example 1

[0072] Example 1: if Figure 1 to Figure 38 As shown, a processing method of a laminated gear is disclosed. The gear includes a gear body 5, and the gear body 5 is formed by stacking a plurality of toothed sheet parts 1, and the sheet parts 1 have at least one Connecting hole 2, the connecting hole 2 after stacking of multi-piece sheet parts 1 overlaps to form a through hole, and the connecting holes 2 are fixedly connected with a connecting piece to form a gear body 5, and the gear body 5 is quenched and heated and immersed in a metal solution, and the gear body 5 Take out from the solution, carry out the 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, which is characterized in that the processing steps are as follows:

[0073] Step 1): the sheet metal is machined into a toothed sheet part 1; the sheet part 1 has at least one connecting hole 2;

example 2

[0082] Example 2: if Figure 1 to Figure 4 As shown, adopt the method of Example 1 to process the rack, the steps are:

[0083] 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 the 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;

[0084] 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;

[0085] 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;

[0086] 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, unqualified short rack 5-1 enters ...

example 3

[0092] Example 3: if Figure 1 to Figure 4 As shown, adopt the method of example 2 to process the rack, the steps are:

[0093] 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 ;

[0094] 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;

[0095] All the other steps are the same as Example 2.

Abstract

The invention relates to a machining method of a laminated gear. The objective of the invention is to solve technical problems such as complicated techniques, long processing time, high machining difficulty and high machining cost in gear machining in the prior art. The gear includes a gear body; a plurality of thin sheet components with teeth are stacked to each other so as to form the gear body; at least one connecting hole is formed in each thin sheet component; after the plurality of thin sheet components with teeth are stacked to each other, the connecting holes are overlapped with each other so as to form a through hole; the connecting holes are fixedly connected with each other through connecting components, so that the gear body can be formed; the gear body is quenched and heated, and then is immersed into a metallic solution; the gear body is taken out from the metallic solution so as to be subjected to quenching and cooling processing; the metallic solution is cooled and is solidified, and forms metal, and fills gaps between the thin sheet components of the gear body and the surface of the gear body. According to the machining method, when quenching is performed on the gear body which is formed through stacking the plurality of thin sheet components with teeth, the metallic solution fills the gaps. With the machining method adopted, a high-physical performance gear can be manufactured fast with low cost.

Description

technical field [0001] The invention relates to a gear processing method, in particular to a gear processing method which is formed by superimposing a plurality of toothed sheet parts and filling gaps with metal solution during quenching. Background technique [0002] Gears refer to the mechanical elements with teeth on the rim that can continuously mesh to transmit motion and power. The initial gear transmission in China has been used since the Three Kingdoms period, and there have been records of gear transmission in foreign countries in 300 BC. Therefore, gear transmission in It has been widely used in the field of machinery since ancient times. [0003] Common gears can be divided into gears with circular cross-section, racks and special-shaped gears with non-circular cross-section from the appearance. [0004] Commonly used gear processing methods are generally divided into profiling processing method and fan forming method, such as: hobbing machine gear processing, mi...
