperature, high humidity or vibration conditions. Operation suggestions during the running-in period: ‌1. Control the load‌: It is recommended that the working load during the running-in period should not exceed 85% of the rated load to avoid micro-deformation of the shaft or uneven sealing compression due to overload. ‌2. Monitor temperature rise and leakage‌: Check the box temperature and sealing area for oil leakage every 30 minutes in the early stage of operation. If there is abnormal temperature rise or oil dripping, stop the machine immediately for investigation. ‌ Read More

The alignment accuracy of the WHT80-8-I arc cylindrical worm gear reducer is directly related to the stability of equipment operation, bearing life and sealing reliability. Especially under high load conditions such as metallurgy and lifting, small deviations may cause vibration, temperature rise, oil leakage and even gear damage. It must be strictly controlled through scientific methods and professional tools. 1. Key preparations before alignment ‌ Cleaning and inspection ‌ Clean the oil, rust and burrs on the input/output shaft end and the inner hole of the coupling to ensure that there are no foreign objects on the mating surface that affect the coaxiality. ‌Tools in place‌Prepare laser alignment instrument or precision dial indicator (laser recommended, higher accuracy), feeler gauge, torque wrench, level, etc. It is strictly prohibited to rely solely on visual inspection or rough alignment with a ruler. ‌Preliminary Positioning‌ Lift the reducer into place and pre-tighten the anchor bolts diagonally to keep the base close but leave room for fine adjustment. 2. Precise alignment operation steps ‌ Coupling connection ‌ Connect the motor and reducer through an elastic coupling. Read More

When the WHX125-40:1 worm gear reducer operates in high-load scenarios such as metallurgy and lifting, the quality of foundation fixation and leveling directly determines the stability, transmission accuracy and service life of the equipment. If the foundation is unstable or the level is out of tolerance, it can easily lead to increased vibration, eccentric bearing loading, seal leakage and even gear damage. High-quality installation must be achieved through systematic control. 1. Foundation preparation: Ensure load-bearing rigidity and stability. Basic material selection. It is recommended to use high-strength concrete (above C25) or steel structure platform to ensure that it can withstand the weight of the reducer and the impact load during operation, and avoid stress concentration in the box due to foundation settlement or deformation. ‌Surface flatness control‌The installation surface flatness error should be ≤0.1mm/m. Use steel flat gaskets for leveling. It is prohibited to use easily compressible materials such as wooden boards or rubber pads as leveling media. ‌Reserve anchor holes and oil drainage space ‌The position of the anchor bolt holes must match the base of the reducer while ensuring drainage Read More
