The utility model discloses a kind of antifriction eccentric shaft of sander, it is included by d-axis portion, radially enlarged portion, boss portion, left hand projection portion and the right side lug boss being sequentially connected with from top to bottom, mutually assembled with the upper bearing (metal) in upper lid on the top in d-axis portion, mutually assembled with rotor bottom, and the bottom surface top pressure of the rotor is on the upper surface in radially enlarged portion, radially enlarged portion is mutually assembled with the lower bearing in lower cover, and the height of the upper surface in the radially enlarged portion is equal to or slightly higher than the upper surface of lower cover；The utility model smart structural design, radially enlarged portion is rationally equipped with, the rotor that can be pointed in d-axis portion is supported, and then lift the stability of assembling, fitting tight, the swing possibility of good operating stability, effectively reduction rotor, so as to allow rotor to produce friction not between lower cover, the life-span of rotor and lower cover is increased, also accordingly extends the service life of sander, overall structure is simple in addition, it is easily achieved, beneficial to wide popularization and application.
Description
Technical field
It the utility model is related to sander technical field, and in particular to a kind of sander for applying in sander is antifriction
Eccentric shaft.
Background technology
Sander is applied to iron plate, timber, plastics, and tire industry surface grinding, ship, automobile, grinding tool, aircraft industry are finely thrown
Light, burr removing, derusting, go the operations such as paint.
Modern society generally uses sander, and the sander sold on the market is varied, and it each has different set
Meter theory, make every effort to the requirement that can reach different user.But although these sanders can substantially meet requirement, its
Motor configuration in eccentric shaft structure design it is all not very ingenious, the assembling of rotor and eccentric shaft is not close, easily occurs rocking existing
As producing friction between rotor and lower cover so as to allow, greatly shortening the life-span of rotor and hd, also accordingly reduce sander
Service life.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, there is provided a kind of smart structural design, reasonable, fitting tight,
The antifriction eccentric shaft of sander of good operating stability.
To achieve the above object, technical scheme provided by the utility model is：
A kind of antifriction eccentric shaft of sander, it is included by the d-axis portion, radially enlarged being sequentially connected with from top to bottom
Portion, boss portion, left hand projection portion and right side lug boss, the right side lug boss and the lap position in left hand projection portion inwardly concave shape
Into an assembly cavity, the central axis of the assembly cavity and the central shaft in d-axis portion on the same axis, the d-axis portion, do not increase radially
Big portion and the concentric setting of boss portion；The diameter in the d-axis portion, radially enlarged portion and boss portion increases successively；The d-axis portion
Top mutually assembled with the upper bearing (metal) in the upper lid, bottom is mutually assembled with rotor, and the bottom surface top pressure of the rotor is in radial direction
On the upper surface in increase portion, radially enlarged portion is mutually assembled with the lower bearing in lower cover, and the upper end in the radially enlarged portion
The height in face is equal to or slightly higher than the upper surface of lower cover；The upper surface top pressure of boss portion is on lower bearing.
As a kind of improvement of the present utility model, small axle center is provided with by axle center bearing in the assembly cavity.
The beneficial effects of the utility model are：The utility model smart structural design, rationally it is equipped with radially enlarged portion, energy
The rotor being pointed in d-axis portion is supported, and then lifts the stability of assembling, fitting tight, good operating stability, effectively
The swing possibility of rotor is reduced, so as to allow rotor to produce friction not between lower cover, increases the life-span of rotor and lower cover,
The corresponding service life for extending sander, overall structure is simple in addition, it is easy to accomplish, beneficial to wide popularization and application.
Below in conjunction with the accompanying drawings with embodiment, the utility model is further illustrated.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model.
Fig. 2 is the structural representation that the utility model is arranged on sander.
Fig. 3 is the structure enlargement diagram of local A in Fig. 2.
Embodiment
Embodiment, referring to Fig. 1, Fig. 2 and Fig. 3, a kind of antifriction eccentric shaft of sander of the present embodiment offer, it includes pressing
D-axis portion 1, radially enlarged portion 2, boss portion 3, left hand projection portion 4 and the right side lug boss 5 being sequentially connected with from top to bottom, should
Right side lug boss 5 and the lap position in left hand projection portion 4 inwardly concave to form an assembly cavity 51, the central axis of the assembly cavity 51
With the central shaft in d-axis portion 1 not on the same axis, 3 concentric setting of the d-axis portion 1, radially enlarged portion 2 and boss portion；Institute
The diameter for stating d-axis portion 1, radially enlarged portion 2 and boss portion 3 increases successively；The top in the d-axis portion 1 is with being arranged in upper lid 6
The assembling of the phase of upper bearing (metal) 7, bottom and the phase of rotor 8 assembling, and the bottom surface top pressure of the rotor 8 is on the upper surface in radially enlarged portion 2,
Radially enlarged portion 2 is assembled with the phase of lower bearing 10 in lower cover 9, and the height of the upper surface in the radially enlarged portion 2 is equal to
Or the slightly above upper surface of lower cover 9；Preferably, the height of the upper surface in radially enlarged portion 2 is slightly above the upper surface of lower cover 9, it is high
In being preferably dimensioned to be 0.03mm.The upper surface top pressure of boss portion 3 is on lower bearing 10.
Small axle center 12 is provided with by axle center bearing 11 in the assembly cavity 51, mill can be installed by small axle center 12
Tool, brings convenience to installing and using.
During work, due to being rationally equipped with radially enlarged portion 2, the rotor 8 that can be pointed in d-axis portion 1 is supported, and is entered
And the stability of assembling is lifted, fitting tight, good operating stability effectively reduces the swing possibility of rotor 8, so as to allow rotor
8 produce friction not between lower cover 9, increase the life-span of rotor 8 and lower cover 9, also accordingly extend the service life of sander.
The announcement and teaching of book according to the above description, the utility model those skilled in the art can also be to above-mentioned realities
The mode of applying is changed and changed.Therefore, the utility model is not limited to embodiment disclosed and described above, right
Some modifications and changes of the present utility model should also be as falling into scope of the claims of the present utility model.In addition, to the greatest extent
Some specific terms have been used in pipe this specification, but these terms are merely for convenience of description, not to the utility model
Form any restrictions.As described in the utility model above-described embodiment, using other obtained from same or similar structure
The rotating shaft of structure, in scope of protection of the utility model.
