Abstract
The utility model relates to a spinning-frame motor type spindle based on a bottom 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 base; the motor rotor is installed between an upper sleeve of the spindle blade base and a spinning-frame motor type spindle shell, a rotating shaft of the motor rotor extends axially to be directly used as a spindle blade, and a first magnetic ring is arranged at the bottom of the spindle blade; a second magnetic ring is arranged on the inner surface of the spindle blade base, and the first magnetic ring and the second magnetic ring have the same polarity; the position of the first magnetic ring corresponds to the position of the second magnetic ring. It can be avoided that operation characteristics of the spindle are affected by sliding friction between the spindle blade and the bottom of the spindle when the spinning-frame motor type spindle operates 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 based on bottom magnetic suspension structure.
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 based on bottom magnetic suspension structure, 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 based on bottom magnetic suspension structure 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, and the shaft extension of the rotating shaft of described rotor is directly as spindle blade, and described spindle blade bottom is provided with the first magnet ring; At the bottom of described spindle blade seat, inner surface 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 magnetic suspension structure, 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 electric motor type spindle structural representation in prior art;
Fig. 2 is electric motor type spindle structural representation 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 based on bottom magnetic suspension structure, 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, and the shaft extension of the rotating shaft of described rotor 2 is directly as spindle blade 4, and described spindle blade 4 bottoms are provided with the first magnet ring 5; Described spindle blade seat 3 end inner surface is provided with the 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 place corresponding with ingot basal surface, spindle blade bottom, allows 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 inner surface is provided with a magnet ring at the bottom of ingot.
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 in spindle blade bottom and inner surface magnet ring corresponding section at the bottom of ingot, 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 inner surface corresponding position is provided with the magnet ring of identical polar at the bottom of spindle blade bottom and ingot, 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 when high speed operation of motor, just can avoid the sliding friction at the bottom of spindle blade and ingot.
Be not difficult to find, the utility model adopts magnetic suspension structure, 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.
