Characteristics of disc springs

     DiscSpringAlso known as Belleville spring washer, it was first invented by Frenchman J. Belleville over 100 years ago.Disc springIt is a type of washer spring made of metal sheet or forged blank with a truncated conical structure. Its shape is conical disc-shaped, different from traditional springs. The main development characteristics are large load, short stroke, small required time and space, more convenient combination use, easy maintenance and replacement, and high economic security. It is suitable for precision heavy machinery with small space and large load. The selection and management range of its compression stroke can be between 10% to 75% of its developed compression stroke.

Disc springIt has advantages such as short stroke, small deformation, and large load capacity. Compared with other types of springs, it has a higher space utilization rate. Different spring combinations can achieve the desired load characteristic curve. It is easy to maintain and replace various special materials and surface coatings, has high economic security, and long service life. Disc springs mainly rely on the deformation of the pre-tightening structure to solve the technical problem of loosening. In terms of working principle, the thicker the disc spring, the greater the pulling force provided, and the greater the resistance to pulse pressure; the thinner the disc spring, the thicker the height when freely expanded, the greater the allowable deformation provided. Since the tension determined by the thickness of the disc spring is inversely proportional to the amount of deformation, it is a pair of contradictions. Therefore, when the pulling force or deformation provided by a single disc spring cannot meet the working condition requirements, it can be solved by combining disc springs.

Disc springIt can be used by a single enterprise or combined with multiple disc springs to withstand static or variable loads. The edges of the disc springs with supporting surfaces are rounded, greatly reducing the friction loss caused by rebound during use. It can be used alone, or combined in different combinations, or combined with composite materials to form a disc spring group. It withstands static loads or variable loads. It is suitable for heavy machinery or molds with small installation space and large loads. Currently, engineers in technologically advanced countries such as Europe, America, and Japan have applied disc springs to a large amount of data in mechanical electronic components. In addition to considerations of national security technical performance, it has also replaced traditional helical springs with network space, limited load, and excessive compression stroke, improving the performance of student machinery.

Disc springMain function: It can be applied to bolts with not very large actual load capacity but severe vibration; it can effectively prevent bolt loosening and prevent wires from falling out of the bolts; it can play a locking role, compensate for pre-tightening force, and ensure that the system is sealed, durable, stable, and reliable; the anti-loosening disc spring has good universality for bolts and equipment.

High torque loading disc springs: In our country, valves and pipelines use high torque for the pre-tightening of flange connection bolts; pre-tightening of foot bolts and flanges for fans, pumps, and centrifuges; pre-tightening of heat exchanger, reactor, and stirrer flange bolts; pre-tightening of clutches, generators, and pipeline support and hanger system devices; pre-tightening of power working bus bolts; various social information engineering technology applications such as buffer protection devices, brake control devices, and high-pressure cable temperature compensation standard devices.
