Mandril corresponding position outer surface is provided with limiting slot, and mandril inner end, which can extend into, provides axial limiting in limiting slot;
The placing chamber wall portion of the shaft housing connector is both provided with mandril uniformly there are three guide groove in each guide groove;
The mandril inner end is wedge shape, and wedge shape height is less than the 1/2 of limit groove depth;
The mandril inner end is cone, and limiting slot is the V-arrangement being adapted with mandril cone;
It is located at the position below guide groove on the shaft housing connector excircle and is provided with toroidal cavity, fluted disc is placed in
In toroidal cavity;
It is provided with annular knurl on the fluted disc excircle.
The shaft coupling with axial limiting of the present invention, in the placing chamber wall portion mounting circular ring of shaft housing connector fixed connection shaft
Shape fluted disc and the mandril for being similar to worm structure, rotation fluted disc extend inwardly into shaft end along guide groove with mandril cooperation driving mandril and limit
Axial limiting is provided in the slot of position, fluted disc driving mandril is further rotated and offer radial limit in shaft end is provided, axis can be provided simultaneously
It is limited to limit with radial, simple in structure, installation operation is convenient, and connection is reliable.

Specific implementation mode
As shown, a kind of shaft coupling with axial limiting, including cylinder-shaped sleeve connector 1,1 one end of shaft housing connector
With the placing chamber 4 for capableing of fixed connection shaft, the other end has the pin and slot for the connection that can work in coordination;Shaft housing connector
1 has been disposed radially guide groove with 4 wall portion of placing chamber of axis connection, and being equipped in guide groove can be along guide groove outwardly or inwardly
The mandril 2 of sliding is provided with helical tooth on 2 outer circumference surface of mandril so that mandril 2 constitutes the structure for being similar to worm screw;Axle sleeve connects
It is located at the position below guide groove on 1 excircle of fitting and is provided with fluted disc 3, is provided on fluted disc 3 and coordinates with mandril helical tooth
Spiral alveolar 6, fluted disc 3 rotate when can by spiral alveolar 6 and mandril 2 cooperation driving mandril 2 along guide groove outwardly or inwardly
Sliding;Shaft end is provided with limiting slot with 2 corresponding position outer surface of mandril, and 2 inner end of mandril can extend into limiting slot and provide axially
Limit, it is easy to operate.
4 wall portion of placing chamber of shaft housing connector 1 is both provided with mandril 2 uniformly there are three guide groove in each guide groove, and three
A mandril 2 uniformly holds out against shaft end from three different directions simultaneously and provides axial limiting and radial limit, and limit is reliable, bonding strength
It is high.
The shaft coupling with axial limiting of the present invention, the scheme of embodiment one is using cylindrical mandril 2,2 excircle of mandril
One section of helical tooth is provided on face so that mandril 2 constitutes the structure for being similar to worm screw, and fluted disc 3 passes through spiral alveolar 6 and mandril 2
Cooperation driving mandril 2 is slided along guide groove, can be rotated when 2 stress of mandril is big, can not also be rotated, be operated when sliding smooth
Flexibly.
2 inner end of scheme setting mandril of the shaft coupling with axial limiting of the present invention, embodiment two is wedge shape, wedge shape height
Less than the 1/2 of limit groove depth;The wedge shape of mandril 2 and limiting slot cooperation are more convenient, and accurate capturing position is not had to when shaft end connects
