A kind of shaft joint, including：Axle, axle sleeve, trapezoidal locking nut, axially position bolt and radial positioning bolt；It is described
Axle includes axle main body and spindle nose, and the axle sleeve is located at the outside of the axle main body, and the axle sleeve is matched somebody with somebody with the axle main body interference
Close, the trapezoidal locking nut is twisted and is located on the spindle nose, and the trapezoidal locking nut passes through the axially position bolt and institute
Axle sleeve connection is stated, the trapezoidal locking nut is connected by the radial positioning bolt with the spindle nose.
Preferably, the axially position bolt is arranged to multiple, and is uniformly distributed along the axial direction of the trapezoidal locking nut.
Preferably, the radial positioning bolt is arranged to multiple, and along the radially uniform distribution of the trapezoidal locking nut.
The beneficial effects of the utility model are：The shaft joint that the utility model embodiment provides, by using trapezoidal locking
Nut replaces common locking nut, and by the trapezoidal locking nut of axially position bolt connection and axle sleeve, passes through radial positioning
The trapezoidal locking nut of bolt connection and spindle nose so that axle sleeve, trapezoidal locking nut and axle are closely connected as an entirety, it is ensured that set
It is standby that locking nut loose phenomenon will not occur in operation process, and then ensure that the mating surface of axle sleeve and axle will not be damaged,
Enable shaft joint preferably passing power, moment of torsion, equipment normal operation.
Brief description of the drawings
Fig. 1 is the coupler structure schematic diagram that prior art provides；
Fig. 2 is coupler structure schematic diagram provided by the utility model.
In figure, the implication of each symbol is as follows：
1 axle main body, 2 axle sleeve bolts hole, 3 axle sleeves, 4 locking nuts, 5 spindle noses, 6 axially position bolts, 7 trapezoidal locking screws
Female, 8 radial positioning bolts.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing, to this reality
It is further elaborated with new.It should be appreciated that embodiment described herein is only explaining this practicality
It is new, it is not used to limit the utility model.
As shown in Fig. 2 the utility model embodiment provides a kind of shaft joint, including：Axle, axle sleeve 3, trapezoidal locking nut
7th, axially position bolt 6 and radial positioning bolt 8；The axle includes axle main body 1 and spindle nose 5, and axle sleeve 3 is located at the outer of axle main body 1
Side, trapezoidal locking nut 7 are twisted and are located on spindle nose 5, and trapezoidal locking nut 7 is connected by axially position bolt 6 with axle sleeve 3, trapezoidal
Locking nut 7 is connected by radial positioning bolt 8 with spindle nose 5.
In said structure, axle sleeve can use the modes such as interference fit, key and the conical surface to be connected with axle main body, and taper is generally
1：20 (can be adjusted according to the magnitude of interference).
This shaft joint can install fastener by the bolt hole set on axle sleeve with pairing shaft joint and be attached, and realize dynamic
Power, moment of torsion transmission.
In use, after axle sleeve being installed to the outside of axle main body, trapezoidal locking nut is screwed on spindle nose, locked
Axle main body and axle sleeve, in order that axle is connected more firm with axle sleeve, in the present embodiment, the locking nut used is trapezoidal lock
Tight nut, the longer end of trapezoidal locking nut contact with axle main body and axle sleeve, using axially position bolt by the longer end
Portion is attached with axle sleeve, so that axle sleeve and trapezoidal locking nut are integrally formed, meanwhile, using radial positioning bolt by ladder
The body of shape locking nut is attached with spindle nose, so that spindle nose and trapezoidal locking nut are integrally formed.
So in the present embodiment, by radial positioning bolt and axially position bolt, by axle sleeve, trapezoidal locking nut and
Axle is closely connected as an entirety, it is ensured that locking nut loose phenomenon will not occur in operation process for equipment, and then ensure
The mating surface of axle sleeve and axle will not be damaged so that shaft joint can preferably passing power, moment of torsion, equipment normal operation.
In the present embodiment, axially position bolt 6 is arranged to multiple, and is uniformly distributed along the axial direction of trapezoidal locking nut 6.
Using said structure, it can make it that the connection between axle sleeve and trapezoidal locking nut is more firm, in equipment operation
During, it is less prone to the loose phenomenon of trapezoidal locking nut.
In the present embodiment, radial positioning bolt 8 is arranged to multiple, and along the radially uniform distribution of trapezoidal locking nut 6.
Using said structure, it can make it that the connection between spindle nose and trapezoidal locking nut is more firm, in equipment operation
During, it is less prone to the loose phenomenon of trapezoidal locking nut.
By using above-mentioned technical proposal disclosed in the utility model, following beneficial effect has been obtained：The utility model
The shaft joint that embodiment provides, replaces common locking nut, and pass through axially position bolt by using trapezoidal locking nut
Trapezoidal locking nut and axle sleeve are connected, passes through the trapezoidal locking nut of radial positioning bolt connection and spindle nose so that axle sleeve, trapezoidal lock
Tight nut and axle are closely connected as an entirety, it is ensured that locking nut loose phenomenon will not occur in operation process for equipment, enter
And ensure that the mating surface of axle sleeve and axle will not be damaged so that shaft joint can preferably passing power, moment of torsion, equipment it is normal
Operation.
