Abstract
The utility model discloses a two coil spring revolves the positive derotation of spring by the list that two bursts of big or small shapes are unanimous and closes and form, and the structure is inseparable, has both kept the high energy storage and the high reaction rate of spring, has remedied sub -thread spring durability and firmness shortcoming inadequately again.
Description
Technical field
The utility model relates to a kind of mechanical parts, particularly relates to a kind of double-helix spring.
Background technique
Spring is a kind of quite common part in machinery, but its effect is very important, and particularly in precision processing machine, to the compression resistance of spring, reaction velocity has quite high requirement.Although the common spring that singly revolves has good elastic reaction force, the high pressure of precision processing machine can not be born.So generally use belleville spring at present, although belleville spring compression capability strengthens, there is larger two problems: one, because elastic deformability is not enough, easily rupture, working life is short.Two, reaction velocity is fast not, does not reach machine work requirement.
Summary of the invention
The utility model provide a kind of by two bursts of size shape consistent singly revolve the positive and negative double-helix spring screwed of spring, close structure, both maintained the high energy storage of spring and high reaction velocity, increased again serviceability and the fastness of spring.
A kind of double-helix spring, mainly comprise spring body, described spring body singly revolves spring shaft by two strands and forms to positive and negative screwing, two bursts of size shape of singly revolving spring are completely the same, and double-helix spring, complementary by type position during external force extruding, forms a paradox, when one spring is under pressure, another strand of spring can produce a reaction force to it, considerably increases the compression capability of spring, possesses again spring reset capability fast.
Accompanying drawing explanation
Fig. 1 is the generalized section of a kind of double-helix spring of the utility model;
Embodiment
As shown in Figure 1, the utility model is a kind of double-helix spring, mainly comprises spring body 1, described spring body by two bursts of size shape on all four singly revolve spring 2 axially positive and negative screwing form.First produce with identical material that two size shape are on all four singly revolves spring 2, then singly revolving spring 2 with a dextrorotation, the direction of a derotation screws mutually, until two sub-thread springs are locked together closely.
Claims (2)
1. a double-helix spring, mainly comprises spring body (1), it is characterized in that: described spring body (1) singly revolves axial positive and negative the screwing of spring (2) by two strands and forms.
2. a kind of double-helix spring as claimed in claim 1, is characterized in that: described two bursts size shape of singly revolving spring (2) are completely the same.
