Embodiment
To make the purpose, technical scheme and advantage that the utility model is implemented clearer, below in conjunction with the utility model
Accompanying drawing in embodiment, the technical scheme in the embodiment of the utility model is further described in more detail.
It is the structural representation of bearing outer ring 3 for needing to load in the utility model as shown in Figure 1 first, bearing outer ring 3
There are installation side 31 and fixed edge 32, installation side 31 protrudes the outer surface of bearing outer ring 3, and the fixed edge 32 of bearing outer ring 3 has one
Determine thickness, need to load installation side 31 when reloading.
The bearing outer ring installation side impact test external member scheme of installation of the embodiment of the utility model one is illustrated in figure 2,
It can be seen that bearing outer ring of the present utility model installation side impact test external member includes base 1 and the two parts of pressure head 1 in figure.Bottom
Seat 1 is fixedly installed in pressure testing machine (not shown), and base 1 has the fixed space 15 of bearing outer ring 3, and bearing outer ring 3 is consolidated
Surely it is arranged in the fixed space 15, base 1 plays a part of fixing bearing outer ring 3.One end of pressure head 2 and pressure testing machine
(not shown) loading end is fixed, and the other end of pressure head 2 puts on the installation side 31 of bearing outer ring, is installed by the bearing outer ring
31 loading when impact test external member is realized to the installation, the main function of pressure head 2 are to be used to apply shock loading.
The understructure schematic diagram of the embodiment of the utility model one is illustrated in figure 3,.Base 1 is integrated composition, substantially shape
Shape is " Qian " font, and it has the first protuberance 11 and the second protuberance 12, and the first protuberance 11 is parallel with the second protuberance 12
Set, have fixed space 15 between the first protuberance 11 and the second protuberance 12, bearing outer ring 3 is just arranged at fixed space 15
It is interior.
In the embodiment of the utility model one, it is respectively equipped with the first protuberance 11 and the second protuberance 12 threaded
Through hole 13 and fixing hole 14, the effect of first through hole 13 is connection pressure testing machine, and fixing hole 14 is then to be used to wear bolt
Cross after fixing hole 14 and push down bearing outer ring and fix it, therefore the internal thread matched with bolt is provided with fixing hole 14.
Further, in embodiment of the present utility model, the length that the first protuberance 11 protrudes is more than the second protuberance
12 length protruded, when loading the bearing outer ring installation side being fixed in fixed space 15 using pressure head 2, pressure head 2 and second
Protuberance 12 should not interfere.
The understructure A based on Fig. 2 as shown in Figure 4 is to visual angle schematic diagram, in the utility model, the number of fixing hole 14
Measure as two, this is due to that bearing outer ring 3 is circular configuration, after bearing outer ring 3 is placed in fixed space 15, according to one
Individual fixing hole 14 is fixed with a bolt, it is likely that bad to the fixed effect of bearing outer ring 3 so that bearing outer ring
Side 31 is installed when being applied in power, bearing outer ring 3 moves, therefore fixing hole 14 and bolt can use two or more design moulds
Formula, ensure being fixedly secured for bearing outer ring 3.
It is the pressure head structure schematic diagram of the embodiment of the utility model one as shown in Figure 5 and Figure 6, pressure head 2 is the cylinder of step
Shape structure, one end is larger, one section smaller, and the larger end of pressure head 2 is connection end 22, connection end 22 and the loading end of pressure testing machine
It is fixedly connected, connected mode sets internal thread, the outer spiral shell with pressure-loaded machine loading end using threaded connection in connection end 22
Line is used cooperatively, and the small end of pressure head 2 is loading end 21, and loading end 21 loads on installation side 31, and pressure head 2 is designed into step
Shape can then avoid producing interference between pressure head 2 and base 1.When in use, the installation side 31 of bearing outer ring need to be only fixed on
Step up to fix in base 1 and by bolt, the centering of pressure head 2 is impacted target location afterwards.
With reference to above-mentioned accompanying drawing can be seen that due to installation side 31 and base 1 the first protuberance 11 between some
Space, therefore when pressure head 2 loads on installation side 31, installation side 31 can be bent downwardly, and fixed edge 32 can produce upward power.And
Bearing outer ring of the present utility model installation 31 is hit when the design key point of impact test external member is bearing outer ring installation
When, installation side 31 is forced downwards, and bearing outer ring 3 bears upward support force, and two power are not arranged on the same straight line, and are pressed
Force tester can only apply the axial force on same straight line.The axial force on straight line can then be led to by the utility model
Moment loading is crossed, realizes that two active forces are respectively acting on bearing outer ring 3 and bearing outer ring installation side 31, successfully simulates axle
The actual loading situation of bearing outer-ring installation side 31 on the engine.
Bearing outer ring installation side impact test external member structure of the present utility model is simple, and cost is low, utilizes conventional material pressure
Force tester can complete the impact strength test on bearing outer ring installation side 31 through simple transformation, and it is strong can accurately to measure its impact
Degree.The impact that bearing outer ring installation side impact test external member of the present utility model is applicable to the disk part by performing such as a variety of bearings is strong
Degree experiment.Bearing outer ring installation side impact test external member innovative point of the present utility model is by traditional material tensile test
Machine realizes the experiment of engine component strength simulation.
Bearing outer ring installation side impact test external member of the present utility model has advantages below：
1) when the installation side 31 of bearing outer ring is hit, the support that the pressure that side 31 is subject to is born with bearing outer ring 3 is installed
Power is not on the same line, and cupping machine can only apply the axial force on same straight line, can be incited somebody to action by the utility model
Axial force on straight line realizes that two active forces are respectively acting on bearing outer ring 3 and bearing outer ring peace by moment loading
On rim 31；
2) bearing outer ring 3 need to be firmly fixed on fixture, prevent it from being moved during experiment, pass through the utility model
Can be behind fixing bearing outer ring 3, pressure head 2 is pressed in the test objective position on installation side 31 just, and base 1 is not sent out with pressure head 2
Raw interference.
It (is picture in figure that bearing outer ring of the present utility model, which installs side impact test external member in traditional material testing experiment machine,
Go out) on realize bearing outer ring installation side impact test, without purchasing special equipment again, experiment can be rapidly completed, saving
Purchase cost and human cost, the examination of traditional mechanicses performance is expanded on the basis of testing of materials testing machine original function is ensured
Test the use range of equipment, it is possible to achieve the impact of the disk part by performing such as a variety of bearings is completed on traditional material testing experiment machine
Compression test.
It is described above, optimal embodiment only of the present utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with
The scope of the claims is defined.
