Description

Technical Field

[0001] The utility model relates to the technical field of circular arc gear detection, and in particular to a positioning structure for circular arc gear clearance detection. Background Art

[0002] Arc gear transmission is a point meshing gear transmission with an arc-shaped tooth profile. There are usually two forms of meshing: the pinion has a convex arc tooth profile and the gear has a concave arc tooth profile, which is called a single arc gear transmission. Arc gears refer to point meshing gears with an arc-shaped tooth profile. Arc gear transmission usually has two forms of meshing: the pinion has a convex arc tooth profile and the gear has a concave arc tooth profile, which is called a single arc gear transmission. The large and small gears are made into convex arc tooth profiles outside their respective pitch circles, and the parts inside the pitch circles are made into concave arc tooth profiles, which is called a double arc gear transmission.

[0003] The clearance requirements for multiple sets of gears that mesh with each other and rotate are different, so it is necessary to test and detect the clearance of multiple sets of gears. However, the shape of the arc gear is not convenient for direct measurement, so it is necessary to measure it indirectly, which means positioning the arc gear and then measuring the gear clearance. For this reason, we propose a positioning structure for arc gear clearance detection. Utility Model Content
