What are the requirements for the installation foundation plane of NMRVF63-40-0.75KW reducer with foot installation method

The core requirements for the NMRVF63-40-0.75KW reducer installed on the foot are that the installation foundation plane should be flat, firm, and rigid to meet the standards. The specific requirements are as follows:
1. Flatness of the plane

The flatness error of the basic plane should be ≤ 0.1mm/m to avoid local protrusions or depressions.

The installation surface needs to be cleaned thoroughly, without oil stains, iron filings, debris, etc., to prevent loose contact.

2. Basic rigidity and strength

The foundation needs to have sufficient rigidity and operate without significant deformation or vibration.

Concrete, cast iron, or thick steel plates are preferred as basic materials, and reinforced brackets can be used with small equipment.

If installed on a lightweight rack, the rack needs to be reinforced to avoid resonance.

3. Levelness requirements

After the installation of the reducer, the horizontal error of the machine body should be ≤ 0.2mm/m (both axial and radial must meet the requirements).

It can be detected by a level and corrected for deviation with the help of adjusting shims. The shims need to be fully attached to the mounting feet.

4. Installation holes and fixing requirements

The installation hole position on the basis needs to be accurately matched with the reducer foot hole, with a hole diameter slightly larger than the fixed bolt diameter.

High strength bolts are used for fixation, and the bolts need to be tightened to the specified torque to prevent loosening during operation.

When multiple units are installed side by side, the foundation planes of each reducer need to maintain the same horizontal height.

5. Other auxiliary requirements

The foundation needs to reserve ventilation space to avoid poor heat dissipation of the gearbox.

The installation surface needs to have anti-corrosion ability, which can be treated by painting, galvanizing and other methods.

When used outdoors for a long time, waterproof measures should be taken for the foundation to prevent water accumulation from eroding the installation surface.
