TLDR
In this paper, a small-modulus small-tooth-number spiral bevel gear powder metallurgy process is described, where the shape of a relevant contact area and transmission noise are tested under a meshing simulation state.Abstract:
The invention discloses a small-modulus small-tooth-number spiral bevel gear powder metallurgy process. The process comprises the following steps that the structure of a spiral bevel gear is determined by adopting a three-dimensional digital-to-analogue mode, and the shape of a relevant contact area and transmission noise are tested under a meshing simulation state; proportional power is pressed and formed after a spiral angle and a pressure angle of the spiral bevel gear are modified; and a pressed and formed part is put in a closed furnace for sintering, an inner hole and the end surface aremachined, and finishing treatment is conducted on the part. According to the process, the advanced powder metallurgy process is adopted, so that the small-modulus small-tooth-number powder metallurgyspiral bevel gears with complex structures can be produced in an industrialization large-scale manner, the surfaces are smooth, the noise during meshing is small, the density of product tooth parts is uniform, the manufacturing cost is low, and the large-scale production and use requirements can be met.read more
