lisälevyt

Lisälevyt are flat plates added to an existing component or assembly to modify geometry, distribute loads, or provide a mounting interface. They function as reinforcement, spacers, adapters, or contact surfaces and are used across multiple industries where additional bearing area or alignment is needed.

Materials and forms vary widely. Common materials include steel (carbon or stainless), aluminum, brass, and durable plastics. Thicknesses range from fractions of a millimeter for lightweight applications to several millimeters for structural use. Lisälevyt can be solid or perforated, and they may include features such as countersunk holes, counterbores, or slots to align with fasteners and existing hole patterns.

Applications span mechanical engineering, construction, automotive, electronics enclosures, and furniture assembly. They are used to reinforce joints, extend mounting widths, distribute stresses around connections, compensate for misalignment, or provide standardized mounting surfaces when replacing components. In automotive and machinery contexts, lisälevyt often function as spacers or adapters to achieve correct wheel alignment, shaft positioning, or gearbox mounting.

Design and installation considerations include selecting a compatible material and corrosion resistance for the environment, ensuring adequate edge distance and hole spacing, and choosing appropriate fastening methods and torques. Edges are typically deburred to prevent injury or damage, and in structural applications plates may be welded or bolted depending on the required strength. In assemblies with dissimilar metals, coatings or isolating barriers can prevent galvanic corrosion.
