Abstract
The utility model discloses a wheel device for a double-rail circular arc-shaped rail. The wheel device comprises an external wheel, an internal wheel, a carriage and carriage axles, wherein the external wheel is connected with the internal wheel through the carriage axles. The wheel device is characterized in that the external wheel is arranged on an external rail; the internal wheel is arranged on an internal rail; the carriage axles are arranged in the horizontal direction; the external wheel and the internal wheel in the same group are parallel; and the height difference of the internal rail and the external rail is equal to the radius difference of the external wheel and the internal wheel. The device ensures that the carriage body of the carriage is not inclined and can stably run on the double-rail circular arc-shaped rail, and prevents the failures appearing on commonly used sites at present such as derailing and single wear-out failure of rails since two wheels with the same diameter fixed on the same axle run along the circular arc-shaped rail.
Description
Technical field
The utility model relates to a kind of wheel assembly for the double track arc-shaped rail, belongs to mechanical field.
Background technology
At present, the wheel assembly that much moves on the double track circuit orbit is all that the interior outside adopts the form of same diameter wheel to install.The wheel assembly of this form the upper operation of rectilinear orbit (or track of larger radius of curvature) still can, but move on the less circle of radius (or circular arc) shape track, there will be the faults such as derailing, the inefficacy of track uneven wear.The compartment of the common circular cooler trolley as sintering machine, amusement of children facility etc.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of wheel assembly for double track circular arc (or circular) track, according to the arc radius of orbit, determine inside and outside both sides wheel diameter size, solved the common wheel device and the problem that derailing, track uneven wear lost efficacy on the double track arc-shaped rail, occurred, guaranteed that wheel assembly can smooth and easyly move on double track circular arc (or circular) track.
The technical solution adopted in the utility model is: a kind of wheel assembly for the double track arc-shaped rail, comprise outboard wheels, inboard wheel, compartment, axletree, outboard wheels is connected as a whole with inboard wheel by axletree, it is characterized in that: described outboard wheels is on outer side track, inboard wheel is on inner track, described axletree is in horizontal direction, the outboard wheels of same group is parallel with inboard wheel, and the diff-H of inner track and outer side track equals the semidiameter of outboard wheels and inboard wheel.
In such scheme, the outboard wheels of described same group is same cone two faces parallel with bottom surface with plane, inboard wheel place, the dead in line of described axletree and this cone, being centered close on the same straight line of this cone summit and outer side track, inner track.
In such scheme, described wheel assembly is gone forward the back axle axis all at arc-shaped rail radially.
Principle of work: according to general knowledge, cylinder pure rolling in the plane will be walked out straight path, and cylindrical two end faces can be considered as being fixed on the wheel of two same diameter on same axis, during this two wheel pure rolling, also will walk out straight path, so be adapted at moving on rectilinear orbit; And cone in the plane pure rolling will walk out the circular trace take cone tip as the center of circle, any two sections vertical with its axis of cone can be considered as being fixed on the wheel of two different-diameters on same axis, during this two wheel pure rolling, also will walk out the circular trace take cone tip as the center of circle, so be adapted at moving on arc-shaped rail.This programme adopts small one and large one two wheels that are fixed on same axis, along arc-shaped rail, move having on two tracks of diff-H, and axletree is level, the every axle in compartment is all along the radially installation of track slewing circle, can keep the car body smooth running, not there will be the problems such as derailing, single-track wearing and tearing.
The wheel assembly for the double track arc-shaped rail that the utility model provides, the diameter of outboard wheels, the angle of two axles in compartment wheel assembly front and back, the diff-H of interior outer side track in can determining according to the given compartment operation radius of turn of design, this device is simple and practical, has avoided normally used two of present many occasions to be fixed on same diameter wheels on same axis along arc-shaped rail operation and the faults such as the derailing that occurs, the inefficacy of track uneven wear.
Below in conjunction with drawings and Examples, the utility model is described further.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
In figure, 1 is outboard wheels, and 2 is inboard wheel, and 3 is the first axletree, and 4 is the second axletree, and 5 is compartment, and 6 is outer side track, and 7 is inner track, and A is the center of outer side track, and B is the center of inner track, and C is the cone summit.
The specific embodiment
Embodiment:
Fig. 1 is the front elevation of geometric relationship of the cone axis section of wheel assembly and supposition, in figure, the vertex of a cone of the cone of supposition is raised, and the axis of cone is horizontal; Fig. 2 is the birds-eye view of compartment and wheel assembly in Fig. 1, in figure, can clearly find out two of front and back axle the non-parallel installation in this compartment, but along the radially installation of track slewing circle.
As shown in Figure 1 and Figure 2, a kind of wheel assembly for the double track arc-shaped rail, comprise outboard wheels 1, inboard wheel 2, compartment 5, axletree, outboard wheels 1 is connected as a whole with inboard wheel 2 by axletree, it is characterized in that: described outboard wheels 1 is on outer side track 6, inboard wheel 2 is on inner track 7, described axletree is in horizontal direction, the outboard wheels 1 of same group is parallel with inboard wheel 2, and the diff-H of inner track 7 and outer side track 6 equals the semidiameter of outboard wheels 1 and inboard wheel 2.
The outboard wheels 1 of described same group is same cone two faces parallel with bottom surface with inboard wheel 2 planes, place, the dead in line of described axletree and this cone, the center A of this cone summit C and outer side track, the center B of inner track are located on the same line.
Described wheel assembly is gone forward the back axle axis all along the radially installation of arc-shaped rail.
In the present embodiment, on wheel assembly, the angle of the first axletree 3 and the second axletree 4 is 30 °.
Concrete method for making is:
In concrete implementation process, outer side track slewing circle radius given in design parameters is exactly the height of the cone of the supposition of traverse in Fig. 1; The diameter of compartment outboard wheels (bull wheel) is exactly the diameter of this cone bottom surface, and the diameter of this wheel can be determined by load-carrying capacity, the diameter of axle, environment space requirement etc.; After the diameter of outboard wheels (bull wheel) is determined, then according to the geometric relationship of the cone axis section of the distance of interior outboard wheels given in design parameters and supposition, can determine the diameter of compartment inboard wheel (steamboat); The diameter of two wheels just can be determined the diff-H of interior outer side track according to the radius difference of two wheels after determining respectively; Before and after certain joint compartment, two axle axis all get final product along the radially installation of circular arc (or circular) track.
In above-mentioned relation, be formulated as:
Suppose that outer side track slewing circle radius is R, namely the cone height of supposition is H=R; The diameter of supposing outboard wheels (bull wheel) is D1; The distance of supposing the interior outboard wheels that requires is h;
As can be known according to the geometric relationship of Fig. 1: the * D1/R of the diameter D2 of inboard wheel (steamboat)=(H-h); The diff-H x of interior outer side track=(D1-D2)/2.
