Abstract
The utility model discloses a water-proof motor. The water-proof motor comprises a casing (1), wherein a front end cover (2) and a rear end cover (3) are arranged at two ends of the casing (1) respectively, a rotating shaft (4) is arranged in the center of the casing (1), a trumpet-shaped water-proof cover (5) is arranged on the outer side of the front end cover (2), an assembly hole (6) is arranged in the center of the water-proof cover (5), the assembly hole (6) of the water-proof cover (5) is tightly attached to a shaft journal (7) of the rotating shaft (4), and a lengthening boss (8) is arranged on the inner side of the assembly hole (6) of the water-proof cover (5). The water-proof motor has the advantages of being good in water proof effect, long in service life, simple in structure, low in manufacturing cost and ideal in practical effect.
Description
Technical field
The utility model relates to the superior waterproof machine of a kind of waterproof effect, belongs to motor fabrication and processing field.
Background technology
For many years, the waterproof problem of motor all is a very big difficult problem, and the waterproof measure of motor generally is to adopt dehydration to wait sealing filler to seal at present, perhaps between rotating shaft and end cap, adopts maze-type structure even other more complicated hermetically-sealed constructions.Cause sealing filler to come off easily after first kind of waterproof measure uses for a long time, influence waterproof effect; And second kind of waterproof construction complex structure, manufacturing cost are higher.Therefore how to research and develop a good water-proof effect, long service life, and waterproof machine simple in structure, cheap for manufacturing cost, the problem that industry needs to be resolved hurrily become.
The utility model content
The purpose of the utility model is, a kind of waterproof machine is provided.The utility model is good water-proof effect, long service life not only, and simple in structure, cheap for manufacturing cost, has very desirable practical function.
The technical scheme of the utility model: a kind of waterproof machine; Comprise casing; The casing two ends are respectively equipped with front end housing and rear end cap, and the central authorities of casing are provided with rotating shaft, and the described front end housing outside is provided with horn-like bucker; The central authorities of bucker are provided with a pilot hole, and the pilot hole of bucker and the axle journal of rotating shaft fit tightly; The pilot hole inboard of said bucker is provided with a lengthening boss.
In the above-mentioned waterproof machine, the cover of described bucker is along being provided with drip ring.
In the aforesaid waterproof machine, described front end housing is arranged to horn-like, and the lid of front end housing is along being provided with the male half coupling of channel form, and the outside of described casing is provided with an inner stopper, and described male half coupling and inner stopper agree with each other.
In the aforesaid waterproof machine, the central authorities of said front end housing have a bending part.
Compared with prior art; The rotating shaft of the utility model is arranged with bucker; The pilot hole inboard that bucker is horn-like and bucker is provided with a lengthening boss; The lengthening boss has increased the fitting area of bucker and rotating shaft, prevents that effectively liquid from immersing from the space between bucker and rotating shaft, improved waterproof effect; As preferentially, the cover of bucker is along the drip ring with a side direction, drip ring can stop a part from the bucker cover along the liquid that gets into motor internal, further improved waterproof effect.Further, the end cap central authorities of the utility model are provided with a bending part, and as the 3rd road waterproof measure, this structure also can stop the liquid that is not stopped by drip ring, prevents the immersion of liquid to greatest extent.Because the waterproof effect of the utility model is superior, therefore compare and have longer useful life with existing common electric machine, and simple in structure, cheap for manufacturing cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Being labeled as in the accompanying drawing: 1-casing, 2-front end housing, 3-rear end cap, 4-rotating shaft, 5-bucker, 6-pilot hole, 7-axle journal, 8-boss, 9-drip ring, 10-male half coupling, 11-inner stopper, 12-bending part.
Embodiment
Below in conjunction with embodiment the utility model is done further to specify, but not as the restriction to the utility model.
The embodiment of the utility model: a kind of waterproof machine; Shown in accompanying drawing 1, comprise casing 1, casing 1 two ends are respectively equipped with front end housing 2 and rear end cap 3; The central authorities of casing 1 are provided with rotating shaft 4; Described front end housing 2 outsides are provided with horn-like bucker 5, and the central authorities of bucker 5 are provided with a pilot hole 6, and the pilot hole 6 of bucker 5 fits tightly with the axle journal 7 of rotating shaft 4; Pilot hole 6 inboards of said bucker 5 are provided with a lengthening boss 8, and lengthening boss 8 is the axial projections at bucker pilot hole place, and molded identical with the bucker material gets; The cover of described bucker 5 is along being provided with drip ring 9, a shelves water ring be the bucker cover along the radial projection of locating, also identical with the bucker material and molded gets; Described front end housing 2 is arranged to horn-like, and the lid of front end housing 2 is along being provided with the male half coupling 10 of channel form, and the outside of described casing 1 is provided with an inner stopper 11, and described male half coupling 10 agrees with inner stopper 11 each other; The central authorities of said front end housing 2 have a bending part 12.The rotating shaft of the utility model is arranged with bucker; The pilot hole inboard that bucker is horn-like and bucker is provided with a lengthening boss; The lengthening boss has increased the fitting area of bucker and rotating shaft, prevents that effectively liquid from immersing from the space between bucker and rotating shaft, improved waterproof effect; As preferentially, the cover of bucker is along the drip ring with a side direction, drip ring can stop a part from the bucker cover along the liquid that gets into motor internal, further improved waterproof effect.Further, the end cap central authorities of the utility model are provided with a bending part, and as the 3rd road waterproof measure, this structure also can stop the liquid that is not stopped by drip ring, prevents the immersion of liquid to greatest extent.Because the waterproof effect of the utility model is superior, therefore compare and have longer useful life with existing common electric machine, and simple in structure, cheap for manufacturing cost.
