Embodiment Construction
[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0013] Such as figure 1 As shown, the tooth thickness micrometer of the present invention has been improved and designed on the basis of the common normal line micrometer. In order to accurately measure the tooth height of the gear teeth, a micrometer vertical differential measuring rod 1 is vertically installed in the middle of the original micrometer body 3, and the measuring end of the differential measuring rod is polished into a round flat measuring head similar to a common normal line micrometer.
[0014] Such as Figure 4 As shown, when measuring, first align the vertical differential measuring rod 1 to the zero position, then rotate the differential cylinder of the vertical differential measuring rod 1, adjust it to the size required by the corresponding tooth height of the gear teeth 5 and lock the differential cylinder; finally, turn the diff...

The invention relates to a micrometer and in particular to a tooth thickness micrometer. The tooth thickness micrometer is mainly used for gear processing detection and accuracy measurement. A vertical differential measuring rod is vertically arranged in the middle of a micrometer body of a common normal line micrometer, a measuring head of a measuring end of the differential measuring rod is a round flat measuring head. A method measuring gear tooth thickness comprises: firstly, adjusting zero position of the vertical differential measuring rod; then rotating a microdrum of the vertical differential measuring rod, adjusting to sizes required by corresponding gear heights and locking the microdrum; at last, a measuring face of the measuring head of the vertical differential measuring rod is fitted and contacted with a gear top face of a gear to be measuring, and adjusting measuring faces of two horizontal measuring heads of the micrometer to be contacted with a gear face of gear teeth; and reading indication on a horizontal differential measuring rod, and the indication is a tooth thickness value of the gear teeth to be measured. The tooth thickness micrometer has the advantages that the accuracy degree of the measured gear tooth thickness is 0.01, can meet accuracy measuring requirements of gear tooth thickness with high accuracy, and is convenient to operate.
Description
Technical field: [0001] The invention relates to a micrometer, in particular to a tooth thickness micrometer and a method for measuring the tooth thickness of gear teeth, which are mainly used for gear processing detection and precision measurement. Background technique: [0002] The machining accuracy of gear tooth thickness is very important, especially the precision measurement of gear tooth thickness will directly affect the technical performance of the gear pair after assembly. At present, tooth thickness vernier calipers are generally used to measure the thickness of gear teeth in the production workshop and processing site. This measurement method does not have high requirements for the machining accuracy of gear tooth thickness, and can basically meet the requirements; for the processing of gears with higher precision, the existing detection methods cannot meet the requirements. Invention content: [0003] Aiming at the shortcomings of the above measuring tools, t...
