The coupler has a simple structure, is low in cost, and has the anti-vibration function to a certain extent.

Description

Coupling

Technical field

The utility model relates to a kind of spare part in common use field, and more particularly, it relates to a kind of coupling.

Background technique

Coupling belongs to mechanical spare part in common use category, and two axles (driving shaft and driven shaft) that are used for connecting in different institutions make it common rotation with the mechanical parts of transmitting torque.In the power transmission of high-speed overload, it is the effect of dynamic performance that some coupling also has buffering, vibration damping and raising axle.Coupling is comprised of two halves, connects with driving shaft and driven shaft respectively.General power engine mostly links by means of coupling and working machine, is that the engineering goods axle is the most frequently used coupling member of transmission.some coupling also has buffering, vibration damping and raising axle are the effect of dynamic performance, development along with economic technology, to in reality technology coupling require also more and more higher, along with the raising that requires, some structures of coupling and the material of self etc. are a series of also to be needed to improve, the fabricating cost of so relative coupling of raising is also along with improve, some have often been ignored simple in structure, coupling with low cost, those are simple in structure, coupling with low cost can only adapt at those steady, on the low machine of rotating speed, some rotating speeds are slightly fast, working environment is rugged environment a little, corresponding having used that just is difficult to, but a lot of businessmans and producer's psychology are all understood, simple in structure, coupling with low cost is certainly existing certain defective, simple in structure, coupling with low cost self lacks and has certain shockproof function, a kind of coupler structure is simple, coupling with low cost and that have certain shockproof function is that a lot of small merchant is pursued.

The model utility content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of simple in structure, coupling that cost is low, shockproof.

for achieving the above object, the utility model provides following technological scheme: a kind of coupling, comprise the first half-coupling and the second half-coupling, described the first half-coupling and the second half-coupling end are equipped with a land, the first half-coupling and the second half-coupling are provided with a contiguous block, being provided with through hole in contiguous block communicates with the first half-coupling and the second half-coupling inner via hole, described contiguous block, first company's half-coupling land and the second half-coupling land are provided with the inclination attachment hole that communicates, described inclination attachment hole is downward-sloping and downward-sloping staggered around circle distribution from left to right from left to right, the first coupling, contiguous block is fixedly connected with the second coupling.

By adopting technique scheme, be provided with a contiguous block in the centre of the first and second half-couplings, by through hole UNICOM the first and second half-coupling intermediate throughholes in the middle of contiguous block, in driving shaft and driven axle insertion coupling, play one and lead the position effect, and by the linkage structure on contiguous block is improved, attachment hole is set to tilt, when when rotation, connect such structure by inclination and can make and have certain shockproof effect.

The utility model further is set to: be provided with at least respectively two spring bolts on described the first half-coupling and the second half-coupling.

By adopting technique scheme, on the first and second half-couplings, spring bolt is set, when inserting in coupling in driving shaft and driven axle, lock by spring bolt, make coupling play further fixation to driving shaft and driven axle.

The utility model further is set to: described spring bolt is symmetrical arranged take the through hole central shaft as symmetry axis.

By adopting technique scheme, spring bolt is symmetrical arranged, make spring bolt in locking, avoid active and the monolateral locking of driven axle, unstable when causing rotating, by being symmetrical arranged, can come balance driving shaft and driven axle to the symmetrical locking of spring bolt.

Embodiment

With reference to Fig. 1, the utility model embodiment is described further.

a kind of coupling, comprise the first half-coupling 1 and the second half-coupling 4, described the first half-coupling 1 and the second half-coupling 4 ends are equipped with a land 2, the first half-coupling 1 and the second half-coupling 4 are provided with a contiguous block 3, being provided with through hole in contiguous block 3 communicates with the first half-coupling 1 and the second half-coupling 4 inner via holes, described contiguous block 3, the land 2 of first company's half-coupling 1 and the land of the second half-coupling 4 are provided with the inclination attachment hole that communicates, described inclination attachment hole 5 is downward-sloping and downward-sloping staggered around circle distribution from left to right from left to right, the first half-coupling 1, contiguous block 3 is fixedly connected with the second half axial organs 4.By being equipped with a land 2 at the first half-coupling 1 and the second half-coupling 4 ends, and be provided with a contiguous block 3 in the middle of the first half-coupling 1 and the second half-coupling 4, when driving shaft inserts locking in the first half-coupling 1, carried out certain calibration function by 3 pairs of driving shafts of contiguous block, in like manner, when inserting the second half-coupling 4, driven axle also carried out calibration function.Utilize link by inclination attachment hole 5, the first half-coupling 1, contiguous block 3 and the second half-coupling 4 to be fixedly connected with, when driving shaft begins to rotate, driving the first half-coupling 1 rotates, the first half-coupling 1 passes through fixed connecting piece, driving the second half-coupling 4 rotates, then the second half-coupling 4 drives driven axle, has completed the working procedure of driving shaft drive driven axle.When driving shaft drives the first half-coupling 1 rotation, the first half-coupling 4 has given link a rotating force, because link left-to-right and right have a down dip to left-hand staggered, when having arrived link when the rotating force transmission, because such structural design has played the effect of a buffering, fast with respect to rotating speed, during work, bearing is unsettled, has also played a good shockproof effect.

At least be provided with respectively two spring bolts 6 on described the first half-coupling 1 and the second half-coupling 4.Spring bolt 6 is symmetrical arranged take the through hole central shaft as symmetry axis.At the first and second coupling, symmetrical spring bolt 6 is set, in driving shaft and driven axle insertion coupling, by spring bolt 6 locking driving shaft and driven axles, further driving shaft and driven axle are played fixation, and adopt and to be symmetrical arranged, can to driving shaft and driven axle parallelism play certain regulating action.

Because the utility model example has solved shockproof problem, the practicability of product and certain Security have been improved.

The above is only preferred embodiment of the present utility model, and in order to limit the utility model, those skilled in the art does not carry out common variation and replace should being included in protection domain of the present utility model in the technical solutions of the utility model scope.
