example 1
[0074] Example 1: if Figure 1 to Figure 38 As shown, a gear box is disclosed, and the box includes a box, a shaft, and a gear. A shaft is installed in the box, and there are gears on the shaft. It is characterized in that: the gear adopts a laminated gear; The gear includes a gear body 5, and the gear body 5 is formed by superimposing a plurality of toothed sheet parts 1. There is at least one connection hole 2 on the sheet part 1, and the connection holes 2 after the superposition of the plurality of sheet parts 1 overlap to form a The through holes and the connecting holes 2 are fixedly connected by connecting pieces to form a gear body 5. The gear body 5 is quenched and heated and then immersed in the metal solution. The gear body 5 is taken out of the metal solution and subjected to a quenching and cooling process. The metal solution is cooled and solidified into metal and filled. between the thin parts 1 of the gear body 5 and the surface of the gear body 5, and adopt th...
example 2
[0085] Example 2: if Figure 1 to Figure 4 As shown, the rack is processed by the method of Example 1, and the following processing steps are adopted:
[0086] Step 1): The 45# steel plate with a thickness of 0.2mm is processed into a sheet rack-shaped part 1-1 by one of methods of stamping, wire cutting, laser cutting, plasma cutting, and high-pressure liquid force cutting, and a sheet rack-shaped part 1- There are two connecting holes 2 on 1;
[0087] Step 2): Then 8 thin slice rack-shaped parts 1-1 enter the rack-shaped mold 3 for superposition and splicing to form a rack shape. through hole;
[0088] Step 3): Then insert connecting parts such as rivets or bolts between the connecting holes of the above-mentioned shaped racks for fixed connection, forming a short rack 5-1;
[0089] Step 4): The semi-finished product inspection is carried out to described short rack 5-1, the qualified short rack 5-1 that reaches drawing outline design requirement enters next step, unquali...
example 3
[0096] Example 3: if Figure 1 to Figure 4 As shown, the rack is processed by the method of Example 2, and the following processing steps are adopted:
[0097]Step 7) Completed in the vacuum box, the metal solution immersed in the short rack 5-1 is selected from any one of the following or a mixture of two or more in any proportion: lead liquid, tin liquid, copper liquid, copper liquid, aluminum liquid ;
[0098] During the process of immersing the gear body in the metal solution in the vacuum box, turn off the vacuum pump and quickly open the intake valve to allow the air to enter the vacuum box quickly. When the pressure in the vacuum box is balanced with the normal pressure, close the intake valve and turn on the vacuum pump again pressure suction;
[0099] All the other steps are identical with example 2;
[0100] The manufactured gears are installed on the shafts in the casing of the gearbox to assemble the gearbox.
