Abstract

The invention discloses an independent direct-drive ultra-high-speed revolving cup structure with a front-arranged motor. The independent direct-drive ultra-high-speed revolving cup structure comprises a revolving cup stand frame, a revolving cup sleeve with the tail end fixed to the revolving cup stand frame, a driving module installed in the revolving cup sleeve and a revolving cup head connected with the driving module and located at the front end of the revolving cup sleeve, wherein the driving module comprises a bearing outer ring arranged in the revolving cup sleeve, a bearing inner shaft, a motor rotor fixed to the peripheral wall face, located in the revolving cup sleeve, of the revolving cup head, a motor stator fixed to the inner wall of the revolving cup sleeve and matched withthe motor rotor in installation, and a revolving cup controller. One end of the bearing outer ring is connected with the revolving cup head, and an inner shaft inlet is formed in the other end of thebearing outer ring. One end of the bearing inner shaft is fixedly connected with the revolving cup stand frame, the other end of the bearing inner shaft extends into the inner shaft inlet and is matched with the bearing outer ring through bearing balls. The invention also discloses a cluster control system of the independent direct-drive ultra-high-speed revolving cup structure with the front-arranged motor.

Description

technical field [0001] The invention relates to rotor spinning technology, in particular to an independent direct-drive ultra-high-speed rotor structure in front of a motor and a cluster control system thereof. Background technique [0002] Compared with ring spinning, rotor spinning has very prominent advantages in spinning efficiency, degree of automation and economy, and is a very important spinning method. Among them, the rotor of rotor spinning and its driving system are the key links of the whole rotor spinning. Usually, the dragon belt is used to drive, or the rotor shaft is directly driven, or the dragon belt first drives two pairs of support plates, and then the support plate rotates to drive the rotor cup. It is all driven by the dragon belt to drive many rotors to rotate together, which cannot be achieved. The rotors run individually and at different speeds. [0003] The productivity of a rotor spinning machine is strictly dependent on the rotational speed of th...

Problems solved by technology

These disadvantages are based on the corresponding rigid transmission ratios between the various parts of the machine, especially in the transition phase, in the initial phase and at the rejoining after each yarn break, but also due to all the above facts that will The increase in speed to current values ​​results in an exponential increase in the energy consumption of the overall drive

[0006] The problems of using the dragon belt drive include: (1) The driving block must bear a very large pressure of the dragon belt, and thus generate the friction force between the dragon belt and the driving block, which drives the rotor shaft to rotate, and the bearing bears very Large radial load, high noise and short service life of bearings; (2) Dragon belt drive cannot achieve independent drive of rotor cups. Generally, all rotor cups of the same textile machine are driven by only 1 or 2 dragon belts. The speed of the rotors driven by the dragon belt is basically the same, and it is impossible to achieve different rotors running at a constant speed; (3) The actual speed measurement of the existing rotor needs to be obtained by a separate speed measuring device, which is costly and more structured. Complex and low reliability; (4) The axial position of the rotor has a significant impact on the quality of the rotor spinning, and the measurement of the axial position of the rotor is a key operation monitoring; (5) The structure of the entire rotor The high level of sealing protection ensures that it is protected from dust and textile fibers in the textile environment
