Figure 1 shows the engineering drawing of spiral bevel gear bearing structure female die. The outer diameter of the die bearing is 225mm, the inner diameter of the die bearing is 182.6mm and its height is 54mm. The three-dimensional geometric modeling of spiral bevel gear bearing structure concave die is shown in Figure 2, which is composed of three parts: bearing outer ring, inner ring concave die and cylindrical roller.
Figure 3 shows the engineering drawing of the tooth cavity of spiral bevel gear. The outer diameter of the tooth cavity is 132mm, the inner diameter is 87mm, the height of the tooth cavity is 54mm and the height of the groove is 27mm. The three-dimensional geometric modeling of spiral bevel gear tooth cavity is shown in Figure 4.
Figure 5 shows the engineering drawing of cylindrical roller in the centripetal bearing die structure of spiral bevel gear. The diameter of cylindrical roller is 33.8mm and the height is 27mm. The three-dimensional geometric modeling of cylindrical roller is shown in Figure 6.
