In order to meet the operation of some products, people invented the disc spring. There are not many classifications of disc springs on the market. Disc springs, also known as Belleville spring washers, were invented by the French more than 100 years ago. The shape of the disc spring is a conical disc, and compared with the traditional spring, it has a different function; the disc spring has a short stroke, simple operation and convenient maintenance.
The role of the disc spring
The shape of the disc spring is a conical disc, which is different from the traditional spring and works in action. The load is large, the stroke is short, the required space is small, the combination is convenient, the maintenance and replacement are easy, and the economic safety is high. Ideal for precision heavy equipment with little space and heavy loads, compression strokes use 10%-75% of large compression strokes well.
The stroke is short and the load is large. Requires little space. Easy to use in combination. Easy maintenance and replacement. Economical and safe.
Surface treatment: add lubricating oil after phosphoric acid treatment
Extraordinary surface treatment: galvanized, steel, bright, metal film, paint, etc. electroplating can produce a carbide layer. If you need extraordinary surface treatment, please come to our company to review.
1. When the disc spring is used in series, it needs to have an inner guide or jacket ring, and the inner guide or jacket ring needs to be heat treated to HRC52 degrees and then polished.
2. See the table below for guide post installation and fragment spacing tolerances.
Coupled spring curve
(a) 3 parallel stacks, 1 stroke, 3 times the elasticity.
(b) 4 serial overlapping methods, 4 strokes, the elasticity is 1 times.
(c) Three parallel stacks, three strokes, twice the elasticity.
(d) In order to make the reduction curve of the parallel overlapping method parallel to the disc springs of different thicknesses, it is necessary to combine the progressive curves in series, and the weak springs need to have a protective overload design.
Friction coefficient and shock absorption
A. Constant momentary blows will reduce the life of the spring.
B. When the spring is overloaded or the pressure is quickly relieved, the spring will appear hysterical, causing the spring to chafe.
The compression of the disc springs operates from 10% to 75% of travel
Application: Disc springs are replacing cylindrical coil springs on a large scale. Mainly used in large machinery (such as presses), as buffer and damping springs, compression springs for vehicle and tractor clutches and safety valves, as energy storage elements for motorized equipment.
