Abstract
The invention discloses a gasket comprising a ring-shaped body. The gasket is characterized in that a protrusion loop is integrally arranged on at least one end face of the ring-shaped body. The gasket has the advantages of good sealing performance, can prevent oil leakage and is easy to tighten up.
Description
Technical field
The present invention relates to a kind of packing ring, relate in particular to a kind of sealing packing ring preferably.
Background technique
Packing ring is a kind of thin metal gasket be placed between nut or screw head and connected piece.Existing packing ring is generally flat metal ring, with bolt, be used in conjunction with, because bolt is cast member, the surface that bolt contacts with packing ring is often smooth not, thereby cause poor sealing, while using in the environment of fluid is arranged in addition, as be applied on automotive transmission while as oil, blocking up pad, breather plug pad or reverse gear shaft spacer for bolt, easy oil impregnate, and be difficult for tightening.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of sealability better, can prevent oil impregnate and the packing ring that is easy to tighten.
The present invention solves the problems of the technologies described above adopted technological scheme:
A kind of packing ring, comprise the ring body, on described at least one end face of ring body, has been wholely set a bulge loop.
Be wholely set a bulge loop on an end face of described ring body.
Be provided with annular groove on another end face of described ring body, described annular groove is arranged on described bulge loop below.
The width of described annular groove is less than the width of described bulge loop.
The width of described bulge loop with the ratio of the width of described ring body is
arrive
.
The width of described bulge loop with the ratio of the width of described ring body is
.
The material of described ring body is aluminium or copper.
Compared with prior art, the invention has the advantages that: be wholely set a bulge loop on the ring body of packing ring, when this packing ring and bolt are used in conjunction with, the lower surface of bolt head contacts with bulge loop, because area of contact is less, while tightening, bolt head lower surface and bulge loop form extruding, can make up the sealability caused due to the out-of-flatness of bolt head lower surface bad, the defects such as oil impregnate, the bulge loop below is provided with groove in addition, while tightening, bolt head lower surface and bulge loop form extruding, produce distortion, and the bulge loop of crushed element is expressed in groove, can use less power by bolt tightening, sealing and the performance that prevents oil impregnate have been guaranteed better simultaneously.
The accompanying drawing explanation
The structural representation that Fig. 1 is the embodiment of the present invention one;
The structural representation that Fig. 2 is the embodiment of the present invention five.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
Embodiment one: as shown in Figure 1, a kind of packing ring, comprise ring body 1, on an end face of this ring body 1, has been wholely set a bulge loop 2.
The width of this bulge loop 2 is d, and the width of ring body 1 is D,
for
.
The material of ring body 1 is aluminium.
Embodiment two: other parts are identical with embodiment one, and its difference is that the material of ring body 1 is copper.
Embodiment three: other parts are identical with embodiment one or embodiment two, and its difference is
for
.
Embodiment four: other parts are identical with embodiment one or embodiment two, and its difference is
for
.
Embodiment five: other parts and embodiment one or embodiment two or embodiment three or embodiment four are identical, its difference is to be provided with annular groove 3 on another end face of ring body 1, this annular groove 3 is arranged on bulge loop 2 belows, and the width L of this annular groove 3 is less than the width d of bulge loop 2, as shown in Figure 2.
