What impact will foundation settlement have on NGW92-31.5 planetary gear reducer

The foundation settlement may have the following impacts on the NGW92 planetary gearbox:

Causing increased vibration and noise: Foundation settlement can cause the installation plane of the gearbox to no longer be horizontal or to tilt, damaging the coaxiality and perpendicularity between the gearbox, motor, and load equipment. This will cause additional radial and axial forces on transmission components such as gears and shafts during operation, resulting in unbalanced loads and exacerbating the vibration of the gearbox. The increase in vibration will also increase the impact and friction during gear meshing, resulting in greater noise.

Accelerated gear and bearing wear: Due to foundation settlement, the installation accuracy of the reducer is damaged, and the meshing state between gears changes, no longer ideal tooth surface contact, which may result in biased load, excessive local contact stress, and other situations. Long term exposure to this abnormal meshing state can result in wear, pitting, bonding and other forms of failure on the gear teeth, shortening the service life of the gear. At the same time, bearings can also bear greater pressure and friction due to additional loads and vibrations, leading to increased wear on the rolling elements and raceways of the bearings, and even fatigue peeling, jamming, and other faults.

Impact on transmission efficiency: Component wear and changes in installation accuracy caused by foundation settlement can increase the energy loss of the gearbox during transmission. For example, poor gear meshing can lead to poor power transmission and generate additional frictional heat; Bearing wear will increase rotational resistance, which will reduce the transmission efficiency of the gearbox and cause energy waste.

Causing seal failure and oil leakage: When the gearbox is installed unevenly, its casing may deform, which can cause uneven compression and stretching of the seals, leading to a decrease in sealing performance. In addition, the intensification of vibration can also make the seals more prone to wear and aging, leading to the leakage of lubricating oil from the seals. Oil leakage not only pollutes the working environment, but also leads to insufficient lubricating oil inside the gearbox, affecting its lubrication and heat dissipation effects, further exacerbating component wear.

Causing safety hazards: If the foundation settlement is severe, it may cause the fixing bolts of the reducer to loosen or even break, resulting in displacement or falling of the reducer, posing a serious safety threat to surrounding equipment and personnel. Moreover, severe wear and damage to the internal components of the gearbox may also lead to sudden transmission interruption or abnormal power output, affecting the normal operation of the entire equipment system and causing production safety accidents.
