A gear is a rotating circular machine part having incising or, in the case of a cog or bull gear, inserting teeth (called a cog) which meshes with another (compatible) toothed part to transmit (convert) torque and speed. The fundamentals behind how gears work are similar to the fundamentals of a lev

GMM Universal Gear Detector is a new type of intelligent gear measuring instrument. It adopts the measurement principle of electronic generation, does not require base disc and reference detection components, and has high detection accuracy. It can detect involute cylindrical spur teeth, helical teeth, and it can complete the measurement of the tooth shape, tooth direction and pitch error of the involute gear under the condition of one clamping.
