Problems solved by technology

Due to the high precision requirements of the coil spring A and the elastic tube, the manufacturing process is complicated, so the manufacturing cost is high
In addition, since the oil in the spindle foot needs to be replaced regularly, the cost of use increases

Embodiment

[0013] Example: A method for reducing axial vibration of the spinning machine spindle, figure 2 , image 3 It is the engineering diagram corresponding to this embodiment.

[0014] 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 middle part of the spindle bar 1 is inlaid with magnetic stee...

Abstract

The invention relates to a method for reducing the axial vibration of an electric spindle of a spinning machine. The shaft extension of a rotating shaft of a motor rotor directly serves as a spindle blade which is inserted into a spindle foot; magnetic steel is inlaid on the outer side of the middle part of the spindle blade inserted into the spindle foot; a magnetic ring having the same polarity with the magnetic steel is arranged on the inner part of the spindle foot and opposite to the magnetic steel inlaid on the spindle blade; the magnetic ring and the magnetic steel are mutually staggered axially; the magnetic ring is closer to the motor rotor than the magnetic steel. According to the principle that the same magnetic polarity repels, the corresponding parts of the spindle blade and the spindle foot do not contact. By the method, the axial vibration of the spindle blade can be reduced, and the whole stability is enhanced.

Description

technical field [0001] The invention relates to the technical field of structure of an electric spindle of a spinning machine, in particular to a method for reducing axial vibration of an electric spindle of a spinning machine. 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 dynamic imba...
