Abstract
The utility model discloses a coupling, in particular to a coupling with external and internal flanges, which is composed of an external flange semi-coupling, an internal flange semi-coupling, and a cylindrical pin. The coupling with the external and internal flanges is characterized in that a convex protection stop opening and a concave protection stop opening are arranged between the internal flange and the external flange; the cylindrical pin is a composite element which makes the plastic or the rubber as the base body; the long diameter specific value is 0.8-1.5, and the optimum value is 1-1.2. The utility model which has the advantages of simple structure, easy manufacturing, high capability, good elasticity, long life length, and low requirement to the installation precision has no axial component force; the coupling with the external and internal flanges is suitable for a large-size coupling, a medium-size coupling, a small-size coupling, a high-speed coupling, or a low-speed coupling, and the coupling with the external and internal flanges is especially favorable for a mini-type coupling.
Description
The utility model is about coupling, the particularly improvement of inside and outside flange coupling design.
Use the flexible loop pillar pin of coupling coupling very widely aborning, its shortcoming is that processed complex and elastic ring are fragile.Next is the nylon pin coupler, and this coupling has solved the life problems of pin, processes also very simply, but disadvantage is to have axial thrust load and elasticity little.Agricultural pawl type elastic coupling flexible coupling, the life-span is longer, but mounting or dismounting inconvenience, and only be suitable for the high rotating speed occasion of small-power.
The inside and outside flange coupling that occur the beginning of the fifties (seeing 126 pages of Ivanov works " transmission coupling ") is a kind of axial thrust load simple in structure, easy to manufacture, no, radial force complete equilibrium, the good coupling of elasticity.But why do not promoted in decades? analyzing reason has three, the major diameter ratio of (1) straight pin design too big (reaching 2.86) this just limited the installation EE Error Excepted of coupling.(2) for to prevent that the groove edge of outward flange from entering in the groove of inner flange, the pitch of straight pin is 2.3 times of its diameter, has reduced the number of straight pin virtually, thereby greatly reduces the bearing capacity of coupling.When (3) straight pin was made for homogenous material rubber, shear ability was poor, has limited the bearing capacity of coupling.
The coupling of advantages such as the purpose of this utility model provides the advantage of simple, easy to manufacture, the no axial thrust load of a kind of existing structure, good springiness, has the straight pin life-span long again, and installation precision is less demanding, and bearing capacity is big.
The utility model is by reducing the major diameter ratio of straight pin, between inside and outside flange, increase protruding, spill protection seam, reduce the pitch diameter of straight pin, increase the number of straight pin, the edge chamfering or the rounding of arc groove are concentrated to reduce stress, and the structure of specialized designs straight pin, adopt composite material, measures such as the resistance to wearing of straight pin, anti-shear ability realize to improve.
Inside and outside flange coupling, by the outward flange half-coupling and with this half-coupling inside and outside suit the inner flange half-coupling and pack into by half outward flange half in the cylindrical hole that inner flange constitutes, and the straight pin that adapts of cylindrical hole size is formed therewith.The straight pin that is characterised in that of the present utility model is that what be made of wearing layer, anti-shearing layer and elastic layer is the composite component of matrix with rubber or plastics.Its major diameter ratio is 0.8～1.5, and optimum value is 1～1.2.
Enter in the semi-circle groove of inner flange the protection seam that between outward flange and inner flange, has convex-concave to match for the edge that prevents outward flange semi-circle groove.
For preventing that straight pin from producing excessive stress and concentrating, two edges all pass through chamfering or rounding between the semi-circle groove of inside and outside flange and groove.
For improving resistance to wearing and anti-shear ability of straight pin, its wearing layer of straight pin that with rubber is matrix is the infantees layer that rubber canvas constitutes, anti-shearing layer alternately is entwined along the left and right Hand of spiral of the circumference of straight pin by textile rope or finer wire, should have rubber to fill a vacancy between rope and rope or steel wire and the steel wire, elastic layer is a rubber.
So mainly being to improve its elasticity when straight pin is matrix with plastics, is the thick hollow plastic sleeve of 2～20mm be designed to wearing layer, its anti-shearing layer and elastic layer be a metallic cylindrically coiled spring the two be set in together.
When the straight pin diameter is big, such as greater than 40mm the time,, be bumped into a hollow circular cylinder at the straight pin central part, guaranteeing to have reliable anti-shear ability, this hollow circular cylinder is with engineering plastics or metal manufacturing.
The utility model is compared with widely used pin coupler: have simple in structure, part is few, easy to manufacture, install easy to adjust, change easy, the advantages such as elasticity is big, the life-span is long, no axial thrust load of pin.
Inside and outside flange coupling of the present utility model is applicable to large, medium and small type coupling, be specially adapted to the coupling of microminiature coupling and single piece production, when the coupling that is used for single piece production adds man-hour, the cylinder pin hole that the semi-circle groove of inside and outside flange is formed is processed simultaneously, Deng processing, on inside and outside flange half-coupling, make corresponding mark, as long as still can sit in the right seat when installing, then the pitch to cylinder pin hole can allow bigger error, the center parallelism of cylinder pin hole also can allow bigger error, so bring great convenience to processing.
