Abstract
The invention relates to an automatic centering expansion joint sleeve comprising an inner ring and an outer ring for sleeving the inner ring, wherein two sections of parallel slopes are correspondingly arranged on the inner surface of the outer ring and the outer surface of the inner ring; and the outer ring is connected with the inner ring through a plurality of screws arranged between the two sections of slopes. According to the automatic centering expansion joint sleeve, the inner ring is matched with the outer ring through a single conical surface instead of double conical surfaces, so that the inner ring and the outer ring can be automatically centered when being locked, and furthermore the coaxiality of the inner ring and the outer ring is ensured.
Description
Technical field
The present invention relates to connection area, refer in particular to a kind of expansion coupling sleeve of automatic centering.
Background technique
Expansion coupling sleeve is a kind of detachable apparatus of connection rotating shaft and drive flange or drive wheel, there is easy accessibility, to the advantage such as union piece required precision is low, the conical surface of outer ring and inner ring is extruded by axial direction, outer ring is swollen, inner ring and then reduces and produces interference fit with link, thus can transmitting torque and axial force, but existing expansion sleeve as shown in Figure 1, because Internal and external cycle adopts Double-conical-surface to coordinate, when locking, be difficult to guarantee two uniform force and deformations of end ring even, therefore the coaxality of Internal and external cycle is not easily ensured, for this reason, we have developed a kind of expansion coupling sleeve of automatic centering, Internal and external cycle is coordinated from Double-conical-surface and becomes single cone match, make Internal and external cycle energy automatic centering when locking, thus ensure that the coaxality of Internal and external cycle.
Summary of the invention
The present invention seeks to the expansion coupling sleeve that a kind of automatic centering is provided to overcome the deficiencies in the prior art, Internal and external cycle being coordinated from Double-conical-surface and becomes single cone match, make Internal and external cycle energy automatic centering when locking, thus ensure that the coaxality of Internal and external cycle.
For achieving the above object, the technical solution used in the present invention is: a kind of expansion coupling sleeve of automatic centering, comprises inner ring and is set in the outer ring on inner ring; The internal surface of described outer ring is provided with two sections of parallel inclined-planes with corresponding on the outer surface of inner ring, and described outer ring and inner ring are connected by the screw that many are arranged between two sections of inclined-planes.
Preferably, the tilt angle on two sections of described inclined-planes is 5-10 degree.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Internal and external cycle is become single cone match from Double-conical-surface cooperation by the expansion coupling sleeve of automatic centering of the present invention, makes Internal and external cycle energy automatic centering when locking, thus ensure that the coaxality of Internal and external cycle.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural drawing of prior art;
Accompanying drawing 2 is the structural drawing of the expansion coupling sleeve of automatic centering of the present invention;
Wherein: 1, outer ring; 2, inner ring; 3, screw.
Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 2 is the expansion coupling sleeve of automatic centering of the present invention, the outer ring 1 comprising inner ring 2 and be set on inner ring 2; The internal surface of described outer ring 1 is provided with two sections of parallel inclined-planes with corresponding on the outer surface of inner ring 2, and the tilt angle on two sections of described inclined-planes is 5-10 degree; Described outer ring 1 and inner ring 2 are connected by the screw 3 that many are arranged between two sections of inclined-planes, by rotating screw 3, outer ring 1 and inner ring 2 are moved along inclined-plane, outer ring is swollen, inner ring reduces and produce interference fit transferring power with link.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Internal and external cycle is become single cone match from Double-conical-surface cooperation by the expansion coupling sleeve of automatic centering of the present invention, makes Internal and external cycle energy automatic centering when locking, thus ensure that the coaxality of Internal and external cycle.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technological scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
