From the point of view of implementation result by contrasting each embodiment, embodiment 1-10 rigid is better than embodiment 11-13, because
This can be seen that the technical scheme that mode is fixedly connected with using combination belongs to more preferably scheme；And using the side of being fixedly connected of riveting
Case is more convenient simple on process implementing.In addition, planet carrier punching uses Bougainvillea spectabilis flower pattern shape and corner blossom type shape
When, installation volume, which takes, to be optimized, and the rigid best results of planet carrier, is illustrated, using the planet carrier of blossom type shape
The technical scheme of punching belongs to more preferably scheme.
It should be strongly noted that the present invention is only to illustrate part particularly preferred embodiment, those skilled in the art
Member can obtain other embodiment on the basis of the present invention with reference to prior art, in other embodiment of the present invention, riveting
The quantity of point, the mode of riveting (as riveted using TOX), the quantity of planet axis hole, planet carrier punching are laminated face shape and adopted
Mode is fixedly connected with other to combine, these can make specifically chosen according to being actually needed.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit requires rather than described above limits, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.Any reference in claim should not be considered as to the involved claim of limitation.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that those skilled in the art should for clarity
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It is appreciated that other embodiment.
