How to ensure the firmness of the installation foundation of the NGW73-224 planetary gear reducer

To ensure the firmness of the installation foundation of the NGW73-224 planetary gear reducer, you can refer to the following methods:

• Choose a suitable installation position : The reducer should be installed in a horizontal and stable position, with the inclination not exceeding 10° to avoid the impact of vibration on the performance of the reducer. The installation surface should be strong and durable, able to withstand the weight of the reducer and load, while ensuring sufficient space is available for heat dissipation and maintenance.

• Making a solid foundation : The foundation should be made according to the requirements of the design drawings to ensure its accurate size. The material of the foundation can be concrete or metal. The thickness of the concrete foundation should generally be ≥200mm, and the hardness of the metal base plate should be ≥HB200. The flatness error of the foundation surface should be ≤0.1mm/m to ensure that the reducer base is closely fitted with the foundation.

• Correct fixing of the reducer : Use appropriate bolts to fix the reducer on the foundation. The specifications of the bolts should be strictly selected according to the model and installation requirements of the reducer. When tightening bolts, the 'three-step tightening method' should be used, namely, initial twisting (50% rated torque) → repeated twisting (80%) → final twisting (100%), and each step is separated by 10 minutes to release material stress. You can also use the method of tightening the bolts in stages in diagonal lines, and the final torque needs to be applied according to the manufacturer's marked value. To prevent bolts from loosening, thread glue or spring washer can be used.

• Conduct foundation acceptance : Before installing the reducer, the foundation must be inspected to check whether the flatness, dimensions, etc. of the foundation meet the requirements, and ensure that the foundation can withstand the weight of the reducer and vibration during operation. Only after passing the acceptance can the reducer be installed.
