Example Embodiment
[0075] Method embodiment one:
[0076] See figure 1 The figure is a flow chart of the method for measuring the pitting area ratio of the tooth surface provided by an embodiment of the application.
[0077] Such as figure 1 As shown, the method for measuring tooth surface pitting area rate provided by this embodiment includes:
[0078] S101: Obtain a collection image of the tooth surface of the gear.
[0079] First, we need to understand the correlation between gear tooth surface, meshing area, pitting pits and pitting area ratio.
[0080] The gear contains a plurality of teeth, and each tooth contains two tooth surfaces for meshing with the teeth of other gears, namely the front surface and the back surface of the tooth surface. There is a meshing area on each tooth surface of each tooth, and pitting pits are formed on the meshing area due to long-term wear. Pitting pits are mainly distributed in the meshing area of the tooth surface. Pitting area ratio refers to the area occupancy...
Example Embodiment
[0156] Method embodiment two:
[0157] See Figure 5 The figure is a flow chart of the method for measuring the pitting area ratio of the tooth surface provided by this embodiment.
[0158] Such as Figure 5 As shown, the method for measuring the pitting area rate on the front surface of the tooth surface provided by the embodiment of the present application includes:
[0159] S501: At a preset time interval t 1 Take a picture of the front surface of the gear tooth surface, and acquire an image of the front surface of the gear tooth surface.
[0160] In this embodiment, t 1 = 0.5 seconds. Note down the collection time t of the front image of a certain tooth surface.
[0161] S502: Use the region-of-interest segmentation method to process the acquired images of the tooth surface, and determine the acquired images of the tooth surface that meet the requirements.
[0162] In this embodiment, the threshold T g Perform threshold segmentation on the image collected from the front of the tooth...
