Abstract
The utility model discloses a stator structure of a submersible motor. A motor stator is matched with an upper guide bearing seat and a lower guide bearing seat via the front edge of a stator end ring and is coupled with the upper guide bearing seat and the lower guide bearing seat respectively through a coupling stud, the positioning front edge of the stator end ring adopts the middle hole of the stator end ring, and the coupling studs adopts M12 studs. By adopting the stator structure, the specifications of the coupling studs are improved, the coupling strength is enhanced, the length of the matching front edge is increased, a good sealing effect is achieved, the risk of motor burning caused by lack of water and stator and rotor friction is reduced, the use reliability of the motor is improved, and the service life of the motor is prolonged.
Description
Technical field:
The utility model relates to submersible motor, relates in particular to the stator of submersible motor.
Background technology:
The cardiac component stator of submersible motor cooperates with seam with upper and lower guide shaft bearing by the stator end ring, and is connected and fixed by double-screw bolt.Make motor normally, reposefully the running, stator is firmly connected with upper and lower guide shaft bearing.In the prior art, the positioning spigot of stator end ring is the step inner stopper, screw is distributed between stator end ring mesopore and the stator terminal loop mapping seam, and the problem of its existence is: 1, be subjected to the restriction of positioning spigot, the size of screw is restricted, connect double-screw bolt and can only adopt the M10 double-screw bolt, linking intensity is not enough, connects not fasteningly, easily causes the motor stator seam loosening, cause motor to leak and stator and rotor are swept phenomenons such as thorax and frequently taken place, thereby shortened the useful life of submersible motor.2, the seam axial dimension is too short, and poor sealing causes submersible motor to be prone to drainage herein, causes motor to burn because of the lack of water operation.
The utility model content:
The purpose of this utility model is to provide a kind of stator to connect fastening stator structure of submersible motor with upper and lower guide shaft bearing.
Stator structure of submersible motor of the present utility model, comprise motor stator, motor stator cooperates with seam with upper and lower guide shaft bearing by the stator end ring, connecting double-screw bolt links up described motor stator and upper and lower guide shaft bearing, it is characterized in that: the positioning spigot of stator end ring is a stator end ring mesopore, and screw is distributed on the stator end ring.
Connect double-screw bolt and adopt the M12 double-screw bolt.
The utility model directly stator end ring mesopore as positioning spigot, reach following technique effect: 1, screw no longer is subjected to the restriction of positioning spigot, and screw hole dimensions increases, and connects double-screw bolt and uses the M12 double-screw bolt, improved linking intensity, made stator and connecting of upper and lower guide shaft bearing more fastening, reliable.2, increased the axial length that cooperates seam, good sealing effect has significantly reduced that motor burns because of the lack of water operation and stator and rotor are swept the generation of thorax phenomenon, has improved the reliability that motor uses, and has prolonged motor useful life.
Description of drawings:
Fig. 1 is the prior art structural representation.
Fig. 2 is the utility model structural representation.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
Prior art stator structure of submersible motor schematic diagram as shown in Figure 1,1-stator, 2-stator end ring, 3-screw, 4-stator end ring seam.Stator cooperates with seam with upper and lower guide shaft bearing by the stator end ring, and is connected and fixed by double-screw bolt.The positioning spigot 4 of stator end ring is the step inner stopper, and screw 3 is distributed between stator end ring mesopore and the positioning spigot.Be subjected to the restriction of positioning spigot, connect double-screw bolt and can only adopt the M10 double-screw bolt, linking intensity is not enough.The seam axial dimension is also too short, and the seam sealing is bad.
Stator structure of submersible motor schematic diagram of the present utility model as shown in Figure 2,1-stator, 2-stator end ring, 3-screw, 4-stator end ring seam.Motor stator cooperates with seam with upper and lower guide shaft bearing by the stator end ring, connecting double-screw bolt links up motor stator and upper and lower guide shaft bearing, among Fig. 2, stator end ring mesopore is directly as the positioning spigot 4 of stator end ring, screw 3 is distributed on the stator end ring, the size of screw no longer is subjected to the restriction of stator end ring seam, connects double-screw bolt and uses the M12 double-screw bolt.Stator structure of submersible motor shown in Figure 2 has increased connection double-screw bolt specification, has improved linking intensity; Increased the length that cooperates seam, good sealing effect.
