schroefveren

Schroefveer is a Dutch term used for springs that interact with screw threads or are adjusted via screws. The precise meaning depends on context, but the common idea is a spring element whose preload, length, or position is controlled by rotation or threaded engagement with a housing or fastener. In many sources, schroefveren are described as either conventional coil springs used in threaded assemblies or as springs that include a threaded portion for direct adjustment.

Construction and types: They are typically made from spring steel, stainless steel, or bronze. They can be standard coil springs placed in a threaded housing, or coil springs with a machined or rolled threaded segment that mates with a screw. They may be cylindrical, conical, or have variable pitch to tailor force-deflection characteristics.

Manufacturing: Production involves drawing or twisting wire to the desired diameter, forming into a helical shape, and heat-treating to achieve required hardness. If a threaded portion is required, threading is done by machining or rolling, either before or after heat treatment, to preserve surface quality.

Applications: Schroefveren are used in precision mechanisms requiring adjustable preload or position, such as micrometer stages, camera mechanisms, clamping devices, and certain automotive components. They offer compactness and a straightforward means of adjustment.

Note: Because the term is used in different industries, exact specifications are best confirmed from the relevant technical documentation.
