Description
Technical field
The invention belongs to automobile current generator technical field, specifically, the particularly skeleton of automobile generator rotor.
Background technology
Automobile generator rotor consists of the pawl utmost point, winding, skeleton, armature spindle and collector ring etc.On rotor, smear dielectric, for rotor insulation and fixed rotor skeleton and the pawl utmost point.But rotor just carries out smearing of dielectric after being generally wound around copper cash and installing the pawl utmost point, owing to there is no hole on skeleton, when smearing dielectric, copper cash only has Surface Contact dielectric, dielectric cannot infiltrate copper cash inside, causes the inner copper cash of rotor framework to be fixed.When rotor high-speed rotates, inner copper cash and external stability part copper cash can produce fracture, cause generator that not electric phenomenon occurs like this.The coil rack that Chinese patent 201220442218.9 disclosed a kind of generator amature on 31st in 08 month in 2012, this coil rack is provided with dipping lacquer hole on the confined planes at body two ends, and by dipping lacquer hole, dielectric can infiltrate the internal layer of copper cash.But the position in dipping lacquer hole is located at the inner side of skeleton flabellum in this patent, carry out after rotor assembling, the pawl utmost point can be covered dipping lacquer hole, does not therefore reach dielectric and fully permeates copper cash inside, carries out the fixing effect of copper cash.
Existing rotor framework is also provided with ledge conventionally on the baffle plate at two ends, if Chinese patent ZL201120306315.0 is in as shown on 08 22nd, 2011 disclosed skeletons, this ledge is, for the pawl utmost point, contraposition is installed, there is no fixation, when rotor high-speed rotates, due to effect of inertia, skeleton can produce skew, cause being centered around the copper cash fracture on skeleton, also can produce the unfavorable condition that generator does not generate electricity.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of dielectric can fully permeate copper cash inside, also can prevent the automobile generator rotor skeleton that copper cash ruptures.
Technical scheme of the present invention is as follows: a kind of automobile generator rotor skeleton, comprise cylindrical shell (1), in one end of cylindrical shell (1), be provided with the first baffle plate (2), this first baffle plate (2) is provided with two winding sections (6), and the periphery of the first baffle plate (2) is distributed with a plurality of the first flabellums (3) that distribute by even circumferential, the other end at cylindrical shell (1) is provided with second baffle (4), the periphery of this second baffle (4) is distributed with a plurality of the second flabellums (5) that distribute by even circumferential, the second flabellum (5) upwards misplaces in week with the first flabellum (3), on described the first baffle plate (2), be provided with two group of first hole (7), this two group of first hole (7) separation is in the both sides of two winding sections (6) line of centres, each first hole (7) is positioned between two adjacent the first flabellums (3), on described second baffle (4), be provided with two fins (8), these two fins (8) are on same straight line, on described second baffle (4), be also provided with two group of second hole (9), this two group of second hole (9) separation is in the both sides of two fins (8) line of centres, and each second hole (9) is positioned between two adjacent the second flabellums (5).
The present invention sets up hole on the first baffle plate and second baffle, each hole is between two adjacent flabellums, like this after carrying out rotor assembling, the pawl utmost point can not covered hole, and each hole can be completely outside open, and dielectric can infiltrate completely by hole the innermost layer of copper cash thus, the pawl utmost point, skeleton and copper cash can be completely fixed, and fixing fixing is good, when rotor high-speed rotates, inner copper cash and external stability part copper cash can not produce fracture; The present invention sets up a pair of fin on second baffle, this fin is stuck in pawl and extremely goes up, make skeleton and pawl extremely circumferentially fixing, even the inertia because of rotor high-speed rotation, can there is not skew or depart from the pawl utmost point in skeleton yet, thereby effectively avoided, because copper cash fracture occurs in skeleton skew, having eliminated the disadvantage that generator does not generate electricity.
Described the first hole (7) and the second hole (9) are isosceles triangle, and each angle of this isosceles triangle is fillet.Each hole moulding rule, attractive in appearance of above structure, is easy to processing and fabricating; Meanwhile, hole is large as far as possible, is conducive to dielectric and passes through.
In the periphery of each hole, be equipped with the block (10) that protrudes from corresponding baffle plate, this block (10) is " V " shape, and the tip of block (10) is towards the axial line of cylindrical shell (1).Above structure on the one hand block can snap in the breach of the pawl utmost point, and skeleton and pawl are extremely circumferentially fixed, and block coordinates with fin, makes extremely circumferentially fixing better reliability of skeleton and pawl; On the other hand, block plays protection, leaks when preventing dielectric by hole.
For simplified structure, facilitate processing and fabricating, the cross section of described fin (8) is isosceles trapezoid.
Beneficial effect: the present invention can make dielectric infiltrate the innermost layer of copper cash completely, the pawl utmost point, skeleton and copper cash are completely fixed, can realize skeleton and pawl extremely circumferentially fixing simultaneously, prevent that skeleton from skew occurring or depart from, thereby effectively prevented copper cash fracture, eliminate the disadvantage that generator does not generate electricity, there is the features such as design is ingenious, novel, simple in structure, transformation is easy, improvement cost is low, all applicable on various types of automobile generator rotors.
