Embodiment 1

[0047] Such as figure 1 As shown, a method for processing the composite lubrication structure of sliding bearings based on electron beam solidification, the steps are as follows:

[0048] (1) Selection of solid filling materials: Titanium diboride with a particle size of 1 μm and a Mohs hardness of 2 and zinc borate with a particle size of 2 μm and a Mohs hardness of 2 are used as solid lubricating materials, and the ratio of the two is 2: 3; Take bisphenol A epoxy resin Epon828 as the curing agent, and take 4-4'-dimethyldiphenyliodonium hexafluorophosphate as the photoinitiator.

[0049] (2) Mixing and stirring of solid filling materials: according to the mass fraction ratio of 50% solid lubricating material, 48% curing agent, and 2% photoinitiator, each material is packed in the ball mill tank 21 of the planetary ball mill, and zirconia ceramics are added Grinding balls 22 (mixed according to the number ratio of 6mm, 10mm, and 15mm diameters of the grinding balls is 25:10:1...

Embodiment 2

[0053] Example 2: Use the composite lubricating structure obtained in Example 1 above to conduct a friction and wear test to investigate its anti-friction and anti-wear performance and compressive performance, and compare the ordinary texture without filling with the composite lubrication obtained by using traditional hot filling structure for comparison.

[0054] The test conditions are: room temperature; rotational speed 120r / min; load 100N; test time 1h, the obtained results are as follows Figure 7 and Figure 8 shown. The results show that the composite lubricating structure obtained by the electron beam curing method is smaller than the ordinary texture or the composite lubricating structure obtained by the traditional thermal curing method in terms of friction coefficient and bearing pad sample wear, indicating that the composite lubricating structure obtained by the electron beam curing method has Better anti-friction and anti-wear properties.

Embodiment 3

[0055] Embodiment 3: Using the composite lubricating structure obtained in the above-mentioned embodiment 1, a friction and wear test was carried out to investigate its compressive bearing performance, and a composite lubricating structure obtained by using traditional hot filling was used as a comparison.

[0056] The test conditions are: room temperature; speed 120r / min; loads 100N, 200N, 300N, 400N; test time 1h, the obtained results are as follows Figure 9 shown. The results show that under different loads, the friction coefficient of the composite lubrication structure obtained by the electron beam curing method is lower than that of the thermal curing method, indicating that the composite lubrication structure obtained by the electron beam curing method has better compressive bearing capacity.

Abstract

The invention discloses a processing method for a composite lubricating structure of a sliding bearing based on electron beam curing. The method comprises the following steps: (1) preparation of a solid filling material: in which titanium diboride and zinc borate are taken as solid lubricating materials, and the mass ratio of titanium diboride to zinc borate is (1-4): (1-4); a solid lubricating material, a curing agent and a photoinitiator are mixed according to the mass fraction of 50: (45-50): (0-5), and a solid filling material is obtained; (2) texturing the surface of a friction pair: processing a micro-texture on the surface of the friction pair by adopting a laser surface texturing technology; and (3) extruding, filling and curing the solid filling material: filling the solid filling material into the micro-texture on the surface of the friction pair, and curing by using electron beams. Titanium diboride and zinc borate powder are solidified in the microtexture on the surface of the bearing bush of the sliding bearing, a solid lubricating material is slowly released on the surface of a friction pair during friction movement, and the effects of reducing friction, resisting wear and improving the running-in quality are achieved.

Description

technical field [0001] The invention belongs to the technical field of friction and drag reduction, and in particular relates to a processing method for a composite lubricating structure of a sliding bearing based on electron beam curing. Background technique [0002] With the rapid development of industrial technology, higher and higher requirements are put forward for rotating machinery under extreme working conditions. Sliding bearings, as an important mechanical element that can support shaft parts and enable relative sliding between bearing surfaces, have important applications in occasions that require high precision, heavy loads, or structural divisions, and their tribological properties will directly affect overall performance of the machine. However, under low-speed and high-load conditions, due to the influence of factors such as start-stop or impact loads, the lubricating oil film with anti-friction and anti-wear functions between the friction pairs is destroyed,...
