Abstract

The utility model relates to an automatic tight connection cover that expands of centering contains the outer lane that inner circle and cover circled including establishing, correspond the inclined plane that is provided with two sections parallels on the internal surface of outer lane and on the surface of inner circle, just outer lane and inner circle are through the screw connection of many settings between two sections inclined planes, the utility model discloses become single cone combined with with interior outer lane by two cone combined with, the outer lane can the automatic centering when locking in making to the axiality of interior outer lane has been guaranteed.

Description

A kind of expansion coupling sleeve of automatic centering

Technical field

The utility model relates to connection area, refers 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.

Model utility content

The utility model object is the expansion coupling sleeve providing a kind of automatic centering in order to overcome the deficiencies in the prior art, is coordinated by Internal and external cycle become single cone match from Double-conical-surface, makes 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 adopted in the utility model 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 utility model 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 described in the utility model, 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 solutions of the utility model are 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 described in the utility model;

Wherein: 1, outer ring; 2, inner ring; 3, screw.

Embodiment

Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.

Accompanying drawing 2 is the expansion coupling sleeve of automatic centering described in the utility model, 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.

Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technological scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope .
