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-
