mõõterõngas

Mõõterõngas is an Estonian term that translates to "measuring ring" or "caliper ring" in English. It refers to a specific type of measuring tool used for determining the diameter of an object. These rings are typically circular or oval and are manufactured to precise internal dimensions.

The primary function of a mõõterõngas is to check if an object falls within a specified size range. An object is considered to be within tolerance if it can pass through the ring, or if it fits snugly within the ring without excessive play. Conversely, if the object cannot pass through the ring, it is too large, and if it passes through too easily, it is too small.

Mõõterõngas tools are often used in manufacturing and quality control processes to ensure that components meet dimensional specifications. They are particularly useful for measuring external diameters of shafts, pipes, rods, and other cylindrical or circular parts. Their simplicity and ease of use make them an efficient method for rapid dimensional inspection.

These rings can be made from various materials, including hardened steel, to ensure durability and maintain accuracy over time. They can be manufactured as go/no-go gauges, meaning one ring might be sized for the minimum acceptable diameter (a "go" gauge) and another for the maximum acceptable diameter (a "no-go" gauge). This allows for quick verification of whether a part meets the required dimensional criteria.
