Abstract

The utility model relates to a measuring instrument for an internal gear with a circular-arc tooth profile. According to the background technology in the prior art, existing gear measuring instruments are mostly designed for measuring external gears and measuring instruments especially used for measuring internal gears are not common. The measuring instrument for an internal gear with a circular-arc tooth profile comprises a measuring ball (1), a micrometric screw (2), a fixed sleeve (3) and a micrometer tube (4). The measuring ball (1) is clamped at the top of the micrometric screw (2). The micrometric screw (2) is of a symmetrical structure and is connected with the two ends of the micrometer tube (4). The micrometric screw (2) is also connected with the fixed sleeve (3). The outside of the micrometric screw (2) is provided with external threads and the interior of the fixed sleeve (3) is provided with internal threads. The fixed sleeve (3) and the micrometer tube (4) are provided with scales. According to the technical scheme of the utility model, the above measuring instrument can be used for measuring the pitch of circular-arc teeth and the inner diameter of the gear and is accurate in measurement and simple and practical in structure.
