Modern society generally uses sander, and the sander sold on the market is varied, and it each has different set
Meter theory, make every effort to the requirement that can reach different user.But although these sanders can substantially meet requirement, its
Motor configuration design it is all not very ingenious, sealing effectiveness is poor, phenomena such as intaking into dirt easily occurs, and then causes the parts such as bearing
Damage, operating noise is big, while also greatly shortens motor normal service life.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, there is provided a kind of smart structural design, reasonable, fitting tight,
Good sealing effect, the good sander dustproof and waterproof motor of dustproof and waterproof effect.
To achieve the above object, technical scheme provided by the utility model is:
A kind of sander dustproof and waterproof motor, it include cylinder block, rotor, upper lid, upper bearing (metal), lower cover, lower bearing and partially
Mandrel, the upper bearing (metal) are arranged on the upper end open of cylinder block by upper lid, and the lower bearing is arranged on cylinder block by lower cover
Lower ending opening, the eccentric shaft is arranged in cylinder block by upper bearing (metal) and lower bearing, and the rotor is located in cylinder block, and
It is fixed on eccentric shaft, it also includes sealing gasket, and the lower lid is provided with the bearing installation cavity for being used for installing the lower bearing, institute
Sealing gasket is stated to be enclosed in the opening of the bearing installation cavity;The peripheral position of the upper lid and the fitting surface of cylinder body phase assembling is convex
Rise and chimb is sealed on being formed, and the upper envelope groove being adapted with sealing chimb on this is provided with the cylinder block;The lower cover and gas
The peripheral position for the fitting surface that cylinder body mutually assembles convexes to form lower envelope chimb, and is provided with and the lower envelope chimb in the cylinder block
The lower envelope groove being adapted.
As a kind of improvement of the present utility model, the position radial protrusion that sealing gasket is corresponded on the eccentric shaft is formed and can pushed up
It is pressed in the support rim of sealing gasket lower surface.
As a kind of improvement of the present utility model, the sealing gasket is foam-rubber cushion.
The beneficial effects of the utility model are:The utility model smart structural design, rationally, be equipped with sealing gasket, can general
The closure of openings of bearing installation cavity on lower lid, good sealing effect, enter the possibility of bearing so as to reduce water and dust, and then
Increase the life-span of bearing, good operating stability, noise is small, accordingly also extends the service life of sander;Simultaneously upper and lower cover with
Cylinder block coordinate between add upper and lower envelope chimb and upper and lower envelope groove so that coordinate between three it is more close, so as to carry
The closed gas flow effect in cylinder block has been risen, has further lifted job stability, operating efficiency is high, beneficial to wide popularization and application.
Below in conjunction with the accompanying drawings with embodiment, the utility model is further illustrated.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is configuration schematic diagram of the present utility model.
Embodiment
Embodiment, referring to Fig. 1 and Fig. 2, a kind of sander dustproof and waterproof motor of the present embodiment offer, it includes cylinder block
1st, rotor 2, upper lid 3, upper bearing (metal) 4, lower cover 5, lower bearing 6 and eccentric shaft 7, the upper bearing (metal) 4 are arranged on cylinder block by upper lid 3
1 upper end open, the lower bearing 6 are arranged on the lower ending opening of cylinder block 1 by lower cover 5, and the eccentric shaft 7 passes through upper bearing (metal)
4 and lower bearing 6 be arranged in cylinder block 1, the rotor 2 is located in cylinder block 1, and is fixed on eccentric shaft 7, its also include it is close
Packing 8, the lower cover 5 are provided with the bearing installation cavity for being used for installing the lower bearing 6, and the sealing gasket 8 is enclosed in the bearing
In the opening of installation cavity;The peripheral position for the fitting surface that the upper lid 3 assembles with the phase of cylinder block 1 convexes to form upper envelope chimb 31,
And the upper envelope groove 11 being adapted with sealing chimb 31 on this is provided with the cylinder block 1;The lower cover 5 fills with the phase of cylinder block 1
The peripheral position for the fitting surface matched somebody with somebody convexes to form lower envelope chimb 51, and is provided with and the lower phase of envelope chimb 51 in the cylinder block 1
The lower envelope groove 12 of adaptation.
Preferably, the position radial protrusion that sealing gasket 8 is corresponded on the eccentric shaft 7 forms energy top pressure under sealing gasket 8
The support rim 71 on surface, get up position-limiting action to sealing gasket 8.Preferably, the sealing gasket 8 is preferably foam-rubber cushion, frictional force
