Schnorr Disc Springs
Guiding the Disc Spring
Disc springs arranged in stacks require a
guide to prevent lateral movement under load.
Guides may be located on the inside diameter
D or in the outside diameter D of the springs,
but the internal guide is to be preferred. The
following values are recommended for the
clearance between the guide surface and the
inside or outside diameter if the spring: (chart
lists values).
Using close tolerance for the guides, the clearance can be reduced a little since the inside
diameter does not reduce during the stroke
when the edges are at right angles to the flank.
See para. 6.6.
If possible, and particularly on dynamic application, the guide rod and end thrust faces
should be case hardened to a minimum of
RC 55. The guide surface should be turned
CORRECT
to a fine finish, or better still, ground. Additionally, lubrication with a molybdenum
based high pressure grease is recommended.
WRONG
CORRECT
DISC SPRINGS MAY BE USED SINGLY OR IN COMBINATION
When disc springs are used in stacks, effort
should be made to keep the stacks as short
as possible. As the length increases so does
the friction and therefore the deflection of the
individual discs becomes unequal, with the
greatest deflection being at the moving end.
As a guide it is recommended that the stack
length be restricted to approximately 3 times
the outside diameter of the disc, and the largest
disc diameter be used.
DIAMETER
Dj or De
To ensure stackability the end springs should
have their outside diameter in contact with the
abutment faces. This is only possible of course
with an even number of disc springs.
over 16.0
over 20.0
over 26.0
over 31.5
over 50.0
over 80.0
over 140.0
It is necessary to have the inside diameter in
contact when the abutment faces are just a little
larger than inside diameter of the disc springs.
Not more than 2 or 3 discs should normally be
used in parallel for multiple stacks, especially
under dynamic conditions where considerable
heat is generated.

Schnorr Corporation has specialized in the
manufacture of disc springs for more than 50
years. During this period of extraordinary technical development many applications have been
found for Schnorr disc springs because of their
unique characteristics and advantages.
Original SCHNORR DISC SPRINGS offer a
number of benefits with particular mention for
the following features:
1.Load/deflection curves of straight, progressive, or regressive character according to the
design requirements.
2.The simple adjustment of the springs stack
length by the addition or removal of individual
discs, thus altering the spring stack characteristic.
3.An efficient use of space and high spring
forces with small deflections.
4.Self-demanding, particularly with parallel
stacking.
5.No setting or fatigue under normal loads.
6.Long service life.
7.A large range of possible applications for individual spring sizes simplifies stock-keeping.
Term and Symbols
D–Outside diameter in millimeters/inch
d–Inside diameter in millimeters/inch
P–Spring load
h–Formed height of unloaded single disc in
millimeters/inch
OH–Overall height of unloaded single disc in
millimeters/inch
f–Deflection in millimeters/inch
t–Thickness of a single disc in millimeters/inch
Material for Disc Springs
The most important characteristic of a spring
is its ability to absorb elastic deformations
caused by outside loads. Because of their high
load/deflection ratios disc springs are especially
suitable for storing energy, dissipating shock
loads, suspending moving masses, and for load
measurement.
It is preferable to make a spring as small as
possible, so special materials are used which
are highly elastic, or which possess high tensile
strength and a high elastic limit.
They should also have sufficient plastic deformation ability beyond the elastic limit to permit
the manufacture of cold worked springs, as well
as to minimize failure of springs under unexpectedly high loads.
The Design & Manufacturing of Disc
Springs
According to the Standard DIN 2093, there are
three different groups of execution:
Group 1: under 1.25mm
Group 2: from 1.25 to 6.0mm
Group 3: over 6 up to 16mm
Schnorr manufactures the three groups as follows:
Group 1: Cold formed
Group 2: Cold formed, outside and inside diameters turned, corners on inner edge radiused.
Group 3: Hot formed, springs turned all over,
contact surfaces formed, all corners radiused,
and material thickness reduced.
Tolerance
Allowable variations are laid down in Din 2093.
The tolerances on disc spring diameters are
H 12/h 12. The permissible tolerance for the
spring force F at s=0.75 h0 is given in the following table:
The spring force must be measured on a single
disc exactly as specified in the standard.
The following table gives the tolerance for the
over all height OH according to DIN 2093
Since the method is carried out in a drum it is
possible only with larger quantities and limitation of an external diameter up to approximately
80mm. Zinc and Cadmium are lower than steel
on the elector chemical table and therefore
a self protecting effect occurs in the case of
surface damage.
A Chemical Nickel plating surface treatment is
also possible ie, the Durni-Coat process. With
this method embrittlement is also avoided to a
large extent. Because of the greater hardness
of the nickel layer, durability under dynamic
loading comes into question. In the event of
damage, no self protection occurs since nickel
lies higher than steel in the electrochemical
table. Further advice on specific applications
can be obtained from our engineers.
Surface Working
Surface working, especially by shot-peening,
has proved to be beneficial for disc springs
subjected to dynamic loads. The result may
increase the working life far in excess for the
values shown in Figs 8,9 and 10. However,
as shot-peening reduces the internal tensile
stresses arising from scragging, shot-peening
or other methods of surface working are not
recommended for discs carrying static loads.
Since these tolerances were computed for disc
sizes specified in DIN 2093 certain limitations
must be imposed for other discs in which the
dimensional ratios differ from the standard
springs. This also applies in the case of “K”
disc springs.
Heat Treatment
All our springs are austempered. This method
of heat treatment is particularly effective for
springs, as it gives the maximum toughness
and therefore considerable durability.
According to DIN 2093 the hardness should be
RC 42-52 and in manufacture the optimum value
is selected with regard to spring size and tensile
stress.
Pre-setting
After heat treatment each disc spring is
scragged, i.e., pressed flat at least once. By
doing so the spring is preset in such a way that
the overall height OH stays within the permissible tolerance after being subject to loads up
1.5, the maximum force at f=h.
Surface Protection
Unless stated, all our disc springs are supplied
Phosphated or oil blackened before oil dipping.
The Phosphated surface is preferred for the better protection it provides over oil blackening.
Deposition of a metal coating on the surface is
also possible. The most frequently used material is Zinc with a final passivation in Chrome
solution. Unfortunately, current methods of
electronically depositing metal coating from
aqueous solutions cause hydrogen embrittlement which cannot be completely avoided in
cases of higher tensile steels. This is the case
with disc springs and safety washers. Schnorr
therefore introduced a mechanical plating
process which proves to be very successful
over a number of years where no Hydrogen
embrittlement occurs.

general arrangement of components. The
windingspindle with ratchet is on the left.
A spring with almost a “zero” rate is
used for a negligible amount of force
variance despite the differences in the
cable diameter. Should one disc of
the stack fracture, the clamping force
would barely be affected and the unit
would still be operational.

This picture shows
M.A.N. steam turbine
condensers weighing
several hundred tons
being supported by a
very small number of
discs arranged in 3
stacks.
Improvement of sealing performance applies
to closing the gate until
the cone engages. The
springs compress and
the wedge forces the side
plate into close watertight contact with the valve
faces.
This device maintains a working
clearance, while aircraft adjuster
friction materials wear, to ensure
constant fluid displacement during
operation. The force/travel curve
of the springs within the confines of
such small assemblies must match
the hydraulic pressure and friction
bushings. The rate and accuracy
of Schnorr Disc Springs make them
ideal for these purposes.
This disc spring stack is used
in a pile-driving machine. The
operation is shown in three
typical phases.
1. Initial position
2. Impact - the springs
are compressed progressively from top to
bottom carried out by
pneumatic assistance. 
3. Return to initial position
also assisted by pneumatics.
This illustration shows a shear pin assembly
to a main shaft. To protect the shear pin from
transient shock overload while working the
connection link is fitted with double acting
SCHNORR disc spring stack.
The Demag unit shown is a standard
device on all cranes used to automatically compensate for load and angle.
Note the small size of the disc spring
stack when tremendous working loads
are considered.
