hammaspyörämittauslaitteina

Hammaspyörämittauslaitteet, or gear measuring machines, are specialized instruments used to accurately determine the dimensions and profiles of gears. These devices are crucial in the manufacturing and quality control processes of gears, ensuring they meet precise specifications for optimal performance and longevity in various applications, such as automotive powertrains, industrial machinery, and aerospace systems.

The primary function of a gear measuring machine is to assess critical gear parameters. This includes measuring tooth dimensions like the addendum, dedendum, and tooth thickness. Furthermore, it verifies the tooth profile, ensuring it conforms to the designed involute or other specified curves. Lead and helix angles, essential for smooth meshing and load distribution, are also accurately measured. Runout, which refers to the deviation of the gear's axis of rotation from its geometric axis, is another key parameter evaluated.

Modern gear measuring machines often employ advanced technologies, including coordinate measuring machines (CMMs) equipped with specialized probes or non-contact optical scanning systems. These technologies allow for high-precision measurements of complex gear geometries. Data obtained from these machines is typically analyzed using sophisticated software that compares the measured values against digital models or standards, highlighting any deviations and providing detailed reports for quality assurance. The accuracy and reliability of these measurements are vital for preventing premature wear, noise, and vibration in geared systems.
