Abstract
The utility model relates to a spinning frame motor type spindle adopting an extending magnetic suspension structure. The spinning frame motor type spindle comprises a motor stator and a motor rotor, wherein the motor stator is fixed on a spindle blade seat; the motor rotor is arranged between a sleeve on the upper part of the spindle blade seat and a shell body of the spinning frame motor type spindle; the shaft extension of a rotating shaft of the motor rotor is directly used as a spindle blade; a first magnetic ring is arranged at the matching part between the motor rotor and an end cover shaft hole of a motor; the outer surface of the end cover shaft hole is provided with a second magnetic ring which has the same polarity as that of the first magnetic ring; the first magnetic ring and the second magnetic ring correspond in position. According to the spinning frame motor type spindle disclosed by the utility model, the operation characteristic of the spindle is prevented from being influenced by sliding friction between the spindle blade and the spindle bottom when the spinning frame motor type spindle runs at a high speed.
Description
Technical field
The utility model relates to the electric motor type spindle in fine spining machine technical field, particularly relates to a kind of spinning frame electric motor type spindle that extends magnetic suspension structure that adopts.
Background technology
At present, occurred a kind of electric motor type spindle for fine spining machine on market, its assembly comprises (seeing accompanying drawing 1) such as spindle blade, spindle blade seat, motor stator and rotors.Wherein, spindle blade and rotor are combined as a whole, and rely on bearing and the axially stop block on electric motor end cap 7 in spindle blade seat 3 upper sleeve fixing.The rotor core of embedded permanent magnet forms rotor 2 and motor stator 1 with the motor winding around it.Electric machine casing is fixed on spindle blade seat 3, and spindle and motor are combined together.When spindle need to run up when working, there is rolling friction in the bearing between spindle blade and cylindrical central sleeve, and particularly the sliding friction meeting at the bottom of spindle blade and ingot is larger.So the power consumption of spindle is larger, and friction is easy to cause and the vibration of spindle blade 4 can affects its stable operation.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of spinning frame electric motor type spindle that extends magnetic suspension structure that adopts, and can avoid spinning frame electric motor type spindle when high-speed cruising, because of the sliding friction at the bottom of spindle blade and ingot, to affect the operation characteristic of spindle.
The utility model solves the technical scheme that its technical problem adopts: a kind of spinning frame electric motor type spindle that extends magnetic suspension structure that adopts is provided, comprises motor stator and rotor, described motor stator is fixed on spindle blade seat; Described rotor is arranged between the upper sleeve and spinning frame electric motor type spindle shell body of described spindle blade seat, the shaft extension of the rotating shaft of described rotor is directly as spindle blade, described rotor and electric motor end cap shaft hole matching place are provided with the first magnet ring, and described end cap shaft hole outer surface part is provided with the second magnet ring with the first magnet ring same polarity; The position of described the first magnet ring and the second magnet ring is mutually corresponding.
Described rotor is magnet steel embedded rotor.
On described spinning frame electric motor type spindle shell body, axially stop block is also installed.
Beneficial effect
Owing to having adopted above-mentioned technical scheme, the utility model compared with prior art, there is following advantage and good effect: the utility model adopts the floating structure of magnetic suspension, can realize rotor and the spindle blade seat of spinning frame electric motor type spindle and separate, when high speed operation of motor, avoid the sliding friction at the bottom of electric motor type spindle spindle blade and ingot.Thereby make electric motor type spindle operational efficiency high, the little and good stability of noise.
Accompanying drawing explanation
Fig. 1 is the structural representation of electric motor type spindle in prior art;
Fig. 2 is the structural representation of electric motor type spindle of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment of the present utility model relates to a kind of spinning frame electric motor type spindle that extends magnetic suspension structure that adopts, and as shown in Figure 2, comprises motor stator 1 and rotor 2, and described motor stator 1 is fixed on spindle blade seat 3; Described rotor 2 is arranged between the upper sleeve and spinning frame electric motor type spindle shell body of described spindle blade seat 3, the shaft extension of the rotating shaft of described rotor 2 is directly as spindle blade 4, described rotor 2 is provided with the first magnet ring 5 with electric motor end cap shaft hole matching place, and described end cap shaft hole outer surface part is provided with second magnet ring 6 with the first magnet ring 5 same polarities; The position of described the first magnet ring 5 and the second magnet ring 6 is mutually corresponding.Wherein, described rotor 2 is magnet steel embedded rotor.On described spinning frame electric motor type spindle shell body, axially stop block 7 is also installed.
The utility model is all provided with the magnet ring of same polarity in the rotor place corresponding with electric motor end cap axis hole outer surface, allow them axial contact not occur because of two like magnetic poles repel each other.
Stationary part is that the electric machine stator iron of embedded line is pressed into electric machine casing, then they and spindle blade seat is connected; And at the outer surface of electric motor end cap axis hole, a magnet ring is installed.
Rotor portion is by the axially stop block on the upper sleeve of spindle blade seat and spindle shell body, rotor is fixed on to the inside of stator core, and the Embedded rotor core of magnet steel is alignd with stationary part; And at rotor part and electric motor end cap magnet ring corresponding section, the same magnet ring of another piece Magnetic Phase is installed; The shaft extension of rotating shaft is just just as the spindle of fine spining machine.
After group of motors installs, because end cap shaft hole outer surface and rotor part corresponding position are provided with the magnet ring of identical polar, due to two like magnetic poles repel each other, so rotor does not just have axial contacting with the upper sleeve of spindle blade seat, thereby just can avoid the sliding friction at the bottom of spindle blade and ingot when high speed operation of motor.
Be not difficult to find, the utility model adopts the floating structure of magnetic suspension, can realize rotor and the spindle blade seat of spinning frame electric motor type spindle and separate, and has avoided the sliding friction at the bottom of electric motor type spindle spindle blade and ingot when high speed operation of motor.Thereby make electric motor type spindle operational efficiency high, the little and good stability of noise.
