Abstract
The utility model proposes a kind of ring gear, comprise ring body and be fixed on the several tooth bars inside ring body, described tooth bar two ends are respectively arranged with measure-alike boss and concave station, and described several tooth bar end-to-end forms a closed circle; Described tooth bar has been arranged in parallel teeth, and described teeth two ends are provided with breeze way, and described tooth surface is provided with titanium nitride coating.The utility model adopts assembling racks to become a gear ring, conveniently changes, reduce user cost when tooth bar damages, and tooth bar two ends are respectively arranged with measure-alike boss and concave station, and that tooth bar is connected is more stable; Teeth are provided with breeze way, and not easily crack in teeth end, reliability is higher, and the life-span is longer, indirectly can reduce user cost; Tooth surface is provided with titanium nitride coating and reduces friction factor.
Description
Technical field
The utility model relates to a kind of ring gear.
Background technique
Gear ring is as a kind of transmission workpiece; working environment is very severe; discontinuity; gear ring of the prior art generally adopts one-body molded or interlinkage structure, although one-body molded manufacture simply keeps in repair trouble, interlinkage structure exist gear ring easily come off, easily deformable; and link strength is not high enough; often there will be the phenomenon of fracture, these all can cause gear ring not long for working life, objectively add the user cost of gear ring.
Model utility content
The utility model makes improvements for above-mentioned prior art Problems existing, and namely problem to be solved in the utility model proposes a kind of ring gear, and this ring gear is easy to maintenance, long service life, thus reduce the user cost of gear ring.
For solving the problems of the technologies described above, a kind of ring gear of the utility model comprises: ring body and the several tooth bars be fixed on inside ring body, and described tooth bar two ends are respectively arranged with measure-alike boss and concave station, and described several tooth bar end-to-end forms a closed circle; Described tooth bar has been arranged in parallel teeth, and described teeth two ends are provided with breeze way, and described tooth surface is provided with titanium nitride coating.
As a kind of preferred version of the present utility model: in breeze way width and be less than the height of described teeth.
As a kind of preferred version of the present utility model: described titanium nitride coating thickness is 0.75 ~ 1.0um.
As a kind of preferred version of the present utility model: described ring body and described tooth bar are connected by screw.
As a kind of preferred version of the present utility model: described tooth bar number is 4.
The utility model adopts assembling racks to become a gear ring, conveniently changes, reduce user cost when tooth bar damages, and tooth bar two ends are respectively arranged with measure-alike boss and concave station, and that tooth bar is connected is more stable; Teeth are provided with breeze way, and not easily crack in teeth end, reliability is higher, and the life-span is longer, indirectly can reduce user cost; Tooth surface is provided with titanium nitride coating and reduces friction factor.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological 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 plane structure schematic diagram of a kind of ring gear of the utility model embodiment;
Fig. 2 is the perspective view of the middle rack of ring gear shown in Fig. 1;
Fig. 3 is the structural representation at the A of section of rack shown in Fig. 2 position.
In figure, sequence number corresponds to:
1, ring body, 2, tooth bar, 3, screw, 4, boss, 5, concave station, 6, teeth, 7, breeze way, 8, titanium nitride coating.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological 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.
Shown in Fig. 1 to Fig. 3, a kind of ring gear comprises: ring body 1 and four tooth bars 2 be fixed on inside ring body 1, described tooth bar 2 two ends are respectively arranged with measure-alike boss 4 and concave station 5, make tooth bar 2 fixing more stable, described several tooth bar 2 end-to-end forms a closed circle; Described tooth bar 2 has been arranged in parallel teeth 6, and described teeth 6 two ends are provided with breeze way 7, and described teeth 6 surface is provided with titanium nitride coating 8.
4 tooth bars 2 join end to end formation closed circle by the utility model in use, and each tooth bar 2 is fixed on inside ring body 1 by 2 screws, described in the utility model ring gear is when damaging appears in tooth bar 2, the tooth bar 2 of damage is carried out changing and just can normally use, instead of whole ring gear must be changed, due to teeth 6 being provided with breeze way 7, so teeth 6 not easily crack in end, reliability is higher, and the life-span is longer, indirectly can reduce user cost.
Teeth 6 surface described in the utility model is provided with titanium nitride coating 8, first Ultrasonic Cleaning oil removing is carried out to teeth 6, subsequently with metal vapor vacuum arc source technology, titanium nitride is attached to die steel surface, form titanium nitride coating 8, coating thickness is 0.75 ~ 1.0um, and preferred version is 0.75um, titanium nitride coating can reduce friction factor, in practice, also can replace titanium nitride coating with two fluidisation tungsten.
The length of described breeze way 7 is greater than width and is less than the height of described teeth 6 as shown in Figure 3.
The another kind of mode of execution of the utility model is: be fixed with 2 semicircle tooth bars 2 inside described ring body 1, each tooth bar 2 is fixedly connected with ring body 1 by 4 screws.
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.
