Abstract
The utility model proposes a kind of industrial big fan chassis assembly and the connection tapered sleeve of motor shaft, including the tapered sleeve conical section in circular cone structure, end face boss, breach, keyway and screw, the tapered sleeve conical section side wall is provided with the breach along longitudinal direction, the hole inwall of breach opposite side is provided with keyway, has screw on the end face boss of its big cone opening one end.The tapered sleeve of the utility model design adds certain security insurance measure, once bolt can be avoided to bear, shearing fracture, tapered sleeve are slipped or screw releases the accident for causing.
Description
Technical field
The utility model is related to the connection tapered sleeve of a kind of industrial big fan chassis assembly and motor shaft.
Background technology
Current existing motor shaft connection is generally axle key connection and bolt connection etc., for the feelings that motor shaft receives peripheral force
Shape, is typically not in the problem of connecting fault.But strong with vibration and hang on work-yard and by axial direction (vertical) power
Refitting put in the case of, with general connection method be difficult thoroughly solve connection safety issue.
Utility model content
The utility model proposes a kind of industrial big fan chassis assembly and the connection tapered sleeve of motor shaft, certain peace is added
Full coverage measure, once bolt can be avoided to bear, shearing fracture, tapered sleeve are slipped or screw releases the accident for causing.
What the technical solution of the utility model was realized in：
A kind of connection tapered sleeve of industrial big fan chassis assembly and motor shaft, including in the tapered sleeve cone portion of circular cone structure
Point, end face boss, breach, keyway and screw, the tapered sleeve conical section side wall is provided with the breach along longitudinal direction, the hole of breach opposite side
Inwall is provided with keyway, has screw on the end face boss of its big cone opening one end.
Preferably, the width of the breach is 1.5mm.
Preferably, the width of the keyway is 3mm.
What the utility model was produced has the beneficial effect that：The utility model alleviates weight, facilitates and install, enhance insurance work
With, improve the resultant effect of security etc..
Brief description of the drawings
In order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
The connection tapered sleeve of a kind of industrial big fan chassis assembly as shown in Figure 1 and motor shaft, including in circular cone structure
Tapered sleeve conical section 1, end face boss 2, breach 3, keyway 4 and screw 5, the side wall of the tapered sleeve conical section 1 are provided with along longitudinal direction
Breach 3, the hole inwall of the opposite side of breach 3 is provided with keyway 4, has screw 5 on the end face boss 2 of its big cone opening one end.
Preferably, the width of the breach 3 is 1.5mm.
Preferably, the width of the keyway 4 is 3mm.
During installation, axial cone set fits through the centre bore on chassis, and the axle key on the alignment motor shaft of keyway 4 is inserted in motor shaft,
The bottom of disk compression axis tapered sleeve is pressed, bolt is screwed into motor shaft through pressure disc centre hole along axle center screwed hole.Opened along longitudinal direction
Elongated breach 3 1.5mm wide, makes it be in disrupted configuration, has a bit with the tightness cooperation and circumference for keeping itself and chassis
Tension force.Size is more smaller than motor shaft before installing, by being expanded after extruding.The opposite side of tapered sleeve breach 3 is provided with vertical port keyway 4, its
There is symmetrical screwed hole on big cone opening end face, it is therefore an objective to do not allow it to have relative rotation with axle.Tapered sleeve can be by its conical surface, tapered sleeve breach
Formed huge tension force, extruding force and hold tightly on the inwall on chassis, key, keyway are snapped on axle.The lower end cone of motor shaft
Set is connected with chassis, and tapered sleeve is inserted in motor shaft through the chassis for coordinating, its keyway alignment axle key, and pressure disk pushes down chassis and tapered sleeve
Bottom, screw is screwed into motor shaft through pressure disk mesopore along axle center screwed hole, then with 6 screws are through chassis and press plectane circumference
Hole is fixed with 6 hole annulus of chassis end face.
Chassis and bluff piece are provided with perforate in the utility model, and bluff piece is provided with flabellum hole and is connected with flabellum, chassis, pawl
Part, flabellum constitute flabellum component and are connected with motor shaft.Axial cone set can form huge tension force, extruding force by its conical surface, breach
And held tightly on the hole inwall on chassis, axle is connected with tapered sleeve and transmit torque by key, keyway.Have in the utility model
Anti-run safety structure used cooperatively with tapered sleeve, moreover it is possible to effective early warning and prevent chassis and its connector from being fallen from motor shaft.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
