What is the use of a corrugated washer?

　　Corrugated WasherWhat is its use?

　　A corrugated washer is a thin metal ring with multiple crests and troughs in each layer. It is commonly used in spacecraft, bearings, flow valves, pressure valves, clutches, vibration isolators, axial plunger pumps, drivers, and other equipment. Corrugated washers are suitable for connecting bolts and screws in the 8.8~10.9 high-strength range. It can compensate for the connection of bolts and screws, preventing stretching, wear, creep, thermal expansion, shrinkage, and compression of the seal.

　　First, the corrugated washer disperses the nut pressure on the connector.

　　Corrugated WasherIt is a part used to protect the surface of the connector from being scratched by the nut. The dispersed nut pressure is on the connector and placed between the connector and the nut. Usually, a flat metal ring is used to disperse the pressure of the nut on the connecting part.

　　Before placing the corrugated washer, the bottom end face of the weight is set to the zero position of the dial indicator from the axial through hole. After placing the corrugated washer in the groove and adding the weight, the peak deformation causes the dial pointer to retract inward, and the retraction amount is the measured elasticity index value. This utility model patent technology vertically loads heavy objects in the positioning state, the force is uniform, the elastic deformation is real, the measurement result is accurate, and the detection operation is convenient.

　　Second, the corrugated washer has a special shock absorption function.

　　The corrugated washer is specially heat-treated, and the hardness is generally controlled between HRC44-55 according to the specific situation. The surface is black, and the elasticity is good. It is widely used in motors, textile machinery, hydraulic equipment, automobiles, and other industries. It is mainly equipped with bearing chambers or holes of appropriate Specification (nominal Size), with small installation space and special noise reduction and vibration damping functions.

　　The fixing of parts on the corrugated washer shaft can be divided into axial fixing and circumferential fixing. Axial fixing methods include: fixing shoulder or shaft ring, fixing shaft end ring or cone, fixing shaft sleeve, fixing round nut, fixing elastic retaining ring. The retaining ring mainly plays an axial fixing role, and the concentricity of the cone with the retaining ring is higher.

　　Third, the elasticity index of the corrugated washer is easy to test.

　　The corrugated washer is specially heat-treated, and the hardness is generally controlled between HRC44-55 according to the specific situation. The surface is black, and the elasticity is good. Corrugated washers are widely used in motors, textile machinery, hydraulic equipment, automobiles, and other industries. They are mainly equipped with bearing chambers or bearing holes of appropriate Specification (nominal Size), with small installation space and special noise reduction and vibration damping functions.

　　A simple testing device for the elasticity index of a washer, consisting of a weight, a base, screws, supports, a dial, and a groove. The base is disc-shaped, and the weight is placed in the upward cavity. There is an axial through-hole in the middle of the cavity for installing the lever, and the lever is fastened with screws. The bottom end of the base is supported by feet.

　　Fourth, the outer edge of the corrugated washer seat has a thickened layer.

　　Corrugated WasherThe outer edge of the base has a thickened layer; the upper surface of the baffle has an inner arc surface. The manufacturing process is simple, the structure is reasonable, and the retaining ring has good elasticity. The original plane contact is changed to inner arc contact, which effectively reduces the stress of the fixed part, making the fixing firm and the positioning accurate. Through the design of the thickened layer, the service life and work efficiency are improved.
