Embodiment 1

[0032] Example 1 discloses a processing technology of face teeth, such as figure 1 As shown, including the following steps:

[0033] Step 101: Prepare materials, prepare the materials for processing the face teeth;

[0034] Step 102: Forging, forging the material to obtain forged parts;

[0035] Step 103: Heat treatment, heat the forged part in a heating furnace to 770, cool by spraying water after holding for 30 minutes, and obtain a heat-treated part. The hardness of the heat-treated part after heat treatment is 20HRC. The forging produced in step 2 is removed by heat treatment. At the same time, the hardness of the heat-treated parts is reduced, and the plasticity is improved, which is convenient for subsequent turning and processing;

[0036] Step 104: Turning one, place the heat-treated part in the turning center, and turn the outer circle, end face, web surface and inner hole of the heat-treated part to obtain the first turned part;

[0037] Step 105: Rough machining of the teeth...

Embodiment 2

[0049] Embodiment 2 discloses a processing technology of face teeth, including the following steps:

[0050] Step 101: Prepare materials, prepare the materials for processing the face teeth;

[0051] Step 102: Forging, forging the material to obtain forged parts;

[0052] Step 103: Heat treatment, heat the forged part in a heating furnace to 800°C, spray water for cooling after holding for 35 minutes, and obtain a heat-treated part. The hardness of the heat-treated part after heat treatment is 22HRC, and the heat-treated part is removed by heat treatment. Forging stress, at the same time, the hardness of the heat-treated parts is reduced, and the plasticity is improved, which is convenient for subsequent turning and processing;

[0053] Step 104: Turning one, place the heat-treated part in the turning center, and turn the outer circle, end face, web surface and inner hole of the heat-treated part to obtain the first turned part;

[0054] Step 105: Rough machining of the teeth, position...

Abstract

The invention discloses a processing technique of end teeth, comprising the steps of 1, preparing a material; 2, forging; 3, carrying out thermal treatment; 4, carrying out turning I; 5, roughly machining teeth; 6, drilling, and machining screw holes; 7, carrying out high-frequency thermal treatment; 8, carrying out carburization thermal treatment; 9, carrying out turning II; 10, grinding; 11, flattening by dressing, and polishing; 12, inspecting, and measuring; 13, cleaning; 14, oiling, and packaging. Modifications are made herein in order to solve the problems that, for instance, end teeth processed by means of existing end tooth processing techniques are low in hardness, poor in wear resistance, prone to rusting, low in surface flatness, prone to causing noise during operating and shortin service life. The processing technique herein has the advantages that, for instance, end tooth hardness is improved, end tooth wear resistance is improved, corrosion resistance of end teeth is improved, surface flatness of end teeth is improved, the end teeth produce less noise during operating, and the end teeth have longer lives.

Description

Technical field [0001] The present invention relates to the field of machinery, in particular to a processing technology of face teeth. Background technique [0002] The drive shaft is a high-speed, low-supported rotating body. In mechanical operation, the drive shaft plays a vital role. One way of transmitting power of the drive shaft is to transmit through the face teeth, which can continuously mesh and transmit power. , The requirements for wear resistance, surface hardness, and fatigue resistance of face teeth are very high. The power transmission effect of the drive shaft largely depends on the quality of the face teeth, and the quality of the face teeth depends on the processing of the face teeth Process, the heat treatment process in the traditional face tooth processing technology is relatively simple, the hardness of the face tooth often does not meet the requirements, and the wear resistance is poor. The face tooth will be physically deformed after heat treatment. The t...
