Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.
Fig. 1 is the part-structure schematic diagram of a kind of gearbox of the utility model.
In Fig. 1, the corresponding relation of reference character is:
Passive umbrella tooth 11 first driving cog of 9 active umbrella tooth 10
12 second driving cog 13 jack shaft 14 output shafts
Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
Gearbox as shown in Figure 1, for disk type tractor, comprise input shaft and jack shaft 13, input shaft is provided with initiatively umbrella tooth 9, jack shaft 13 is provided with passive umbrella tooth 10, in gearbox working procedure, initiatively umbrella tooth 9 and passive umbrella tooth 10 are in engagement all the time, and initiatively umbrella tooth 9 and passive umbrella tooth 10 are helical bevel gear, initiatively the modulus of umbrella tooth 9 and passive umbrella tooth 10 is between 4.5 to 5.5, the gear ratio of described active umbrella tooth 9 and passive umbrella tooth 10 is between 8: 39 to 6: 29, particularly, initiatively the number of teeth of umbrella tooth 9 is 6 to 8 teeth, the number of teeth of passive umbrella tooth 11 is 29 to 39 teeth.
In technique scheme, because active umbrella tooth 9 and passive umbrella tooth 10 are helical bevel gear, therefore, angle between driving shaft and jack shaft 13 is 90 degree, for the concrete modulus of active umbrella tooth 9 and passive umbrella tooth 10, be preferably 5, initiatively the gear ratio 7: 34 of umbrella tooth 9 and passive umbrella tooth 10, namely initiatively the number of teeth of umbrella tooth 9 is 7, and the number of teeth of passive umbrella tooth 10 is 34.Through repeatedly testing proof, the active umbrella tooth 9 of this modulus and passive umbrella tooth 10, its intensity is comparatively large, can effectively prevent from damaging.
