Abstract

A kind of better butterfly spring of elasticity, including spring axis and the multiple tab (s) being set on spring axis, there is the first contact platform in shaft end in disk over spring, it contacts by platform as the first elastic slope, it is the second contact platform by first elastic slope, it is the second elastic slope by second contact platform, second elastic slope end is that third contacts platform, the utility model solves the problems, such as that current butterfly spring elasticity is not enough to reach industrial Seiko production requirement, and the utility model is simple and practical in structure, has great market popularization value.

Description

A kind of better butterfly spring of elasticity
Technical field
The utility model relates to Special spring, especially a kind of better butterfly spring of elasticity.
Background technique
As shown in Figures 1 and 2, butterfly spring is that annulus gasket sample is similar to outside one kind, and the machine of the different metal of material Tool accessory ----Special spring.Again because of outer likeness in form dishes shape, therefore claim disk spring.
In general, it is to provide sufficiently resilient stretching, extension by a considerable amount of superpositions, and play a role.
Due to there is the features such as variation rigidity characteristic and install compact, it is widely used in mechanical equipment industry, petroleum industry, automobile The fields such as industry and aerospace industry, very wide range is instead of cylindrical helical spring.
Existing butterfly spring elasticity is not enough to reach industrial Seiko production requirement.
Summary of the invention
The utility model provides a kind of better butterfly spring of elasticity to solve above-mentioned technical problem.
The technical solution of the utility model is achieved in that
A kind of better butterfly spring of elasticity, including spring axis and the multiple tab (s) being set on spring axis, disk There is the first contact platform in shaft end in over spring, and it is the second contact platform by the first elastic slope, second connects that contact platform side, which is the first elastic slope, It touches for the second elastic slope by platform, the second elastic slope end is that third contacts platform.
The third contact platform is shaft end in disk short round spring.
Described first elastic slope is obliquely.
Described second elastic slope is obliquely.
The first contact platform is flat type.
The second contact platform is arc.
The utility model solves the problems, such as that current butterfly spring elasticity is not enough to reach industrial Seiko production requirement, and this Utility model is simple and practical in structure, has great market popularization value.

Specific embodiment
As shown in Figures 3 and 4, the utility model includes spring axis and multiple tab (s) for being set on spring axis, dish There is the first contact platform in shaft end in piece over spring, is the first elastic slope by contact platform, is the second contact platform by the first elastic slope, and second It contacts for the second elastic slope by platform, the second elastic slope end is that third contacts platform, and shown third contact platform is in disk short round spring Shaft end, the shown first elastic slope are that obliquely, the shown second elastic slope is that obliquely, shown first contact platform is flat type, institute Show that the second contact platform is arc.
The working principle of the utility model be it is such, the first contact platform to the first elastic slope on disk is the first bullet Property area, since the small length of the gradient of the first elastic region is low, when the first second compression of butterfly spring is the first elastic region of compression, and second Contacting platform to the second elastic slope is the second elastic region, and third contact platform completely attaches to after the first elastic region is compressed completely, then The second elastic region can just be compressed, at this time compressing force must be whole the first elastic regions of disk summation more than could compress the second bullet Property area, and the contact platform of the second elastic region be arc and gradient long length it is short, compressing force is far longer than the first elastic region, until After third contact platform completely attaches to after second elastic region is compressed completely, compression is completed, at this point, the second contact platform completely attaches to be formed Straight, two elastic regions of each disk are compressed completely, are rebounded thereafter.
And the small length of the disk gradient in the prior art is big, and only one Hookean region, elastic force is practical much smaller than this It is novel.
