The utility model proposes a kind of castor, solve the problem that in prior art, the manufacturing expense of castor is high.
The technical solution of the utility model is achieved in that
A kind of castor, comprise nylon core wheel and be sheathed on the rubber outer ring on described nylon core wheel, described nylon wheel core outer surface is provided with mounting groove, and described rubber outer ring is located on described mounting groove; Described nylon core wheel center is provided with bearing mounting hole, described bearing mounting hole side is provided with the first cover of dust mounting hole, described bearing mounting hole opposite side is provided with the second cover of dust mounting hole, described first cover of dust mounting hole and described second cover of dust mounting hole are with the center of described bearing mounting hole for center of symmetry is symmetrical arranged, and the diameter of described bearing mounting hole is greater than the diameter of described first cover of dust mounting hole.
Further, described bearing mounting hole is provided with antifriction-bearing box.
Further, described first cover of dust mounting hole is provided with the first cover of dust.
Further, the outer end of described first cover of dust mounting hole is provided with the first draw-in groove matched with described first cover of dust.
Further, described second cover of dust mounting hole is provided with the second cover of dust.
Further, the outer end of described second cover of dust mounting hole is provided with the second draw-in groove matched with described second cover of dust.
Enforcement the beneficial effects of the utility model have:
The utility model, by adopting the structure of nylon core wheel and the combination of rubber outer ring, encases rubber outer ring by mounting groove, and what both can be made like this to connect is more fastening; Be greater than the diameter of described first cover of dust mounting hole by bearing mounting hole diameter, reduce the manufacture craft of castor, reduce the cost of manufacture of castor.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the side-looking structural representation of a kind of castor of the utility model embodiment;
Fig. 2 is the A-A sectional structure schematic diagram in Fig. 1;
Figure number and explanation thereof:
1, nylon core wheel; 2, rubber outer ring; 3, the first draw-in groove; 4, the first cover of dust mounting hole; 5, bearing mounting hole; 6, the second cover of dust mounting hole; 7, the second draw-in groove.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to figs. 1 through Fig. 2, a kind of castor that the utility model provides, the rubber outer ring 2 comprising nylon core wheel 1 and be sheathed on nylon core wheel 1, nylon core wheel 1 outside face is provided with mounting groove, and rubber outer ring 2 is located on mounting groove; Nylon core wheel 1 center is provided with bearing mounting hole 5, bearing mounting hole 5 side is provided with the first cover of dust mounting hole 4, bearing mounting hole 5 opposite side is provided with the second cover of dust mounting hole 6, first cover of dust mounting hole 4 and the second cover of dust mounting hole 6 are with the center of bearing mounting hole 5 for center of symmetry is symmetrical arranged, and the diameter of bearing mounting hole 5 is greater than the diameter of the first cover of dust mounting hole 4.It is good that nylon core wheel 1 and rubber outer ring 2 form castor load-carrying capacity, and cost is low.The making main flow of the castor of the technical program is: first, chooses antifriction-bearing box (not shown in FIG.), and antifriction-bearing box is put on mould preposition; Then, then with injection machine injection molding nylon shaping on the mould putting antifriction-bearing box; Finally, to shaping product burring and installation the first cover of dust (not shown in FIG.) and the second cover of dust (not shown in FIG.).Extra antifriction-bearing box inhibiting device can be reduced by the structure of the technical program, lower the expense of inhibiting device, also save installation procedure, thus reduce the cost of manufacture of castor.
Bearing mounting hole 5 is provided with antifriction-bearing box.Antifriction-bearing box is deep groove ball bearing, can certainly substitute according to the bearing of the operating needs of reality with other.
First cover of dust mounting hole 4 is provided with the first cover of dust.Can prevent dust from contacting with antifriction-bearing box by the first cover of dust, ensure the service life of antifriction-bearing box.First cover of dust mounting hole 4 comprises the first hole from outside to inside and the second hole, first bore dia is greater than the second bore dia, and such second hole is just equivalent to the inhibiting device of the axis of rolling, can optimize nylon wheel cored structure by the first hole, reduce the use of the nylon material of nylon core wheel 1, reduce expense.
The outer end of the first cover of dust mounting hole 4 is provided with the first draw-in groove 3 matched with the first cover of dust.First draw-in groove 3 is for clamping the first cover of dust, and the first draw-in groove 3 is annular slot, certainly can do corresponding structural adjustment according to the shape of the first cover of dust.
Second cover of dust mounting hole 6 is provided with the second cover of dust.Can prevent dust from contacting with antifriction-bearing box by the second cover of dust, ensure the service life of antifriction-bearing box.Second cover of dust mounting hole 6 comprises the 3rd hole from outside to inside and the 4th hole, 3rd bore dia is greater than the 4th bore dia, and such 4th hole is just equivalent to the inhibiting device of the axis of rolling, can optimize nylon wheel cored structure by the 3rd hole, reduce the use of the nylon material of nylon core wheel 1, reduce expense.
The outer end of the second cover of dust mounting hole 6 is provided with the second draw-in groove 7 matched with the second cover of dust.Second draw-in groove 7 is for clamping the second cover of dust, and the second draw-in groove 7 is annular slot, certainly can do corresponding structural adjustment according to the shape of the second cover of dust.
In sum, the utility model, by adopting the structure of nylon core wheel and the combination of rubber outer ring, encases rubber outer ring by mounting groove, and what both can be made like this to connect is more fastening; Be greater than the diameter of described first cover of dust mounting hole by bearing mounting hole diameter, reduce the manufacture craft of castor, reduce the cost of manufacture of castor.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
