Description

A kind of large excavator gyration gear ring of new construction

Technical field

The utility model relates to a kind of gear ring, particularly relates to a kind of gyration gear ring being applicable to ore deposit, ground highway construction large excavator.

Background technology

Refer to Fig. 3, traditional gyration gear ring is divided into symmetrical two halves.Wherein the center of each half-ring gear offers the internal point 1 of up/down perforation, and this internal point is trapezoidal; Mounting-positioning holes 2 is positioned in the main body of gear ring, respectively has two basic change face 3 around corresponding each half-ring gear of internal point 1., is convenient to two half-ring gears and combines.Each bonding surface 3 side be provided with reinforcement plate 4, as string in gyration gear ring, prevent gear ring to be out of shape.

In actual applications, the two halves of traditional large excavator gyration gear ring are cast respectively, heat treatment respectively.Before the use, two halves ring gear machining bonding surface 3, by advance closing bolt 5 closing, integrally welded at operation field.The shortcoming of this structure and method has a lot:

1, complex manufacturing technology.Due to traditional gyration gear ring dimidiation, therefore necessary half and half making, corresponding production technology needs to carry out twice.Simultaneously in order to process qualified tooth, first two half-ring gears must be consisted of one by bonding surface 3.Broach after tooth completes, also the gear ring closed being separated again, and then will carry out half and half milling bonding surface, again conjunction, again carry out vertical Vehicle Processing, release stress, eliminates deflection, is then rolled at upper rolling tooth machine and requires size, complex technical process;

2, the production cycle is long, inefficiency.Complicated activities extends the production cycle, reduces production efficiency, is difficult to quality and the progress of guaranteeing processing gear ring;

3, cost of production is high.Complex process, the production cycle is long, and spillage of material is serious, causes the waste of great man power and material, correspondingly improves the cost of production of enterprise.

Because the defect that above-mentioned existing huge revolving gear ring exists, the present inventor is based on being engaged in the practical experience and professional knowledge that this type of product design manufacture enriches for many years, and coordinate the utilization of scientific principle, actively in addition research and innovation, to founding a kind of large excavator gyration gear ring of new structure, general existing huge revolving gear ring can be improved, make it have more practicality.Through constantly research, design, and through repeatedly studying sample and after improving, finally creating the utility model had practical value.

Summary of the invention

The purpose of this utility model is, overcomes the defect that existing huge revolving gear ring exists, and provides a kind of large excavator gyration gear ring of new structure, and technical problem to be solved makes its structure more succinct, and quality is more reliable, thus is more suitable for practicality.

The purpose of this utility model and solve its technical problem be adopt following technical scheme realize.According to the large excavator gyration gear ring of a kind of new construction that the utility model proposes, its center offers the internal point of up/down perforation, and this internal point is ladder type; Fixing hole is installed be installed in the main body of this gyration gear ring, and around internal point, wherein this gyration gear ring is global formation.

The utility model compared with prior art has obvious advantage and beneficial effect.By technique scheme, the large excavator gyration gear ring of a kind of new construction of the utility model can reach suitable technological progress and practicality, and has the extensive value in industry, and it at least has following advantages:

1, structure is simple.The gyration gear ring that the utility model proposes adopts the structure of global formation, and compared to traditional gyration gear ring, do not need support brace, and need not process bonding surface, structure is more succinct;

2, manufacture craft is simple.By the improvement of this gyration gear ring structure, adopt integral manufacturing method, i.e. monobloc cast, bulk heat treatmet, overall processing and integral installation, can reach finished product requirement;

3, production efficiency is high, and quality is more reliable.Simple manufacture craft shortens the production cycle, improves production efficiency.This gyration gear ring is the structure of global formation simultaneously, can avoid the problem occurring welding deformation;

4, cost of production is low.Technique is simple, with short production cycle, adopts integral manufacturing method, greatly can reduce the investment of human and material resources, reduces the cost of production of enterprise.

Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to technological means of the present utility model can be better understood, and can be implemented according to the content of manual, and can become apparent for allowing above and other object of the present utility model, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.

Detailed description of the invention

For further setting forth the utility model for the technological means reaching predetermined goal of the invention and take and effect, below in conjunction with accompanying drawing and preferred embodiment, to according to its detailed description of the invention of large excavator gyration gear ring of a kind of new construction that the utility model proposes, structure, feature and effect thereof, be described in detail as follows.

Fig. 1 is the front view of the large excavator gyration gear ring of a kind of new construction of the utility model.Fig. 2 is the sectional view of the A-A section of the large excavator gyration gear ring of this new construction in Fig. 1.

Refer to Fig. 1 and Fig. 2, the large excavator gyration gear ring of a kind of new construction of the utility model, its center offers the internal point 1 of up/down perforation, and this internal point 1 is in ladder type; Fixing hole 2 is installed be installed in the main body of this gyration gear ring, and around internal point 1.

Preferably, the large excavator gyration gear ring of a kind of new construction that the utility model proposes is global formation.Concrete, this gyration gear ring is specially adapted to ore deposit, ground highway construction large excavator, but the utility model is not limited to this.Only the internal point 1 of this gear ring need be set on corresponding base during practical application, and fixing hole 2 is fixing can be completed by installing, thus reduce the set-up time largely.

Concrete, because the gyration gear ring that the utility model proposes is the structure of global formation, carrying out adding man-hour, take monobloc cast, bulk heat treatmet, overall processing.Simultaneously in order to realize the structure of global formation, handling, processing, installation, take: the heat treatment after building; Stress release in processing; Chucking method during fine finishining.Compared to the processing of existing known gear ring, activities is simple, thus raises the efficiency, and shortens the process-cycle, reduces cost of production.In addition, the quality of integrally-built large excavator gyration gear ring of the present utility model is more reliable, and the problem of welding deformation can not occur.

The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
