The specific embodiment
Now will be in detail with reference to the preferred embodiments of the present invention, the example is illustrated by accompanying drawing.Though the present invention will be described in conjunction with the preferred embodiments, should be appreciated that they are not to be used to limit the present invention in this embodiment.On the contrary, the present invention will cover selectable scheme, modification and the counterpart that can be included in the spirit and scope of the present invention that limited by appended claims.
As mentioned above, for increase loading capacity and service life problem day by day, the unpractical often solution of proportional amplification guide wheel assemblies.By contrast, according to principle of the present invention,, solve this problem and get the mastery by in the size that keeps wheel, providing the one axle journal.
The one journal structure can realize the loading capacity and the increase in service life by two fundamental quantities.An amount is a rotary inertia, depends on physical size.Suppose the measure-alike of wheel, the one axle journal can make the axle journal diameter relatively large.Another amount is a Young's modulus, and is relevant with the strength of materials.The one axle journal can make it possible to make journal body with the material of modulus higher (intensity is bigger, and hardness is bigger).On the contrary, because the axle journal of a lot of prior aries must be forged and pressed or by plastic deformation otherwise to cooperate other support part, so up to the present, in guiding movement industry, for journal body, use the material of high strength or high rigidity unrealistic usually.
Importantly, can produce nonlinear advantageous effects for the size of axle journal and the change of material more than.For example, the experiment in guiding movement field shows, for a well-known actual approximation, directive wheel service life with axially and cube being inversely proportional to of radial component load combinations:
Life-span=constant/(L
f)
3
Wherein, with " L " expression load,
L
f=(L
Axially/ L
Axially, maximum)+(L
Radially/ L
Radially, maximum).
In the numeric example according to above-mentioned equation, the maximum axial of increase by 10% reaches radially bearing capacity, produces 30% life-span increase.
According to principle of the present invention, the rotary inertia and the Young's modulus that provide the one axle journal to make journal body improve, and the rotary inertia of journal body and each in the Young's modulus can increase above-mentioned maximum axial and radial load successively.Term " axle journal " also comprises axle journal as axle bush at this.
Translate into accompanying drawing now, Fig. 1 and Fig. 2 show respectively according to the perspective view of the embodiment of guide wheel assemblies of the present invention and cutaway view.Notice that Fig. 1 and Fig. 2 and all accompanying drawings are actually schematic diagram, have wherein for clarity sake omitted details.
