The shaft coupling with axial limiting of the present invention, including cylinder-shaped sleeve connector, shaft housing connector one end have energy The placing chamber of enough fixed connection shafts, the other end have the pin and slot for the connection that can work in coordination;It is characterized in that:Axle sleeve connects The placing chamber wall portion of fitting and axis connection has been disposed radially guide groove, be equipped in guide groove can along guide groove inwardly or to The mandril of outer sliding is provided with helical tooth on mandril outer circumference surface so that mandril constitutes the structure for being similar to worm screw;Axle sleeve connects It is located at the position below guide groove on part excircle and is provided with fluted disc, the helical tooth coordinated with mandril helical tooth is provided on fluted disc Slot can coordinate driving mandril outwardly or inwardly to be slided along guide groove when fluted disc rotates by spiral alveolar and mandril;Shaft end with 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 It can connect, it is easy for installation by tapered end and limiting slot adjust automatically aligned fit
The scheme setting mandril inner end of the shaft coupling with axial limiting of the present invention, embodiment three is cone, limiting slot For the V-arrangement being adapted with mandril cone;Conical end is more easy to connect with limiting slot, and positioning is more reliable, and fit clearance is several It can be ignored.
It is located at the position below guide groove on 1 excircle of shaft housing connector and is provided with toroidal cavity, fluted disc 3 is placed in circle In annular groove, 3 width of fluted disc is less than the 1/2 of placing chamber wall thickness, and fluted disc 3 occupies little space, it is ensured that the support of shaft housing connector 1 Intensity.
It is provided with annular knurl on 3 excircle of fluted disc, can be rotated in order to sliding tooth disk 3 by knurling structure.
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.
