The structure and working principle of overlap wave spring

What we are interested in is how to improve the performance of the spring. Breakthroughs in technology. Building the Lisheng brand for 100 years.

Nested Wave Spring washer

On the outer peripheral portion of the main body of the single turn overlap wave spring washer, a plurality of teeth that are substantially rectangular and protrude radially outward are formed at equal intervals in the circumferential direction. A stress relaxation portion is provided at the root portion of the tooth, and the stress relaxation portion has a flat portion. The flat portion is formed by, for example, processing the edge portion at the circular arc portion of the root portion of the tooth into a flat shape by embossing.

 

When the single turn overlap wave spring washer is applied to the clutch mechanism of the conveying machine, the stress generated at the root of the teeth when the clutch is engaged can be reduced by the stress relaxation part. Furthermore, even when the shape of the spline groove of the clutch drum is sharp, the interference between the teeth and the spline groove when the clutch drum is rotated can be prevented, so that the wear of the spline groove caused by the teeth can be reduced. Therefore, the disc spring can have high durability.

 

The single turn overlap wave spring washer is a special spring that is tapered in the axial direction and bears the load. After being deformed by the load, it stores a certain potential energy. When the bolt loosens, the disc spring releases part of the potential energy to maintain the flange connection. The pressure meets the sealing requirements. The stress distribution of the disc spring decreases uniformly from the inside to the outside, which can achieve the effect of low stroke and high compensation force.

Multi Turn Wave Springs

The principle of single turn overlap wave spring washer

The disc spring is a special spring that is conical in the axial direction and bears the load. After being deformed by the load, it stores a certain potential energy. When the bolt loosens, the disc spring releases part of the potential energy to maintain the pressure between the flange connections. sealing requirements.

The stress distribution of the overlap wave spring decreases uniformly from the inside to the outside, which can achieve the effect of low stroke and high compensation force. It has high rigidity, strong buffering and vibration absorption capacity, and can bear large loads with small deformation, which is suitable for occasions with small axial space requirements. With variable stiffness properties, this spring has a wide range of nonlinear properties. Using different combinations of the same disc spring can change the spring characteristics in a wide range. The combination of involution and stacking can be used, and the combination of different thicknesses and different numbers of sheets can also be used. When overlapping, the more the number of springs, the greater the load relative to the same deformation.

 

The overlap wave spring is formed into a conical disc shape. As a sealing aid, it can be used alone or in series or in parallel. The upper inner edge and the lower outer edge are subjected to static or dynamic loads acting in the axial direction and are compressed. Afterwards, it deforms until it is flattened, and takes the form of stored energy as a live load. When necessary, it is automatically converted into an additional compression load required by the seal, so as to reduce the continuous requirements for tightening in the use of gaskets and packings, and reduce unnecessary Downtime for repairs and leakage losses.

 

Features of overlap wave spring

  1. High rigidity, strong buffering and vibration absorption ability, can withstand large loads with small deformation, and is suitable for occasions with small axial space requirements.
  2. With variable stiffness characteristics, this spring has a wide range of nonlinear characteristics.
  3. Using different combinations of the same disc spring can change the spring characteristics in a wide range. The combination of involution and stacking can be used, and the combination of different thicknesses and different numbers of sheets can also be used.
  4. When overlapping, relative to the same deformation, the more the number of springs, the greater the load.

single turn overlap wave spring washer

Compared with the cylindrical coil spring, the overlap wave spring has the following characteristics:

  1. The load-deformation characteristic curve is nonlinear.
  2. The disc spring is in the shape of a thin sheet, which is easy to form an assembly, and can be assembled and replaced by building blocks, thus bringing convenience to maintenance.
  3. Disc springs with radial grooves have zero stiffness characteristics. This characteristic can be used in occasions where the spring force is required to be basically stable within a certain deformation range.
  4. The vibration absorption performance of the disc spring is not lower than that of the cylindrical coil spring. When the overlapping combination is used, it has a greater damping due to the friction between the disc springs and dissipates the impact energy.

 

Application of disc springs: In a wide range, disc springs are replacing cylindrical coil springs. It is often used in heavy machinery (such as presses) and cannons, aircraft and other weapons, as a strong buffer and vibration damping spring, as a compression spring for clutches and safety valves of vehicles and tractors, and as an energy storage element for motorized equipment.
