Abstract
The invention discloses a novel plastic package structure of a front end cover of a motor. The plastic package structure comprises the front end cover and a plastic package material, wherein the front end cover is provided with ventilating holes; the ventilating holes are arranged annularly along the center of a circle; a square countersink is formed between the two ventilating holes; and the plastic package material is embedded into the countersinks. The plastic package structure is simple and reasonable, high in performance and safe and reliable in running, so that the problems of poor ventilating effect, low production efficiency and high production cost of the front end cover effectively can be solved effectively, the aims of increasing effect and saving materials are fulfilled, the assembly and using requirements of the plastic package coiler motor can be met, and the defects in the prior art are overcome.
Description
Technical field
The present invention relates to a kind of existing plastic packaging coil pipe motor front end housing plastic packaging structure.
Background technology
The effect of front end housing in plastic packaging coil pipe motor has: support rotor bearing 4, support shock absorbing ring 5; For satisfying above-mentioned two kinds of functions, the front end housing structure of existing plastic packaging coil pipe motor has two kinds, and a kind of shown in Fig. 1 (a) is the outer male structure of front end housing bearing chamber, and the front end housing inside diameter is done 4 effects of support rotor bearing, and outer dia is done shock absorbing ring 5 effects of supporting; This structure can add the distance between the greater trochanter two bearings, is unfavorable for motor noise, is not suitable for the longer motor of core length; And after shock absorbing ring is placed, can influence its ventilation effect, increase electric machine temperature rise; Another kind is combination front end housing structure shown in Fig. 1 (b), comprise spring bearing 7, support shock absorbing ring 8,, the front end housing assembly has front end housing 9 and 11 two parts of front end housing boss to combine, its junction 10 combinations are melting welding or rivet, though effectively controlled distance and ventilating problem between the rotor two bearings, increased the technology manufacture difficulty, increased material cost, production efficiency is low, should not produce in enormous quantities.
Summary of the invention
At above-mentioned technical problem, the present invention proposes a kind of New-type electric machine front end housing plastic packaging structure.
In order to solve the problems of the technologies described above, technical scheme of the present invention is as follows:
A kind of New-type electric machine front end housing plastic packaging structure comprises front end housing and plastic packaging material, and described front end housing is provided with ventilation hole, and described ventilation hole is provided with square counterbore along center of circle annular array between each ventilation hole, and described plastic packaging material is embedded in described square counterbore place.
Further, described ventilation hole is provided with 5.
Further, described square counterbore is provided with 5.
Beneficial effect of the present invention is: the present invention is simple and reasonable, function admirable, safe and reliable to operation, can effectively solve the problem that the front end housing ventilation effect is bad, production efficiency is low, production cost is high, realize the purpose of synergy material-saving, can satisfy simultaneously assembling and the instructions for use of plastic packaging coil pipe motor, solve weak point of the prior art.

Embodiment
The present invention is described further below in conjunction with the drawings and specific embodiments.
As Fig. 2 ~ shown in Figure 5, a kind of motor front end housing 16 plastic packaging structures, comprise front end housing 14 and plastic packaging material 15, described front end housing 14 is provided with ventilation hole 12, described ventilation hole 12 is along center of circle annular array, be provided with square counterbore 13 between each ventilation hole 12, described plastic packaging material 15 is embedded in described square counterbore place.Described ventilation hole 12 is provided with 5.Described square counterbore 13 is provided with 5.Front end housing 14 passes through die casting together with plastic packaging material 15, and production operation is simple, and the production efficiency height is fit to mass production; The positioning and guiding of front end housing ventilation hole 12, avoid ventilation hole 12 to be sealed by plastic packaging material 15, guaranteed the good ventilation effect of motor front end housing 16 integral body, the design of the square counterbore 13 of front end housing, strengthened the bond strength of plastic packaging material 15 with front end housing 14, guarantee the coefficient of safety of motor front end housing 16 integral body, the present invention adopts said structure, compared with prior art has the following advantages: production operation is simple, the production efficiency height, shorten the production time, reduced the production number, be fit to mass production; End cap ventilation effect optimization has reduced electric machine temperature rise, has saved material cost; Increase the La Tuoli of plastic packaging material, guaranteed motor front end housing 16 general safety coefficients.
The manufacture process of motor front end housing 16 is as follows:
(1) front end housing 14 is put into mould by the ventilation hole orientation, close die;
(2) plastic packaging material 15 is put into die casting mouth place, and set the die casting parameter;
(3) through after certain dwell time, open mould, take out the plastic packaging front end housing, namely finish the making of a plastic packaging front end housing.
The above only is preferred implementation of the present invention; should be pointed out that for those skilled in the art, without departing from the inventive concept of the premise; can also make some improvements and modifications, these improvements and modifications also should be considered as in the protection range of the present invention.
Claims (3)
