When accessory works, output shaft drives the rotation of sliding tooth wheel so that driving gear and pivoting support engaged transmission, from
And accessory is driven to act.However, when driving gear and pivoting support engaged transmission, list that driving gear is applied by pivoting support
Xiang Li, and larger active force is generated to the side of output shaft close to pivoting support, other portions of this force ratio output shaft
The active force bigger that position is subject to, moreover, the free end end of output shaft does not install any part in engineering machine accessory, it is long and long
It, is easy to make the free end of output shaft to make output shaft distortion to the direction offset far from pivoting support, so as to cause accessory
Corresponding damage of components, that is, the flange spiral shell on the motor flange on motor broken screw, engineering machine accessory on the end cap of motor
Silk loosens, motor flange is broken and/or the Upper wear of driving gear engagement place is serious, and in turn resulting in engineering machine accessory can not make
With.
Utility model content
The purpose of this utility model is to provide a kind of revolution driving structure of engineering machine accessory, can be effectively prevented defeated
Go out axle offset, to improve the service life of engineering machine accessory
In order to achieve the above objectives, the solution of the utility model is：
A kind of revolution driving structure of engineering machine accessory, includes the motor with output shaft, drive gear and with the drive
The pivoting support that moving gear is meshed, the driving geared sleeve are set to outside the output shaft, and the motor is mounted on engineering machine category
On the shell of tool, the free end of the output shaft passes through the shell and in the shell, the free end of the output shaft
End set is collar, and pedestal is installed on the shell, corresponds on the pedestal at the output shaft and offers installation
Groove, the installation groove is interior to be embedded with axle sleeve, and the collar is sheathed in the axle sleeve.
The shell, which corresponds at the collar, offers opening, and the pedestal is installed in the opening.
A kind of revolution driving structure of engineering machine accessory, includes the motor with output shaft, drive gear and with the drive
The pivoting support that moving gear is meshed, the motor are mounted on the shell of engineering machine accessory, and the free end of the output shaft is worn
It crosses the shell and in the shell, the free end end of the output shaft is fixedly connected with transmission shaft, the sliding tooth
Wheel is sheathed on outside the transmission shaft, and the free end end set of the transmission shaft is collar, and pedestal is installed on the shell,
Correspond at the transmission shaft on the pedestal and offer installation groove, axle sleeve, the axle journal are embedded in the installation groove
Portion is sheathed in the axle sleeve.
The shell, which corresponds at the collar, offers opening, and the pedestal is installed in the opening.
With the above structure, the utility model has the advantages that：Coordinated by the connection of axle sleeve and collar,
So that collar is limited in axle sleeve and can not move radially, in this way, it is therefore prevented that the free end of output shaft is because close to revolution
The stress of the side of bearing is excessive and the free end of output shaft is made to be deviated towards the direction far from pivoting support, so as to avoid motor
On broken screw, the loosened screw on motor flange, the Upper wear of the engagement place of the fracture of motor flange and/or driving gear
Seriously, and then the service life of engineering machine accessory is improved.

Specific implementation mode
In order to which the technical solution of the utility model is explained further, below by specific embodiment come to the utility model into
Row elaborates.
A kind of revolution driving structure of engineering machine accessory of the utility model is made on the basis of common engineering machine accessory
The improvement gone out.
As shown in Figs. 1-2, this revolution driving structure includes motor 2, driving gear 4, pivoting support 5 with output shaft 3
With pedestal 6, motor 2 is installed together in the usual way with a motor flange 21, and motor flange 21 is fixed by flange screw 211
At the lateral wall of the shell 1 of engineering machine accessory；The free end of output shaft 3 passes through shell 1, and stretches into so far shell 1
Inside, driving gear 4 are keyed with output shaft 3, that is, gear 3 is driven to offer key connection hole, and driving gear 3 is keyed by this
Hole is closely sheathed on outside the free end of output shaft 3, and gear 4 is driven to be intermeshed with pivoting support 5, is driven gear 4 and is returned
Turn bearing 5 to be in shell 1.
The free end end set of output shaft 3 is collar 31, and pedestal 6 is fixedly installed on shell 1, specifically, shell
Body 1, which corresponds at collar 31, offers opening, and pedestal 6 is flush-mounted in this opening in the usual way, and is offered on pedestal 6
Installation groove, this installation groove is corresponding with collar 31, and axle sleeve 7 is embedded in this installation groove, and collar 31 is sheathed on this
In axle sleeve 7, this axle sleeve 7 plays the role of supporting output shaft 3 and limits the movement of collar 31.Wherein, installation groove, axle sleeve 7
It is on same axis with collar 31.
When engineering machine accessory works, i.e., motor 2 starts, and the output shaft 3 on motor 2 rotates, and output shaft 3 drives sliding tooth
4 rotation of wheel so that 5 engaged transmission of driving gear 4 and pivoting support, during output shaft 3 rotates, output shaft 3 close to
The side of pivoting support 5 is easy compared to other position stress biggers of output shaft 3 so that the free end of output shaft 3 is to separate
The direction of pivoting support 5 deviates, at this point, due to the effect of axle sleeve 7 so that collar 31 is restricted to can not in this axle sleeve 7
Offset, to make output shaft 3 not deviated towards any one side, in such manner, it is possible to which being effectively prevented from causes because of the offset of output shaft
The loosened screw on the motor flange on broken screw, engineering machine accessory, the fracture of motor flange on the end cap of motor and driving
The Upper wear of 4 engagement place of gear is serious, to improve the service life of this engineering machine accessory.
As another preferred embodiment, the output shaft 3 of motor is fixedly connected with transmission shaft, this transmission shaft is arranged with axle sleeve above-mentioned
Cooperation, this axle sleeve assemble in the manner aforesaid.
The foregoing is merely the preferred embodiment of the present embodiment, all equalizations done with the utility model claims range
Variation and modification, should all belong to the right of the utility model.
