The core of reducing the vibration value of the NGW52-6 planetary gear reducer frame is to eliminate force imbalance, optimize assembly accuracy, solve component defects , and deal with it in a targeted manner from the four dimensions of installation, components, operation, and structure to quickly stabilize the vibration level.
1. Optimize installation and assembly accuracy (basic and efficient)
Re-level the installation surface to ensure that the flatness deviation is ≤0.03mm/m, and use spacers to adjust evenly to avoid tilting the machine base.
Tighten the anchor bolts evenly according to the specified torque (refer to the equipment manual), install anti-loosening washers, and retighten regularly to prevent loosening.
Calibrate input/output shaft coaxiality, control deviation ≤0.02mm, use elastic connection (such as plum blossom coupling) to absorb the impact caused by installation deviation.
Check the mating surfaces of the machine base, end cover, and bearing seat to remove burrs and debris to ensure tight fit without gaps and avoid shock and vibration during operation.
2. Repair/replace failed internal components (reduce vibration sources from the source)
Check the meshing status of the planet gear, sun gear, and internal ring gear. If there is wear, pitting, or excessive clearance, replace or grind the gears in time to ensure meshing accuracy.
Replace worn and noisy bearings, replenish or replace lubricating oil that meets the model (such as No. 220 gear oil), ensure that the oil level reaches the standard, and reduce transmission friction and vibration.
Check whether the planet carrier is deformed and whether the planet shaft is worn. If there is an eccentricity problem, repair or replace the planet carrier to ensure that the planet wheels run concentrically.
3. Optimize operating conditions and external environment
It is strictly prohibited to operate overloaded, avoid frequent starts and stops and severe impact loads. If necessary, install an overload protection device or buffer mechanism.
Check the risk of resonance by adjusting the equipment speed or adding rubber damping pads or spring dampers at the bottom of the machine base to change the natural frequency and avoid the resonance range.
Clean the debris around the machine base to ensure smooth heat dissipation and avoid changes in the fitting clearance of components caused by high temperatures, which may indirectly cause vibration.
4. Strengthen the structural rigidity of the machine base (for scenarios with weak structures)
If the machine base has uneven wall thickness and stress concentration problems, reinforcement ribs can be installed around the bearing seat and near the anchor bolt holes, or reinforced with covered steel plates to improve structural rigidity.
If there are hidden cracks or traces of repairs on the machine base, non-destructive testing should be performed again to thoroughly repair the cracks and eliminate stress to avoid cracks causing resonance during vibration.
