Summary of the invention
Therefore, the object of the present invention is to provide a kind of mission case, internal gear can be stablized and be engaged in mission case securely, can boost productivity and reduce cost of production.
In order to reach above-mentioned purpose, in the present invention, on the basis that the shape of internal gear is studied, by this internal gear insert molding in box part.
Specifically, mission case of the present invention is such mission case, and it comprises: box part, and it surrounds sun gear and planetary surrounding; And the internal gear of cylindrical shape, it is fixed on the inner side of described box part with the state that spin axis is consistent with described sun gear.
The inflow limiting unit of the ring-type leant out to the inside than the end of tooth is provided with in one end of described internal gear.The outer circumferential face of described internal gear is provided with anti-slip part, is formed with more than one protuberance or recess in this anti-slip part.Further, described box part is shaping by die casting, and described internal gear insert molding is in described box part.
According to the mission case of such structure, the inflow limiting unit of the ring-type leant out to the inside than the end of tooth is provided with in one end of internal gear, this internal gear insert molding is in the box part of die cast, therefore, when core internal gear being assemblied in mould, flow into limiting unit to contact with core, so then by core and the next airtight part (ring tooth) being positioned at the tooth of the internal gear of die cavity of limiting unit can be flowed into.
Therefore, it is possible to prevent the shaping materials such as the aluminum alloy of melting from entering the situation of ring tooth, the quality of ring tooth can not be damaged, the operation that the removing etc. of melting bits is unnecessary can be saved.
Because internal gear insert molding is in box part, even if therefore guarantee formed precision and the assembly precision of height unlike pin is in the past fixed etc., also can more stablizes and engage internal gear securely.Owing to also not needing, pin is fixing waits operation, therefore very favourable in productivity and cost of production.And be provided with the anti-slip part defining more than one protuberance or recess at the outer circumferential face of internal gear, therefore, the bonding area of internal gear and box part increases, and can engage more securely.

Like this, the part of ring tooth can be formed by wire pulling method, therefore, it is possible to easily volume production internal gear, very outstanding in productivity and cost of production.
In addition, preferably, described anti-slip part is made up of the concaveconvex structure of the wire almost parallel with spin axis.
Like this, utilize anti-slip part, when effectively can bear use, put on the larger torque of internal gear, therefore, it is possible to more stably prevent the dislocation of internal gear or rock.
In addition, preferably, when described box part to have in the outside of the part being fixed with described internal gear to extend along spin axis direction and cross section give prominence to horn-like part, blowhole is set and occupies the deformation preventing portion of predetermined volume.
When have such horn-like part at box part, due to the difference at position, the amount of shaping material has imbalance, and therefore, rate of cooling during mold material cures has deviation and makes box part produce deformation.Consequently apply unbalanced deformation power to internal gear, therefore the roundness of internal gear can reduce.
On the other hand, by arranging blowhole, can eliminate imbalance to a certain degree, closing fasten at withdrawing pattern, the length of blowhole and shape are restricted greatly due to the glide direction etc. of mould.Therefore, if only by blowhole, according to the difference of the shape of shaping box part, the distribution of shaping material can produce imbalance.Therefore, by arranging deformation preventing portion separately outside blowhole, the part only leaning on blowhole to supplement can be supplemented.Consequently, the distribution homogenization of the aluminum alloy around internal gear can be made, can suppress to apply unbalanced deformation power to internal gear, the roundness of internal gear can be improved.
Such as, when described blowhole extends along spin axis direction, preferably at the end than described blowhole, described deformation preventing portion is set by inboard position.Like this, even when the end side of blowhole exists heavy section, the amount of the shaping material of heavy section also can be adjusted by deformation preventing portion, therefore, it is possible to be suppressed to the imbalance of the distribution of shaped material.
Described deformation preventing portion can be arranged to one with described internal gear.
Like this, also can obtain the effect same with anti-slip part by deformation preventing portion, therefore, it is possible to more stablized by internal gear and be engaged in box part securely.In addition, structurally can strengthen internal gear by deformation preventing portion, the roundness of internal gear can be improved further.
