Abstract
A six-claw spring relates to a heterosexual spring that is a disk-like spring, and is characterized in that the outside circle along the disk-like spring is divided into six equal centrosymmetric support angles to form six claws, and the lower end face of the support part of each claw is wider than the upper end face of the disk-like spring. The six claws are uniformly distributed along the circumference, and the outer edges of the six claws are positioned on the same circle. The inner circle of each claw is provided with a round hole, and the rounds holes and the external circle formed by the six claws are concentric. The six-claw spring has the beneficial effect that problems of transitional flanging and unstable height can be avoided when the disk-like spring is higher through changing the shape of the disk-like spring.
Description
Technical field
The utility model relates to different in nature spring, especially a kind of hexa-claw shape belleville spring.
Background technique
At present, known common belleville spring height is less, if the height design of belleville spring is too high, it is highly unstable, when being subjected to external pressure, if the phenomenon of transition flange will appear in belleville spring when decrement is excessive, free height can reduce, and influence is used normally.How solving belleville spring is subjected to pressure all over just seeming particularly important with the height problem of unstable.
The model utility content
The technical problem that the utility model solved is to provide a kind of height height of the common belleville spring of aspect ratio of thrust load direction, and highly stable, the flange phenomenon can not appear, can be used as the resilience of various device, six latch springs of energy storage.
The technical problem that the utility model solved realizes by the following technical solutions:
A kind of six latch springs are a dish-shaped spring, are divided into six centrosymmetric strut angles of five equilibrium at the cylindrical along belleville spring and form six pawls, and the support zone lower end surface broad of described six pawls is greater than the upper-end surface of belleville spring.
Described six pawls evenly distribute along circumference, and the outer rim of six pawls is on same circle.
The inner ring place of described six latch springs is provided with a circular hole, and and the cylindrical formed of described six pawls be a concentric circle.
The beneficial effects of the utility model are by changing the shape of belleville spring, have solved the belleville spring height and have occurred transition flange and height problem of unstable when higher.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the plan view of Fig. 1;
Power when Fig. 3 is the utility model pressurized-deformation characteristic plotted curve.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As depicted in figs. 1 and 2, a kind of six latch springs are a dish-shaped spring, make more smoothly than the end face of common belleville spring in the upper-end surface 1 of six latch springs, and when stressed, contact plane strengthens.Lower end surface 2 at six latch springs is designed to smooth angle.Between the upper-end surface 1 of six latch springs and lower end surface 2, form lever wall supporting part 3, make circular arc.The supporting part 3 of circular arc extends to form six pawls 4 downwards.Six pawls 4 evenly distribute along circumference, and the outer rim of six pawls 4 is on same circle.Be the arc transition portion 5 that connects the two ends straight line of a pawl between pawl 4 and lever wall supporting part 3, and and the outside straight line intersect and inner straight line is tangent.The arc transition place 6 and two straight lines of two sections straight lines of two pawls of 1 adjacent connection are tangent in the upper-end surface.Make arc transition 7 at the position that connects lever wall supporting part 3 and six latch spring lower end surfaces 2.
As shown in Figure 3, power when being six latch spring pressurizeds-deformation characteristic plotted curve, wherein 8 is that the negative stiffness place appears in six latch springs first, and 9 is that the negative stiffness place appears in six latch springs for the second time. and one section the curve that begins to compress when six latch springs is a near linear, increase along with decrement, the negative stiffness zone appears twice, and extremely unstable at this interval spring, along with decrement increases, the lever wall of six latch springs begins to reduce, the minimizing of lever wall, the increase of exerting all one's strength is till flattening.
As shown in Figure 2, also be shaped on the cylindrical that a circular hole 10 and six pawls 4 form at 1 place, six latch spring upper-end surfaces and be a concentric circle.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
