Embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
Consulting Fig. 1-6, is an embodiment of spring coupling working condition tests platform proposed by the invention, and wherein Fig. 1 and Fig. 5 are that the main optical axis is to sectional structure schematic diagram.
Spring coupling working condition tests platform comprises stand 1, at stand 1, has power source 2 and loadwheel 3, between power source 2 and loadwheel 3, is connected with spring coupling 4; On stand 1, be provided with position-movable structure 20, in the present embodiment, power source 2 is fixed in position-movable structure 20, shown in Figure 1.
By being arranged on loadwheel 3, power source 2, spring coupling 4 and the position-movable structure 20 on stand 1, can realize the working condition experimenting of spring coupling, and data are carried out the analysis of quantitative and qualitative by experiment, the optimization that is conducive to spring coupling improves; Move position by position-movable structure 20 on stand 1, realize between the axle of power source 2 and the axle of loadwheel 3 and occur different deviation kinds and different deviates, make the working condition experimenting of spring coupling can choose different parameter research experiment.
The deviation kind of spring coupling has axial deviation, radial missing and angle deviation; Radial missing is exactly that the axle of power source 2 and the axle of loadwheel 3 are parallel to each other, but decentraction; Axial deviation be exactly the axle of power source 2 and the axle of loadwheel 3 be coaxial, but the distance distance of being separated by has deviation.Angle deviation is exactly the axle decentraction of axle and the loadwheel 3 of power source 2, and has a certain degree mutually.In spring coupling real work, may be to have two kinds or three kinds of deviations simultaneously; In experiment, we study respectively various deviations, and the impact of different deviates on the stress distribution on spring coupling and tired situation.
In other embodiment, also loadwheel 3 can be fixed in position-movable structure 20, or power source 2 and loadwheel 3 are separately fixed in two position-movable structures 20.
On spring coupling working condition tests platform in the present embodiment, can use actual spring coupling, but when actual spring coupling size is larger, the size of bulk testing platform is just too huge.So we test after can larger-size spring coupling is scaled, because we are mainly stress distribution and the tired situation of research spring coupling 4 when there is deviation, thereby also the structure of spring coupling can be simplified, such as axle 43 and the becket 42 that is positioned at rubber ring 41 both sides are made of one, shown in Figure 1.
