Description

Technical Field

[0001] The present invention relates to the field of planetary gear detection, and in particular to a planetary gear detection device and a detection method thereof. Background Art

[0002] Planetary gears refer to gear systems that can rotate around their own axes of rotation like fixed-axis gears, and their axes of rotation can also rotate around the axes of other gears along with the planet carrier. Rotation around one's own axis is called "autorotation", and rotation around the axes of other gears is called "revolution", just like the planets in the solar system, hence the name. When producing planetary gears, it is necessary to inspect each gear plate to check whether there are defects or missing teeth on the surface, as well as the spacing between the teeth, to determine whether the gear plate of the planetary gear is qualified. Most of the current inspection methods use visual inspection or standard gears for meshing inspection. However, during inspection, only one item can be inspected each time, such as appearance, size or teeth, which is not convenient for batch and rapid inspection. In addition, when inspecting, the number of teeth and the spacing between teeth of different types of gear plates are not the same, which has the problem of poor applicability and is not convenient for use.

When the movable block 43 is used for gear plates of different specifications, the applicability is improved, and the displacement of the movable block 43 is controlled by the electric telescopic rod 42, so that the movable block 43 and the adjusting block 45 are moved in the direction of the teeth to detect the position of the teeth, and when the movable block 43 is retracted, the rotation of the gear plate is avoided to be affected, and each gear tooth is detected one by one to improve the detection accuracy.

When a defect occurs on the surface of the gear plate, the extension of the spring 56 releases the pressure on the auxiliary press-type sensor 54, and then it is determined that there is a depression on the surface of the gear plate, which facilitates the detection of the surface.
