example 1
[0074] Example 1: if Figure 1 to Figure 38 As shown, a cemented gear gearbox is disclosed. The gearbox 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 multi-layer dipped gear; The gear includes a gear body 5, and the gear body 5 is formed by superimposing a plurality of quenched toothed sheet parts 1. The thin sheet parts 1 have at least one connecting hole 2. After the multi-sheet sheet parts 1 are stacked, The connecting holes 2 are overlapped to form through holes, and the connecting holes 2 are fixedly connected to form a gear body 5 by connecting pieces, and then the gear body 5 is immersed in glue, and after the gear body 5 is taken out from the glue, the glue solidifies and fills each part of the gear body 5. Between the sheet parts 1 and the surface of the gear body, the processing steps of the gear are as follows:
[0075] Step 1): the sheet metal is machined into ...
example 2
[0082] Example 2: if Figure 1 to Figure 4 As shown, the rack is processed by the method of Example 1, and the sheet rack-shaped parts 1-1 are superimposed and spliced into a short rack 5-1, and a rack-shaped gear body 5, the surface of the gear 5 and each sheet part There is metal powder between 1, after the gear body 5 is taken out from the glue, the glue and metal powder are solidified and filled between the thin parts 1 of the gear body 5 and the surface of the gear body 5, the specific steps are:
[0083] Step 1): The 45# steel plate with a thickness of 2mm is processed into a sheet rack-shaped part 1-1 by one of the methods of stamping, wire cutting, laser cutting, plasma cutting, and high-pressure liquid force cutting, and a sheet rack-shaped part 1-1 There are two connecting holes 2;
[0084] Step 2): Carry out quenching treatment to the thin slice rack-shaped parts 1-1 after forming, and quenching adopts any one of processes such as high-frequency quenching, interm...
example 3
[0091] Example 3: if 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 thin slice rack-shaped parts 1-1 is: first, on the rack-shaped mold, more than one thin slice tooth The bar-shaped parts 1-1 are connected to form a long rack-shaped sheet part, and then the multi-layer connection to form a long rack-shaped sheet part is superimposed. Shaped sheet parts are spliced in the way of dislocation and superposition, and the long rack-shaped sheet parts are spliced in multiple layers to form a long rack shape, and the connection holes after the superposition of multiple long rack-shaped sheet parts are overlapped to form through holes; The gears are installed on the shafts in the case of the gearbox, and the gearbox is assembled.
