Axle and the attachment structure of output shaft, include the instruction axle being sheathed in eccentric drive shaft and the output shaft linked with instruction axle,
The axial one end for indicating axle is the indication end being connected with instrument board, and the other end is linkage end, it is characterised in that：The output shaft court
To mounting groove is offered on the end face for indicating axle linkage end, the linkage end of the instruction axle is extended in mounting groove, and indicates axle
Linkage end and output shaft between connected by coupling assembly, the eccentric drive shaft is relative to towards output shaft axial direction one end
Positioning bearing is arranged with the outer peripheral face of the other end.
Using above-mentioned technical proposal, the linkage end of axle is indicated directly to implement to be connected with output shaft by coupling assembly, when inclined
When heart power transmission shaft implements linkage with output shaft, axle is indicated to be rotated with output shaft by coupling assembly thereon, so that can be accurate
The angle at output shaft is embodied, and implements to show by instrument board, and so setting makes instruction axle concentric with output shaft
Degree is guaranteed, so that the data of display are more accurate；Eccentric drive shaft relative to towards output shaft axial direction one end it is another
The setting that bearing is positioned on the outer peripheral face at end is then for the ease of other the part realities inside eccentric drive shaft and YE
Positioning is applied, so that concentricity when keeping it to install.
The utility model is further arranged to：Coupling assembly includes and indicates the axle fixed driving pad in linkage end and be located at
Driver blade on driving pad, is provided with the mounting hole for being adapted to driver blade and supplying driver blade grafting in the mounting groove of the output shaft.
Using above-mentioned technical proposal, such setting structure is simple, easy to assembly.
The utility model is further set to：Driving pad is connected with axle linkage end socket is indicated, the axial direction two of driving pad
It is respectively equipped with flexibly positioned back-up ring at end, described driver blade is with driving pad to be integrally machined shaping and perpendicular with driving pad turn over
The plates of folding.
Using above-mentioned technical proposal, flexibly positioned back-up ring can will be sheathed on the axial direction and circumference reality for indicating the driving pad on axle
Positioning is applied, and linkage is implemented by driver blade thereon and output shaft, when output shaft rotates, driver blade is rotated with it, transmission
Sector-meeting drives driving pad and the instruction axle rotation being connected with driving pad, and such setting structure is compact, is easy to assembling.
The utility model is further described below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model embodiment is installed in YE；
Fig. 2 is the schematic perspective view for indicating axle to be connected with driving pad in the utility model embodiment；
Fig. 3 is the schematic perspective view of driving pad in the utility model embodiment；
