Description
Technical field
The present invention relates to booster technical fields, more particularly to a kind of band end tooth dynamic balancing mandrel and impeller installation knot
Structure.
Background technique
Impeller Parts transmit bigger torsion, realize self-centering in turbomachine and booster in order to make more compact structure
The effects of, the link position of part and transmission shaft is processed as end tooth form, when which carries out dynamic balancing duplicate removal, is adopted more
Inner bore of part is passed through with conical core shaft, part is driven by mandrel by the frictional force of part and mandrel, then carry out dynamic balancing detection.
But because part is larger sometimes, heavier-weight, inner hole is smaller, the too short situation of inner hole length, often occurs
The case where dynamic balancing unstable result, reason be across mandrel can not bear completely in use part weight occur
Small amount of deflection, influences the data judging of equipment, while interior hole length is too short, and length of fit is too when being cooperated using conical core shaft
Short, effective contact area is too small so that transmission and position it is unreliable, and this kind of method and practical set process have any different it is (real
Simultaneously self-centering is connected by end tooth with main shaft using part end tooth when border is installed) so that after dynamic balancing duplicate removal result and installation
State is inconsistent, with the presence of immeasurablel error, leads to after installation that noise is big in main shaft operational process, vibration is big, main shaft and
The dynamic balancing need of work of impeller is assembled and disassembled repeatedly, checks and does over again, and is a quality risk point.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of band end tooth dynamic balancing mandrels and impeller to pacify
Assembling structure, the present invention can imitate practical installation and require to carry out dynamic balancing measurement and duplicate removal with state.
The object of the present invention is achieved like this:
A kind of band end tooth dynamic balancing mandrel, including axis body, location nut, washer, positioning end tooth, the axis body along axial direction according to
It is secondary be the first supporting section, thread segment, auxiliary centering section, linkage section, end tooth construction section, transmission limit section, the second supporting section, it is described
First supporting section, the second supporting section are for being mounted on dynamic balancing machine as rotational support；The location nut is threadedly engaged
On the thread segment；One end clearance fit of the washer in the auxiliary centering section, other end empty set on thread segment with
The location nut fitting；The positioning end tooth covers on the end tooth construction section, the planar ends and transmission of the positioning end tooth
The end face for limiting section is bonded axially position, and the located space of impeller is formed between the flank of tooth end and washer of the positioning end tooth.
Preferably, the auxiliary centering section, linkage section, the diameter of end tooth construction section are identical, first supporting section, second
The diameter of supporting section be less than the auxiliary centering section, linkage section, end tooth construction section diameter.
Preferably, the washer is equipped with resigning annular groove, steps down for the boss to impeller end, has been adapted to end
The impeller of face boss, and the impeller without end face boss.
Preferably, the end tooth construction section of the positioning end tooth and axis body is interference fitted.
Preferably, the positioning end tooth inner hole and the auxiliary centering section of axis body, linkage section, end tooth construction section manufacture.
A kind of impeller installing for experiment of dynamic balancing, including dynamic balancing machine, impeller and with end tooth dynamic balancing core
Axis, first supporting section, the second supporting section are mounted on dynamic balancing machine, and the transmission limit section and dynamic balancing machine power connect
It connects, the impeller set is located between the flank of tooth end and washer of positioning end tooth, the end tooth and positioning end of impeller one end on axis body
The other end of tooth engagement, impeller is bonded with washer, and the path section and auxiliary centering section of impeller inner hole cooperate, and the major diameter section of impeller is empty
It covers on linkage section.
The induced way by adopting the above-described technical solution, present invention will rub (originally mandrel and part friction drives)
Dynamic balance tool is improved to the dynamic balancing mandrel with end tooth, can imitate practical installation require and state carry out dynamic balancing measurement and
Duplicate removal shortens mandrel length, reduces the consuming of material, and the positioning end tooth and axis body on dynamic balancing mandrel are separately manufactured, then
Interference fit manufactures easy to process, reduction manufacture difficulty and cost.This kind of mode also has the advantage that
The versatility of dynamic balancing mandrel is more preferable: as long as (end tooth structure is necessary for same or similar end tooth outer diameter and inner diameter
Part unanimously) is generally applicable；As long as such as a diameter of part D500 can be used as the end tooth structure of diameter D200
The tooling, but old design scheme is with regard to not all right, because diameter of part is different different to the stress of axis, in addition if two parts
Hole size it is different, even if difference 1mm, the tooling of old scheme cannot be used, but this programme just without above limitation (can not lead to
Cross end tooth and washer positioning), same Products end tooth structure is generally relatively unified, change in size also very little, so only needing
A few this patent structure both can satisfy production；
Locating effect is more preferable: the fit system of conical core shaft really cooperates remaining position to be in such a way that line contacts
Gap, especially in the case where the axial length very little of hole, effect is very poor；But end tooth cooperates included certralizing ability, while in mandrel
The structure of one auxiliary centering of upper manufacture, it is ensured that the concentricity after part combination is fine, improves locating effect；
Transmitting torsion is more reliable: it is line contact that conical core shaft, which uses, relies primarily on frictional force and drives parts turn, transmission
Effect is influenced by contact area, in the heavier situation of part, it is also possible to because mandrel amount of deflection occurs and makes transmitting torsion can not
It leans on；The dependence of end tooth connection structure is that the flank of tooth drives, and it is very reliable to transmit torsion without relative motion for the flank of tooth；
As a result truer: the mandrel of end tooth connection, because with practical state consistency of installing, so that result is truer, error
It is smaller；
Solve the problems, such as mandrel amount of deflection: when part overall length is longer, hour is cut with scissors in aperture, and mandrel has when in use centainly scratches
Degree, influence dynamic balancing as a result, end tooth mandrel because be end tooth connection, it is unrelated with aperture, it is possible to prevente effectively from the problem occur, make
It is more acurrate to obtain result.
