Embodiment 1

[0017] Embodiment 1: the method for reducing the vibration of the spinning frame motor type spindle based on the homosexual repulsion of magnetic materials, figure 2 It is the engineering diagram corresponding to this embodiment.

[0018] Among them, the stator part is to press the motor stator core containing the coil into the motor casing, and then cooperate them with the spindle foot 2 . For the rotor part, a needle bearing 8 is installed on the top of the spindle foot 2, a thrust bearing 6 is installed at the bottom of the spindle, and the tip of the spindle rod 1 is placed on the thrust bearing 6. The bottom of the ingot and the bottom end cover 5 are in one structure, and are connected with the ingot foot by screws. A sliding bearing 7 is provided between the tip of the spindle rod 1 and the spindle foot 2 for radial support. The motor rotor is placed inside the stator core, and the rotor core embedded with magnetic steel is aligned with the stator part; the outer mid...

Embodiment 2

[0019] Embodiment 2: the method for reducing the vibration of the spinning frame motor type spindle based on the homosexual repulsion of magnetic materials, image 3 It is the engineering diagram corresponding to this embodiment.

[0020] Wherein, for the stator part, the motor stator core containing the coils is pressed into the motor housing 10, and then they are matched with the spindle foot 2. The rotor part 9 is axially positioned by rolling bearings 11 arranged on the upper part of the spindle foot 2 and the motor housing 10 . The motor rotor is placed inside the stator core, and the rotor core embedded with magnetic steel is aligned with the stator; the lower surface of the spindle bar 1 is embedded with magnetic steel 3, and inserted into the spindle foot 2, and the corresponding position inside the spindle foot 2 is installed with a The magnetic ring 4 of the same polarity of the magnetic steel 3, its section is shown in Figure 4 . The shaft extension of the rotor...

Abstract

The invention relates to a spinning frame motor type spindle vibration reducing method based on magnetic damping. The shaft extension of a rotary shaft of a motor rotor directly serves as a spindle blade, the spindle blade is inserted into a spindle bolster, and the outer side of the middle position of the spindle blade inserted into the spindle bolster is inlayed with magnetic steel. A magnetic ring identical to the magnetic steel in polarity is arranged inside the spindle bolster and located at the position corresponding to the magnetic steel inlayed on the spindle blade. According to a principle of like magnetic polarity repulsion, the spindle blade is not in contact with the corresponding portion of the spindle bolster. By means of the spinning frame motor type spindle vibration reducing method based on magnetic damping, vibration existing when stress of the spindle blade is unbalanced can be reduced, and meanwhile cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of the structure of the spinning frame motor spindle, in particular to a method for reducing vibration of the spinning frame motor spindle based on magnetic damping. Background technique [0002] At present, there is a motor-type spindle for spinning frame on the market, and its components include spindle bar, spindle foot, spindle bladder, motor stator and motor rotor, etc. (see figure 1 ). Wherein, the spindle bar and the motor rotor are combined into one body, and are fixed by the bearing in the upper part of the spindle foot and the axial limit device on the motor end cover. The rotor core with embedded permanent magnets and the motor windings surrounding it constitute the rotor and stator of the motor. The motor casing is fixed on the spindle foot, so that the spindle and the motor are integrated. Due to the changing unbalanced package load on the spindle rod during operation, coupled with the dynami...
