Description
Technical field
Field of mechanical technique is the utility model is related to, relates in particular to a kind of gear and rotary cultivator.
Background technology
The structure type of gear is varied, and species is various, as a kind of common power transmission mode, is widely used
Every field in production, life.Rotary cultivator is the cultivation machinery for completing to plough, harrow operation with tractor, because it has
Hack ability is strong, ploughs the features such as rear earth's surface is flat, and is widely used.In existing transmission device of rotary cultivator, tooth
Wheel is more to be made using ferrous materials, causes gear more heavy, during installation and removal, it is often necessary to which more people close
Make, gear could be dismounted;When carrying out gear and drive shaft assembling, it is impossible to firmly install, potential safety hazard be present.
Utility model content
For a variety of deficiencies of prior art, in order to solve the above problems, it is proposed that a kind of simple in construction, in light weight, wheel
Axle portion intensity is big, is not susceptible to deformation and the gear and rotary cultivator of service life length.
The technical solution adopted in the utility model is as follows:
A kind of gear, including integrally formed wheel teeth portion and wheel axle portion, the wheel teeth portion is spiral bevel gear, the wheel shaft
Portion is connected to the bigger diameter end of wheel teeth portion, and pedestal is provided with the wheel axle portion periphery, is set between the pedestal and wheel teeth portion
The shaft shoulder is equipped with, the axle hole of axial direction is provided with the wheel axle portion, the axle hole interior edge wheel axle portion bearing of trend is sequentially provided with interior
Spline part and drive shaft coordinate platform, and lightening recesses one are provided between the end of the wheel teeth portion and the shaft shoulder.
Further, the diameter in the internal spline portion is less than the diameter that drive shaft coordinates platform.
Further, lightening recesses two are provided between the miner diameter end of the wheel teeth portion and wheel axle portion.
Further, the internal spline portion is involute spline.
The utility model also provides a kind of rotary cultivator, including above-mentioned gear.
The beneficial effects of the utility model are:
1st, lightening recesses one are provided between the end of wheel teeth portion of the present utility model and the shaft shoulder, take turns the miner diameter end of teeth portion with
Lightening recesses two are provided between wheel axle portion, the intensity of gear can either be ensured, and can enough mitigates the weight of gear to greatest extent
Amount, makes gear weight light, easy to assemble.
2nd, pedestal is provided with wheel axle portion periphery of the present utility model, axle is provided between the pedestal and wheel teeth portion
Shoulder, bearing is arranged on pedestal, under the position-limiting action of the shaft shoulder so that bearing installation is accurate, firm.
3rd, internal spline portion is provided with axle hole of the present utility model, is not only able to make gear with drive shaft couple, Er Qiejia
Consolidate the intensity of wheel axle portion, is unlikely to deform wheel axle portion, improves mechanical efficiency, extend service life.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
In accompanying drawing:1- takes turns teeth portion, 2- wheel axle portions, 3- pedestals, the 4- shaft shoulders, 5- internal splines portion, 6- drive shafts cooperation platform, 7-

Gear, and the anglec of rotation of the wheel teeth portion 1 is left-handed 30 degree to 40 degree, preferably 35 degree, the wheel axle portion 2 is connected to wheel teeth portion
1 bigger diameter end, described take turns are provided with pedestal 3, the shaft shoulder 4 are provided between the pedestal 3 and wheel teeth portion 1 on the periphery of axle portion 2,
Bearing is arranged on pedestal 3, under the position-limiting action of the shaft shoulder 4 so that bearing installation is accurate, firm, is set in the wheel axle portion 2
There is an axial axle hole 9, the bearing of trend of 9 interior edge wheel axle portion of axle hole 2 is sequentially provided with internal spline portion 5 and is used for and drive shaft
The drive shaft of assembling coordinates platform 6, and in the present embodiment, the internal spline portion 5 is involute spline, and root portion is thick, bearing capacity
By force, the internal spline portion 5 is not only able to make gear with drive shaft couple, and strengthens the intensity of wheel axle portion 2, makes wheel axle portion 2
It is unlikely to deform, improves mechanical efficiency, extend service life, the diameter in the internal spline portion 5 is less than drive shaft and coordinates platform 6
Diameter, lightening recesses 1, the miner diameter end and wheel shaft of the wheel teeth portion 1 are provided between the end of the wheel teeth portion 1 and the shaft shoulder 4
Lightening recesses 28 are provided between portion 2, the intensity of gear can either be ensured, and can enough mitigates the weight of gear to greatest extent,
Make gear weight light, it is easy to assemble.
The present embodiment also provides a kind of rotary cultivator, the axle hole of the end insertion said gear of the drive shaft of the rotary cultivator
In 9, in the presence of drive shaft coordinates platform 6 and internal spline portion 5 so that drive shaft is firmly installed with wheel axle portion 2, and bearing is arranged on
On pedestal 3, under the positioning action of the shaft shoulder 4, installation is accurate firm, and the gear drive after assembling is stable.
It is described above, the only preferred embodiment of the utility model, when the utility model practical range can not be limited,
It is i.e. all to make equivalent changes and modifications according to the application scope, all should still it belong in the utility model covering scope.
