Advantages of disc springs

Disc springs are conical in shape, it has been invented for more than one hundred years and got a wildly application during the last few decades because of many advantages, such as:

  •   High load capacity with small deflection

  •   Long fatigue life

  •   Space savings

  •   Largely Self-damping, giving good shock absorption and energy dissipation

  •   Singly or in stacks to meet various requirements

  •  Various characteristics due to different thickness and height

  •   Low Maintenance cost & Greater Security

So, we can find disc spring in many industries: auto, heavy  machinery, elevator, valve, wind turbine, off highway, chemical plant, steel plant, electric switch ......

Typical applications

  • Automotive & Engines

  • Clutches, brakes

  • Valves, pumps

  • Machine Tools

  • Screwed or bolted sections.

  • Bearing preload.

  • Hoists, cranes

  • Electrical switch gear

  • And many more applications

We provide disc springs as per DIN2093, there are 3 groups in the range,

                group 1   thickness less than 1.25mm

                group 2   thickness from 1.25mm to 6mm

                group 3   thickness larger than 6mm

   When the thickness is larger than 6mm, we can select a disc spring with a seating.

We are capable to manufacture the standard size range in outside diameters from 10mm to 400mm, thickness from 0.4mm to 16mm, and there are many coatings are available such as  Phosphating,   Dacromet, Delta, Geomet, etc.

 Other materials on your request

 

Coating

For the coating, Phosphating is the standard process generally applied to all low alloy steels.

 

Special finishes readily available include mechanical zinc plating, Dacromet, Delta, Geomet. the latter two can resist mort than one thousand hours salt spray test.

 

 


 

Disc spring characteristics

 

 

                         Test characteristic of springs

For the normal range of disc springs, In the usual working range C the actual measured curve  very closely coincides with the theoretical.

when the deflection s>0.75ho the force increases sharply,  due to  the smaller lever arms, so the measured curve deviates from the calculated curve. so force/deflection predictability is limited to 75% of total deflection (ho).

 

 

 

 

 

 

 

Spring characteristic curve with respect to         

h0/t and s/h0                                  

 

In many cases we want the spring load increases progressively as the deflection increases, But the load/ deflection curve of most disc springs are nonlinear. The curve becomes increasingly curved as the ratio ho/t increases. 

Up to a ratio of 1.5, disc springs may safely be taken to the flat position. Above 1.5 the disc spring is capable of push-through, over 2 the spring may invert when the deflection is close to ho.

 

 

 

 

 

                                                                                                                                               Fc is the force at flat

 

                                  Spring stacks curve

                         

 

Disc springs can be statically loaded either continuously or intermittently, or dynamically subjected to continuous load cycling. They can be combined in different ways,  the various combinations can get almost any characteristic to meet the requirements.

 

 

 

 

 


Tolerances to DIN2093

We apply the following tolerances as per DIN2093, if you have different requirement please show us.


 

Selecting Disc Spring Guidelines

  •  With temperatures increasing, disc springs begin to lose their spring characteristics. When the service temperature exceeds 200˚C, special materials should be used.  If the service environment is severe, corrosion resistance material should be considered, such as SS301,SS304,SS631 or SS316.

  • Select larger outside diameter can reduce deflection to get the same force and thus enhances fatigue life.

  • Usually we select a disc spring load at 0.75ho can offer the maximum force required. the service deflection  from 20% to 70% of total disc spring deflection can get higher fatigue life.   

  • Shorter disc springs stack and parallel can reduce the effect of friction, Lubrication is efficient also.

Arbort disc springs have the advantage of good quality, better price and service in the market, especially in the stainless steel and super alloy disc springs rang. In addition to the standard materials and sizes mentioned above, we are looking forward to manufacture disc spring as per your drawing or develop special disc springs to meet your requirements of the application. So if you have the application of disc springs, why not send a inquiry to find some opportunities to improve your product's market advantage?
