The utility model provides a kind of anti-rotation shaft axial float attachment means and mine railway side dump wagon, is protected with reaching Alignment pin is protected, avoids, due to the impaired caused rotating shaft play of alignment pin, reducing the purpose of maintenance times.

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.

Fig. 3 and Fig. 4 are referred to, Fig. 3 is the master for the anti-rotation shaft axial float attachment means that the utility model embodiment provides View, Fig. 4 are the side view for the anti-rotation shaft axial float attachment means that the utility model embodiment provides.

The axial float attachment means of a kind of anti-rotation shaft 2 provided by the utility model, including shaft seat 1, rotating shaft 2, alignment pin And packing ring 4.

Wherein, shaft seat 1 can be fixed in chassis composition and railway carriage composition and be able on one, and chassis is fixed in rotating shaft 2 On another in composition and railway carriage composition, rotating shaft 2 is rotatably assorted with shaft seat 1, and at least one end passes through alignment pin in rotating shaft 2 It is axially positioned on shaft seat 1, packing ring 4 is set in rotating shaft 2 and between alignment pin and shaft seat 1.

Compared with prior art, the axial float attachment means of anti-rotation shaft 2 provided by the utility model, by alignment pin with Packing ring 4 is set between shaft seat 1, by increasing capacitance it is possible to increase the contact surface between alignment pin and shaft seat 1, reduces the shearing that alignment pin is subject to Effect, the impaired probability of alignment pin deformation is reduced, so as to the phenomenon of the less axial float of rotating shaft 2, and packing ring 4 is enclosed in rotating shaft 2, Without welding, it is hardly damaged, service life length, installation replacing is simple and convenient, can greatly reduce maintenance frequency.

To enable packing ring 4 to play more preferable protection effect, while packing ring 4 is avoided to come off, in the utility model embodiment In, the radial clearance of packing ring 4 and rotating shaft 2 is less than the length that alignment pin protrudes from the part of rotating shaft 2, certainly, packing ring 4 and rotating shaft 2 Radial clearance it is the smaller the better, as shown in figure 4, in the utility model embodiment, the internal diameter 96mm of packing ring 4, rotating shaft 2 is a diameter of 95mm, therefore packing ring 4 and the radial clearance of rotating shaft 2 are only 1mm.

The exterior contour of packing ring 4 can use various shapes, such as triangle, rectangle, circle etc. as needed, to avoid Packing ring 4 influences the rotation of railway carriage, and in the utility model embodiment, projection of the packing ring 4 along the axial direction of rotating shaft 2 falls within the end of rotating shaft 2 In face.

Further optimize above-mentioned technical proposal, in the utility model embodiment, buffering is provided with least one side of packing ring 4 Device, by setting above-mentioned buffer unit further to reduce the impact that alignment pin is subject to, so that packing ring 4 plays more preferably Protective action.Preferably, packing ring 4 in the one side of alignment pin at least towards buffer unit is provided with, it is of course also possible in packing ring Buffer unit is respectively provided with 4 two faces.

Buffer unit can use flexible mechanism, such as spring or rubber blanket, can also use certainly inelastic Flexible apparatus, such as felt pan.

Above-mentioned buffer unit is only a kind of preferred embodiment that the utility model embodiment provides, actual not office It is limited to this, in addition to the above described configuration, double-decker can also be used, i.e., packing ring 4 includes two backing plates and is arranged at two Elastic component between backing plate.

Further to reduce the impact that alignment pin is subject to, in the utility model embodiment, several are provided with packing ring 4 Circumferentially distributed hollow hole, so, by setting hollow hole to mitigate the weight of packing ring 4, so as to reduce it for positioning The impact of pin.

As shown in figure 3, in the utility model embodiment, the thickness of packing ring 4 is less than between pin hole 3 and shaft seat 1 Minimum range, in this case, packing ring 4 can move freely between alignment pin and shaft seat 1, with the operation of vehicle, The collision alignment pin of meeting frequently, its contact area between alignment pin is uncontrollable, therefore, in another implementation of the utility model In example, another structure is employed, the thickness of packing ring 4 is more than the most narrow spacing between the pin hole 3 and shaft seat 1 in rotating shaft 2 From and less than ultimate range between pin hole 3 and shaft seat 1 in rotating shaft 2, it is provided with one of side surface of packing ring 4 For the U-shaped opening groove of holding locating pin, so as to increase the contact area between packing ring 4 and alignment pin as far as possible, preferably play Protect the effect of alignment pin.

Further optimize above-mentioned technical proposal, in the utility model embodiment, be provided with shaft seat 1 for packing ring The spacing annular groove of 4 radial directions.

The utility model embodiment additionally provides a kind of mine railway side dump wagon, including railway carriage composition and chassis composition, Railway carriage composition is rotatably connected by attachment means and chassis composition, wherein, attachment means are the as above anti-rotation described in any one The axial float attachment means of axle 2.

Each embodiment is described by the way of progressive in this specification, what each embodiment stressed be and other The difference of embodiment, between each embodiment identical similar portion mutually referring to.
