Abstract
The utility model discloses a kind of retaining shaft couplings.It includes connecting tube and the spindle nose positioned at connecting tube both ends, the axle sleeve being provided at both ends with for being installed to spindle nose of connecting tube, the annular groove that its middle part extends to root in being provided on the connecting pin of spindle nose, the initiating terminal of annular groove is set as tilting ring face, tilting ring face is connected with one section of cylindroid, the end of annular groove is set as limited step, and elastic rubbery body is filled between annular groove and axle sleeve inner surface, snap ring is equipped at the limited step of spindle nose.With the above structure, elastic rubbery body generates coupling mechanism force using tilting ring face when there is spindle nose and axle sleeve relative displacement, prevent the possibility of relative movement, snap ring set in addition, which realizes, to be reliably connected, improve the reliability of connection, so as to ensure that service precision, the convenience of dismounting is also dexterously improved additionally by the structure design, improves replacement efficiency.
Description
Technical field
The utility model is related to a kind of shaft coupling, specifically a kind of retaining shaft coupling.
Background technology
Shaft coupling is for being attached a kind of device transmitted so as to fulfill torque to component, and existing shaft coupling is general
All include connecting tube, the connector mounted on connecting tube both ends, connector is fixedly mounted by connector sleeve and connecting tube, existing this
Structure is more common and application is also very extensive, although since its structure design is simple, can realize the reliable biography of power
Pass, it is well known that, in use, due in its operational process can by different load, so that spindle nose and
Opposite movement can be generated between connecting tube, so as to affect use reliability and precision.
Invention content
The technical problem to be solved in the present invention is to provide it is a kind of it is reasonable in design, precision is high, use reliability is good only
Move back shaft coupling.
In order to solve the above-mentioned technical problem, retaining shaft coupling of the invention, including connecting tube and positioned at connecting tube both ends
Spindle nose, the axle sleeve being provided at both ends with for being installed to spindle nose of connecting tube, in being provided on the connecting pin of spindle nose wherein
The annular groove that portion extends to root, the initiating terminal of annular groove are set as tilting ring face, and tilting ring face is connected with one section of cylindroid, ring
The end of slot is set as limited step, filled with elastic rubbery body between annular groove and axle sleeve inner surface, at the limited step of spindle nose
Snap ring is installed.
It is intersegmental away from the size of the spacing and the width phase of snap ring that one is provided between end face of shaft bush at the limited step
When.
The snap ring for two halves to opening structure, be fixedly mounted after snap ring pairing described in two halves by fastener.
The connecting tube is provided at both ends with flanged ends, the flanged ends connection of axle sleeve and connecting tube.
The angle of inclination in the tilting ring face is 30-45 degree.
The connecting tube is stainless steel tube.
After above-mentioned structure, due to its middle part extends to root in being provided on the connecting pin of spindle nose annular groove and
Snap ring is installed at the elastic rubbery body and the limited step of spindle nose filled between annular groove and axle sleeve inner surface, thus when there is axis
Elastic rubbery body generates coupling mechanism force using tilting ring face when head and axle sleeve relative displacement, prevents the possibility of relative movement, separately
The snap ring of outer setting, which realizes, to be reliably connected, and improves the reliability of connection, so as to ensure that service precision, additionally by the knot
Structure designs the convenience for also dexterously improving dismounting, improves replacement efficiency.
Description of the drawings
Fig. 1 is the structure diagram of retaining shaft coupling of the present invention.
Specific embodiment
With reference to the accompanying drawings and detailed description, the retaining shaft coupling of the present invention is described in further detail.
As shown in the figure, the retaining shaft coupling of the present invention, the spindle nose 2 including connecting tube 1 and positioned at connecting tube both ends, connection
The axle sleeve 3 being provided at both ends with for being installed to spindle nose of pipe 1, its middle part is to root in being provided on the connecting pin of spindle nose 2
The annular groove 4 of extension, the initiating terminal of annular groove 4 are set as tilting ring face 5, and tilting ring face 5 is connected with one section of cylindroid 6, annular groove 4
End be set as limited step 7, filled with elastic rubbery body 8 between annular groove 4 and axle sleeve inner surface, the limiting stand of the spindle nose
Snap ring 9 at rank is installed, it is intersegmental away from size and the snap ring 9 of the spacing to be provided with one at limited step 7 between end face of shaft bush
Width is suitable.
Further, described snap ring 9 is that two halves pass through fastener fixation peace to opening structure, after snap ring pairing described in two halves
Dress, connecting tube 1 are provided at both ends with flanged ends 10, and the flanged ends of axle sleeve and connecting tube connects, tilting ring face 5
Angle of inclination is 30-45 degree, and connecting tube 1 is stainless steel tube.
