Gear shaft odd-tooth addendum circle detector and use method thereof

Abstract

The invention discloses a gear shaft odd-tooth addendum circle detector and a use method thereof. A checking mechanism comprises a checking base and a checking sleeve which is connected with the checking base. The checking mechanism comprises the checking base and the columnar checking sleeve which is connected with the checking base. The checking sleeve is provided with a horizontal balancing block. The checking base is provided with checking rods. A detection mechanism comprises a supporting base which is detachably connected on the balancing block. The supporting base is provided with even number of checking supporting rods which are abutted against the external circumferential surface of the checking sleeve. End surface positioning blocks are arranged between the tangent end surfaces of the supporting base and gear shafts. A gauge rod is connected on the supporting base. A dial indicator is installed on the gauge rod. The left and right end surface positioning blocks close to the end surfaces of the gear shafts are abutted against the neck end surfaces of the gear shafts. The steel balls on the checking supporting rods and the necks of the gear shafts are tangent and are equal in height. The gear shaft odd-tooth addendum circle detector and the use method thereof aim at solving the problems that accuracy is poor and the measurement process is complex due to the fact that K value conversion or three-coordinate measurement is adopted in existing gear shaft addendum circle diameter.

Description

technical field [0001] The invention relates to the field of metering equipment characterized by mechanical methods, in particular to a gear shaft odd addendum circle detector and a use method. Background technique [0002] In the machining process of the gear shaft, the diameter of the addendum circle is an important parameter in the detection process. When actually measuring odd-numbered addendum circles, it is necessary to convert the value of the addendum circle diameter correction coefficient K, because during measurement, the size directly measured by the measuring tool is not the addendum circle diameter da, but the tip of one tooth to the opposite tooth The distance H between the addendum circle chords (see attached Figure 11 , Figure 12 shown), but when the gear modulus is larger and the number of teeth is smaller, the actual measurement error of the measurement will be larger, which will affect the accuracy of the actual size; The process is cumbersome, and it ...
