Abstract
The utility model relates to a bifilar helical disc spring, in particular to a spring adaptable to a high-speed spindle broach mechanism. A secondary helical coil (2) and a primary helical coil (1) are coiled wholly, and sections of the secondary helical coil (2) are inclined to sections of the primary helical coil (1) relatively. The bifilar helical disc spring is high in strength, low in friction, impact in structure and long in circuiting life, and is adaptable to the high-speed spindle broach mechanism and is easy to promote and applicate.
Description
Technical field
The utility model relates to a kind of component of machine, specifically a kind of spring that is applicable to the high-speed main spindle tool-broaching mechanism.
Background technique
In the prior art, general spring rate is low, and friction is big, and is loosely organized, and cycle life is short, and the tool-broaching mechanism that not too is fit to high-speed main spindle uses.
Summary of the invention
The utility model relates to a kind of double wrap spiral disk spring type spring, and it has solved the deficiencies in the prior art.
The utility model technical solution is to comprise one-level spiral pitch of the laps (1), it is characterized in that having deuterostrophies pitch of the laps (2) and one-level spiral pitch of the laps (1) and around, the cross section relative tilt of described deuterostrophies pitch of the laps (2) cross section and one-level spiral pitch of the laps (1).
Working principle of the present utility model is that this spring has two spiral pitch of the laps and around forming, shown in partial enlarged drawing, one-level spiral pitch of the laps cross section tilts on one side, and deuterostrophies pitch of the laps cross section is in addition on one side with spiral pitch of the laps relative tilt.This cross section is just as two dish springs to stacking.When spring was worked, the angle of inclination between two pitch of the laps was out of shape owing to stressed, flattened fully during the limit to stick together.The pitch of spiral also can diminish simultaneously.This structure has possessed the characteristics of the high rigidity of dish spring, simultaneously owing to being that whole coiling forms, so the phenomenon that multi-disc gathers into folds and dislocation occurs and tilt as the dish spring can not occur.This spring is particularly useful for the tool-broaching mechanism of high-speed main spindle, can effectively reduce the vibration of main shaft.Compare with dish spring group, stressed even, frictional force is little, the cycle life height.
Advantage of the present utility model is:
1, this structure spring has higher rigidity;
2, this structure spring friction is little, compact structure;
3, this structure spring has very high cycle life;
4, this structure spring is particularly useful for the tool-broaching mechanism of high-speed main spindle, can effectively guarantee the stability of vibration of main shaft.

Fig. 2 is that organigram amplifies in the utility model A portion.
Embodiment
According to shown in Figure 1, the utility model has deuterostrophies pitch of the laps (2) and one-level spiral pitch of the laps (1) and around, the cross section relative tilt of described deuterostrophies pitch of the laps (2) cross section and one-level spiral pitch of the laps (1) on the basis of existing one-level spiral pitch of the laps (1).
Claims (1)
1. double wrap spiral disk spring type spring, it comprises one-level spiral pitch of the laps (1), it is characterized in that having deuterostrophies pitch of the laps (2) and one-level spiral pitch of the laps (1) and around, the cross section relative tilt of described deuterostrophies pitch of the laps (2) cross section and one-level spiral pitch of the laps (1).
