The dynamic balancing of existing revolving cup sub-assembly debugging is after the assembling of accomplishing 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 carries out, and need repeatedly remove material, and regulate to get up to waste time and energy, and not having certain experience and skill is to be difficult to realize accurately regulating.The more important thing is and to cause crackle and stress concentration phenomenon when eliminating material and regulate; Can cause certain expendable damage to the revolving cup assembly; For the revolving cup sub-assembly of high-speed rotation, can reduce stability, reliability greatly; Reduction of service life greatly, and can damage the surface aesthetic property of revolving cup or rotor axis.
The utility model content
The purpose of the utility model is the deficiency that overcomes existing revolving cup sub-assembly; Provide a kind of dynamic balance performance and the adjustment process that can continuously, conveniently regulate the revolving cup sub-assembly can not cause crackle, stress to concentrate the revolving cup sub-assembly that reaches other microdeformations, to satisfy the requirement of high rotating speed, long-life, high stability, high reliability to the revolving cup sub-assembly.
The technical scheme that the utility model adopted is: be fit to high-revolving novel revolving cup sub-assembly, but comprise vertically being positioned on the bracing frame and by actuating unit through bearing and drive the rotating shaft of high-speed rotation and the revolving cup that is fixedly mounted on the rotating shaft top; It is characterized in that also wearing in the said rotating shaft fixing one be used for balance revolving cup offset circular eccentric disc, said eccentric disc is fixed in the rotating shaft through over-surplus fit structure, perhaps is fixed in the rotating shaft through the securing member syndeton.
Said over-surplus fit structure is: in the rotating shaft fixedly the circumferential location of eccentric disc process 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.
Said securing member syndeton is: be shaped on the screw of radial penetration on the eccentric disc, a holding screw is screwed into screw eccentric disc is fixed in the rotating shaft.
The center of gravity of said 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 the said rotating shaft.
The use principle of the utility model is: the dynamic balance performance of revolving cup tends to receive influences such as material, process; Improve the dynamic balance performance of revolving cup, the center of gravity that be through reducing revolving cup and the offset distance (being offset) of its pivot center are realized.The utility model, just can make the offset of revolving cup sub-assembly reduce, and then significantly improve the dynamic balance performance of revolving cup through suitable debugging through the eccentric disc of a known offset of additional fastening in rotating shaft.
The beneficial effect of the utility model is; The revolving cup sub-assembly that the utility model provides; Can regulate the dynamic balancing of revolving cup sub-assembly continuously, efficiently, easily, simple to operate, adjustment process can not cause parts crackle and concentrated stress phenomenon; Can not influence the microdeformation of system, satisfy the requirement of high rotating speed, long-life, high stability, high reliability; In addition, dynamic balancing adjusting device processing cost is low, and is simple in structure; Has wide promotion prospect.
