Abstract
The utility model discloses a wedged locking washer structure and relates to a wedged locking washer structure preventing bolts from loosening under severe working environments with large vibration load. The washer structure comprises an annular washer 1 and at least one annular washer 2. Each washer is formed by a washer body and protection layers covered on two faces of the washer body, the protection layers are zinc based chromate protection layers, the washer body includes a washer substrate and sawteeth which are disposed in radial form on two faces of the washer substrate, concentric with the substrate and corresponds to each other, and slope angles of sawtooth faces formed by the sawteeth is 3-7 degrees. The washer structure is realized through mutual meshing of the sawtooth faces of the washer 1 and the washer 2, has the advantages of reasonable structural design, fine locking effect, high strength, strong heat and corrosion resistance, low cost and long service life, and can effectively prevent bolts from loosening under severe working environments with large vibration load.
Description
Technical field
The utility model relates to a kind of bolt lockmaking anti-loose structure, and this structure can prevent that bolt from producing in bigger oscillating load and bad working environment loosening, especially relates to a kind of wedging lockmaking gasket construction.
Background technique
Be used for measures such as machine, equipment screw retention are taked to add compression spring, locking wire usually, aural grommet is arranged, lockmaking nut in the prior art, these measures are under bigger oscillating load and bad working environment, the clamping force of bolt still can descend rapidly and cause bolt or nut to get loose, and can not reuse, these measures had both increased cost, it is loosening to prevent effectively that again bolt from producing in bigger oscillating load and bad working environment, thereby directly causes machine, equipment work is unreliable, workmanship descends adverse consequences.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of existing lockmaking gasket construction design, a kind of " wedging lockmaking gasket construction " is provided, and is a kind of reasonable in design, locking effect is good, intensity is high, heat-and corrosion-resistant, preparation process is simple, cost is low, long service life, wedging lockmaking gasket construction easy to install.
To achieve these goals, technical solution adopted in the utility model is: a kind of wedging lockmaking gasket construction, comprise the pad 1 of ring-type, and it also comprises the pad 2 of at least one ring-type.
Described pad is made up of shim body and the protective coating that covered on the body two sides, and described protective coating is a zinc-base chromic salts protective coating.
Described shim body comprise gasket substrate and on the matrix two sides set and mutually corresponding radial sawtooth concentric with matrix, be 3-7 ° by its angle of gradient of the formed serrated face of sawtooth.6 sawtooth are set on each face of described gasket substrate at least.The used material of shim body is a low alloy steel, and sawtooth and gasket substrate are one-body molded by die stamping.Described packing ring is meshing with each other by serrated face with pad 2 by pad 1 and is connected realization.
The utility model is compared with existing gasket construction has following advantage:
1. this wedging lockmaking gasket construction has reasonable in design, locking effect is good, intensity is high, corrosion resistance is strong, preparation process is simple, cost is low, long service life, advantage easy to install, is that a kind of bolt that can effectively prevent produces loosening wedging lockmaking gasket construction in bigger oscillating load and bad working environment;
Because of the utility model be provided with on the matrix two sides concentric with matrix and mutually corresponding radial its serrated face angle of gradient be 3-7 ° sawtooth, when this packing ring places between bolt and the fastener, when bolt or nut are tightened, under the effect of screwing force, packing ring is wedged with the fastener sawtooth with bolt respectively with the serrated face of pad 2 by pad 1 and is contacted;
Because of this packing ring be pad 1 with pad 2 by the serrated face linkage structure that is meshing with each other, under the effect of bigger oscillating load, cause bolt looseness, at this moment the pad 1 in the bolt looseness drive wedging packing ring relatively rotates with pad 2, makes pad 1 produce expansive forces with pad 2 intermeshing sawtooth changing of the relative positions liftings and makes bolt lockmaking locking;
4. because of covered plating zinc-base chromic salts protective coating on the body two sides, its corrosion resistance is 7-10 a times of electrogalvanizing;
5. because of the used material of shim body is a low alloy steel, sawtooth and gasket substrate are one-body molded by die stamping, can reach HRC48-52 by its hardness of heat treatment process.

Embodiment
The utility model is described in further detail by non-limiting example below in conjunction with accompanying drawing.
Embodiment:
The utility model such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 5, a kind of wedging lockmaking gasket construction comprises the pad 1 of ring-type, it also comprises the pad 2 of ring-type.
Described pad is made up of shim body 3 and the protective coating 4 that covered on the body two sides, and described protective coating 4 is for electroplating zinc-base chromic salts protective coating.
Described shim body 3 comprise gasket substrate 5 and on the matrix two sides set and mutually corresponding radial sawtooth 6 concentric with matrix, be 3-7 ° by sawtooth 6 its angles of gradient of formed serrated face.On described gasket substrate 5 each face, 6 sawtooth are set at least.Shim body 3 used materials are low alloy steel 27MnCrB5, and sawtooth 6 is one-body molded by die stamping with gasket substrate 5, can reach HRC48-52 by its hardness of heat treatment process thereafter.
Described packing ring is meshing with each other by serrated face with pad 2 by pad 1 and is connected realization.
This gasket construction further can use needs setting according to the user.
In sum, this Wedged locking washer structure has reasonable in design, locking effect is good, intensity is high, heat-proof corrosion-resistant is strong, manufacture craft is simple, cost is low, long service life, advantage easy to install, is that a kind of bolt that can effectively prevent produces loosening Wedged locking washer structure in bigger oscillating load and abominable working environment.
