Compression Springs
Figure 32.1 shows two alternative types of compression.
springs for which drawing conventions are used.
Note that the convention in each case is to draw the.
first and last two turns of the spring and to then link the.
space in between with a long dashed dotted narrow.
line. The simplified representation shows the coils of.
the springs drawn as single lines.
Note: If a rectangular section compression spring is.
required to be drawn then the appropriate shape will.
appear in view (e), view (d) will be modified with.
square corners and the Ø symbol in view (f) will be.
replaced by,.
A schematic drawing of a helical spring is shown in.
Fig. 32.2. This type of illustration can be used as.
a working drawing in order to save draughting time,.
with the appropriate dimensions and details added.
Figure 32.3 shows four of the most popular end.
formations used on compression springs. When
possible, grinding should be avoided, as it considerably.
increases spring costs.
Figure 32.4 shows a selection of compression.
springs, including valve springs for diesel engines and.
injection pumps.
