Abstract
The invention aims at providing an anti-loosening gasket, which is used for effectively increasing frictional force between a connected piece and a nut, preventing the circumstances that the connected piece gets loose during use, and avoiding accidents caused by connection failure. The anti-loosening gasket provided by the invention comprises a gasket main body made from a metal material, wherein the gasket main body is provided with a through hole. The anti-loosening gasket is characterized in that elastic anti-slip layers are arranged on the two side faces of the gasket main body. The frictional coefficient between metals is about 0.1-0.2. After the gasket is additionally provided with the elastic anti-slip layers, the frictional coefficient among the gasket, the nut made from a metal material, and the connected piece can be greatly increased, and the stress of a whole connecting surface of a bolt can be more uniform when the anti-loosening gasket is connected with the bolt, so that the friction between the nut and the gasket as well as between the gasket and the connected piece is greatly increased under the condition of the same pre-tightening force, the firmer bolted connection is ensured, and meanwhile, a good sealing role is played.
Description
Technical field
The invention belongs to the auto parts and components field, in particular, the present invention relates to a kind of novel check washer.
Background technique
In using bolted product, often all need use on pad, particularly machinery and the automobile.If the employing rubber sheet gasket is too big if pretightening force applies, cause rubber to lose efficacy easily; If the use metallic shim, the intermetallic friction factor is lower, and under the operating mode of big load and vibration, bolt can become flexible easily, causes bolt to connect inefficacy and has an accident.
Summary of the invention
The objective of the invention is to propose a kind of check washer, effectively increase the frictional force between connected piece and the nut, prevent that situation about becoming flexible from use appearring in connected piece, avoid the connection inefficacy and cause accident to take place.
Check washer of the present invention comprises the gasket body of metal material, and gasket body has through hole, and key is that the side, both sides of said gasket body is provided with the elastic anti-slip layer.Friction factor is about 0.1～0.2 between the metal, and above-mentioned pad can improve the nut of pad and metal material and the friction factor between the connected piece greatly after setting up the elastic anti-slip layer; And whole bolt junction surface is stressed more even when bolt is connected; Thereby under the situation of identical pretightening force, nut and pad are provided greatly, the frictional force between pad and the connected piece; It is more firm to guarantee that bolt connects, and can also play good seal action simultaneously.
Specifically, said skid resistant course has following three kinds of forms:
1, said skid resistant course is the rubber layer that vulcanizes in the gasket body surface, and this kind skid resistant course combines with gasket body closely, long service life;
2, said skid resistant course is the plastic layer that is pasted on side, gasket body both sides, and this kind skid resistant course cost is low, is easy to processing.
3, said skid resistant course is circular rubber sleeve, and the middle part of said rubber sleeve has breach, and said gasket body is positioned in the rubber sleeve through said breach, and this kind skid resistant course is easy to process, cost is low, and skid resistant course combines closely difficult drop-off with gasket body.
Further, the thickness of said skid resistant course is 0.3mm～1mm, confirms through overtesting: the thickness of skid resistant course is crossed to approach and can be reduced the frictional force between connected piece and the nut, and thickness is crossed the rigidity that affects connects.
Further, for improving friction factor, the surface of said skid resistant course is provided with concavo-convex decorative pattern.
Check washer of the present invention is simple in structure, realizes easily on the technology, and is with low cost, reliable performance; Promoted nut and pad greatly, the friction factor between pad and the connected piece, it is loosening to have prevented that effectively bolt from connecting; Prolong the fatigue life of connected equipment, improved bolted Security, avoided accident to take place; Not only be applicable to conventional the connection, had good sealability simultaneously, can use as the gasket seal of main equipment.
Description of drawings
Fig. 1 is the plan view of check washer of the present invention.
Fig. 2 is the sectional view of check washer of the present invention.
Embodiment
Contrast accompanying drawing below; Through the description to embodiment, the effect of mutual alignment between the shape of specific embodiments of the invention such as related each member, structure, the each several part and annexation, each several part and working principle etc. are done further to specify.
Embodiment 1:
Like Fig. 1, shown in 2, the check washer of present embodiment comprises the gasket body 1 of the metal material of annular, and gasket body 1 has through hole 2, and the side, both sides of gasket body 1 is provided with elastic anti-slip layer 3.The rubber sleeve that skid resistant course 3 has the circle of breach for the middle part, gasket body 1 is positioned in the rubber sleeve through said breach, and the diameter of breach is decided according to the size of gasket body 1, and assurance gasket body 1 can be packed in the rubber sleeve smoothly.The Inner Dimension of rubber sleeve is put into rubber sleeve and can be clamped by rubber sleeve later to guarantee gasket body 1 than the undersized of gasket body 1.
The thickness of skid resistant course 3 is 0.7mm.
Above-mentioned gasket body 1 is after setting up elastic anti-slip layer 3; Can improve the nut and the friction factor between the connected piece (friction factor between metal and the rubber can increase to 0.5 to 0.8) of pad and metal material greatly; And whole bolt junction surface is stressed more even when bolt is connected; Thereby under the situation of identical pretightening force, nut and pad are provided greatly, the frictional force between pad and the connected piece; It is more firm to guarantee that bolt connects, and can also play good seal action simultaneously.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technological scheme carry out; Or design of the present invention and technological scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
