Planetary carrier is a kind of preferred structural design, wherein, extends in parallel the second supporting mass is set with this supporting mass, and wherein, each planetary pinion can embed or be embedded between each two mutual opposed planetary gear bearings of two supporting masses.Therefore, these two supporting masses have large like this spacing towards central axis, make can pack at least one planetary pinion between two supporting masses.
Planetary carrier is a kind of preferred structural design, and wherein, two supporting masses interconnect or be designed to integral type by least one joint section.Especially planetary carrier is configured to, and makes whole planetary carrier or at least one supporting mass be designed to foundry goods.Planetary carrier is such structural design, and wherein, planetary carrier or at least one supporting mass are by metal or wrap metallic material and form.
Accordingly, planetary transmission also can have the planetary carrier of such formation and the planetary pinion by this planetary carrier supporting.
Planetary carrier is a kind of preferred structural design, and wherein, oil level is in planetary transmission, and wherein the recess of planetary carrier is designed to or surrounds as oil distributing hole and by oil.Can improve oil content by this oil distributing hole and join and oil circulation, therefore the lubrication effect of speed changer is improved.
Such planetary carrier is configured to, and makes it preferably only have the material that reaches necessary rigidity and intensity aequum.The geometrical shape of planetary carrier is especially designed at this, makes to manufacture, and especially Castability, processing and assembling can not become grain.When especially when utilizing the planetary carrier of FEM (finite element) calculation optimization or its supporting mass to realize, wherein in the peripheral part section in summit, bight or outside, also keep some parts of the geometrical shape of full circle, for obtaining the reference point for clamping work pieces in the time assembling.Especially can realize material save, better assembling and better can contact.Be in operation and can realize better oil circulation and reduce the moment of inertia of gyrating mass and therefore reduce synchronizing acting by this planetary carrier.
In the time of the manufacture of this planetary carrier, casting process also can be more efficient, because other foundry goods is because the shape changing has space in casting case.Pure illustratively according to can reducing by 30% weight in the contrast of the planetary carrier shown in Fig. 1 to Fig. 4 and especially also needing cutting measure to reduce by 30% cutting quality after casting.
