Abstract
The invention provides a bevel gear combination in an integral structure, and the bevel gear combination is formed by a plurality of cylindrical bevel gears with same modulus and number of teeth. A plurality of cylindrical bevel gears are divided into two groups of left-hand and right-hand, and the two groups of the bevel gears are oppositely arrayed and assembled onto a shaft to form the structural bevel gear combination. Or, after a plurality of cylindrical bevel gears are divided into two groups of left-hand and right-hand, two cylindrical bevel gears are oppositely assembled into a pair according to the left-hand and right-hand, and a plurality of pairs of bevel gears are symmetrically assembled onto a shaft to form the structural bevel gear combination.
Description
One, technical field
The present invention and a kind of same modulus, the same to number of teeth, multiple cylindric spiral gears be combined into an Integral-structure type helical gear combination gear, belong to mechanical manufacturing field.
Two, background technique
At present, known cylindrical gears has straight-tooth, helical teeth, herringbone tooth, spur gear load concentration, transmission is not steady, helical gear load distribution uniform, stable drive, bearing capacity is higher, but in the time of transmission, has axial force to produce, and just adopts herringbone gear in order to eliminate axial force, but herringbone gear processing is more difficult, and precision is lower.
Three, summary of the invention
In order to overcome existing spur gear wheel, cylindric spiral gear, the shortcoming and defect of herringbone gear, the invention provides a kind of knockdown cylindric spiral gear, this gear not only manufacture difficulty is little, and has fine transmission stability, in the time rotating, do not produce axial force, bearing capacity is high, and noise is little, long service life.
The technical solution adopted for the present invention to solve the technical problems is: multiple same moduluses, be divided into two groups of left-handed and dextrorotation with the cylindric spiral gear of the number of teeth, then these two groups of helical gears arranged in opposite directions and are assembled on an axle, become structural formula helical gear combination gear.Also the multiple same moduluses of handlebar, be divided into two groups of left-handed and dextrorotation with the cylindric spiral gear of the number of teeth after, again they are combined into a pair of by left-handed and two helical gears dextrorotation in opposite directions, then being assembled on an axle of so multipair helical gear symmetric type, become structural formula helical gear combination gear.
The invention has the beneficial effects as follows; Adopt multiple cylindric spiral gears to be combined into an Integral-structure type helical gear combination gear, its single-piece helical gear manufacture difficulty is little, easy to assembly, in use in the time of any single-piece gear failure wherein, can single-piece change this gear, overhaul convenient and swiftly, save material, this helical gear combination gear is adapted at using in the middle of various mechanical transmission, in the middle of the speed reducer of especially applicable large-scale heavy duty lotus and driving mechanism, uses.
Four, accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described;
Fig. 1. be the front view of helical gear combination gear of the present invention.
Fig. 2. be first embodiment's plan view of helical gear combination gear.
Fig. 3. be second embodiment's plan view of helical gear combination gear.
In figure: 1. helical gear combination gear, 2. central gear axis, 3. interior positioning key, the 4. shaft shoulder, 5. left-hand helical gear, 6. dextrorotation helical gear.
Five, embodiment
In the drawings, helical gear combination gear (1) is arranged on central gear axis (2), on central gear axis (2), process keyway, each gear center hole in helical gear combination gear (1) processes respectively positioning spline, helical gear combination gear (1) is to be connected together by interior positioning key (3) and central gear axis (2), the shaft shoulder (4) plays position-limiting action to helical gear combination gear (1), helical gear combination gear (1) has two kinds of compound modes, the first is that left-hand helical gear (5) is divided into two groups with dextrorotation helical gear (6), then these two groups of helical gears are arranged in opposite directions and are assembled on central gear axis (2), to be left-hand helical gear (5) be combined into a pair of with dextrorotation helical gear (6) take two as unit the second in opposite directions, then arrange and be assembled on central gear axis (2).
Claims (2)
1. a helical gear combination gear, is characterized in that; With same modulus, be divided into two groups of left-handed and dextrorotation with multiple cylindric spiral gears of the number of teeth, then these two groups of helical gears are arranged in opposite directions and are assembled on an axle, become structural formula helical gear combination gear.
2. helical gear combination gear according to claim 1, is characterized in that; After being divided into two groups of left-handed and dextrorotation multiple same moduluses, with the cylindric spiral gear of the number of teeth, again they are combined into a pair of by left-handed and two helical gears dextrorotation in opposite directions, then being assembled on an axle of so multipair helical gear symmetric type, become structural formula helical gear combination gear.
