Abstract
The invention relates to a high-speed rotor assembly capable of continuously adjusting the dynamic balance performance. The assembly provided by the invention can continuously and conveniently adjust the own dynamic balance performance, and the rotor assembly can not be subjected to cracking, stress concentration and other micro deformations in the adjustment process so as to meet the requirements for high speed, long life, high stability and high reliability. The technical scheme is as follows: the high-speed rotor assembly capable of continuously adjusting the dynamic balance performance comprises a revolving shaft which is vertically positioned on a support frame through a bearing and can be driven to rotate at high speed by an actuating unit and a rotor which is fixedly installed at the top end of the revolving shaft; and the rotor assembly is characterized in that a ring-shaped eccentric disk for balancing the eccentricity of the rotor is sleeved and fixed on the revolving shaft, and the eccentric disk is fixed on the revolving shaft via an interference fit structure or a fastener connection structure.
Description
Technical field
The present invention relates to a kind of high-speed spinning device, especially continuously the high-speed rotor sub-assembly of adjusting dynamic balance performance.
Background technology
Along with the raising of open-end spinning productivity ratio, the rotating speed of revolving cup needs to improve.General, after rotational speed of rotor is brought up to more than 100000 rev/mins, very high to dynamic balance performance, the stability requirement of revolving cup sub-assembly.
The dynamic balancing of existing revolving cup sub-assembly debugging, be after the assembling that completes the revolving cup sub-assembly, utilizes the method that eliminates the part material to carry out.The shortcoming of this debud mode is: not only the removal of material is discrete carrying out, and need to repeatedly remove material, and regulates to get up to waste time and energy, and does not have certain experience and skill to be difficult to realize fine adjustment.The more important thing is and can cause crackle and stress concentration phenomenon when eliminating material and regulate, can cause certain expendable damage to the revolving cup assembly, can greatly reduce stability, reliability for the revolving cup sub-assembly of high speed rotating, reduction of service life greatly, and can damage the surface aesthetic of revolving cup or rotor axis.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing revolving cup sub-assembly, provide a kind of can be continuously, the convenient dynamic balance performance of regulating the revolving cup sub-assembly and adjustment process can not cause crackle, stress to concentrate and the revolving cup sub-assembly of other microdeformations to the revolving cup sub-assembly, to meet the requirement of high rotating speed, long-life, high stability, high reliability.
The technical solution adopted in the present invention is: the high-speed rotor sub-assembly of adjusting dynamic balance performance continuously, but comprise by bearing and vertically be positioned on bracing frame and by actuating unit and drive the rotating shaft of high speed rotating and the revolving cup that is fixedly mounted on the rotating shaft top; It is characterized in that in described rotating shaft also wearing and fix a circular eccentric disc for balance revolving cup offset, described eccentric disc is fixed in rotating shaft by over-surplus fit structure, or is fixed in rotating shaft by the securing member syndeton.
Described over-surplus fit structure is: in rotating shaft fixedly the circumferential location of eccentric disc make up big and down small taper seat, the maximum outside diameter of taper seat is greater than 0.01 ± 0.004mm of eccentric disc internal diameter, the minimum outer diameter of taper seat is identical with the rotating shaft diameter.
Described securing member syndeton is: be shaped with the screw of radial penetration on eccentric disc, a holding screw is screwed into screw eccentric disc is fixed in rotating shaft.
The center of gravity of described eccentric disc and the offset distance of its axis are 0.1～1.0mm.
Also be provided with the spacing shaft block ring of a pair of eccentric disc in described rotating shaft.
Use principle of the present invention is: the dynamic balance performance of revolving cup tends to be subject to the impacts such as material, process; Improve the dynamic balance performance of revolving cup, center of gravity that be by reducing revolving cup and the offset distance (being offset) of its pivot center are realized.The present invention, by the additional eccentric disc of fixing a known offset in rotating shaft, by suitable debugging, just can make the offset of revolving cup sub-assembly reduce, and then significantly improve the dynamic balance performance of revolving cup.
The invention has the beneficial effects as follows, revolving cup sub-assembly provided by the invention, can regulate continuously, efficiently, easily the dynamic balancing of revolving cup sub-assembly, simple to operate, adjustment process can not cause parts crackle and concentrated stress phenomenon, can not affect the microdeformation of system, meet the requirement of high rotating speed, long-life, high stability, high reliability; In addition, dynamic balancing adjusting device processing cost is low, simple in structure; There is wide promotion prospect.
