Between.
So it is disposed to power transmission shaft and gear wheel fixed plate 3 and the second gear wheel fixed plate 4 distribution of force ratio is more uniform,
Will cause because of unbalance stress inside that crackle etc. occurs when reaming, increase the service life.
Further, between described gear wheel fixed plate 3 and described second gear wheel fixed plate 4, multiple floor 6, Duo Gesuo is set
State the quantity of floor 6 and the gear wheel number same plate of described second gear wheel group 2;Multiple described floors 6 are equal around described power transmission shaft
Even distribution, each described floor 6 is respectively positioned between the two of which gear wheel of described second gear wheel group 2.
Arranging floor is to play reinforcement fixed effect and the effect of device intensity, the gear wheel fixed plate 4 made and described second
Gear wheel fixed plate 4 can bear bigger opposition when reaming.
Further, the diameter of the gear wheel of described 3rd gear wheel group 5 is less than the diameter of described second gear wheel group 2 gear wheel.
Use the gear wheel of relatively ting model, first expand less diameter, carried out larger diameter by the second gear wheel group 2 the most again
Reaming.
Further, gear wheel group and described second gear wheel group 2 all use welding manner to fix with described gear wheel fixed plate 3.
The mode being welded and fixed is processed fairly simple, and production cost ratio is relatively low, and fixed effect is preferable.
Such as Fig. 2, in the alternative embodiment of the present embodiment, described gear wheel fixed plate is along described first gear wheel group 8 boring direction
Front be additionally provided with the 3rd gear wheel fixed plate 9, described 3rd gear wheel fixed plate 9 is rounded, described 3rd gear wheel fixed plate 9
Central axis and the central axis conllinear of described power transmission shaft;Described 3rd gear wheel fixed plate 9 is away from the one of described first gear wheel group 8
Side is fixed with the 4th gear wheel group 10, and described 4th gear wheel group 10 includes the gear wheel that multiple model is identical, described 4th gear wheel group 10
Gear wheel be uniformly distributed around described power transmission shaft;The gear wheel of described 4th gear wheel group 10 is towards identical with described first gear wheel group 8;
The external diameter of described 4th gear wheel group 10 is less than institute without departing from the internal diameter of described first gear wheel group 8, the external diameter of described 3rd gear wheel plate 9
