example 1

[0075] Example 1: Such as Figure 1 to Figure 38 As shown, a gearbox is disclosed. The gearbox includes a box, a shaft, and a gear. A shaft is installed in the box and a gear is provided on the shaft. The feature is that the gear adopts a multi-layered gear; The gear includes a gear body 5. The gear body 5 is formed by superimposing a plurality of quenched toothed thin parts 1 on each other. The thin part 1 has at least one connecting hole 2 and a connecting hole after the multiple thin parts 1 are superimposed. 2 overlapped to form a through hole, the connecting holes 2 are fixedly connected to the gear body 5 with a connecting piece, and then the gear body 5 is immersed in the metal solution. The gear body 5 is taken out from the metal solution and cooled, the metal solution solidifies into metal and is filled in Between the thin parts 1 of the gear body 5 and the surface of the gear body 5, the following processing steps are adopted:

[0076] Step 1): The sheet metal is machin...

example 2

[0086] Example 2: Such as Figure 1 to Figure 4 As shown, the method of Example 1 is used to process the rack, and the following processing steps are used:

[0087] Step 1): 2mm thickness 45# steel plate is processed into thin rack-shaped parts 1-1 and thin-shaped rack parts 1-1 by one of the methods of stamping, wire cutting, laser cutting, plasma cutting, and high-pressure liquid cutting. There are two connecting holes 2;

[0088] Step 2): Perform quenching treatment on the formed sheet rack-shaped part 1-1 in the high frequency coil of the electronic high frequency furnace, and the quenching adopts any of high frequency quenching, intermediate frequency quenching or heat quenching in a heat treatment furnace;

[0089] Step 3): Then 15 pieces of thin-sheet rack-shaped parts 1-1 are put into the rack-shaped mold for superimposing and splicing to form a rack shape, and the connecting holes 2 of the 15 pieces of thin-film parts 1 are superimposed into a through hole;

[0090] Step 4): ...

example 3

[0097] Example 3: Such as Figure 1 to Figure 2 as well as Figure 5 to Figure 7 As shown, the method of example 1 or 2 is used to process long racks. When producing long racks, the specific arrangement method of the thin-shaped rack-shaped parts 1-1 is: firstly, use more than one thin tooth on the rack-shaped mold. The strip parts 1-1 are connected to form a long rack-shaped sheet part, and then the multi-layer connected to form a long rack-shaped sheet part is superimposed, the spliced ​​long rack-shaped sheet part on the previous piece and the next spliced ​​long rack Shaped sheet parts are spliced ​​in a staggered stacking manner, and the long rack-shaped sheet parts spliced ​​in multiple layers form a long rack shape, and the connecting holes of multiple long rack-shaped sheet parts are superimposed into through holes; The gear is mounted on a shaft in the box of the gearbox and assembled into a gearbox.

Abstract

The invention relates to a gear speed changing box, in particular to a speed changing box of a gear. The gear is formed by laminating a plurality of quenched sheet parts with teeth, and gaps of the gear are filled with a metal solution. The speed changing box comprises a box body, a shaft and the gear, the shaft is installed in the box body, and the gear is arranged on the shaft. The gear speed changing box is characterized in that the gear is a multilayer gear; the gear comprises a gear body, and the gear body is formed by laminating the multiple quenched sheet parts with the teeth; at least one connecting hole is formed in each sheet part, the connecting holes are laminated to form a through hole after the sheet parts are laminated, and the connecting holes are fixedly connected into the gear body through connecting pieces; and then the gear body is soaked into a metal solution, the gear body is taken out from the metal solution to be cooled, the metal solution solidifies into metal to be injected into the positions between the sheet parts of the gear body and the surface of the gear body, and the technical aim of rapidly manufacturing the gear with the high physical property in a low-cost manner is achieved.

Description

Technical field [0001] The present invention relates to a gear box, in particular to a gear box that adopts a gear that is formed by superimposing a plurality of quenched toothed sheet parts and is filled with a metal solution. Background technique [0002] Gearboxes are widely used in the mechanical field. Gearboxes usually change the speed of the driving shaft and the driven shaft through the transmission of gears with different numbers of teeth. In the production process of the gearbox, the production of one gear is a technical problem. [0003] Gear refers to a mechanical element with teeth on the rim that can continuously mesh and transmit motion and power. The first gear transmission in China has been used since the Three Kingdoms period. There have been records of gear transmission in foreign countries in 300 BC. Therefore, gear transmission is in The mechanical field has been widely used since ancient times. [0004] Common gears can be divided into gears with circular cross...
