Abstract
The present invention relates to a kind of Combined herringbone gear structures, including axis, dextrorotation single helical gear and left-handed single helical gear, the dextrorotation single helical gear and left-handed single helical gear are oppositely oriented, it further include the spacer ring being arranged among the dextrorotation single helical gear and left-handed single helical gear, the dextrorotation single helical gear, left-handed single helical gear and spacer ring are cooperatively connected by key and axis.By a kind of Combined herringbone gear structure, can be used it is split type forge, processing method is flexible, and machining tool selection is more, saving process time, reduces costs.
Description
Technical field
The present invention relates to reducer technology fields, and in particular to a kind of Combined herringbone gear structure.
Background technique
Most herringbone bears use monoblock type formed by forging currently on the market, can use when diameter is smaller,
But if monoblock type were also used when major diameter, first is that forge weight is very big, cost would be very high, second is that bearing when gear hobbing, roll flute
Limited mass, the gear hobbing of monoblock type double helical tooth, roll flute need to look for much larger lathe, and cost increases, and process equipment also not necessarily has
Need external coordination.The left-handed gear and dextrorotation gear shape adult's word tooth of the axis of herringbone bear and the centre for being located at axis, two teeth are apart
It is only at most escape, the assembly method of this structure difficulty in assembling process is larger, and increased costs are simultaneously to equipment requirement
It is higher.
Summary of the invention
The technical problem to be solved by the present invention is overcoming the deficiencies of the prior art and provide a kind of Combined herringbone gear knot
Structure, can be used it is split type forge, it is easy to process, reduce costs.
The technical solution adopted by the present invention to solve the technical problems is: a kind of Combined herringbone gear structure, including turns
The dextrorotation single helical gear and left-handed single helical gear of moving axis and installation on the rotating shaft, the dextrorotation single helical gear and left-handed monocline
Gear is oppositely oriented, and position is equipped with spacer ring, institute between dextrorotation single helical gear and left-handed single helical gear in the rotation axis
Dextrorotation single helical gear, left-handed single helical gear and spacer ring is stated to be cooperatively connected by key and rotation axis.
As the further improvement project of the present invention, the dextrorotation single helical gear and left-handed single helical gear are to pass through whole forging
It beats, low-carbon alloy steel is made in carburizing quenching process.
As the further improvement project of the present invention, the spacer ring material is No. 45 steel.
The invention has the advantages that by a kind of Combined herringbone gear structure, can be used it is split type forge, processing side
Method is flexible, and machining tool selection is more, saves process time, reduces costs.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is structural schematic diagram of the invention.
In figure: 1, axis；2, dextrorotation single helical gear；3, spacer ring；4, left-handed single helical gear；5, key.
Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
As shown in Figure 1, a kind of Combined herringbone gear structure, including rotation axis 1 and the dextrorotation being mounted in rotation axis 1
Single helical gear 2 and left-handed single helical gear 4, the dextrorotation single helical gear 2 and oppositely oriented, the described rotation of left-handed single helical gear 4
Position is equipped with spacer ring 3 between dextrorotation single helical gear 2 and left-handed single helical gear 4 on axis 1, and this structure has vacateed gear hobbing, mill
The withdrawing slot space of tooth, so both can whole gear hobbing, roll flute, gear hobbing, roll flute can also be separated, processing method is flexible, cost
Controllably.The dextrorotation single helical gear, left-handed single helical gear and spacer ring are cooperatively connected by key and rotation axis.
The dextrorotation single helical gear 2, left-handed single helical gear 4 and spacer ring 3 are cooperatively connected by key and axis 5, when keyway is cut in milling
To tooth, guarantee two monocline tooth error of left-right rotary within the scope of 0.1mm.
Preferably, the dextrorotation single helical gear 2 and 4 material of left-handed single helical gear are low-carbon alloy steel, forged by entirety,
Carburizing quenching process is made.
Preferably, 3 material of spacer ring is No. 45 steel.Forging or steel plate cutting can be used, save 50% or more former material
Expect cost.
Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
