Abstract
The utility model discloses a bevel gear which comprises a gear body and a conical gear ring at the left end of the gear body, wherein an internal spline is arranged in the center of the gear body; hardening layers are arranged on the surface of the conical gear ring and the surface of the internal spline; the depths of the hardening layers are 0.8mm to 1mm. The conical gear ring and the internal spline are prevented from abrasion, so that the service life of the bevel gear is effectively prolonged.
Description
Technical field
The utility model relates to umbrella gear.
Background technique
Umbrella gear is multiplex in the occasion of high-speed overload, has advantages of that stable drive, bearing capacity are high, but easy to wear because of heavy load transmission, affects working life.
Summary of the invention
Problem to be solved in the utility model is to provide umbrella gear, has good wear resistance, increases the service life.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: umbrella gear, comprise gear mass and the bevel ring gear that is located at the gear mass left end, the center of described gear mass is provided with internal spline, the surface of described bevel ring gear and the surface of internal spline are equipped with hardened layer, and the degree of depth of described hardened layer is 0.8～1mm.Avoid bevel ring gear and internal spline wearing and tearing, effectively extend the working life of umbrella gear.
Improved, the center of described gear mass is provided with the axial protuberance outstanding towards the right side, and described internal spline is located at the center of axial protuberance.Be convenient to umbrella gear is positioned.
Improved, the reference cone angle of described bevel ring gear be 76 ° 14 '.
Improved, described gear mass is provided with through hole.As oilhole.
Improved, the left end face of described gear mass is provided with the groove that is communicated with each through hole.As oil groove.
Improved, described groove is annular groove.Loop configuration makes the fluid circulation smooth and easy.
Beneficial effect:
After adopting technique scheme, this model utility umbrella gear arranges the hardened layer that the degree of depth is 0.8～1mm on the surface of bevel ring gear and internal spline, make bevel ring gear and internal spline have good wear-resisting property, effectively extends the working life of umbrella gear.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
Fig. 1 is the structural representation of the utility model umbrella gear.
Embodiment
As shown in Figure 1, umbrella gear, comprise gear mass 1, the center of gear mass is provided with the axial protuberance 4 outstanding towards the right side, the left end of described gear mass is provided with bevel ring gear 2, the reference cone angle of described bevel ring gear be 76 ° 14 ', the center of described axial protuberance is provided with internal spline 3, the surface of described bevel ring gear and the surface of internal spline are equipped with hardened layer, the degree of depth of described hardened layer is 0.8～1mm, left end face on described gear mass is provided with two through holes 6, two through holes arrange about the gear mass Central Symmetry, the left end face of described gear mass is provided with the annular groove 5 that is communicated with two through holes.
Except above preferred embodiment, the utility model also has other mode of execution, those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
