Description
Technical field
The utility model belongs to Gear Manufacturing Technology field, relates to a kind of split type double helical toothWheel.
Background technology
Most herringbone bears adopt monoblock type formed by forging in the market, work as diameterWhen smaller, can adopt, if but also adopt monoblock type when major diameter, the one, forging weightMeasure very greatly, cost is very high, and the 2nd, when gear hobbing, roll flute, bear weight limited, entiretyThe gear hobbing of formula double helical tooth, roll flute need to be looked for much larger lathe, and cost raises, process equipmentAlso not necessarily there is the external coordination of needs. The left-handed gear of the axle of herringbone bear and right-hand teeth wheel formDouble helical tooth and be positioned at the centre of axle, two teeth are at a distance of being at most only escape, this structureAssembling mode difficulty in assembling process larger, cost increase to equipment requirement simultaneouslyHigh.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, providesA kind of split type herringbone bear, can split forge, solve and how to make existing herringboneGear Processing is convenient, reduces costs.
The purpose of this utility model can realize by following technical proposal: a kind of split typeHerringbone bear, comprises turning cylinder, it is characterized in that, on described turning cylinder, cover has successivelyLeft-handed single helical gear, spacer ring and dextrorotation single helical gear, have keyway on described turning cylinder,In described keyway, embed bearing pin, described left-handed single helical gear, spacer ring and dextrorotation monoclineGear is all circumferentially fixing by bearing pin and turning cylinder, and one end of described turning cylinder has ringShape gear edge, the outside of described left-handed single helical gear is resisted against annular gear along upper, describedThe other end of turning cylinder has several locating holes, in described locating hole, is inserted with alignment pin,Described alignment pin is resisted against the outside of dextrorotation single helical gear, keeps off edge and location by annularPin is axially fixed on turning cylinder left-handed single helical gear, spacer ring and dextrorotation single helical gear.
Left-handed single helical gear, spacer ring and dextrorotation single helical gear are separate machined, processing sideJust, use small-sized process equipment can carry out processing, cost is low, and passes throughThe cooperation of bearing pin, annular gear edge and alignment pin makes left-handed single helical gear, spacer ring, dextrorotation listHelical gear is positioned on turning cylinder, simple in structure, and the firm degree being connected is high.
In the split type herringbone bear of above-mentioned one, described left-handed single helical gear and the right sideRevolve single helical gear external diameter identical, outside described left-handed single helical gear and dextrorotation single helical gearFootpath is all greater than the external diameter of spacer ring. Reasonable in design.
In the split type herringbone bear of above-mentioned one, described locating hole is blind hole, instituteThe alignment pin tight fit of stating is connected in locating hole, and the outer end of described alignment pin is stretched out fixedHole, position. Tight fit is connected, and the firm degree being connected is high, ensure left-handed single helical gear, everyBetween ring and dextrorotation single helical gear, there is not gap, improve the accuracy of gear high.
In the split type herringbone bear of above-mentioned one, the quantity of described locating hole is3-6, described locating hole spaced set. The quantity of locating hole is according to actual conditionsSet, spaced set, stressedly evenly plays better locating effect.
Compared with prior art, the split type herringbone bear that the utility model provides have withLower advantage:
1, left-handed single helical gear, spacer ring and the dextrorotation monocline tooth in this split type herringbone bearWheel is all separately independent processing, easy to process, uses small-sized process equipment to enterRow processing, cost is low.
2, in this split type herringbone bear, keep off the cooperation of edge and alignment pin by bearing pin, annularMake that left-handed single helical gear, spacer ring and dextrorotation single helical gear are friction tight to be positioned on turning cylinder,Simple in structure, the accuracy of gear is high.
Brief description of the drawings
Fig. 1 is the overall structure partial sectional view of this split type herringbone bear.
In figure, 1, turning cylinder; 2, left-handed single helical gear; 3, spacer ring; 4, dextrorotation listHelical gear; 5, bearing pin; 6, annular gear edge; 7, alignment pin.
Detailed description of the invention
Below specific embodiment of the utility model by reference to the accompanying drawings, to the utility modelTechnical scheme be further described, but the utility model is not limited to these embodiment.
As shown in Figure 1, this split type herringbone bear comprises turning cylinder 1, on turning cylinder 1Cover has left-handed single helical gear 2, spacer ring 3 and dextrorotation single helical gear 4, left-handed monocline tooth successivelyWheel 2 is identical with dextrorotation single helical gear 4 external diameters, left-handed single helical gear 2 and dextrorotation monocline toothThe external diameter of wheel 4 is all greater than the external diameter of spacer ring 3.
On turning cylinder 1, there is keyway, in keyway, embed bearing pin 5, left-handed single helical gear 2,Spacer ring 3 and dextrorotation single helical gear 4 are all circumferentially fixing by bearing pin 5 and turning cylinder 1, turnOne end of moving axis 1 has annular gear along 6, and the outside of left-handed single helical gear 2 is resisted against ringShape is kept off along on 6, and in the present embodiment, the other end of turning cylinder 1 has four locating holes,Four locating hole spaced sets, in actual production, the quantity of locating hole can be threeIndividual or six, locating hole is blind hole, is inserted with alignment pin 7 in locating hole, alignment pin 7Tight fit is connected in locating hole, and locating hole is stretched out in the outer end of alignment pin 7, alignment pin 7Outer end be resisted against the outside of dextrorotation single helical gear 4, keep off along 6 and alignment pin by annular7 make left-handed single helical gear 2, spacer ring 3 and dextrorotation single helical gear 4 be axially fixed in turning cylinderOn 1.
