Abstract
The utility model discloses a highly sealed electric drill rotor. The highly sealed electric drill rotor comprises a rotating shaft and an iron core arranged in a central section of the rotating shaft. A junk ring whose cross section is of a semi-circular arch shape is provided on the rotating shaft under the iron core. In view of the supporting and the sealing of the junk ring, a sealed bearing is provided between the junk ring and the iron core. According to the utility model, the junk ring whose cross section is of the semi-circular arc shape is arranged on the rotor, polluted water and polluted oil are thrown out along an inner wall of a junk ring body in the rotating process, and that the polluted water and the polluted oil enter the rotor and a motor is avoided, thereby achieving the good sealing performance and extending the service lives of the electric drill and the electric drill rotor.
Description
Technical field
The utility model relates to a kind of electric drill rotor of good seal performance.
Background technology
In the technique known field, motor is a kind of calutron that electric energy and mechanical energy transform each other that is used for carrying out, and its operation logic is based on the principle of electromagnetic induction; Be widely used in the industrial and mining enterprises; Especially indispensable especially important component part in electric drill is in the use of electric drill, for to the lubricated cooling of drill bit; Usually use lubricating oil even water directly drill bit to be cooled or lubricated; The lubricating oil or even the water that in rotation, very easily non-motor are used are directly brought in the motor, cause the damage of motor, have shortened the useful life of motor.
The utility model content
The technical problem that the utility model will solve is: the electric drill rotor that a kind of good seal performance is provided.
The utility model solves the technical scheme that its technical problem adopted: a kind of electric drill rotor of high leakproofness, comprise rotating shaft and the iron core that is arranged in the middle part of the rotating shaft, and in the rotating shaft of the bottom of described iron core, be provided with the seal cup that cross section is semicircular arc.
Further, consider the support and the sealing of seal cup, the utility model is provided with sealed bearing between described seal cup and iron core.
The beneficial effect of the utility model the utility model is: the utility model is through being provided with the seal cup that cross section is semicircular arc on rotor; In the process of rotation; Sewage and sump oil are dished out along the cup inwall; Avoided entering rotor and motor internal,, prolonged the useful life of electric drill and electric drill rotor to reach excellent sealing performance.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the cross-sectional view of the utility model.
Among the figure: 1. rotating shaft, 2. iron core, 3. seal cup, 4. sealed bearing.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
The electric drill rotor of a kind of high leakproofness of the utility model as depicted in figs. 1 and 2; Comprise rotating shaft 1 and the iron core 2 that is arranged at rotating shaft 1 middle part; In the rotating shaft 1 of the bottom of described iron core 2, be provided with the seal cup 3 that cross section is semicircular arc, between described seal cup 3 and iron core 2, also be provided with sealed bearing 4.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
