In which situations is it necessary to redo the installation base for the NGW103-355 planetary reducer?

The following are some situations that require rework on the installation foundation of NGW103-355 planetary gearbox:

Insufficient basic strength: If the concrete strength of the installed foundation does not meet the design requirements, during the operation of the reducer, the foundation may not be able to withstand the weight of the reducer and the vibration and impact loads during operation, resulting in problems such as cracks and sinking. In this case, the foundation needs to be reworked and a concrete foundation that meets the strength requirements needs to be poured again.

Basic flatness deviation: The installation of NGW103-355 planetary gearbox requires a high flatness of the foundation. If the surface flatness error of the foundation is too large, it will cause the gearbox to tilt and experience uneven force after installation, which will affect the normal operation and service life of the gearbox. When the flatness exceeds the allowable deviation range, the foundation surface needs to be re polished or repaired to meet the specified flatness requirements.

Excessive deviation in basic dimensions: The external dimensions of the foundation, the position and size of the anchor bolt holes, etc. do not meet the installation requirements of the reducer. For example, the deviation in the position of the anchor bolt holes is too large, causing the reducer to be unable to be installed correctly, or the length, width, and height dimensions of the foundation do not meet the design requirements, affecting the installation space and stability of the reducer. At this time, the foundation needs to be reworked to correct the dimensional deviation.

Foundation settlement: After the installation of the reducer, if uneven settlement of the foundation is found, it will cause the shaft system of the reducer to deviate, the gear meshing state to deteriorate, and abnormal vibration and noise will be generated. In severe cases, it may even cause damage to the reducer. Once it is determined that there is a settlement issue with the foundation, measures need to be taken to reinforce or rebuild the foundation to eliminate the impact of settlement on the gearbox.

Connection problem between foundation and equipment: When the foundation anchor bolts are loose or broken, or when the connection surface between the foundation and the reducer is loose or has gaps, it affects the stable installation of the reducer, resulting in increased vibration during operation. It is also necessary to rework the foundation by reinstalling the anchor bolts or repairing the connection surface to ensure a firm and reliable connection between the reducer and the foundation.
