Embodiment Construction

[0054] like figure 1 , 2 , 3, the bevel gear tooth thickness measuring instrument is mainly composed of a sine gauge 1 (with a mandrel 2), a right-angle curved ruler with a micrometer sleeve and a reading device 5, a height gauge 6, a gauge block 10, a steel ball 4, and a micrometer 5 (the ruler frame, measuring anvil and locking device have been removed).

[0055] The worktable of the bevel gear tooth thickness measuring instrument is roughly rectangular, and the sine gauge 1 and the right-angle bending ruler are respectively installed at both ends of the workbench, and the installation angles of the sine gauge 1 and the right-angle bending ruler are parallel to each other; The right-angle curved ruler and the workbench are moved through the clearance fit of the guide groove and the guide key, and are positioned by the knurled bolt 8 and the T-nut 9; the upright part of the right-angle curved ruler is a height gauge 6, and the height gauge 6 An adjustment sleeve 7 is instal...

Abstract

The invention provides a bevel gear tooth thickness measurer, which comprises an operation table, a sine gauge, a mandrel, a right-angled curved ruler, a height gauge, a gauge block and a micrometer. The bevel gear tooth thickness measurer is characterized in that the sine gauge and the right-angled curved ruler are mounted at two ends of the operation table respectively, mounting angles of the sine gauge and the right-angled curved ruler are mutually parallel, the height gauge and an adjusting sleeve are arranged on the right-angled curved ruler and movably connected with the operation table, the micrometer with a holder, an anvil and a locking device removed is mounted on the adjusting sleeve, the micrometer is parallel to a basal plane of the operation table, an axillary steel ball is placed in the middle of a tooth space of the bevel gear to be measured and slightly close to a small end, and positioned in the middle of a contact area, and then relevant dimensional data are measured. The tooth thickness of a portion, where the steel is positioned, of the bevel gear is obtained by calculating, and the tooth thickness of a large end of the measured bevel gear is obtained. The bevel gear tooth thickness measurer can be used for measuring the thickness of optional-section teeth, especially in the middle of the contact area, and no back cone needs to be used as a measurement datum.

Description

technical field [0001] The invention belongs to the field of machinery and relates to gear measurement technology, in particular to a bevel gear tooth thickness measuring instrument. Background technique [0002] The measurement of bevel gear tooth thickness has long relied on traditional methods such as gear vernier calipers, optical tooth thickness calipers, tool microscopes or ball measuring heads with back cones as references, but the measurement of bevel gear tooth thickness must rely on the measurement reference, namely the theoretical outer diameter and crown distance . In the prior art, a gear vernier caliper is usually used to measure the tooth thickness of bevel gears. Because it is impossible for general bevel gears to obtain the actual outer diameter and actual crown distance after processing, which are completely consistent with the theoretical outer diameter and theoretical crown distance data without deviation. The gear is precisely based on the sharp point o...
