How to check the mesh marks of the main and driven bevel gears in the final reducer?

  The driving bevel gear should not only have a suitable meshing clearance, but also have a suitable meshing trace, that is, the stress area is large and the stress position is correct. For the driving bevel gear, several gear teeth can be engaged in meshing at the same time, so a large stress area can be obtained, but the transmission process must gradually move from the small end to the large end, and it needs to be adjusted to make it have correct meshing traces . Therefore, evenly coat a thin layer of red powder on the surface of the adjacent three or four teeth of the driving bevel gear. Rotate the flange on the driving bevel gear shaft. The correct meshing mark should tend to the middle of the tooth side, close to the small end of the front face of the driven bevel gear (that is, the meshing surface of the driven bevel gear and the driving bevel gear when the car is moving forward). The meshing marks should be located in the length direction from the small end 2. The length of 0-4.0mm accounts for 60% of the tooth length; the meshing marks should be located in the height direction from the tooth top 0. The height of 8-1.6mm accounts for 50% of the tooth height. The mesh marks on the reverse side of the driven bevel gear are similar to those on the front side.
