Sub- length is too long, is easy to appear the problem of rotor bow difference.
Utility model content
The utility model is intended to provide a kind of rotor pressing sleeve for reducing rotor bow, solves because of rotor length
The problem of the difference of rotor bow caused by too long.
In order to achieve the above objectives, the utility model adopts the following technical solution: a kind of rotor for reducing rotor bow
The cross-sectional shape of pressing sleeve, pressing sleeve ontology is H-shaped, and pressing sleeve ontology includes columned center, the inside both ends of center
It is respectively fixedly connected with connection ring, two connection rings are parallel to each other, and keyway, the outside both ends point of center are offered in connection ring
It is not fixedly connected with fixed ring vertically, two fixed rings are parallel to each other, and screw hole, fixed ring and center are offered in fixed ring
Outer side edges along the first spacing is equipped with, the side wall on the outside of the both sides of center offers cricoid avoiding hollow groove.
The principle of this programme: when practical application, first protruding into the left end of center in main drive rotor core right pressing plate, Gu
The left side for determining ring is bonded with the main side wall for driving rotor core right pressing plate, and the right end of center protrudes into auxiliary drive rotor core left pressing plate
Interior, the right side of fixed ring is bonded with the auxiliary side wall for driving rotor core left pressing plate, and the main rivet for driving rotor core right pressing plate side wall is stretched
In the avoiding hollow groove for entering left side, the auxiliary rivet for driving rotor core left pressing plate side wall is protruded into the avoiding hollow groove on right side, is passed through using screw
The screw hole of fixed ring, so that pressing sleeve ontology is fixed on main drive rotor core right pressing plate and auxiliary drive rotor core left pressing plate respectively
Together, form new rotor pressing sleeve, then connect the new rotor pressing sleeve with shaft hot jacket interference, the inside of connection ring with turn
Axis outer surface is bonded to each other, and the keyway opened up in connection ring and shaft are keyed, and complete the assembly work to pressing sleeve ontology.
The utility model has the advantages that
1, the utility model uses the pressing sleeve ontology of H-shaped structure, and the stability of this geometry itself is good, so that pressing sleeve
The rigidity of ontology is stronger.
2, the utility model uses the pressing sleeve ontology of H-shaped structure, the positive and negative both direction of pressing sleeve ontology can be installed and be made
With reducing the difficulty of assembly, versatility is stronger.
3, the utility model passes through screw and main drive rotor core right pressing plate and the left pressure of auxiliary drive rotor core using fixed ring
Plate carries out screw connection, so that pressing sleeve ontology is fixed on main drive rotor core right pressing plate and auxiliary drive rotor core left pressing plate respectively
Together, new rotor pressing sleeve is formed, is then connect the new rotor pressing sleeve with shaft hot jacket interference, the key of shaft and connection ring
Slot is keyed, and in this way, realizes dual connection, connection is more firm, can make pressing sleeve ontology and rotor
Integral structure is formed, pressing sleeve ontology and rotor can be rotated with shaft together, be solved because rotor length is spent
The problem of the difference of rotor bow caused by length.
4, in the utility model, the installation of pressing sleeve ontology and main drive rotor core right pressing plate and auxiliary drive rotor core left pressing plate

Preferably, the outer surface of pressing sleeve ontology is fixedly connected with alloy steel layer.The material of pressing sleeve ontology is steel alloy, main drive
Rotor core right pressing plate and the auxiliary material for driving rotor core left pressing plate generally use aluminum material, and such two kinds of material differences are simultaneous
The considerations of having cared for overall structure rigidity and weight has been made ratio and has preferably been selected.If pressing sleeve ontology and two kinds of pressing plates are aluminium
The rigidity of prepared material, total is inadequate, and service life is shorter, is easily damaged.If pressing sleeve ontology and two kinds of pressing plates are
The weight of alloy steel material, entire motor will increase.
Preferably, the outer annular diameter of fixed ring is 155~158mm, and the annular diameters of fixed ring are 127~130mm, two
The distance between fixed ring is 50~52mm, and the width of the first spacing is 8~10mm.By outer annular diameter to fixed ring and interior
Ring diameter is determined, and the size of such fixed ring relatively determines that the height of fixed ring, in this way can be with two kinds in 28mm or so
Pressing plate contact, and screw is fixed with two kinds of pressing plates, the height of such fixed ring will not be too high, installation side
Just.
Preferably, the outer annular diameter of connection ring is 100~102mm, and the annular diameters of connection ring are 86~90mm, two companies
Connecing the distance between ring is 46~48mm.The thickness of connection ring will not occupy too many space, and width suitable than relatively thin in this way
It with the appearance face contact of shaft and fixation, and considers on the basis of stable connection, removes weight to greatest extent, improve
The performance of rotor.
Preferably, the outer annular diameter of avoiding hollow groove is 116~120mm, and the annular diameters of avoiding hollow groove are 103~105mm.Empty avoiding
The bulk of slot and the head of rivet match, and are suitable for the installation to two kinds of pressing plates and pressing sleeve ontology.
Preferably, the outer annular diameter of center is 127~130mm, and the annular diameters of center are 100~102mm.Center
The size of set is matched with the size of general shaft, is suitable for that pressing sleeve ontology and shaft carry out hot jacket interference connection.
