Kannatuslevy

Kannatuslevy is a flat plate used in mechanical engineering and construction to distribute a load from a component onto a larger, supporting surface. It serves as a base or interface for mounting machinery, structural frames, or equipment, helping to spread bearing pressure and improve alignment and stability.

Functions and characteristics

A kannatuslevy provides a stable, flat contact area for bolts, studs, or welds and can accommodate various mounting patterns. By distributing load over a larger area, it reduces local bearing stress and helps prevent surface damage or deformation of both the mounted part and the substrate. The plate may include holes, slots, or other features for fasteners, and its tolerances, flatness, and edge quality are chosen to suit the mounting requirements.

Materials and finishes

Kannatuslevy is typically made from steel (carbon steel or stainless steel) and can also be crafted from aluminum or composite materials for lighter applications. Surface finishes range from bare metal to galvanizing, plating, or painting, selected for corrosion resistance, wear, and environmental conditions.

Design considerations

Key considerations include load capacity, bolt pattern and hole quality, edge distance, flatness, and alignment needs. The thickness and material are selected based on the assessed load, vibration, and temperature, while surface protection is chosen to resist corrosion and wear in the operating environment.

Applications

Common uses include bases for motors and gearboxes, supports in steel structures, mounting points for pumps and conveyors, and as interfaces between disparate components to ensure even load transfer and easy reconfiguration.
