Description

Packing ring external member and hole axle be the access node structure altogether

[technical field]

The utility model relates to a kind of packing ring external member that is connected that is used to protect between a part and the through hole, can be applicable to multiple machine applications field, relates to a kind of hole axle that uses this packing ring external member access node structure altogether simultaneously.

[technical background]

Packing ring is widely used in mechanical field; it is sheathed between axostylus axostyle and the through hole; play the effect that is connected between protection axle and the through hole---be used to guarantee being rigidly connected between axostylus axostyle and the through hole on the one hand; guarantee that on the other hand the rigidity active force between axostylus axostyle and the through hole is cushioned, reach and cause the effect of coupling hardness with softness.

Traditional simple and easy packing ring adopts colloidal materials to be made, be post (tube) shape, its outer cylinder does not generally have special processing and is smooth relatively, if when placing this gasket sleeve in the through hole, dislocation easily causes axostylus axostyle to get loose easily and eccentric situation occurs, therefore, need carry out pinpoint occasion to two axostylus axostyles by two through holes at some, just cause the accurate location of two axostylus axostyles to be difficult to guarantee easily.

Typically, for having the situation of the bright dress hinge of two axostylus axostyles in perforate on glass and arrangement, because the physical error that is difficult to avoid during the glass perforate, itself can cause departing from of position, hole and make two axostylus axostyles be difficult to accurately keep relative position relation, in this case, originally can be aided with adjusting by traditional packing ring, but because traditional packing ring material is even, although can by axostylus axostyle towards packing ring a certain radially oppress packing ring " is submitted " thus guarantee accurate position relation between two axostylus axostyles, but long-term compressing can make gasket deforms, make the glass unbalance stress, in the course of time, influence glass, assembling effect of packing ring even bright dress hinge (as dislocation occurring) and working life.Therefore, traditional packing ring is difficult to guarantee that the accurate installation of axostylus axostyle and through hole concerns.

Another kind of situation is that traditional packing ring shows with through hole basic with the footpath owing to being cylindricality, come off in order to guarantee that packing ring is unlikely, by pad outside the axostylus axostyle both sides install additional or similar parts, but keep away of the influence of unavoidable axostylus axostyle all the time to packing ring, promptly be in the process that axostylus axostyle is attacked towards through hole, frictional force between axostylus axostyle and the packing ring can drive packing ring and attack forward, so just make packing ring often by band from the tram of through hole, cause between axostylus axostyle, packing ring and the through hole coincide very not compact.A kind of traditional settling mode is that gasket sleeve is made taper, so that make packing ring attack tighter and tighter, in this case, because packing ring can only be forced tightly towards its end of attacking, and is oppositely then inoperative, and axostylus axostyle needs bidirectional modulation sometimes, therefore, this improvement is also not all roses.

Another situation is that packing ring is when being attacked compressing, when particularly after it is installed, being heated, expand or during the situation of other deformation, level of compression in its periphery and the through hole between week is too strong, cause the through hole radial force big suddenly, explosion appears in crisp material for glass and so on easily, influences product working life.

To sum up all, traditional various packing rings exist many not enough, are necessary to make improvements to improve the application of packing ring in being connected of axostylus axostyle and through hole.
