Abstract
The utility model relates to a front-cover sealing structure of a grinding head motor. The front-cover sealing structure comprises a motor body including a casing, a front cover and a rear cover. A motor rotating shaft is installed inside the motor body; an oil seal unit is sleeved between the front end of the front cover and the motor rotating shaft by a sealing way; and a waterproof sealing ring with a maze groove is sleeved between the front cover at the front end of the oil seal unit and the motor rotating shaft by a sealing way. The waterproof sealing ring with the maze groove enables the external world to be separated from the parts inside the front cover, so that lubricating oil can not flow out of the front cover and thus the sealing effect is realized. Meanwhile, water can be prevented from entering the motor main shaft during glass grinding; the structure can be installed easily without any compressing structure; the waterproof and dustproof design is used, so that the sealing effect is good; and the service life is long.
Description
Technical field
The utility model relates to a kind of grinding head motor, especially a kind of protecgulum hermetically-sealed construction of grinding head motor.
Background technology
At present, existing grinding head motor, its protecgulum is only tightly connected by oil sealing and machine shaft, and its sealing effectiveness is poor, easily occurs the leakage of machine oil, or the infiltration of water, impurity etc., affects machine shaft and moves.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and provides a kind of convenient for maintaining, good sealing effect, the protecgulum hermetically-sealed construction of the grinding head motor that water resistance is good.
The purpose of this utility model is achieved in that
A kind of protecgulum hermetically-sealed construction of grinding head motor, comprise motor body, motor body comprises casing, protecgulum and bonnet, machine shaft is installed in motor body, between protecgulum front end and machine shaft, sealing shroud is provided with oil sealing, it is characterized in that, between the protecgulum of described oil sealing front end and machine shaft, sealing shroud is provided with the waterproof grommet with maze trough.
Hermetically-sealed construction of the present utility model, by setting up the waterproof grommet with maze trough, and sealing circle is arranged on oil sealing front end, extraneous impurity, dust, water etc. will first just can reach oil sealing through sealing circle, but the probability that can enter oil sealing is minimum, reason is that the maze trough on waterproof grommet is comparatively tortuous, effectively the part in extraneous and protecgulum is intercepted and opened, lubricating oil can not be flowed out and reach the object of sealing, the water simultaneously playing while preventing grinding glass enters in electric machine main shaft, be easy to install without compressing structure, water proof and dust proof design good sealing effect, long service life.
The beneficial effects of the utility model are:
The protecgulum hermetically-sealed construction of the utility model grinding head motor, by setting up the waterproof grommet with maze trough, and sealing circle is arranged on oil sealing front end, extraneous impurity, dust, water etc. will first just can reach oil sealing through sealing circle, but the probability that can enter oil sealing is minimum, reason is that the maze trough on waterproof grommet is comparatively tortuous, effectively the part in extraneous and protecgulum is intercepted and opened, lubricating oil can not be flowed out and reach the object of sealing, the water simultaneously playing while preventing grinding glass enters in electric machine main shaft, be easy to install without compressing structure, water proof and dust proof design good sealing effect, long service life.
Accompanying drawing explanation
Fig. 1 is half section structural representation of the present utility model.
Fig. 2 is the enlarged drawing at A place in Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1 to Figure 2, a kind of protecgulum hermetically-sealed construction of grinding head motor, comprise motor body 1, motor body 1 comprises casing 101, protecgulum 102 and bonnet 103, machine shaft 2 is installed in motor body 1, between protecgulum 102 front ends and machine shaft 2, sealing shroud is provided with oil sealing 3, it is characterized in that, between the protecgulum 102 of described oil sealing 3 front ends and machine shaft 2, sealing shroud is provided with the waterproof grommet 4 with maze trough 401.
Hermetically-sealed construction of the present utility model, by setting up the waterproof grommet 4 with maze trough 401, and sealing circle is arranged on oil sealing front end, extraneous impurity, dust, water etc. will first just can reach oil sealing 3 through this waterproof grommet 4, but the probability that can enter oil sealing 3 is minimum, reason is that the maze trough 401 on waterproof grommet 4 is comparatively tortuous, effectively the part in extraneous and protecgulum 102 is intercepted and opened, lubricating oil can not be flowed out and reach the object of sealing, the water simultaneously playing while preventing grinding glass enters in electric machine main shaft, be easy to install without compressing structure, water proof and dust proof design good sealing effect, long service life.
Above-described specific embodiment, is only the utility model preferred embodiment, and the equivalent arrangements of such as doing according to the utility model claim, all should be technology of the present utility model and contain.
