Variable diameter screw special-shaped
spring: it is used for special occasions, variable diameter of spring material generally for circular cross section, and mostly under compression load.
class special-shaped spring: the spring material for spring strip (
Or plate)
, on the device or general pressure machine, through the corresponding mould processing.
Leaf spring, waveform spring, light spring material thickness is thinner, and medium or large disc spring material thickness tends to thicker, use of this kind of spring is also very extensive.
in the convex screw compression special-shaped spring due to the small spring ring on both ends can be embedded into the circle in the middle, and so the larger deformation can be obtained.
For example, some of the convex type auto brake spring, and has been in a tight state at ordinary times, open the car valve, spring back deformation, drives the brake of automobile brake.
Haircut convex pusher is also used in helical spring this characteristic, the effective space to obtain larger deformation and stress.
volute special-shaped spring spiral similar to the role of the conical spiral special-shaped spring, it absorbed energy under pressure is big, because of manufacturing difficulties, only for the special case of limited space.
Plane volute spring coil number is more, the deformation is larger, can store larger energy, much used in the compression spring and instrumentation in energy storage element.
the concept of special-shaped spring:
with conventional spring slightly difference is spring skill is irregular, the bending Angle and a large number of complex design.
And manufacturing craft is also relatively have a requirement, equipment is also more requirements.
Usually computer machine winding.
Because of the winding Angle, bending, so the production speed is slow.
Because of its complexity, shaped spring production and processing, often can represent a company's technology level.
