Description

Technical Field

[0001] The utility model relates to the technical field of gear measurement, in particular to a gear span measuring device. Background Art

[0002] In gear transmission, the side clearance of the gear pair must be guaranteed. The side clearance is controlled by the center distance of a pair of gears during operation and the actual tooth thickness of each gear. Therefore, the tooth thickness of the gear must be controlled during the production and processing.

[0003] Gear tooth thickness can be controlled by measuring the span distance and other methods. The span distance is generally measured by the measuring rod method. During measurement, the measuring rods are placed in the corresponding tooth grooves, and then the distance between the two measuring rods is measured with an outside micrometer. When measuring with a micrometer, the measuring ruler will rub against the outer wall of the gear, causing the gear to shake, and then it is easy to deviate from the original position, resulting in deviations in the measured data. In addition, the process of replacing the gear is relatively cumbersome. Therefore, a gear span distance measuring device is proposed. Utility Model Content
