Description
Technical field
The utility model relates to a kind of butterfly spring, and more particularly, it relates to a kind of butterfly spring of optimizing rear enhancing load.
Background technique
Belleville spring has another name called Beile Wei Er spring washer, it is the gasket type spring with metal blank or the truncated cone shape cross section that forms of forging and stamping blank, belleville spring is tapered in the axial direction and bears the special spring of load, after bearing load deformation, save certain potential energy, when relaxing appears in bolt, belleville spring release portion potential energy is to keep the pressure between flange connection to reach seal request.Belleville spring stress distribution is evenly successively decreased from inside to outside, can realize the effect of the high equilibrant force of low stroke.
At present, common belleville spring on market is the belleville spring with radial groove, radially output several equally distributed grooves, groove can be outputed by the outside circular direction of endoporus, also can to endoporus direction, be outputed by cylindrical, conventionally butterfly spring is sheathed on axle excircle and uses, installation form and structural feature due to butterfly spring, when actual working state, a pair of butterfly spring external diameter surface of contact can not contact completely, and be local contact or single edge contact, cause butterfly spring local pressure or monolateral stressed, cause butterfly spring torsional deformation and tear, thereby cause butterfly spring working strength to decline at double.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of butterfly spring that strengthens load by change structure.
For achieving the above object, the utility model provides following technological scheme:
A kind of butterfly spring, comprise spring body, described spring body is provided with the hole coordinating with axle, described spring body comprises the first spring section and the second spring section, between described the first spring section and the second spring section, form the 3rd spring section, described the first elasticity, the second spring section and the 3rd spring section are all and are wholely set, described the first adjacent both sides of spring section are formed with the first angular flexibility, described the second adjacent both sides of spring section are formed with the second angular flexibility, one side of described the first spring section is connected in the second spring section adjacent edge and is formed with the 3rd angular flexibility, described angular flexibility is all formed with stressed limit, described the first angular flexibility with the second angular flexibility opening towards consistent, described the 3rd angular flexibility and the first angular flexibility and the second angular flexibility opening are towards the opposite.
By adopting technique scheme, change the structure of spring body, increase elastic member and increase its load-carrying ability, appealing three spring section is and is wholely set, power is dispersed to each spring section, each spring section forms angular flexibility between any two, each angular flexibility forms stressed limit, three stressed limits are respectively monolateral stressed, make butterfly spring stress equalization, increase butterfly spring useful load, thereby prevent that butterfly bullet torsional deformation from affecting normal function, said structure can be avoided butterfly spring local pressure and monolateral stressed problem, increases the working strength of butterfly spring.
The utility model is further set to: described single spring section cross section is V-type groove, and described the first angular flexibility, the second angular flexibility and the 3rd angular flexibility angle all equate.
By adopting technique scheme, the every adjacent both sides of V-type groove are formed with angular flexibility, and each angular flexibility is respectively monolateral bearing pressure, make the bearing capacity of each spring section balanced, thereby have promoted the load-carrying ability of whole elastic region, have improved the intensity of butterfly spring.
The utility model is further set to: described spring body is provided with abutting part along axis cover set direction, and described abutting part is set to horizontal plane.
By adopting technique scheme, butterfly spring is used in combination for being stacked, the abutting part that is horizontal plane setting can change the single edge contact limit of each butterfly spring into plane contact, improve stressing conditions, overcome unstability, the torsional deformation that spring causes under single edge contact stressing conditions and the state such as torn, guaranteed the working life of its butterfly spring.

Embodiment
Referring to figs. 1 through Fig. 2, the utility model butterfly spring embodiment is described further.
A kind of butterfly spring, comprise spring body, described spring body is provided with the hole coordinating with axle, described spring body is provided with some elastic regions, described elastic region is provided with the first spring section 1 and the second spring section 2, between described the first spring section 1 and the second spring section 2, form the 3rd spring section 3, described the first elasticity, the second spring section 2 and the 3rd spring section 3 are all and are wholely set, described the first adjacent both sides of spring section 1 are formed with the first angular flexibility 4, described the second adjacent both sides of spring section 2 are formed with the second angular flexibility 5, one side of described the first spring section 1 is connected in the second spring section 2 adjacent edges and is formed with the 3rd angular flexibility 6, described angular flexibility is all formed with stressed limit, described the first angular flexibility 4 with the second angular flexibility 5 openings towards consistent, described the 3rd angular flexibility 6 and the first angular flexibility 4 and the second angular flexibility 5 openings are towards the opposite, described single angular flexibility is all formed with stressed limit.
The every adjacent both sides of described V-type groove 7 are formed with angular flexibility, each angular flexibility is respectively monolateral bearing pressure, make the bearing capacity of each spring section balanced, each angular flexibility forms spring section, each spring section is combined into Yi Ge integral, flexible district, the elastic force that the elastic region of this butterfly spring is supplied with is common butterfly spring three times, greatly improved butterfly spring useful load.
