Description
Technical field
It the utility model is related to a kind of eccentrically weighted shaft.
Background technology
At present, the use of eccentrically weighted shaft is more and more extensive, especially in terms of such as reductor, conveyer belt, in order to special
Needs, it is necessary to add eccentrically weighted shaft to reach required technique effect, but current eccentrically weighted shaft there is dismounting not
Easily, the problem of and rigidity is not high.
Utility model content
To solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of eccentrically weighted shaft, can solve the problem that mesh
Pre-eccentric rotating shaft is not easy to change, and the problem of durability degree difference.
In order to realize above-mentioned target, the utility model adopts the following technical scheme that：
A kind of eccentrically weighted shaft, it is characterized in that, including body, eccentric orfice, adjustment hole and centre bore；The body is arranged to round
Cylinder；The eccentric orfice, adjustment hole and centre bore are arranged on body；The centre bore is arranged on the non-central position of body
Put；The top and bottom of the eccentric orfice up/down perforation body；The section of the eccentric orfice uses arc；Circle corresponding to the eccentric orfice
The heart is located at the circle centre position of centre bore；The adjustment hole is axisymmetricly distributed with centre bore, and symmetry axis is pair in eccentric orfice section
Claim axle.
Further, the adjustment hole could be arranged to penetrate the through hole of body top and bottom with centre bore, can also set
For non-through hole.
Further, when the adjustment hole and centre bore are arranged to non-through hole, the bottom week of adjustment hole and centre bore
While it is provided with fillet.
Further, the adjustment hole is located at the same face or different faces of body with centre bore.
Further, when the adjustment hole and centre bore be located at body different faces, adjustment hole and centre bore not face, tune
The central shaft of knothole and the central shaft of centre bore stagger.
Further, the section of the adjustment hole is arranged to regular hexagon.
The beneficial effect that the utility model is reached：The present apparatus can be applied to different production requirements, according to different
Production environment changes selection, is conveniently replaceable, and more rigid.
Brief description of the drawings
Fig. 1 is the cross-sectional view of one embodiment of the present apparatus；
Fig. 2 is Fig. 1 positive structure schematic；
Fig. 3 is Fig. 1 structure schematic diagram；
Fig. 4 is the cross-sectional view of another embodiment of the present apparatus；
Fig. 5 is the cross-sectional view of Fig. 4 another angle.
The implication of reference in figure：
1- bodies, 2- eccentric orfices, 3- adjustment holes, 4- centre bores.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating this
The technical scheme of utility model, and the scope of protection of the utility model can not be limited with this.
The present embodiment is combined the environment being applicable and illustrated by two cases.
Embodiment as shown in Figure 1, in terms of being mainly used in gear reduction unit, because The gear deceleration is by size gear train
Realized with the structures of the different numbers of teeth, therefore to stagger and avoid interference with, so output shaft uses eccentric shaft structure.It is eccentric in Fig. 1
Axle and output axis connection, centre bore are used to be connected with equipment.
Embodiment as shown in Figure 2, in terms of being mainly used in conveyer belt, it is sometimes necessary to appropriate tensioning is carried out to conveyer belt
Operation, complete to be similar to the same operation of vibratory sieve, at this time just completed by eccentric shaft, in connection member is passed through
Heart hole completes to connect.
It is worthy of careful study very much in the structure of the present apparatus, in terms of sectional view, centre bore, eccentric orfice and adjustment hole are into axial symmetry
, and the symmetry axis of three is identical, so allows for the present apparatus and is carrying out in use, can keep stable in rotary course
Property, it is assumed that there is certain deviation corresponding position in the position in one of hole and figure, then in the rotary course of the present apparatus,
Extra outside centrifugal force will be produced, so as to which bigger pressure can be produced to the connecting portion in attachment means, is influenceed resistance to
Degree long.
In addition, centre bore and adjustment hole are located at different faces and when are non-through hole, in order to further improve just
Property and durability degree, both positions are mutually staggered, if complete face, part between the two can be more fragile, especially
It is the durability degree that the present apparatus is greatly influenceed when carrying out rotary work.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and deformation can also be made, these change
Enter and deform and also should be regarded as the scope of protection of the utility model.
