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.
the difference between the special-shaped spring and conventional spring is spring itself is irregular, the bending Angle and a large number of complex design.
Suitable for some special occasions.
spring available monolithic spring steel plate or multichip superposition, the cushioning and vibration damping performance is good, especially more plate spring vibration isolation performance is strong, it is mainly used for automobile, tractor and railway vehicle suspension.
