The placing chamber wall portion of the shaft housing connector uniformly has three guide grooves, and push rod is both provided with each guide groove;
The push rod is inner to be less than the 1/2 of spacing groove depth for wedge shape, wedge shape height;
The push rod is inner to be and the conical adaptable V-arrangement of push rod for cone, stopper slot;
Position on the shaft housing connector excircle below guide groove is provided with toroidal cavity, and fluted disc is placed in annulus In connected in star;
Annular knurl is provided with 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 push rod for being similar to worm structure, rotation fluted disc coordinate driving push rod to extend inwardly into shaft end limit along guide groove with push rod Position groove in provide axial limiting, further rotate fluted disc driving push rod hold out against shaft end provide radially it is spacing, axle can be provided simultaneously Simple in construction to spacing with radially spacing, installation operation is convenient, and connection is reliable.

Embodiment
As illustrated, a kind of shaft coupling with axial limiting, including cylinder-shaped sleeve connector 1, the one end of shaft housing connector 1 With the placing chamber 4 for being capable 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 the wall portion of placing chamber 4 of axis connection, and being provided with guide groove can be along guide groove outwardly or inwardly The push rod 2 of slip, helical tooth is provided with the outer circumference surface of push rod 2 so that push rod 2 forms the structure for being similar to worm screw;Axle sleeve connects Position on the excircle of fitting 1 below guide groove is provided with fluted disc 3, is provided with what is coordinated with push rod helical tooth on fluted disc 3 Spiral alveolar 6, can be coordinated when fluted disc 3 rotates by spiral alveolar 6 and push rod 2 driving push rod 2 along guide groove outwardly or inwardly Slide;Shaft end is provided with stopper slot with the relevant position outer surface of push rod 2, and the inner of push rod 2 can extend into stopper slot and provide axially It is spacing, it is easy to operate.
The wall portion of placing chamber 4 of shaft housing connector 1 uniformly has three guide grooves, is both provided with push rod 2 in each guide groove, and three Individual push rod 2 uniformly holds out against shaft end from three different directions simultaneously and provides axial limiting and radially spacing, spacing reliable, bonding strength It is high.
The shaft coupling with axial limiting of the present invention, the scheme of embodiment one use cylindrical push rod 2, the excircle of push rod 2 One section of helical tooth is provided with face so that push rod 2 forms the structure for being similar to worm screw, and fluted disc 3 passes through spiral alveolar 6 and push rod 2 Coordinate driving push rod 2 to be slided along guide groove, can be rotated when the stress of push rod 2 is big, can not also rotate, operate when sliding smooth Flexibly.
The shaft coupling with axial limiting of the present invention, the scheme of embodiment two set push rod 2 inner for wedge shape, wedge shape height Less than the 1/2 of spacing groove depth;The wedge shape of push rod 2 coordinates with stopper slot to be more convenient, and shaft end does not have to accurate capturing position when connecting It can connect, it is easy for installation by tapered end and stopper slot adjust automatically aligned fit
The shaft coupling with axial limiting of the present invention, the scheme of embodiment three set push rod inner for cone, stopper slot be with The adaptable V-arrangement of push rod cone;Conical end is more easy to be connected with stopper slot, and positioning is more reliable, and fit clearance almost may be used To ignore.
Position on the excircle of shaft housing connector 1 below guide groove is provided with toroidal cavity, and fluted disc 3 is placed in circle In annular groove, the width of fluted disc 3 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.
Annular knurl is provided with the excircle of fluted disc 3, can be rotated by knurling structure in order to sliding tooth disk 3.
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 push rod for being similar to worm structure, rotation fluted disc coordinate driving push rod to extend inwardly into shaft end limit along guide groove with push rod Position groove in provide axial limiting, further rotate fluted disc driving push rod hold out against shaft end provide radially it is spacing, axle can be provided simultaneously Simple in construction to spacing with radially spacing, installation operation is convenient, and connection is reliable.
