Abstract
The utility model discloses a novel road wheel device, which comprises a road wheel. A bearing, a double thread hollow shaft and a load-bearing shaft are arranged on the road wheel from outside to inside sequentially. A shaft cover check ring is arranged on one end of the load-bearing shaft. When a double thread load-bearing shaft is arranged on the load-bearing shaft, the load-bearing surface of the load-bearing shaft is increased, so that bending of the load-bearing shaft is avoided, and bearing capacity of the bearing is increased, and therefore, the device is convenient to replace.
Description
Technical field
The utility model relates to the road wheel technical field, relates in particular to a kind of novel caster device.
Background technique
Caster device installation and maintenance of the prior art are inconvenient, and the relatively more difficult inconvenience replacing of maintenance and sealing are relatively poor, and bearing capacity is relatively poor, and the easy deformed damaged of reach causes equipment to work easily.
The model utility content
Technical problem to be solved in the utility model provides a kind of novel caster device that increases bearing capacity.
For achieving the above object, the utility model provides following technological scheme: a kind of novel caster device, comprise road wheel, and the road wheel ecto-entad is provided with bearing, double thread screw hollow shaft and reach successively, and described reach one end is provided with the shaft-cup back-up ring.
Preferably, described shaft-cup back-up ring area is greater than described reach diameter area.
Preferably, be respectively equipped with front cover and rear end cover on the screw thread of described double thread screw hollow shaft.
Preferably, described rear end cover is provided with a pair of locating stud, and described locating stud is built in described road wheel.
Adopt the beneficial effect of above technological scheme to be: in reach was installed the double thread screw reach, thing carrier bearing section increased, and has avoided the reach buckling phenomenon, has increased bearing capacity, is convenient for changing.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Wherein, 1-road wheel, 2-bearing, 3-double thread screw hollow shaft, 4-reach, 5-shaft-cup back-up ring, 6-front cover, 7-rear end cover, 8-locating stud.
Embodiment
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not consist of the restriction to the utility model protection domain.
Describe preferred implementation of the present utility model in detail below in conjunction with accompanying drawing 1: a kind of novel caster device, comprise road wheel 1, be provided with successively bearing 2, double thread screw hollow shaft 3 and reach 4 at road wheel 1 ecto-entad, be provided with shaft-cup back-up ring 5 at reach 4 one ends, shaft-cup back-up ring area 5 is greater than described reach 4 diameter areas, screw thread at double thread screw hollow shaft 3 is respectively equipped with front cover 6 and rear end cover 7, is provided with a pair of locating stud 8 at rear end cover 7, and locating stud 8 is built in road wheel 1.
Adopt the beneficial effect of above technological scheme to be: in reach was installed the double thread screw reach, thing carrier bearing section increased, and has avoided the reach buckling phenomenon, has increased bearing capacity, is convenient for changing.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
