Description
Technical field
The present invention relates to the bowl-type packing ring a kind of pressing end face being provided with flange, it is applicable to the rugged environment being in vibration for a long time, impacting, and can be applicable to engineering machinery, railway locomotive, harbour machinery, bridge works, textile manufacturing machine etc.
Background technique
For solving the antivibration of threaded fastener, anti-loose, scheme conventional at present adopts spring washer, nylon embeds, pin, distortion screw thread, the methods such as mighty bond is bonding, they loosen voluntarily although can delay threaded fastener to a certain extent, the time come off, but cannot tackle the problem at its root, particularly wherein using scope is the widest, consumption is maximum, the good spring washer of antivibration effect, be in the rugged environment of vibratory impulse for a long time, continuous appearance is because of separation of scattering after spring washer brisement, come off and the accident caused, historical facts or anecdotes can not be satisfactory in using.
Summary of the invention
Be in the rugged environment of vibratory impulse for a long time to overcome the existing threaded fastener being furnished with spring washer, separation of scattering is there is after cannot overcoming the spring washer brisement on it, the shortcoming such as come off, a kind of structure of special proposition is simple, easy to use, can according to the concrete needs of the spring washer of different size, its pressing end face is provided with there is reasonable depth and geometrical shape the geometric form flange that can protect this spring washer (even if there is brisement and the situation of scattering in this spring washer, this flange also can guarantee the brisement body on this spring washer to protect and the brisement body that can not occur on spring washer is separated with threaded fastener the caused accident that comes off) a kind of pressing end face on be provided with the bowl-type packing ring of flange, to make up current deficiency.
For achieving the above object, technological scheme of the present invention is achieved in that the bowl-type packing ring a kind of pressing end face being provided with flange, the pressing end face that it is characterized in that this bowl-type packing ring is provided with at least one match with spring washer can prevent spring washer brisement after scatter and be separated, the geometric form flange come off, to be internal thread on the nut by matching with the bolt mated with this nut externally threaded coordinate to screw matches with the described spring washer be enclosed within bolt and put in place and rely on geometric form flange to be encircled for protection by spring pad for described pressing end face and geometric form flange thereof, with reach prevent spring washer brisement after to scatter separation, the object come off.
Preferably, described geometric form flange preferably has the round flange that the degree of depth is 1.8 ~ 32 millimeters.
Certainly, the geometric form flange that the pressing end face of described bowl-type packing ring is arranged can have multiple geometrical shape, can be the shapes such as circle, sunflower-shaped, interior octagon, wherein circular best, and can select the different degree of depth from spring washer Proper Match as required.
According to the present invention, a kind of pressing end face is provided with the bowl-type packing ring of flange, its working principle and using method are that by the threaded end contraposition on the bolt that mates with this bowl-type packing ring, through the matching hole of connected piece, (this matching hole can select circle as required on request, square, double-U-shaped, the pass that rectangle etc. are different), then spring washer contraposition is put in the geometric form flange that the pressing end face of this bowl-type packing ring is arranged, again the pressing end face one end contraposition matching this bowl-type packing ring of above-mentioned spring washer is packed into the threaded end on bolt, namely finally screw the nut that mates with it and lock installs (even if be in vibratory impulse for a long time, the rugged environment of exposing to the sun and rain, above-mentioned spring washer is caused to occur brisement and the situation of scattering, due to the protective action of geometric form flange, therefore the brisement body of above-mentioned spring washer can be guaranteed to protect and stop the brisement body occurred on spring washer and be separated with threaded fastener the caused accident that comes off).When need unload, first the nut derotation of mating with it is unclamped and taken off, then this bowl-type packing ring is unloaded from bolt.
Bowl-type packing ring pressing end face being provided with flange can by a multiple material, as carbon steel, stainless steel, aluminum alloy, macromolecular material etc. are made, by kinds of processes, as the methods such as die forging, cold-heading, punching press, injection moulding form.Profile and the large I of this bowl-type packing ring are determined as required, preferably can diversified, standardization.
The present invention has following major advantage: (1) strong adaptability, be applicable to be in for a long time vibration, impact so Exposure to Sunlight, the rugged environment that drench with rain, can be applicable to engineering machinery, railway locomotive, harbour machinery, bridge works, textile manufacturing machine etc.; (2) structure simple, easy to use, also the geometric form flange of different depth and shape can be selected to match according to the needs of joined spring washer; (3) material is easy to get, and technique is simple, and cost is low, can standardization, can exchange, general; (4) can mate with spring washer preferably and use, shock resistance, anti-vibration satisfactory for result, separation of scattering after spring washer brisement can be prevented, to come off, can stop because the brisement body on spring washer is separated with threaded fastener the caused accident that comes off.
