Description
Technical field
This utility model belongs to fluid conveying machine technical field, is specifically related to the General balance mandrel of a kind of fast changeable, is particularly suitable for the static and dynamic equilibrium test of centrifugal impeller of pump.
Background technology
Damage to alleviate the component of machine heating caused due to imbalance, improve equipment reliability of operation, by API610 10thRegulation impeller, balancing drum and similar main rotation member should proceed to the dynamic balancing of ISO 1940-1 G2.5 level.The most each impeller is required for carrying out corresponding static balance or dynamic balance running, each impeller will a corresponding balance mandrel, again because being limited by single and mini-batch production and specifications and models are of a great variety, causing design, processing and manufacturing task heavy, stock utilization is the highest；Secondly use interference fit during the balance mandrel in routine is arranged, coordinate face long, also make to bring when dismounting many inconvenience, therefore need to be for the balance mandrel used by problem above design at ordinary times.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of device being applied to impeller static and dynamic equilibrium test, the General balance mandrel device of this fast changeable has that design is simple, easily processing, easy to assemble, versatility is high, the characteristic such as practical, can effectively improve production efficiency.
Purpose described in the utility model is achieved through the following technical solutions.
The cylindrical sections of same diameter is set on balance mandrel with threaded section alternately, balance mandrel one end has diameter to be more than the boss of each sections, quick change axle sleeve is assembled on balance mandrel, at quick change inner hole of shaft sleeve, end face and boss are by flat axially location, impeller hub endoporus is assemblied in quick change sleeve outer circle, the threaded section of the balance mandrel of corresponding impeller end face position is installed locking nut and is axially close to, and impeller other end is pushed against by the regulation bolt arranged on quick change bushing collars end face.
Described locking nut is that two halves separate the nut being assembled integrally.
Regulation bolt on quick change bushing collars is symmetrical arranged two, and the screw linked into an integrated entity by locking nut is fluting socket cap axial screw.
On the cylindrical of locking nut, symmetry has rectangular channel.
Length and the segment sizes of this balance mandrel employing universal design, i.e. axle can be general with the impeller of all size, and the design of each sections can solve owing to wheel hub through hole length of fit changes problem that still can be general；Balance mandrel is designed with matched quick change axle sleeve, endoporus coordinates with the cylindrical sections of balance mandrel, cylindrical mating holes changes with impeller hub through hole so that impeller hub hole size reacting condition, on axle sleeve rather than on balance mandrel, improves the versatility of balance mandrel；Impeller end face uses locking nut locking, uses two halves design quickly to lock at each sections.
On balance mandrel, sectional type design, also can have enough strong points, prevent unsettled when quick change axle sleeve can be made long, also prevent due to the long obsolete situation of quick change axle sleeve simultaneously, improves the versatility of balance mandrel.
Being provided with groove and two symmetrical tapped through holes on described quick change axle sleeve, groove is mainly for reducing length of fit, more efficient and convenient when making assembly or disassembly；Two symmetrical tapped through holes are in order to debug joint bolt, and regulation bolt can be used to position impeller end face and adjust impeller position in the overall assembly, in order to locking nut can preferably be locked.
The locking nut of two half-separation types is easy between each sections locking, and locking nut two halves use and are centrosymmetrically arranged, and the rectangular channel that locking nut cylindrical is opened is easy to use hook spanner locking and loose unloading.
The beneficial effects of the utility model are: by above technical scheme, solve the change due to impeller, the phenomenon needing to redesign balance mandrel and cause the production cycle to extend, also solves during dismounting impeller relatively harder simultaneously, makes whole balance mandrel versatility and replacing speed significantly improve.
Accompanying drawing explanation
With enforcement, this utility model is further described below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is locking nut structure schematic diagram of the present utility model.
In figure: balance mandrel 1, locking nut 2, quick change axle sleeve 3, impeller 4, regulation bolt 5, balancing machine 6, fluting socket cap axial screw 7, rectangular channel 8.
Detailed description of the invention
Seeing accompanying drawing, assembly method is, quick change axle sleeve 3 is loaded on the shaft shoulder position (boss) of balance mandrel 1；Impeller 4 entrance point is put on quick change axle sleeve 3, with the flange end face of quick change axle sleeve by flat；Regulation bolt 5 loaded onto by quick change axle sleeve 3 simultaneously；The locking nut 2 of separation is loaded at the thread segment of balance mandrel 1, tighten fluting socket cap axial screw 7, adjust regulation bolt 5 and make impeller 4 be in position suitable on quick change axle sleeve 3, with locking nut 5 locking positioning, again the parts installed are put on balancing machine 6, have so far assembled.Method for dismounting is, is taken off by parts, unclamps locking nut 2 and unclamps fluting socket cap axial screw 7, exiting locking nut 2；Symmetrical twisting regulates bolt 5 so that quick change axle sleeve 3 uniformly exits the cylindrical of impeller 4 and coordinates, then quick change axle sleeve 3 is exited from balance mandrel 1, and axle sleeve and the impeller of changing other models carry out static and dynamic equilibrium test.
