Abstract
A spring gasket in the utility model is a single loop of cylindrical helical spring [1], the cross section of a spring wire is a rectangle and one pair of sides is disposed on a column surface, and upper and lower surfaces are provided with zigzag corrugations [a] in a radial arrangement. The spring gasket in the utility model is formed by manufacture of the zigzag corrugations on the two surfaces of a common spring gasket, compared with the prior art, the spring gasket is advantageous in that flexibility is sufficient, sawteeth are not easily flattened, and can be pressed to parts on the two surfaces, making rotation of screws or nuts difficult so as to strengthen anti-thrust effect.
Description
Technical field
The utility model relates to a kind of spring washer, belong to the spring washer technical field of common engineering in the mechanical engineering.
Background technique
Spring washer designs for the screw stopping, and normally the cylindrically coiled spring of individual pen for improving its stopping function, also has the integral type spring washer to use, and its structure is that the plain washer inner ring has been opened a plurality of wings, and each wing is converted into spring sheet.Another kind of and spring washer similarly is used for the packing ring of stopping, is the sawtooth lock washer.But its thickness is less usually for this lock washer, is to form sawtooth through rolling over stubborn mode in the plane at packing ring inner ring or outer ring, and one is that elastic force is less when fastening, the 2nd, be driven plain easily, and make stopping function still strong inadequately.
Summary of the invention
To above-mentioned deficiency, the utility model is exactly the spring washer that will provide a kind of stopping function powerful.
The spring washer that the utility model provides is the cylindrically coiled spring of individual pen, the spring thread cross section be rectangle and an opposite side on cylinder, the flexuose ripple of arranging is radially arranged on its upper and lower surface.
The spring washer that the utility model provides is made the flexuose ripple and is formed, compared with prior art on common spring washer two sides; The utility model elasticity foot; Sawtooth is difficult for being driven plain, and can be pressed into the part on the two sides, makes screw or nut rotate difficulty and the effect of reinforcement stopping.
Two of every sawtooth in the said flexuose ripple are domatic, wherein meet to the gradient of tightening direction more slow, meet to the gradient of rotational direction steeper, thereby make screw or nut further improve the stopping effect greater than tightening direction to the rotational resistance of loosening direction.
Description of drawings
Fig. 1 is the utility model one embodiment's a plan view, and Fig. 2 is the three-dimensional structure diagram of the utility model, among the figure: 1-spring washer, a-sawtooth.
Embodiment
One is used for the spring washer 1 of right-handed thread, is one by the individual pen cylindrically coiled spring made from the spring thread of rectangular cross-section, and the Hand of spiral of spring is left-handed, make when tightening screw afterbody or nut lower end surface and workpiece surface relatively packing ring slide.Its upper and lower surface all has the sawtooth ripple, and every sawtooth a in the sawtooth ripple arranges by the radial ray that with the packing ring axis is the center, thereby forms the sawtooth ripple that annular rises and falls.During two of every sawtooth are domatic; Meet to anticlockwise one side be one with the face of parallel axes; Sawtooth is met the lower end surface to screw afterbody or nut with the inclined-plane when promptly tightening; And screw or nut be when counterclockwise rotating (rotational direction), and sawtooth is met the lower end surface to screw afterbody or nut with vertical surface.In addition, all will spring washer be heat-treated for improving its hardness in the existing technology, what then sufficiently high hardness can make that sawtooth has a certain depth is pressed into workpiece surface even screw afterbody or nut lower end surface.Like this, the spring washer that this example provides provides the stopping function aspect two, and the one, elasticity links closely internal and external threads, and loosening resistance increases; The 2nd, sawtooth both sides different slope increases loosening resistance; The 3rd, sawtooth is pressed into workpiece, and loosening resistance is increased.
Claims (2)
1. a spring washer is the cylindrically coiled spring of individual pen, the spring thread cross section be rectangle and an opposite side on cylinder, it is characterized in that on the upper and lower surface of spring washer the flexuose ripple of arranging radially being arranged.
2. spring washer as claimed in claim 1 is characterized in that two of every sawtooth in the said flexuose ripple are domatic, wherein meets to the gradient of tightening direction more slowly, meets to the gradient of rotational direction steeper.
