Deviation.
To be easy to implement being detachably connected for axle sleeve and dynamic rotation axis and load rotary shaft, further, the axle sleeve
Radially it is arranged jagged, the outer peripheral surface of axle sleeve is run through in one end of notch, and the other end of notch is connected to the port；
The locking through-hole being connected to notch is additionally provided on axle sleeve, the outer peripheral surface of axle sleeve is run through at the both ends for locking through-hole.
The utility model runs through the bolt for locking through-hole and the nut with bolt thread cooperation in application, being also equipped with,
In this way, then dynamic rotation axis and load rotary shaft can be locked in port.
For the stability for improving two axle sleeves and dynamic rotation axis and load rotation axis connection, the inner wall of the axle sleeve is along it
Axially it is provided with the locking slot of notch described in face.
In the utility model, the setting of locking slot can reduce the rigidity of axle sleeve, in this way, can deform convenient for axle sleeve with reality
The now locking work between dynamic rotation axis and axle sleeve or between load rotary shaft and axle sleeve.
The utility model has the following beneficial effects:
1, it since groove is in the small and big inner cavity setting that is open, thus after in convex portion merging groove, can effectively keep away
Exempt from two axle sleeves to be separated with connector in the axial direction.
2, protrusion can be slidably matched with groove, so, it is ensured that the shaft coupling can allow dynamic rotation axis and load rotation
Axis deviation in the radial direction.
3, the setting of the arc surface of groove groove bottom and roll segment outer peripheral surface is, it can be achieved that protrusion and the rolling of groove cooperate, such as
This, can steadily adjust the angle of two axle sleeves, and then be suitable for dynamic rotation axis and load deviation of the rotary shaft in angle.
4, the setting of connector port can assist axle sleeve port to adapt to dynamic rotation axis and load rotary shaft in the axial direction
Deviation.
5, by the setting of locking slot, the rigidity of axle sleeve can be reduced, in turn, is deformed convenient for axle sleeve to realize that power revolves
Locking work between shaft and axle sleeve or between load rotary shaft and axle sleeve.
