Abstract
The utility model discloses a kind of combined type belleville spring, the use that has mainly solved common belleville spring is single, can only be used in the bolt of single specification, and poor sealing performance, resistance property is not high, the shortcoming that life-span is short, its technological scheme is mainly that two butterfly springs of size and a helical compression spring are used in combination, on large belleville spring sidewall, have groove, helical compression spring and little belleville spring are set in groove, by stretching of little butterfly spring in the elastic force control flume of helical compression spring, thereby control the size of internal diameter, when this butterfly spring and bolt are used in conjunction with, helical compression spring promotes inner side saucer shape spring inside diameter and bolt close contact improves sealing, belleville spring outer surface is surrounded by one deck elastic caoutchouc, in the time that receiving that moment resists, belleville spring can play buffer function, thereby improve the resistance performance of belleville spring, increase the working life of belleville spring.
Description
Technical field
The utility model relates to a kind of composite spring, is mainly a kind of combined type belleville spring.
Background technique
Belleville spring is gasket type spring truncated cone shape cross section and that bear load forming with metal blank or forging and stamping blank, often coordinate and install and use with bolt, bearing after load deformation, save certain potential energy, in the time that relaxing appears in bolt, the pressure between the member that belleville spring release portion potential energy is installed with needs such as maintenance flanges reaches seal request.
At present, the belleville spring having on market, shape and structure are all similar, these belleville springs have some as single in use, can only be used in the bolt of same specification, poor sealing performance, resistance property is not high, working life short grade shortcoming, limited the using scope of belleville spring.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of one multiplex, good seal performance, resistance performance is high, the combined type belleville spring of long service life, this combined type butterfly spring is normally solely used on bolt, is not suitable for two or more combined type belleville spring stacks and uses.
For achieving the above object, the utility model provides following technological scheme: a kind of combined type belleville spring, comprise large belleville spring, on the sidewall of described large belleville spring, have with the opening of the oblique identical annular groove of sidewall and described annular groove towards the one side setting of path direction, in groove, be provided with helical compression spring and little belleville spring, helical compression spring one end is fixedly connected with the groove bottom of annular groove and the other end of helical compression spring is fixedly connected with little belleville spring.
By adopting technique scheme, adopt on large belleville spring and offer groove, in groove, be provided with helical compression spring and little butterfly spring, helical compression spring is fixedly connected with little butterfly spring respectively at large belleville spring, in the time that the diameter of bolt is greater than the existing internal diameter of butterfly spring, little butterfly spring compression helical compression spring inside contracts to large dish-shaped spring groove, it is large to being enclosed within on bolt that thereby the internal diameter that makes belleville spring becomes, make belleville spring and bolt close contact, by stretching of little butterfly spring in the elastic force control flume of helical compression spring, the size that can control belleville spring internal diameter can be applicable to the bolt of plurality of specifications, improve again the sealability of belleville spring.
The utility model is further set to: the elastic caoutchouc that the outer surface of described butterfly spring has one deck to be fixedly connected with belleville spring.
By adopting technique scheme, belleville spring outside is surrounded by one deck elastic caoutchouc, rubber is fixedly connected with belleville spring, belleville spring is in the time being subject to moment percussion, elastic caoutchouc can play certain buffer function, alleviate the suffered impact force of belleville spring, thereby improve the resistance performance of belleville spring, improve its working life simultaneously.
The utility model is further set to: the wall thickness of described little butterfly spring is suitable with the annular groove of large belleville spring.
By adopting technique scheme, the wall thickness of little butterfly spring is suitable with the annular groove of large belleville spring, has ensured that little butterfly spring can not rock in large dish-shaped spring shackle connected in star, has improved the working stability of composite spring.
The utility model is further set to: in described large dish-shaped spring groove, be fixed with the column that some directions are identical with groove direction, described helical compression spring is enclosed within on column.
By adopting technique scheme, helical compression spring is enclosed within on the column in large dish-shaped spring groove, and rolling while having avoided helical compression spring work, further improves the working stability of combined type belleville spring, can also reduce the usage quantity of helical compression spring.
Brief description of the drawings
Fig. 1 is the structural drawing of a kind of combined type belleville spring of the utility model.
In accompanying drawing, 1. large belleville spring; 2. little butterfly spring; 3. helical compression spring; 4. annular groove; 5. column.
Embodiment
A kind of combined type belleville spring, comprise large belleville spring 1, little belleville spring 2, helical compression spring 3, annular groove 4, column 5, column 5 is arranged in annular groove 4, helical compression spring 3 is directly enclosed within on column 5, helical compression spring two ends are adhesively fixed and are connected with little belleville spring 2 respectively at large belleville spring 1, in the time that the diameter of bolt is greater than the existing internal diameter of butterfly spring, little butterfly spring compression helical compression spring inside contracts to large dish-shaped spring groove, it is large to being enclosed within on bolt that thereby the internal diameter that makes belleville spring becomes, make belleville spring and bolt close contact, by helical compression spring
In elastic force control flume, little butterfly spring is flexible, and the size that can control belleville spring internal diameter can be applicable to the bolt of plurality of specifications, has improved again the sealability of belleville spring.
Belleville spring outside is surrounded by one deck elastic caoutchouc, rubber is adhesively fixed and is connected with belleville spring, belleville spring is in the time being subject to moment percussion, elastic caoutchouc can play certain buffer function, alleviate the suffered impact force of belleville spring, thereby the resistance performance that improves belleville spring improves its working life simultaneously.
The wall thickness of little butterfly spring is suitable with the annular groove of large belleville spring, has ensured that little butterfly spring can not rock in large dish-shaped spring shackle connected in star, has improved the working stability of composite spring.
In large dish-shaped spring shackle connected in star, be provided with the column that some directions are identical with groove direction, column and annular groove bottom are adhesively fixed, because column is used for fixing helical compression spring, the column being bonded in annular groove can not separate with annular groove bottom because come off by very large pulling force.
Claims (4)
