Abstract
The utility model discloses a zigzag spring coupler with a seal positioning structure. The zigzag spring coupler mainly comprises a half-coupling, a zigzag spring and a housing as well as a seal positioning structure, wherein the seal positioning structure is a circular part, the cross section of the circular part along the radius is of a 7-shaped structure, the two sides of the 7-shaped structure are respectively two rectangles; the long sides of the two rectangles are mutually vertical; the long sides of one of the two rectangles are parallel to a middle shaft of the circular part to form a vertical ring structure of the seal positioning structure; the other one rectangle is connected with one side far away from the central shaft to form a bottom ring structure of the seal positioning structure; the seal positioning structure is sheathed on the half-coupling; the vertical ring structure is matched with the outer diameter of the long end of the half-coupling; the bottom ring structure is arranged between the top of the zigzag spring and the housing; and the installation position of the zigzag spring is determined through the seal positioning structure, thereby the service life of the zigzag spring coupler is effectively increased.
Description
Technical field
The utility model relates to mechanical field, particularly a kind of snake spring coupling with the sealing position structure.
Background technique
The basic structure of snake spring coupling is to comprise two half-couplinves; Two half-couplings joint near the place be provided with the tooth of convexity; The snake spring is embedded in the teeth groove, and the case that is with layer of metal again in the outside of snake spring shields, and is provided with seal ring between the long end external diameter of case and half-coupling.The characteristics of this snake spring coupling are with the serpentine spring to be elastic element, when having possessed than strong elasticity, have greatly improved snake spring coupling transmitting torque, are widely used in heavy machinery and universal machine occasion.This snake spring coupling, axially, radially having good compensation ability snake spring coupling with angle, to bear moment of torsion bigger, is applicable to heavy machinery and universal machine occasion.Also just because of this coupling leave axially, angle, radial compensation; Cause production gap between serpentine spring and case; Can cause serpentine spring to move around during work case is produced impact; Causing case to damage can not seal and draining, makes serpentine spring and fluted disc lose lubricated and the cooling work efficiency, causes serpentine spring or tooth to damage.
The model utility content
In order to address the above problem, the utility model provides a kind of snake spring coupling with the sealing position structure, and the mounting point of its serpentine spring is confirmed, the working life of having improved snake spring coupling effectively.
The technological scheme of the employing of the utility model is: a kind of snake spring coupling with the sealing position structure, mainly comprise half-coupling, serpentine spring and case, and it is characterized in that also comprising a sealing position structure; Said sealing position structure is a ring-shaped article, and said ring-shaped article is processed by rubber parts, and said ring-shaped article is " 7 " type structure along the cross section of radius; The both sides of said " 7 " type structure are respectively two rectangulars; Two rectangular appearance are vertical mutually, and one of them rectangular length is parallel with the axis of ring-shaped article, constitute the vertical ring structure of said sealing position structure; Another rectangular is connected the side away from central shaft; Constitute the base ring structure of said sealing position structure, said vertical ring structure matches with the long end external diameter of half-coupling, and said base ring structure is between the top and case of snake spring.
Described sealing position structure is preferably processed by rubber, particularly preferably is by butyronitrile rubber to press notes to process, and it draws high by force can reach 15-30/MPa; But spring-back force 60-65%; And wear resistance is relatively good.
The beneficial effect of the utility model is: between snake spring and case, added the sealing positioning device; Through the location of seal arrangement to serpentine spring, avoided serpentine spring to move around and avoided the impact of serpentine spring case, improved coupling working life; Further; Under the situation that seal ring damages, the sealing positioning device has good sealing effect, and guaranteeing can draining.
Description of drawings
Fig. 1 is the sectional drawing of the utility model;
Fig. 2 is the schematic representation of sealing positioning device;
Fig. 3 is the sectional view of sealing positioning device along radius.
Embodiment
Below be an embodiment of the utility model, the actual use of the utility model is not limited thereto embodiment.
In conjunction with Fig. 1 to Fig. 3, a kind of snake spring coupling with the sealing position structure mainly comprises half-coupling 1, serpentine spring 2 and case 3; Be provided with seal ring 5 between case and between the half-coupling major diameter outer end, also comprise a sealing position structure 4, said sealing position structure is a ring-shaped article; Said ring-shaped article is " 7 " type structure along the cross section of radius, and the both sides of said " 7 " type structure are respectively two rectangulars, and two rectangular appearance are vertical mutually; The length of one of them rectangular A is parallel with the axis of ring-shaped article; Constitute the vertical ring structure 41 of said sealing position structure, the length of another rectangular B is connected the side away from central shaft, constitutes the base ring structure 42 of said sealing position structure; Said sealing position structure be enclosed within said half-coupling on; Said vertical ring structure matches with the long end external diameter of half-coupling, and said base ring structure is between the top and case of snake spring
Seal arrangement has been avoided serpentine spring to move around and has been avoided the impact of serpentine spring to case the location of serpentine spring, has improved coupling working life.The sealing positioning device plays seal action simultaneously, and particularly under the situation that seal ring damages, the sealing positioning device has good sealing effect, and guaranteeing can draining.When in coupling, having abundant oil mass, improved working life under its lubricity and the good situation of cooling property.
Claims (2)
1. the snake spring coupling with the sealing position structure mainly comprises half-coupling, serpentine spring and case, it is characterized in that also comprising a sealing position structure; Said sealing position structure is a ring-shaped article; Said ring-shaped article is " 7 " type structure along the cross section of radius, and the both sides of said " 7 " type structure are respectively two rectangulars, and two rectangular appearance are vertical mutually; One of them rectangular length is parallel with the axis of ring-shaped article; Constitute the vertical ring structure of said sealing position structure, another rectangular is connected the side away from central shaft, constitutes the base ring structure of said sealing position structure; Said vertical ring structure matches with the long end external diameter of half-coupling, and said base ring structure is between the top and said case of snake spring.
