Device for measuring of root circle by using knives internal tooth systems with odd numbers of teeth

摘要

Measuring device for measuring root circle by knives internal tooth systems with odd numbers of teeth, in particular for determining the desired dimension, on the direct measuring path, by means of a hand tool, for example, an internally measuring screw, characterized in that it is a measuring bridge (1) with at least two the of a tooth gap (10) opposite tooth (11), which bridges over measuring sensors (2) provided between measuring bridge (1) and a tooth gap (10) a the distance (d) between the measuring bridges upper part (6) and the tooth gap (10) on the inside, which determines the measuring screw (5) can be inserted.
