DİSC SPRING TECHNICAL DRAWING

       Disc springs, steel utensils and load the dish-shaped hole in the middle of an element under the influence of yaylanabilen.
      Disc springs, according to the ratio between the thickness of the height of the TS 1443 / - and TS 1443 / 2, is standardized. Thickness of 3.5 mm cold-rolled sheet produced in small springs spring steel band or sheet, the hot rolled steel sheet thickness 3.5 mm, large springs are made of steel band or sheet.
      Disc springs on top of one sort and the middle pin is used to hold the bow.
Discs in the opposite direction one by one by placing a very small spring force of spring can be provided. For each group by using multiple disk spring so the spring force is provided at least springing.

Explanation of the tables
            The following tables list the spring tı DIN 2093 as well as those to Schnorr Works Standards. Those to DIN 2093 are shown in heavy type. The prefix A , B and C show the corresponding series. All sizes are normally kept in stock  and the heavy type does not indicate a beter delivery.

            The article number guoted is for normal manufacture from spring steel with phosphate finish.

Load and stres specifications
           The load and the corresponding stresses are given for the four points s = 0.25 h0  ,
s = 0.5 h0   , s = 0.75 h0    and  s = h0  . The quoted stres at s=0.75 h0 is the tensile stres on the underside at point II or III whichever is the greater.

            Static or infrequently loaded springs may be compressed to the flat condition ( see section 2.1 ). Lt should be noted that from s=0.75 h0    the actual characteristic progressively increases from  that  calculated ( see sections 1.7 and figure 10) .
For dynamic  application the calculation in section 2.2 must be completed.
All values are based on a Young ’s modulus “ E ”  of 206000 N/mm2  with µ=0.3 and are the refore only valid for Disc Springs from springs steel to DIN EN 10132 – 4 and DIN 17221 (e.g. 51 CrV 4 or C 67S ). The  use of other materials  necessitates recalculation  with the correct value for Young ‘s modulus “ E “ . For lo1  ver tensile  strength  the free height  h0 and the overall height  I0  must be amended ( see chapters 1 and 2 ).
When considering  the use of special sizes or  springs form  special materials we recommend you leave the work to us. We will be pleased to go through  the necessary calculaticns quickly , at no cost  and adsive you of the pcssibilities of manufacture.
